Flashforge Creator 5 Known Issues and How to Fix Them

The Flashforge Creator 5 is an open-frame CoreXY printer with a 256×256×256 mm build volume and four independent direct-drive FlashSwap toolheads that swap in 6–7 seconds. Firmware 1.7.3 shipped on 11 April 2026, the first units went out in May, and Flashforge has shipped eight firmware releases in four months. Here are 25 problems that made it into the official Flashforge wiki, the error code list and owner reports over those four months: 21 covered in depth, plus four short ones at the end.

Everything below is specific to the Creator 5 and Creator 5 Pro: frame geometry, toolchanger behavior, purge handling, the eddy-current leveling system and the Flash Studio slicer. Generic FDM headaches — first layer, stringing, warping, clogs — live in separate cross-printer guides, linked at the end.

1. Squares print as rhombuses: XY axis skew

This is the loudest complaint about the Creator 5 and the dominant thread topic in owner forums. The X and Y axes are not at 90°, so a printed square comes out as a rhombus with unequal diagonals. Models look fine at a glance, but holes go oval, threads seize, lids don't sit on boxes and multi-part assemblies refuse to mate.

Owner measurements: 0.6 mm diagonal difference on a 100×100 mm square (two separate units), 1.2 mm on an 82×82 mm square and roughly 5 mm on a 220×220 mm part. One owner got 0.2 mm across a diagonal of just 42 mm — enough to seize the thread in a test cube. The accepted community tolerance is 0.1 mm per 100 mm. For reference, the same threads report under 0.1 mm on a Snapmaker U1 at 82×82 mm and zero deviation on a Creality K2 Plus across a 475 mm diagonal.

The cause is structural. The round Y-axis rods are pressed straight into the frame rather than into adjustable brackets the way Creality does it. If the frame takes a set, the rods follow it and the X rail stops being perpendicular. There is no factory fix: Flashforge ships no skew correction tool.

1. Measure the outer diagonals of the top frame with a tape as soon as you unbox. Good units measured 58.3 × 58.3 cm; a skewed one came in at 58 × 58.5 cm. A mismatch here alone justifies a return claim.
2. Quick check without printing: pull the carriage off its endstop and use feeler gauges on the gap at the front and rear corners. Unequal gaps are the skew, measured directly.
3. Rule out over-tensioned belts first: loosen the screws on the L-brackets at the front and rear right corners, work the axes and head firmly against their stops, then retighten. Flashforge documents the procedure under XY belt tension adjustment.
4. Print an orthogonality test with chamfered corners — sharp corners with a seam on them measure badly — and check the diagonals with calipers.
5. If the skew exceeds tolerance and your return window is open, ask for a replacement. This is a manufacturing defect, not a setting.
6. If returning is no longer an option, the software route is Klipper skew correction: add [skew_correction] to printer.cfg, run SET_SKEW XY=AC,BD,AD with your measurements, then SKEW_PROFILE SAVE=my_skew_profile and SAVE_CONFIG, and add SKEW_PROFILE LOAD=my_skew_profile to your start G-code and SET_SKEW CLEAR=1 to the end. Docs live at klipper3d.org.

An important caveat: not every unit is affected. The same threads include an owner whose orthogonality test came out at 0.11 mm. But every unit needs checking, and ideally in the first few days while buyer protection still applies.

2. The bed arrives warped: 0.6 mm and worse

One corner of the first layer is squashed translucent while the other hangs in the air. In bad cases the printer refuses outright with E0148 "Z-Offset Variance Out of Range" — the spread between the highest and lowest probed points exceeded the limit.

Two owners independently measured 0.6 and 0.61 mm straight out of the box. One got down to 0.128 mm using the nuts plus tape shims; the other only reached 0.4 mm with nuts alone. The plane is set by four adjustment nuts underneath, and the bed rides on three rods and three lead screws driven by a single stepper through one belt. There's nothing to fix in software here: those four nuts are the only adjustment you have.

1. Confirm the three shipping screws holding the bed are out. While they're in, the bed is clamped and no adjustment will help.
2. Run Leveling and read the map: what matters is the delta between the highest and lowest points. The mesh is 10×10 — 100 points — and the bed soaks at target temperature for five minutes before probing starts.
3. Turn the four nuts under the bed a quarter turn at a time toward a smaller spread, re-probing the mesh after each pass.
4. When the nuts run out of travel, shim under the plate with heat-resistant tape, one or two squares at a time. That's exactly how one owner went from 0.61 mm to 0.128 mm.
5. If you hit E0042 or E0112 instead, check the opposite: over-tightened nuts. Flashforge explicitly allows backing all four off by 1–2 turns.

