Lexmark error code 31.xx

Before you try the solution

1. 1. Copy the complete message exactly as shown, including any letters, spaces, or punctuation around 31.xx.
2. 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
3. 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.

Manufacturer-documented solution

If the error is still there

1. 1Return to the screen or job that produced the message and check whether the code has cleared.
2. 2If 31.xx returns, do not repeat a risky procedure. Record when it appears and check the documentation for the exact model.
3. 3Because this message involves opening the printer, service risk, or possible damage, stop and contact Lexmark support or a qualified printer technician if it persists.

Other Lexmark error codes

• 32.xx"Replace unsupported" — the printer recognises the supply but rejects it as not supported by this model. The second pair names the supply: 32.40-32.43 a colour cartridge, 32.60 the black imaging unit, 32.64 the colour imaging kit, and a 32.xy variant the fuser. This is a different fault from 31.xx (missing or unresponsive) and from 42.xx (right supply, wrong region).
• 33.xx"Non-Lexmark supply, see User's Guide" — the printer has detected a cartridge, imaging unit, or imaging kit that it does not identify as Lexmark-made. 33.40-33.43 is a colour cartridge, 33.60 the black imaging unit, 33.64 the colour imaging kit. It is a notice about the supply's origin, not a report of a hardware fault.
• 37.xInsufficient printer memory. 37.1 means there is not enough memory to collate the job, and 37.3 means some held jobs were deleted to make room. The related 39.1 "complex page" warns that a page was too complex to render fully, so some data may not have printed. All three are memory-pressure notices, not hardware faults.
• 200.xxIndicates the printer registered one or more sheets as jammed under the toner cartridge, not specifically 'at the front of the printer.' If no physical jam is found despite repeated occurrences, a jam sensor may be malfunctioning and require service.
• 42.xx"Replace cartridge, printer region mismatch" — the cartridge is genuine and otherwise correct, but it was manufactured for a different geographic region than the printer. Lexmark region-codes printers and cartridges to each other, so a cartridge bought in another region will be refused even when it physically fits. The fix is a cartridge made for your printer's region.
• 55.1"Error reading USB drive. Remove USB." The printer cannot read the USB flash drive plugged into its front port. The companion code 55.2 is the same fault for a USB hub, which Lexmark asks you to remove. Neither affects normal network or cable printing.
