DF-WLVL1/2
Use it to execute ADF white level adjustment (platen board scan/stream reading scan)
Procedure
1) Place a sheet of paper (of the type most frequently used by the user) on the platen board glass, and execute the following:
COPIER>FUNCTION>CCD>DF-WLVL1.
The white level for book mode is read (checking the degree of transmission of the glass for book mode).
2) Place a sheet of paper often used by the user in the DF, and execute the following: COPIER>FUNCTION>CCD>DF-WLVL2.
The white level for DF mode (stream reading) is read (checking the degree of transmission of glass for stream reading; reading both
sides of the chart).
face: computes DFTAR-R/G/B
back: computes DFTAR2-R/G/B
Caution:
Be sure to execute both of the foregoing 2 items at the same time.
1
LUT-ADJ
start-ups the reading sequence for CCD seam correction data (gray plate scanning) [not operating in this machine]
1
DF-LNR
Start of calculation of gain offset for front/back matching from DF composite chart reading data (No. 2 and No. 10)
By executing this mode after setting the reading data of No. 2 and No. 10 of DF composite chart to perform matching of difference
in front/back density to "ADJUST>CCD>DFCH_XX", linearity characteristics are calculated and a setting value is determined.
1
MTF-CLC
Calculate the MTF filter count which is actually set to ASIC based on the MTF value.
Calculate the MTF filter count which is actually set to ASIC based on the MTF value specified for each CCD/CIS in
COPIER>ADJUST>CCD>MTF-M1 to 3, MTF-S1.

LUT-ADJ2
start-ups the reading sequence for CCD seam correction data 2 (DS chart)

POWER
Use it to turn on the laser for laser power adjustment.
Procedure
1) Select the item to highlight, and press the OK key.
2) See that the laser goes on.
3) See that the laser goes off in about 30 sec. (To turn it off in the middle, press the Stop key.)

COPIER > FUNCTION > DPC
Sub-item
Description
Level
DPC
Use it to force the execution of potential control.
The machine is designed so that it will not perform potential control at power-on (recovery mode) if the temperature of the fixing
assembly is 70 deg C or higher. If you have replaced the photosensitive drum or the laser unit, or if you have changed the drum
potential setting, be sure to execute this mode item.
Procedure
1) Select the item, and type in '1'; then, press the OK key.
2) Turn off and then on the main power switch.
3) See that the machine executes potential control and stops it automatically.
1
OFST
Use it to adjust the offset value of the potential sensor.
This mode item is part of the series of procedures you have to perform when you have replaced the potential sensor unit. Be sure
never to execute it on its own.
Procedure
1) Select the item to highlight, and press the OK key.
2) See that the machine executes offset adjustment and stops it automatically.
