What usually causes it
- Tray 3 was opened or not fully seated while the printer was feeding paper.
- Tray configuration can be wrong after an option or envelope-tray change.
- An obstruction can keep the tray from closing completely.
What to try
Close Tray 3 completely
Push the tray in without forcing it and make sure nothing blocks the rails.
Check the loaded paper and tray configuration
Confirm the machine's Tray 3 settings match the installed tray/media.
Check an installed envelope tray
If one is present, verify Xerox's required configuration for that option.
Retry the original job
Once the tray is recognized as closed, resend the same print job.
After each corrective action
Retry the same operation that produced 73-500-00. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If the machine still reports the tray open when it is fully seated, stop forcing the tray and use Xerox support for the tray/sensor mechanism.
When service may be needed
Xerox hardware procedures vary by family. Stay with user-accessible paper/supply actions described for the reviewed models; if the fault returns after those checks, use the exact code and model when contacting support.

If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
