Printer diagnostics mode
The printer diagnostics mode is for service use only. Its manipulation
is the same as the configuration mode. The following functions can
be performed in the diagnostics mode. See
“Configuration menu
group or diagnostic menu group” on page 3-36 for more
information.
1. Print diagnostic instructions and menu settings by pressing and
holding Continue until the lights cycle.
We recommend this sheet be run and checked anytime
diagnostics mode is entered. It provides instructions in the
manipulation of the menu.
2. Set edge–to–edge printing on/off.
– Off is the default and normal setting which allows the printer
graphics and printing engine to set the margins accordingly.
– When edge–to–edge is set on, the printer graphic and
printing engine shift all four margins to the physical edges of
the paper.
3. Print the print quality pages.
– These are the same pages that are run in the configuration
mode.
Note: The toner cartridge lockout function is disabled in this
mode.
– In the configuration mode, the lockout function is enabled
which means the pages cannot be printed unless the toner
cartridge has a machine class ID that matches the machine
class ID held in NVRAM on the operator panel card.
4. Print simplex from Tray 1, or Tray 2 (if installed). This sheet runs
continuously until Cancel is pressed. It can be used for skew or
printhead adjustments.
5. ‘Defaults=’ allows the printer to be set for U.S. or non–U.S. after
the controller card has been replaced.
6. Configuration ID allows the printer to have the ID set to match
the label after the controller card has been replaced.
