  • !Any 920 to 925 error remains after restart.
  • !The printer also shows flashing lights or repeated service faults during boot.
If the printer still starts normally: Try one careful restart or the first official recovery step, then stop if the same error comes back straight away.

What to check first

Step-by-step checks

  1. 1

    Safe first step

    Power the printer off and leave it off for at least 10 seconds before restarting.

    Start with the official recovery step before moving on to parts or deeper servicing.

  2. 2

    Safe first step

    If the message clears, test the printer with one short job before resuming heavier use.

  3. 3

    Safe first step

    If the message returns, stop and record the full 920.xx style code.

Background

What this message usually means

Lexmark uses 920 through 925 for service fuser errors. These are hardware-side faults tied to the fuser section rather than routine jams or toner prompts, so the safest first step is a cold restart and then escalation if the service error remains.

Diagnosis

Likely causes

Most common

The fuser assembly hit a hardware or heat-control fault.

Common

The printer could not complete fuser checks during startup.

Possible

A service-level component issue remains after a previous restart.

Service

When service or replacement is more likely

  • -Treat fuser service errors as hardware faults first, not as paper or toner issues.
  • -Exact panel behavior can vary by Lexmark family, but the escalation posture stays the same.

Source notes

Lexmark’s official service-fuser article groups 920 through 925 as fuser hardware errors and recommends a restart before service escalation.

Built around official Lexmark office-printer guidance. Code meanings are family-level and can still vary by exact model, installed finisher options, and firmware generation.

Printer error codes can vary a little by firmware, region, and exact model variant. Use this guide as a family-level starting point and stop if the next step would require disassembly or service-mode changes.

Known family variants: MS310, MS410, MS510, MS610, MX310, MX410, MX510, MX610