3. The nozzle punches the plate and knocks tools off during offset calibration

A day-one classic. An owner in the official Flashforge Creator 5 group described it word for word: three calibration runs, and each time the printer knocked toolheads off and punched holes in the bed. It always failed on the last step — extruder offset calibration. Or the printer simply throws E0147 "PEI Steel Sheet Not Removed".

It isn't the printer's fault. Offset calibration probes a calibration disc hidden underneath the flexible steel plate. The plate has to come off — both the official calibration guide and the startup wizard say so. Leave it on and the nozzle drives into it instead of the disc.

1. Remove the flexible PEI plate from the heatbed before starting Extruder Offset Calibration.
2. Check that no plastic residue is stuck to the nozzles or the heatbed: debris on a nozzle tip corrupts the probe data.
3. Start the routine and leave the machine alone until the completion message appears. The five-minute temperature soak is normal, not a hang.
4. Re-run it after every hotend swap, after any nozzle-to-bed or nozzle-to-model collision, and whenever colors visibly misalign.
5. If the printer gouges a groove and complains about a foreign object even with a clean, bare bed, that's a sensor failure — talk to your seller.

4. Tools won't pick up or dock: errors E0127–E0146

The print stops exactly at a color change and the screen shows a code with a tool number. The tool may stay stuck on the carriage or refuse to leave the dock. In one week-long Creator 5 Pro review a head failed to return to its slot mid-swap and ruined the print, with no identifiable cause.

The mechanism is simple: the tool sits on magnets, the carriage grabs a round boss on its back and aligns on three pins, and a locking motor clamps it. One of four things breaks — the locking motor, the extruder PCB, the harness, or a magnet is simply missing. A missing carriage or dock magnet is listed outright among the causes of E0139, E0140, E0143 and E0144 in the official error code list.

1. Check that every tool is in its own slot. Codes E0131–E0134 "Slot Occupied" mean exactly that: the tools got swapped around.
2. Disengage the locking motor, home the carriage and retry the pickup. That's the official fix for E0142 and E0143.
3. Inspect the extruder carriage magnet and the dock magnet — they can be missing from the factory.
4. Check the extruder harness for chafing and reseat every connector.
5. If the code keeps coming back on the same tool, the official order of replacement is locking motor, then extruder PCB, then harness.
6. Update to at least 1.7.8 (27 April 2026): it reworked the error prompts for toolhead pick-and-place, so the code actually tells you what failed.

5. Layer marks on one color: the tool isn't fully locked

A sneaky defect, because it reads like an extrusion problem. One specific nozzle produces a distinct layer pattern that visibly changes as the model gets taller. Yet run that same nozzle on its own and there's no under-extrusion and no extruder strain at all.

Flashforge's own diagnosis is incomplete grasping or locking: the joint between the nozzle and its seat isn't rigid enough, and normal printing forces are sufficient to shift it. Telling it apart from ordinary layer shifting is easy — this defect belongs to one color, not to the whole model.

1. Open Move & Calibrate → Calibrate and pick Extruder Position Calibration.
2. Select the problem tool and push the carriage into the target position by hand until it seats; the extruder locks automatically and the Start Calibration button becomes active.
3. Keep your hands out of the motion area and run it.
4. If the layer pattern comes back, check that tool's locking motor and magnets against codes E0139–E0144.

6. One color sits offset from the rest

Whole layers of one color have shifted relative to their neighbours — a clean lateral offset, not vertical banding. On a multicolor model it jumps out immediately: the color bands don't line up at the edges.

Officially there are three causes: the calibration routine itself failing, skipping recalibration after a hotend teardown, and a dirty nozzle at calibration time. The last one is by far the most common — plastic stuck to the tip moves the contact point, and the printer memorizes a wrong offset.

1. Unload filament from all hotends so no fresh ooze forms on the tips.
2. Clean all four nozzle faces properly.
3. Remove the PEI plate and run Extruder Offset Calibration.
4. If you took a hotend apart, calibration is mandatory — no exceptions.
5. Offset still there after a clean calibration? The remaining causes are in the sensors; that's a support ticket.

