Blank copies, no error or alarms, makes blank copies?
I had a paper jam. I cleared it. After clearing the paper jam, the copier only prints out blank pages. I have even changed ink.

Subject:
Prevention of blank image (modifying the shape of the laser shutter and applying grease to the laser shutter arm)
Detail:
<Symptom>
Since the laser shutter [1] is not opened when the toner cartridge is inserted into the machine, a blank image is output in
some cases.
[1] Laser shutter
[2] Laser shutter arm
<Cause>
When the toner cartridge is inserted, the laser shutter arm [2] pushes down on the laser shutter [1]. In case that the arm has
a scratch on its sliding surface, however, it is caught in the area [3] where the arm comes into contact with the shutter,
preventing the shutter from being opened.

<Factory measures>
a. Modifying the shape of the laser shutter
Modify the shape of the laser shutter so as to prevent the shutter from being caught when the laser shutter arm pushes it
(A turnback is added to the edge of the area that contacts the laser shutter arm).
P-3 Laser shutter [A] Old type
[B] New type
b. Applying grease to the laser shutter arm
To decrease the sliding resistance of the contacting surface (P-2 [3]) of the laser shutter arm and laser shutter, apply grease
to the laser shutter arm.

c. Changing the shape of the laser shutter arm and applying grease to it.
To decrease the sliding resistance of the contacting surface of the laser shutter arm and laser shutter, change the shape of
the laser shutter arm. Additionally, apply grease to the arm.

d. Discontinuing application of grease to the laser shutter arm.
It was confirmed that the new shape of the laser shutter and laser shutter arm do not need lubrication by grease for normal
operation. From this, application of grease is discontinued.
Service Work:
When the foregoing symptom occurs, replace the laser shutter with the new type. In addition, remove the laser shutter arm
and apply a rice-grain sized amount of grease (PERMALUB G No. 2); about 30mg) evenly to the area [1] shown in P-4.
As for a machine having one of the serial numbers listed in “Affected Machines” below as “machines for which the shape
change of the laser shutter is carried out”, only application of grease is required: there is no need to replace the laser
shutter arm because the new type shutter has already been mounted onto them.
When replacing with the new type of laser shutter arm, there is no need to apply grease to it.
