Main code Sub code
26 10 AE original density setting
Used to set the original density. (Set value: 1 ∼ 9)
Default: 2 Set to 9 if the density is extremely low.
24 Binding margin forming direction setting
0: Left binding (Default)
1: Right binding
25 Duplex copy mode (even number originals) standard setting
The standard setting after auto clear time operation is normally single → single copy mode.
By performing this simulation and entering 1, the standard setting is changed to the duplex copy mode
(even number originals).
27 01 PPC communication trouble
30 01 Monitoring main unit paper sensor
Used to check the on/off state of paper sensor in the copier.
When the sensor turns on, the display reverses.
02 Monitoring paper cassette size
Used to check the on/off state of paper cassette size. When the switch turns on, the display reverses.
42 * DV life counter clear
Used to clear the copy quantity counter of the installed DV unit.
When the main code is entered and the START key is pressed, the staple check lamp is lighted for
confirmation. At that time, the DV life counter is cleared by entering 1
°
43 * Fusing temperature setting
Used to set the fusing temperature.
When this simulation is executed, the currently set fusing temperature is displayed. When 10 key is
pressed under this state, the number is displayed on the magnification ratio display, and the fusing
temperature corresponding to the number is displayed on the copy quantity display by 2 digits.
Display method of the copy quantity display
If the fusing temperature is in 2 digits, it is displayed normally. If it is over 3 digits, the upper 2 digits
are displayed after a long blank interval then the lower 2 digits are displayed after a short blank
interval.
44 01 Correction mode setting
[+ 1] Process control correction enable
[+ 2] Optical dirt correction enable
[+ 4] Drum layer wear correction enable
[+10] Toner control A correction valid
[+20] Toner control B correction valid
Note: When all are "Enable," set to 37.
02 Drum mark sensor sensitivity adjustment
For the drum mark sensor gain rank, [2] is selected.
The main motor rotates and the drum mark sensor sensing level is displayed on the multi-display
section. Adjust VR1 in the process unit to obtain [204±10].
03 Image density sensor sensitivity adjustment
For the image density sensor gain rank, [2] is selected.
The main motor rotates and the image density sensor sensing level is displayed on the multi-display
section. Adjust VR2 in the process unit to obtain [204±10].
When P lamp is OFF Temperature setting in single copy
When P lamp is ON Temperature setting in duplex copy
(3 digits or more):

The corrections, except for the process control correction mode, can be disabled in the normal
copy mode. When "0" is inputted, "1" (Process control correction) is enabled. (Automatic setting)
