SHARP DTE126 Technical Report

Date: Jan. 24, 1994

DUPLICATOR: SD-2060

No. : DTE-126

TROUBLE SHOOTING ORIGINAL PAPER JAMS
IN THE OPTICAL AREA OF THE MACHINE.

1.Model name: SD-2060

2.General: When using the RADF, and especially when using thin original paper, the original paper

sometimes gets caught between the original stopper and the table glass. This problem
is generally caused by double feeding or by unevenness of the leading edge of the
original. The space between the table glass and the original stopper has been
narrowed, preventing this problem from occurring.

3.Cause: To prevent cams of the original paper in the optical area of the machine.

4.Description: The stopper bearing has been changed and a stopper adjustment plate has been

added. In carrying this out, the space between the copy table glass and the original
stopper has be decreased from the previous 0.3 ~ 0.5 mm to 0.08 ~ 0.1 mm, effectively
preventing the front edge of the original paper from becoming caught between the table
glass and the original stopper.
Note: Adjustment of the space between the table glass and the original spacer should

always be carried out (adjustment procedure is set forth under the section, “Field
action”, described below.)

➃ Attach the changed stopper bearing and the stopper adjustment plate.

As shown in the illustration below, attach the stopper adjustment plate and the stopper
bearing on the front frame side. Next, the stopper adjustment plate and the stopper
bearing on the rear frame side should be attached while the original stopper is in the
attached position. Attach the rear frame stopper adjustment plate and the stopper
bearing to the attached front frame bearing, and after lifting the upper cabinet (parts
guide 1 - 19) it should be pushed into position.