7. The carriage cable presses on the T4 toolhead cable

A design miss on early units that Flashforge acknowledged itself. When the extruder carriage travels to the front-left position, its own cable is very likely to lie across the T4 toolhead cable. The two pull on each other on every pass, and over time they chafe.

1. Download the Extruder Mount Cable Clip file from the official wiki.
2. Print it in PLA or PETG. Go PETG on the Pro — the enclosed chamber runs hotter.
3. Fit it over the cable and push it down until fully seated, or it'll pop off on the first pass.
4. The community alternative is the Creator 5/5 Pro Toolhead Cable Strain Relief Guide on MakerWorld. It adds a retaining clip so the cable can't fall out, and the rounded inner edge goes up so the cable doesn't rub on a sharp corner.

Newer revisions already have this reworked — a commenter on 8 August 2026 reported the printed part simply didn't fit their new machine. That's good news: if the clip won't seat, you have the fixed hardware.

8. The prime tower weighs more than the model

Low waste is the whole reason to buy this machine: a toolchanger swaps the entire head instead of forcing a new color through one nozzle, so purging should be minimal. On Flashforge's own filament it is — roughly 0.5 g per color change. On third-party filament the tower balloons to single-nozzle proportions.

Numbers from reviews: a 33 g model produced a 44 g purge block — heavier than the part itself. A four-color 16 g Benchy generated 36 g of waste on defaults; the same reviewer cut it to 15 g and then 8 g in two optimization passes. The reason is stated plainly: Flashforge tuned flush volumes only for its own filament profiles, and everything else falls back to single-nozzle values. The setting is buried deep in the slicer.

1. Open the flush volume matrix in Flash Studio and dial the numbers down by hand. Start by halving them and print a test — guessing doesn't work here.
2. Enable flushing into the object or into infill so the plastic ends up inside the part instead of the tower.
3. Plan your color order. Light-to-dark transitions need far less purging than the reverse.
4. Keep paired materials close in temperature, or you'll have to push the flush volumes right back up.
5. Build your own filament profiles: Flash Studio ships no third-party presets, so flow and Pressure Advance need manual calibration too.

9. Purge waste drops inside the frame — and used to land in a fan

There's no waste bin in the box at all: cuttings fall to the floor of the printer on every filament change and during the flow calibration before each print. Leave them for a few prints and the plastic works its way into the vents. Worse, until July 2026 the drop point was such that some owners had purge waste landing straight in a fan.

1. Update to at least 1.9.4 (9 July 2026), which moved the purge drop point to the rear of the printer.
2. Print the official bin: Hanger.step and Poop Bin (Hanger Version).step are in the wiki guide, along with ready G-code — 3 h 19 min in PLA, 3 h 11 min in PETG.
3. Tape the hanger to the rear right of the frame with double-sided tape and hook the bin onto it.
4. Check clearance with the bed fully lowered. Owners have had the bed crush a home-brew bin into the floor of the printer during homing.
5. Line the inside with aluminum tape so hot plastic doesn't stick to the walls.
6. Empty the bin every time you pull a finished print. That's the official recommendation: waste sticks to the side wall and piles up above the rim.

10. The prime tower collapses mid-print

The tower lifts off the bed or delaminates, the nozzle knocks it over and drags it across the chamber along with the model. On a multicolor job that's the whole print gone — and four-color prints are rarely short.

The official cause list is long: failed leveling calibration and a wrong first-layer height, wrong bed temperature, a contaminated bed, tower delamination between two materials with very different viscosity, and the nozzle striking the tower because undried filament oozed onto it.

1. Dry both materials thoroughly. Oozing wet filament is the most common reason the nozzle catches the tower.
2. Wash the bed: grease and plastic residue kill adhesion on the tower first, because its footprint is small.
3. Level before the print rather than trusting a month-old mesh.
4. For mixed prints, set the bed temperature by the official guide: 60–65 °C for a PLA + PETG pairing.
5. Avoid pairing materials with very different viscosity where you can. If you must, split the towers per material so layers of different plastics don't stack on each other.

