What usually causes it
- Support code 2803 means an original in the automatic document feeder is too long or has jammed. The fault concerns originals being scanned, not printer paper from a cassette.
- The exact reviewed condition is: Document is too long or jammed in the automatic document feeder.
- Remove the document through the normal ADF jam path, check for folded/torn pages, square the originals, and make sure the document size is within the feeder’s supported range.
What to try
Check the condition this code actually names
Remove the document through the normal ADF jam path, check for folded/torn pages, square the originals, and make sure the document size is within the feeder’s supported range.
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
Test with a few clean normal-size originals before retrying the full document. If the scanner glass works while the ADF repeats 2803, the feeder path is isolated.
After each corrective action
Retry the original operation that produced 2803. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If 2803 returns, note whether the first page enters and where it stops, plus the original size/condition.
When service may be needed
Do not force long documents through the feeder or dismantle its sensors. Persistent jams with supported originals require 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.
