Using Safe Mode

Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue
offering as much functionality as possible despite known issues.
Warning—Potential Damage: Safe Mode is intended as a short-term workaround and should be used
only in the case of a non-critical error when a print job must be completed before service can be
arranged to repair the printer. The printer must be returned to standard operating mode before
diagnostics can be run or full-function printing can continue.
You can enter Safe Mode in one of the following ways:

Enable Safe Mode from the Configuration menu, and then POR the printer.

Press the Stop and Back keys, and then POR the printer.
Return the printer to standard operating mode to service the printer and return to full-function printing.