11. Clogs: soft TPU and incompatible material pairs

Two documented scenarios. First, TPU softer than standard: in Tom's Hardware testing a 40D filament clogged the extruder badly enough that the toolhead had to be disassembled, and the part never finished. Second, an incompatible pairing: a Creator 5 Pro owner ran ABS with PLA supports and got a clog at roughly the first layer.

One rule from the official filament guide deserves its own line: low-temperature plastics — PLA, PETG, PETG-CF, TPU, PLA-CF, PVA, BVOH — are strictly forbidden in a heated chamber. Above 45 °C chamber temperature they soften inside the extruder and hotend, and a clog becomes a matter of time. That applies to base Creator 5 owners who threw a home-made enclosure over the open frame too.

1. Dry TPU before printing and feed it straight from the dryer. Flashforge's own figure is to keep dry-box humidity below 15 %.
2. Slow down — reduced speed for flexible materials is a direct manufacturer recommendation.
3. Shorten the feed path: short PTFE tube, spool closer to the printer, larger nozzle diameter.
4. Never mix materials with non-overlapping temperature windows. PLA supports under ABS is a guaranteed clog.
5. For a PLA + PETG pairing: bed at 60–65 °C, raise the PLA nozzle temperature to 225–230 °C for support adhesion, and use a high-speed PETG whose working temperature sits closer to PLA.
6. If it's already clogged: needle from the toolkit, then a cold pull, then a full hotend swap. Push the cutter lever down, remove two screws, pull the hotend out downward and fit a new one.
7. After any hotend swap, run extruder offset calibration — otherwise you inherit problem 6 from this list.

12. Loading and unloading filament is entirely manual

The Creator 5 has no automatic feed whatsoever — a deliberate simplification to hit the price. There's no RFID either: filament type and color are assigned by hand in the interface. To load, you lift the head off its dock, squeeze the cutter lever (which also releases the extruder tension) and push the filament through with your fingers. Unloading is the same in reverse. Reviewers call it the most annoying part of ownership.

1. Cut the filament end square. An angled cut snags at the filament sensor — it's the first cause listed under guide-tube problems.
2. Feed the filament into the numbered port in the side panel and push it through to the tool.
3. Lift that tool off the dock, squeeze the cutter lever and feed the filament until it stops.
4. To unload, push the lever all the way down first so the cutter severs the filament, and only then pull it back out from the inlet side.
5. Soft TPU sometimes won't go in on the first try: detach the PTFE tube from the top of the extruder and feed by hand — exactly what the Notebookcheck reviewer did with TPU 95A.
6. Keep at least 50 mm between nozzle and bed while loading. That's an official requirement — a smaller gap causes clogs.

One more surprise: on load, the printer heats the nozzle for the last material used — 250 °C for PLA and TPU, 270 °C for PETG — and dumps a decent blob of plastic onto the floor of the frame. That's designed behavior rather than a fault, which is exactly why the waste bin from the previous section is worth printing before your first load.

13. VFA vertical banding on flat surfaces

Fine vertical lines on side walls. You'll never see them on a keychain, but on a large part with a big flat face they're obvious. One owner reported that after adjusting the belts per the manual and running resonance compensation, the banding only disappeared completely at 170 mm/s and above.

Flashforge attributes VFAs to micro-vibrations from mechanical resonance, belt tension and uneven stepper torque. Since 1.9.6 the printer runs an algorithm that compensates for torque ripple during motor rotation — treating the cause rather than masking the symptom.

1. Update to 1.9.6 or newer — without it the VFA compensation entry simply isn't in the menu.
2. Adjust XY belt tension per the official procedure.
3. Run Vibration Compensation.
4. Run VFA vertical stripe compensation, the fifth entry under Move & Calibrate → Calibrate.
5. If banding survives, raise your outer wall speed: owners report it clearing above 170 mm/s.
6. Check the X-axis linear bearing lubrication — dry bearings cause both rattle and banding. See the next section.

14. The printer arrives dry, with no lubrication

A sachet of grease ships in the box, but the machine leaves the factory unlubricated. Two owners tested it the same way — a finger run along the rails came back clean. One asked the seller directly and was told lubrication was done at the factory. It wasn't.

You can hear it straight away: on fast X-axis moves the balls inside the linear bearings rattle as though they're running dry. On a brand-new printer that isn't a failure, it's an unfinished assembly step you can close in five minutes.

