SUBJECT: PAPER FEED JAM
„
PAPER PATH
SYMPTOM:
A non-paper-feed jam occurs when the paper tray is almost full.
CAUSE:
PARTS
SOLUTION:
Determine the cause of the jamming issue.
1. Find the root cause (is jamming related to the friction pad or not?)
(1) Check the machine’s production date.
Please check the machine’s serial number. A list of serial numbers of the affected machines is can
be found in Units Affected.
(2) When does the non-paper-feed jam occur?
Basically, if the non-feed jam is caused by the friction pad, it only occurs when the paper tray is
almost full. Please check the amount of paper in the tray. Also, if the paper orientation is Short Edge
Feed, the occurrence rate will be higher.
(3) Check the mold number of the friction pad.
There is a Mold Number indication located
here: (1 or 2)
Mold 1: Good friction pad
Mold 2: Possible bad friction pad

„
The non-paper-feed jam is caused by a burr on the top surface of the Friction Pad. This burr was generated
due to a mold failure. Two molds were used to produce the Friction Pad. The Friction Pad with the burr is
from mold number 2 only.

From the above 3 points, please verify that the non-paper-feed jam is caused by the friction pad.
2. If a symptom is related to the friction pad, please try the following actions:
1. Remove the burr using #800 to #1000 grit sandpaper or emery cloth. To do this, first, remove the
friction pad from the unit. Second, place the sandpaper on a flat surface. Then invert the friction
pad and remove the burr as follows: Put the friction pad on the sandpaper, move it 2 or 3 times
in only one direction (in a straight line, not circular) as shown below. As a precaution, do not
move in two directions (for example, do not move it backwards and forwards). To feed the paper
smoothly, grinding should be in one direction.
Friction PadA2672831 or
A8602831
Move the friction pad in a straight line and in only one
direction - about 50 mm x 2 or 3 times
Sandpaper (#800 to
#1000 grit)
After removing the burr by sandpaper, please check paper feed when the paper tray is full.
2. If after performing the above procedure the nonfeed jam continues to occur, replace the friction
pad.
3. If the symptom is NOT related to a bad friction pad, please do the following:
(1) Check the paper feed clutch
If the lot number of the paper feed clutch is 339, this clutch may not produce the necessary torque.
(For more detail, please refer to Technical Service Bulletin B089/B093 - 005).
In this case, please replace the paper feed clutch.
(2) All other cases
Please try to adjust the bottom plate pressure with SP mode.
(Please refer to B089/B093 Service Manual section 7.3 - Paper Feed Troubleshooting)
