Replacing The Eeprom - Ricoh M099 Service Training

After you replace the EEPROM, do the procedure
in the service manual.
The procedures for the MF models and printer
models are the same.
Slide 82
Serial Number:
You must ask your supervisor how to input this number.
LSU Adjustment:
Input the values from the sheet that comes with the laser optics housing
unit.
What does Transfer Belt Adjust do?
The new transfer belt may not be exactly the same length as the old one.
With this SP mode, the machine calibrates the motor speed for the new belt
(the speed is checked with a TM sensor pattern).
Fuser SC Detect:
This is normally OFF.
If you turn this ON, the machine will issue SC559 and stop working if three
consecutive paper jams occur in the fusing unit. Then, the technician must
visit the machine and reset the SC code and check the fusing unit.
If a sheet of paper feeds correctly, the counter is cleared – the SC only
appears if there are three consecutive jams on three successive sheets.
nd
2 Transfer Front/Back:
Normally all settings are 0.
You may need to change the settings in unusual environmental conditions,
for example if the humidity is low.
Color Registration
Performs the MUSIC adjustment
Check that MUSIC was done successfully.
