4500-E220/E321/E323 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. 3-40 Service Manual
