Cold reset
A cold reset unlocks menus that have been locked and resets control panel variables. However, it
does not clear the values in the SERVICE menu (such as the serial number and page counts).
To perform a cold reset
WARNING! Performing a cold reset erases all of the EIO card information.
- Turn the printer on.
- As the printer performs its power-on sequence, press and hold until all three lights on the control panel are lit.
- When SELECT LANGUAGE displays on the control panel, press [UP BUTTON] until COLD RESET displays on the control panel.
- Press [SELECT BUTTON]. The printer performs a cold reset and then continues its power-on sequence.
CAUTION Initializing NVRAM resets the serial number, the event log, the page counts, thecalibration settings, and the EIO card.
Use the SERVICE menu to restore the serial number and page counts. You also need to reconfigure any computers that print to this printer to recognize the printer. Initialize NVRAM only when absolutely necessary. In most situations, use a cold reset to reset printer variables but still retain the needed values in the SERVICE menu.
Before initializing NVRAM, print a configuration page and a supplies status page to gather the following information:
● Total page count and color page count
● Serial number
