Phaser 7700 Color Laser Printer Service Manual
If any RegiCon routine appears to run correctly, but does not return any
results:
1.
You did not wait 10 seconds after the display indicated “Ready to Print”
before re-booting the printer.
2.
“Netware” was not disabled.
3.
If the printer is running version 4.02 Postcript code and Netware is
enabled, RegiCon will not initialize properly (typicaly will result in an error
80 condition). Disable Netware before performing any RegiCon procedure
in diagnostics.
4.
The Hard Disk Drive has the MFGstartjob snippet in the sys.start file.
Download the usrstart_del.ps snippet to the printer. This snippet can be
found on the Xerox website:

ets.html
5.
The MOB Sensor could be malfunctioning.
Note
Remember to re-enable Netware after any RegiCon
procedures have completed and new NVRAM values
have been saved to the Hard Drive.
If you waited the required 10 seconds before re-booting and did not get any
results, verify that the MOB Sensor is operating correctly by running the ADC
Output check from the Adjustments/Calibration menu.
The test provides results that indicate if the ADC Sensor shutter is working
and if the Sensors are working and reading the ADC patches. It also has an
LD Illum warn =() and if a color (CMYK) is shown in the parentheses, the
Laser has probably failed.
Example of a Normal Result
Note
Values denoted with a * are examples of results and will
be different from printer to printer.
The ADC Output Check may need to be run several times to calibrate the
Sensor as close to the target value as possible. If the prints remain dark after
running the ADC Output Check and teh Fast Scan 8 tone prints do not look
similar, replace the Engine Control Board (page 7-207).
The first two screens indicate that the test ran without errors:
Result=0 Stop Status=0 ADC Sensor Fail=0 ADC Shutter Fail=0
LD Illum War=None ADC Patch Fail=None VBCR Warn=None VBias
Warn=None
The next four screens display values for each color. The target value is a set
value and the Ave and Ideal numbers are the readings for the Sensor and
may change.
