Safety note: Turn off and unplug the printer before reaching into internal paper paths. Allow laser printers to cool. Do not use sharp tools or force covers and components.
Step-by-step checks
- Turn off and unplug the printer. Allow laser printers to cool.
- Remove loose paper from input and output trays.
- Open the access door identified by the printer display or manual.
- Pull jammed paper slowly in the normal paper-path direction.
- Check for torn scraps near rollers, the duplex unit, and rear access door.
- Reload flat, supported paper without overfilling the tray.
- Reconnect power and print a test page.
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.
