51 02 Resist roller adjustments
Used to set the on timing of the paper feed roller (rate of buckle in the paper caused by the resist
roller). When the test command is executed, the manual feed mode is automatically established.
Change the manual feed mode resisting rate, cassette paper feed resist rate, and ADU paper feed
resist rate independantly.
Press the C → =↵ → 0/◊ → =↵ → 5 → 1 → PSW → 2 → PSW → keys. The manual
feed lamp turns on → 1 Enter number → press the cassette key (main unit bottom cassette and
pause lamp turn on) → 2 enter number → press the cassette key (main unit bottom cassette lamp
turns on) → 3 enter number → press the cassette key.
1: Manual feed paper resist rate adjustment (MULTI TRAY)
2: Cassette paper resist rate adjustment (TRAY)
3: ADU paper resist rate adjustment (ADU)
RESIST AMOUNT ADJUSTMENT
MULTI TRAY : 40

05 Frame delete rate adjustment (copy moving direction only)
Used to set the frame delete rate.

52 01 ADU alignment plate adjust value setup
Used to adjust the home position of the ADU alignment plate.
When the test command is executed, the READY lamp turns on. Enter a new value as the previously
set value came displayed, and press the PRINT switch to stored it in memory. It is adjustable from 1
to 99. The default is 7.
Setting a smaller value increases the width of the alignment plate and vice versa.
°
02 ADU rear plate adjust value setup
Used to adjust the home position of the ADU rear plate.
When the test command is executed, the READY lamp turns on. Enter a new value as the previously
set value came displayed, and press the PRINT switch to stored it in the memory. It is adjustable
from 0 to 99. The default is 0. Setting a smaller value increases the width of the rear plate and vice
versa.
03 ADU drive clutch off time setup
Can be set to any number between 0 and 99 (Standard: 18).
0 = 19ms 1 = 1ms ⋅⋅⋅⋅⋅⋅ 18 = 18ms ⋅⋅⋅⋅⋅⋅ 99 = 99ms
Setting a smaller value shortens the ADU clutch off timings and decreases the enforced curling rate of
paper.
°
53 01 RADF and ADF stop position adjustment value (normal paper, single copy) setting
Used to adjust the RADF stop position in single copy with normal paper.
When this simulation is executed, the ready lamp lights up and the currently set adjustment value is
displayed. Enter the new adjustment value and press the PRINT switch to store it in the memory. The
adjustment value should be in the range of 0 to 15.
°
02 RADF stop position adjustment value (normal paper, duplex copy) setting
Used to adjust the RADF stop position in duplex copy with normal paper.
When this simulation is executed, the ready lamp lights up and the currently set adjustment value is
displayed. Enter the new adjustment value and press the PRINT switch to store it in the memory. The
adjustment value should be in the range of 0 to 15.
°
03 RADF and ADF stop position adjustment value (thin paper, single copy) setting
Used to adjust the RADF stop position in single copy with thin paper.
When this simulation is executed, the ready lamp lights up and the currently set adjustment value is
displayed. Enter the new adjustment value and press the PRINT switch to store it in the memory. The
adjustment value should be in the range of 0 to 15.
°
04 RADF and ADF stop position adjustment value (thin paper, duplex copy) setting
Used to adjust the RADF stop position in duplex copy with thin paper.
When this simulation is executed, the ready lamp lights up and the currently set adjustment value is
displayed. Enter the new adjustment value and press the PRINT switch to store it in the memory. The
adjustment value should be in the range of 0 to 15.
°
05 RADF and ADF resist sensor adjustment
Used to adjust the RADF resist sensor. (In the case of ADF, the resist sensor and the paper pass
width sensor are adjusted.)
When this simulation is executed, the RADF resist sensor is adjusted and the adjustment value is
displayed.
TRAY : 45
ADU : 50
When the test command is executed, the READY lamp turns on, and the figure previously stored is
displayed on the copy number window.
Now, it becomes ready to accept a number between 1 and 19 on the keypad. When the PRINT
switch is pressed after the entry, the number is stored in the memory and the READY lamp turns
off. A single rate deletes the frame of about 1.0mm. The standard value has been set to "6."
