Troubleshooting for the "Watchdog" error



When a Watchdog Error appears on the printer display, it is generally the result of an error message on the printer that causes a communication error between the printer and the scanner. This communication error will cause the scanner display to go dark and the yellow LED light beside it to flash.




Step Action
1 Power off the printer.
2 Press and hold the Menu button.
3 Power on the printer again.
Does the printer have an error code on the display panel?

Yes: Enter the specific error code in the problem search field on the previous page, and then follow the directions for resolving the specific error messages.
No: Power the printer off and back on again. If the problem persists, continue on to Contacting Lexmark below.
