Used to adjust contact pressure between paper and the main body resist roller
or the SPF resist roller. (Amount of paper buckle at the resist roller)
Change the set value when the shift between the paper and the image varies.
(Operation/procedure)
When the simulation key operation is performed, the currently set value is
displayed on the COPIES SELECTED display.
Enter the set value with the numeral key and press the print button, and the
entered set value will be stored in the main PWB RAM.
The standard set value is 25. (Main body) 25 (SPF)
Tray paper feed mode:
Tray (upper) paper feed lamp ON
Manual paper feed mode: Manual paper feed lamp ON
SPF mode:
Upper and lower cassette paper feed lamps ON
The set value corresponds to the time interval between when the paper detec-
tor (PPD/SPPD) in front of the main body resist roller detects paper and when
the transport roller (TRC/SPFC) turns off.
The greater this time interval is, the greater the contact pressure between the
paper and the resist roller is.
@
The time interval can be set. The
greater the time interval is, the
greater the contact pressure be-
tween the paper and the resist
roller is. If the contact pressure is
too great, a paper jam may occur.
If the contact pressure is too
small, variations of image position
for the copy paper becomes
greater. This must be adjusted ac-
cording to the paper quality.

Used to adjust the copy magnification ratio in zoom copy.
The lens shift amount in zoom copy is changed to provide suitable magnifica-
tion ratio.
There is a slight variation in each lens focal distance. If the lenses are shifted
in a same amount in zoom copy, suitable magnification ratio may not be
obtained. To correct this, therefore, each lens is shifted according to its focal
distance.
The lens must be shifted in accordance with its focal distance in zoom copy,

(Operation/Procedure)
When the simulation key operation is performed, the currently set lens number
is displayed.
Enter the lens number with the ready lamp ON and press the print button, and
the entered number will be stored in the main PWB RAM. The lens number is
in proportion to the lens focal distance.

Used to adjust the copy paper lead edge void and the rear edge void amount.
(Operation/procedure)
When the simulation key operation is performed, warming-up operation is
performed. After completion of warming up, the currently set void amount is
displayed on the COPIES MADE display.
Use the tray select key to select between the lead edge void amount adjust-
ment and the rear edge void amount adjustment mode. The upper tray lamp
will change as shown in the table below.

The standard set value is 50. The void area increases 0.123mm for an in-
crease of the set value by 1.
