Description
Horizontal black lines separated by approximately 56mm in halftones in the last half of the image and/or abnormal noise generation during warm-up under
the following conditions:
Immediately after having been idle for an extended period of time.
When the paper in use is larger than 8.5x11.
If the image is high density (containing many dots).
Solution
CAUSE:A change of material in the Paper exit Conveyance Roller/Upper (p/n 56AA53071) allows development of flat spotswhich can cause both noise and
transfer jitter lines to occur.
SOLUTION: To correct:
1. Ensure that the engine firmware is at the following levels:
a. 7155/7165 Print Control version 14 or later
b. 7255/7272 Print Control version 14 or later
Note : This is the lowestfirmware version that provides therequired dipswitch setting.
2. Set 25 Mode Dipswitch 26-7 to [ 1 ] to provide slight fixing roller rotation to prevent constant contact at the roller nip and avoid flat spot generation.
3. If the problem persists, apply Molytherm grease #2 to the surface of Paper Exit Drive Gear/2 (p/n 56AA77230).The grease can be sourced locally or online.
4. If the problem still occurs, replace the Paper Exit Conveyance Roller/Upper with theprevious type using the newly assigned part number (p/n 56AAK0090).
IMPORTANT : DO NOTorder theoriginal productionroller as p/n 56AA53070. To prevent a parts order for thepreviously utilizedroller from "subbing up" to
p/n56AA53071 (the current roller exhibiting the symptoms), adifferent part number has been assigned to thatoriginal production roller (p/n 56AAK0090).
5. In some situations, it may also require installation of a Ferrite Core on the network communication cable.

Description
Toner is scattered around images when printing on thick paper. This is particularly noticable with text.
Solution
CAUSE: Incorrect transfer/separation setting.
SOLUTION: Change soft switch 6, bit 3 to ON (switch 6, bit 4 should remain OFF).
Note : This setting affects copy quality only when the Thick mode is selected.
