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
The fuser assembly hit a hardware or heat-control fault.
The printer could not complete fuser checks during startup.
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.
