What usually causes it
- 12-100 is a finisher jam on the Phaser 4600/4620/4622 platform. Xerox’s public path includes the finisher and adjacent fuser/output area, so the location matters more than a generic tray check.
- The exact reviewed condition is: Finisher jam message; Xerox gives specific finisher/fuser-area jam clearing, reseating, restart, and retry guidance.
- Let hot areas cool as instructed, clear accessible paper from the documented finisher/fuser-output path, reseat the finisher if the user procedure calls for it, and close all covers.
What to try
Check the condition this code actually names
Let hot areas cool as instructed, clear accessible paper from the documented finisher/fuser-output path, reseat the finisher if the user procedure calls for it, and close all covers.
Keep the test focused
Change only the setting, supply, paper path, or component named above. Leave unrelated network, driver, and service settings alone so the retest tells you something useful.
Run a controlled confirmation test
Restart and print a short plain job before retrying the same finishing operation that produced 12-100.
After each corrective action
Retry the original operation that produced 12-100. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If the code comes back, note whether plain output succeeds and whether the sheet actually enters the finisher. That pattern is more useful than repeated power cycles.
When service may be needed
Do not touch hot fuser surfaces or dismantle the finisher. Persistent 12-100 after accessible jam clearance belongs with Xerox service.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
