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. See
“Safe Mode print behavior” on page 54 .
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:
•
Enter Safe Mode from the Configuration menu, and then POR the printer. See “Safe Mode” on page 344 .
•
For 2.4” display models, press the Stop and Back keys, and then POR the printer.
•
For 4.3” and 7” display touchscreen models, press the 6 and 7 keys, and then POR the printer.
•
For LED models, you must contact the next level of technical support for assistance.
Return the printer to standard operating mode to service the printer and return to full
‑
function printing.
