- Restart the printer and computer.
- Test another document or application.

Check the result
After each major change, print a small test page or retry the original task. Stop repeating cleaning cycles or resets when the result does not improve.
When to stop troubleshooting
Disconnect power and contact a qualified repair professional if the printer sparks, smells burnt, overheats, has liquid damage, a damaged power cable, grinding mechanical noise, or requires major disassembly.
