Service Diagnostics; Entering Service Diagnostics Mode; Dip Switches - Xerox 7700DX - Phaser Color Laser Printer Service Manual

Service Diagnostics

Service diagnostics are to be executed by the service technician through the
front panel. The DIP switches should be set to Service Mode while performing
functions of the Service Diagnostics menu.

Entering Service Diagnostics Mode

1. To enter Diagnostics mode the printer must be turned Off.
2. Hold down the Back and Information keys simultaneously and turn the
printer back on.
3. Continue to hold the keys until the following message is displayed on the
front panel: "Service Diagnostics V3.60, Initializing", and then release.
4. Next, the front panel displays the Service Diagnostics Menu.
You can print a service Diagnostics menu map by highlighting "Print Service
Menu Map", using the arrow key and pressing OK.

Dip Switches

Four DIP switches allow you to reset the printer or place the printer in different
operating modes. You must set the switches before the printer is switched On
to enter the selected mode.
Note When performing the Registration Control Procedures
(Processes of the RegiCon Adjustment on page 4-127),
you must set the switches to Service Mode (refer to Rear
Panel on page 1-23). This avoids a problem with
RegiCon when the customer has the PostScript
startpage enabled.
Note The Service Menu functions are to be used only by Xerox
service personnel and authorized service providers. The
printer can be damaged by the improper use of the
built-in service tests.
In all the service tests,
The Back or Cancel button can be used to abort a test and return
you to the menu from where the test began.
The OK button either enters the next lower level menu or causes the
highlighted test to execute.
The Up and Down keys highlight test options or selection of an
appropriate entry while executing a test. If there is a numeric value
that must be entered these keys are used to adjust that value.
The Info button is used to post information or define a mnemonic.
Press the Info or OK button again to remove the text and restore the
menu.
