DENS-C-H Dspl of ATR ctrl C-clr TD ratio history
Lv.2 Details To display the latest 8 C-toner density log data (TD ratio) detected by
the ATR Sensor at ATR control.
Sharp change in values may indicate ATR Sensor disconnection/
failure, whereas gradual change in values may indicate failure in
toner supply system.
Use case When checking toner density in the Developing Assembly at low
density or fogging deterioration
Display/adj/set range 0 to 255
Appropriate target value 20 to 230
DS-S-Y-H Dspl of Y-color patch image density log
Lv.2 Details To display the latest 8 Y-patch image density log data.
It is the reference for judging the cause at E020 occurrence, etc.
Sharp change in values may indicate the failure in Patch Sensor,
Shutter or laser, whereas gradual change may indicate failure in
toner supply system.
This is particularly caused by Patch Sensor.
Use case When analyzing the cause of E020
Display/adj/set range 0 to 1023
Appropriate target value 200 to 900
DS-S-M-H Dspl of M-color patch image density log
Lv.2 Details To display the latest 8 M-patch image density log data.
It is the reference for judging the cause at E020 occurrence, etc.
Sharp change in values may indicate the failure in Patch Sensor,
Shutter or laser, whereas gradual change may indicate failure in
toner supply system.
This is particularly caused by Patch Sensor.
Use case When analyzing the cause of E020
Display/adj/set range 0 to 1023
Appropriate target value 200 to 900
DS-S-C-H Dspl of C-color patch image density log
Lv.2 Details To display the latest 8 C-patch image density log data.
It is the reference for judging the cause at E020 occurrence, etc.
Sharp change in values may indicate the failure in Patch Sensor,
Shutter or laser, whereas gradual change may indicate failure in
toner supply system.
This is particularly caused by Patch Sensor.
Use case When analyzing the cause of E020
Display/adj/set range 0 to 1023

DS-S-K-H Dspl Bk-clr patch image density history
Lv.2 Details To display the latest 8 Bk-patch image density log data.
It is the reference for judging the cause at E020 occurrence, etc.
Sharp change in values may indicate the failure in Patch Sensor,
Shutter or laser, whereas gradual change may indicate failure in
toner supply system.
This is particularly caused by Patch Sensor.
Use case When analyzing the cause of E020
Display/adj/set range 0 to 1023
Appropriate target value 200 to 900
P-LED-DA Dspl of Patch Sensor LED light intensity
Lv.2 Details To display the Patch Sensor LED light intensity.
The soiled Sensor window or soiled ITB (ITB cleaning failure) is
suspected if the background light intensity (P-wave) is too low even
with sufficient LED light intensity and PT-LPADJ execution will not
correct the problem.
Use case When checking the Patch Sensor
