Xerox 077-900 error code
Paper jam (paper left in the path)
Xerox 077-900 usually indicates a paper jam: a sensor detects paper in the paper path, typically because a sheet or scrap has been left inside. The 077-9xx family relates to paper jams.
What does this error mean?
If the code appears even when the printer seems empty, a small piece of paper has almost certainly been left near a sensor. It is worth checking all doors and the duplex path as well.
What can you safely try?
- 01Open the doors and covers and carefully remove all jammed paper from the paper path, including small scraps. The area around the fuser may be hot; wait a few minutes there.
- 02Also check the duplex (two-sided printing) path and the area behind the trays: small scraps often hide there.
- 03Switch the printer off at the main power switch, wait a few minutes, then switch it back on. Some temporary faults clear this way.
When should you call a technician?
If you cannot find any paper and the code remains, call a technician: a sensor may be stuck or faulty.
Do you rent out or manage printers?
If you manage the printer at a customer’s site, you can record the fault on site in PrinterMS using QR issue reporting, and any parts used are automatically added to its service history. See printer fleet management.
