Change the setting of "COPIER > FUNCTION > INSTALL > AINR-OFF" from 0 to 1.
Caution :
Front left cover of main unit shall be opened whenever the above service mode is
executed.
MEMO :
The flag will be automatically restored to "0" after TONER-S completion.
4) Close the front left cover and front right cover.
5) After you close the front cover, wait for 5 seconds (or more) and perform the
following.
Caution :
If 5 seconds (or more) are not passed, the toner is not replenished.
6) Execute toner supply with a service mode.
(Toner supply: COPIER>FUNCTION>INSTALL>TONER-S)
7) Patch sensor light intensity correction/background detection, potential control,
D-max control Get in Service Mode to select the following:
(COPIER > FUNCTION > MISC-P > INTR-EX (LEVEL 2))
8) Execute cleaning of charging wire with a service mode.
(Cleaning of all charging wires: COPIER>FUNCTION>CLEANINNG>WIRE-CLN)
9) Execute setting of development contrast and charging voltage with a service mode.
(Execution of voltage control: COPIER>FUNCTION>MISC-P>INTER-EX)
10) Perform a power-cycle of main power (OFF/ON)
Title Photo-Sensitive Drum Unit
Explaination 1) Execute offset-adjustment of potential sensor for photosensitive drum with a service
mode.
(Potential sensor offset adjustment : COPIER > FUNCTION > DPC > OFST)
2) Execute setting of development contrast and charging voltage with a service mode.
(Execution of voltage control : COPIER > FUNCTION > MISC-P > INTER-EX)
3) Perform a power-cycle of main power (OFF / ON)
Title ITB
Explaination 1) ITB position shall be adjusted with a service mode whenever ITB pressure is
released.
(ITB positioning adjustment : COPIER > FUNCTION > INSTALL > INIT-ITB)

Title Skew Detection Sensor
Explaination 1) Execute light intensity auto adjustment in service mode.
(Level 2) COPIER > FUNCTION > SENS-ADJ > OP-SENS (auto adjustment of the
Scanner Sensor)
2) Execute skew adjustment.
2-1) Using a loupe (CK-0056), measure the margins L1 and L2 at the right edge of
a test print in increments of 0.05mm.
2-2) Obtain the skew adjustment value R from the following formula.
R = ((L2 - L1) / Lx) x 15200 (Round off the value to the nearest whole number.)
If the absolute value of the skew adjustment value R is 0.2 or larger
(R </= -0.2, 0.2 </= R), perform step 3.
2-3) Enter the skew adjustment value R in the following service mode.
(Level 1) COPIER > ADJUST > FEED-ADJ > REG-SKEW
Adjustment range: -500 to 500
Unit: 0.01mm
