CHAPTER 4 SERVICE MODE
Level 3
D-SGNL-Y
Use it to adjust the signal value (during
D-SGNL-M
initialization) for the toner concentration sensor of
D-SGNL-C
each color in relation to light reflected by the
D-SGNL-K
photosensitive drum.
D-SGNL-4
Use it to adjust the signal value (during
(Note 1)
initialization) for the toner concentration sensor of
all colors in relation to light reflected by the
photosensitive drum.
P-REF-Y
Use it to adjust the toner concentration reference
P-REF-M
signal value for each color on the photosensitive
P-REF-C
drum during INIT for ATR control.
P-REF-K
(Note 1)
P-SGNL-Y
Use it to adjust the toner concentration reference
P-SGNL-M
signal value for each color on the photosensitive
P-SGNL-C
drum during INIT for ATR control.
P-SGNL-K
(Note 1)
SIGG-K
Use it to adjust the gain for the Bk toner
(Note 1)
concentration reference signal during ATR control.
SIGG-P-M
correction of the patch gain for ATR control when
SIGG-P-C
INIT-x (mono INIT) is executed
SIGG-P-Y
SIGG-P-K
(Note 1)
RGAN-P-M
correction of the patch gain for toner density control
RGAN-P-C
when INIT-x (mono INIT) is executed
RGAN-P-Y
RGAN-P-K
(Note 1)
Note 1: Execute this mode upon replacement of a CPU PCB or initialization of the RAM. The settings
will be returned to standard settings, requiring you to enter the appropriate settings. Be sure to
record any new settings on the service label.
