(4) Kinds of error (RADF single mode only)
Kinds of JAM, error
Not-reaching/remaining JAM in
the paper feed section
Not-reaching/remaining JAM in
the paper exit section
Paper feed motor lock error
Resist/timing sensor
adjustment error (when power
is supplied)
Paper exit sensor adjustment
error (when power is supplied)
A JAM/motor lock error can be canceled by opening/closing the ADF
after jam recovery process or by applying the power again.

There are following items of adjustments by the simulations of the
machine.
Name Adjustment items
Lead edge The lead edge and the
position image lead edge are
adjustment adjusted in the range of
+5mm to +5mm.
(Front and back surface
of a document)
Magnification The magnification ration
ratio is corrected. (–4.9% to
adjustment +4.9%)(Front and back
surface of a document)
Resist No. 1 resist (front surface
quantity of document) loop
adjustment quantity adjustment
(0.1mm ~ 9.9mm)
No. 2 resist (front surface
of document) loop
quantity adjustment
(0.1mm ~ 6.9mm)
Image loss The output timing of data
adjustment enable signal (DEN) is
adjusted and data write
from the image lead edge
to the set quantity is cut.
(0 ~ 10mm)
Center shift
adjustment
Reflection Automatic initialization of
type sensor the post-separation
adjustment sensor, the read sensor,
and the SB sensor is
performed.

Image distortion adjustment procedure
Adjustment of hinge base dimension T of hinge ass'y R
(1) Loosen the RSPF fixing screw.
(2) Loosen the nut and turn the distortion adjustment screw to adjust
dimension T.
(3) Tighten two SPF fixing screws to fix the hinge base.
(4) Tighten the nut with the distortion adjustment screw fixed.
(Adjustment 1) Turn the distortion adjustment screw in direction of A.
— Dimension T is increased.
(Adjustment 2) Turn the distortion adjustment screw in direction of B.
— Dimension T is decreased.