1. Run a finger along the Y rods and the Z lead screws. A clean finger means there's no grease.
2. Apply the supplied lubricant to the X linear rail, the round Y rods and all three Z lead screws.
3. Do the X-axis linear bearings separately — they're the ones rattling on fast moves.
4. After that, follow the official maintenance schedule: the wiki has dedicated pages for cleaning and lubricating the Y rail, X shaft, XY and Z pulleys, Z linear bearings and Z lead screws.

15. Banging at high accelerations

On sharp direction changes the printer produces thuds you can hear from the next room. The spec sheet lists 55–65 dB at idle and under 55 dB in silent mode, but that spec isn't measured while the machine ramps to 30 000 mm/s² with 600 mm/s travels.

The physics are straightforward: a light 14 kg frame, a heavy toolhead, and a jerk value of 9 in the config against 8 on the far heavier Creality K2 Plus. Part of the noise was software, too — firmware 1.9.3 of 15 June 2026 lists "fixed abnormal noise under high-speed operation" as its own line item.

1. Update to 1.9.3 or newer.
2. Turn on silent mode — the spec puts it under 55 dB, and 1.9.6 optimized it further.
3. Lower jerk and acceleration in your slicer profile; the defaults assume a heavier machine.
4. Lubricate the rails — dry bearings add rattle on top of the thuds.
5. Put the printer on a solid worktop rather than a hollow cabinet, which acts as a resonator.

16. Squeaking and worn grooves on the spool holder

Third-party spools produce an odd noise as they turn, and grooves gradually wear into the plastic holder. The cause is sharp edges and protrusions inside some third-party spools, which rub the holder as the spool rotates. Flashforge gave this its own entry in the official troubleshooting section and even attached video.

1. Print two spacers from the part1.step file on the official wiki — any filament will do.
2. Fit one spacer on each side of the spool, mount it on the holder and print as usual.
3. If the spool turns stiffly, the problem may be clamping rather than edges. A stiff spool leads straight to a feeding timeout.

17. 5 GHz Wi-Fi drops within seconds

The printer joins a 5 GHz network and loses it almost immediately. One owner describes a connection that survives literally a couple of seconds before they have to reconnect from the screen. On 2.4 GHz, the same machine stays up.

1. Move the printer to 2.4 GHz. Both bands are supported, but the lower one is what holds in practice.
2. Strip special characters from the network name and password — that's an official cause of connection failure in Flashforge's FAQ.
3. Update the firmware. 1.7.8 fixed Flash Studio falsely showing offline right after connecting; 1.9.2 fixed it staying offline after a long network outage.
4. If you need guaranteed stability, run an Ethernet cable. LAN mode sends files fine, but the mobile app isn't available in it.
5. Don't panic if the network drops mid-print: a connection loss doesn't interrupt printing.

18. USB firmware updates refuse to install

The update aborts, or the printer doesn't see any files at all — just folders on screen. The answer isn't obvious: it wants a USB 2.0 stick. One owner spent a long time chasing this before digging out an ancient drive, which flashed on the first attempt.

1. Format the drive as FAT32. On any other file system print files simply don't appear — that's error E0019.
2. Use a USB 2.0 stick rather than a 3.0 one.
3. Don't power off the printer or drop the network during firmware download or installation — that's an explicit official warning.
4. Wait for the print screen to appear before pulling the drive, or you'll get E0028 "File copy error".
5. If it still won't take, firmware also arrives over the air: one owner received the 1.9.5 update over the air, with no USB stick involved.

19. The screen freezes, ignores touch or shows a mosaic

Three different faults with one symptom. Software: the screen hangs during filament loading or when tapped mid-print — both fixed in firmware 1.7.8 of 27 April 2026. Hardware: a mosaic pattern from a loose connector. And factory defects: one owner's printer arrived with a dead digitizer — the display lights up but ignores touch, then freezes after a print finishes, so the next job only goes through after a power cycle.

1. Update to 1.7.8 or newer, which closes both freeze scenarios.
2. For the mosaic, power off, remove the screws, reseat the display ribbon until it's fully home, and reassemble.
3. If the screen is white on boot but you hear the startup chime, the display or its cable needs replacing.
4. A dead digitizer out of the box only gets fixed by replacement — open a claim straight away.
5. Remember the pop-up: until you dismiss it on the printer itself, remote print starts won't work.

