Table 3-58 Causes and solutions for residual media jams (continued)
Cause Solution
The sensor detecting a residual media jam is
not working.
Test each sensor using the manual sensor test. See
Manual sensor test
on page 289 for information. If the sensor does not respond, replace the
component indicated:
●
TOP sensor (PS5): Replace the registration sensor assembly. See
Registration sensor assembly on page 142.
●
Fuser-output sensor (PS6): Replace the fuser. See Fuser on page 93.
●
Fuser loop sensors 1 and 2 (PS7 and PS8): Replace the fuser. See
Fuser
on page 93.
If service was recently performed on the
product, a sensor connector might be
disconnected.
Run the manual sensor tests to verify which sensor detects the media. See
Manual sensor test on page 289 or Tray/Bin manual sensor test on page 300
for information. Reconnect the corresponding sensor connector:
●
TOP sensor: Connector (J122) on the DC controller PCA
●
Fuser-output sensor: Connector (J131) on the DC controller PCA
●
Fuser Loop sensor 1 or 2: Connector (J131) on the DC controller PCA
Jams in Tray 3, 4, 5, and 6
Table 3-59 Causes and solutions for pickup delay and pickup stationary jams
Cause Solution
The paper-feeder pickup roller is worn or
deformed.
Replace the pickup roller. See
Pickup roller, separation roller, and feed roller
(1 x 500-sheet and 3 x 500-sheet paper feeders) on page 99.
The paper-feeder separation roller is worn or
deformed.
Replace the separation roller. See
Pickup roller, separation roller, and feed
roller (1 x 500-sheet and 3 x 500-sheet paper feeders) on page 99.
The paper-feeder feed roller is worn or
deformed.
Replace the feed roller. See
Pickup roller, separation roller, and feed roller (1
x 500-sheet and 3 x 500-sheet paper feeders) on page 99.
Poor contact of the paper-feeder media-feed
sensor connectorS
A tray feed sensor is defective. Run the manual sensor test to verify that the paper-feeder media feed sensor is
functioning properly. See
Tray/Bin manual sensor test on page 300 for
information. If it is not, replace the paper pickup assembly of the specific tray.
Poor contact of a paper-feeder pickup
solenoid drive connector
The paper-feeder pickup solenoid is defective. Run the solenoid drive test in the component test (see
Component tests
on page 314) to verify that the paper-feeder pickup solenoid is functioning
properly. If it is not, replace the paper pickup assembly of the specific tray.
Poor contact of paper-feeder pickup motor
drive connector.
The paper-feeder pickup motor is defective. Run the pickup motor drive test in the component test (see
Component tests
on page 314) to verify that the paper-feeder pickup motor is functioning
properly. If it is not, replace the pickup assembly of the specific tray.