20. Flash Studio and OrcaSlicer can't see the printer

The slicer shows the printer offline or refuses the connection outright. An OrcaSlicer issue filed on 17 June 2026 and closed without a documented fix puts it plainly: "TCPConsole: Can't connect to [IP]:8899: Connection refused" — with Wi-Fi configured, LAN-only mode enabled and the host type set to Flashforge.

The printer's network layer is closed: Flashforge gives you no browser access by IP at all. There's a second trap in the vendor slicer itself — one owner found build 1.7.2 broke the connection entirely while going back to 1.7.11 restored it. Flash Studio's numbering isn't strictly ordered, so go by build date rather than version number.

1. Use Flash Studio rather than vanilla OrcaSlicer: only the vendor slicer pairing is officially supported.
2. If the connection died after a slicer update, roll back to the previous version.
3. Check that no unread pop-up is sitting on the printer's screen.
4. Don't count on automatic sync: filaments assigned on the printer show up on the device page, but you still pick them manually in the slicer.
5. The fallback always works — copy the file onto a FAT32 USB stick.

We covered general Orca-family settings in our OrcaSlicer guide — Flash Studio is built on the same engine, so nearly everything there transfers.

21. Errors E0116, E0117 and E0119 on arc-heavy models

The print dies with an exception in priming_handler or flush_handler, or a timing error asking you to copy the logs. It looks random, but the cause is specific.

Flashforge names two: an unstable extruder board connection, and models with a lot of curves. In the second case the slicer's Arc fitting turns smooth arcs into a dense stream of tiny segments, and the printer's modest processor can't keep up. The related E0017 "Command exceeds queue limit" is a straight buffer overflow from excessive speed.

1. Disable Arc fitting in the slicer and re-slice the model.
2. Reseat the extruder board ribbon and restart the printer.
3. For E0017, drop overall print speed to 50 % or reduce slicing resolution — that's the official fix.
4. If nothing helps, copy the logs to a USB stick and send them to support together with the model file. This error can't be diagnosed without the model.

Four more things you learn only after buying

• A 120 °C bed setting gives about 100 °C on the surface. That's not a bad unit, it's Flashforge's own FAQ figure: at a 120 °C setpoint the actual surface temperature is around 100 °C, and heating to 100 °C takes roughly 250 s. If material lifts, raise the bed 5–10 °C above the material's nominal figure and let it soak, rather than trusting the number on screen.
• Clearances are larger than they look. The official minimums are 10 mm on the left and rear, 200 mm on the right and 500 mm at the front. With four spools mounted, owners measured 52 cm wide, 60–61 cm deep and 71–72 cm tall. Without the spool holders the printer shrinks to roughly 44 × 41 cm, so moving filament to a separate dryer genuinely buys back desk space.
• Spare parts were missing at launch — they're stocked now. Reviews from spring and early summer 2026 complained that extruder motors, fans, heaters and even the nozzles were unavailable for the Creator 5, with only 0.4 mm listed. As of 16 August 2026 that no longer holds: the official store carries 15 Creator 5 Series line items and every one is in stock. The nozzle assembly comes in four diameters — 0.25 mm at $39.90, 0.4 mm and 0.6 mm at $35, 0.8 mm at $39.90. The extruder assembly is $79, the filament cutter $14.90, the PEI plate $29.90, the silicone sock $9.90, the nozzle blockers $19.90, the extruder cooling fan $49.90, the feed gear assembly $29.90, the camera module $29.90 and the touchscreen $49.90. On this point the two-month-old reviews are simply out of date — check the store, not them. What the store still doesn't sell is an enclosure kit for the base model.
• The base model cannot become a Pro. Flashforge's answer is a flat no: the Pro has a different structure, with an active chamber heater to 65 °C and adaptive air circulation. The shells look identical, but there's no fan behind the base model's vent grille and nowhere to mount one. If you need engineering materials regularly, buy the Pro up front.

Creator 5 error codes: what they mean and what to do

Flashforge keeps the full list in its official wiki, running from E0001 all the way to E0159. Below are the ones tied specifically to the toolchanger, the eddy-current leveling system and typical Creator 5 failures. T1–T4 codes repeat per tool, so they're grouped into ranges.

What the firmware fixed, in order

This table is more useful than it looks. It shows which problems are already closed by an update and which ones live in the hardware. If your printer shipped with an April build, half the issues in this article go away with a single update.
