077-104 Fusing Unit Exit Sensor Off Jam (Short)
Version 1.0
Status Indicator RAPs
077-104 Fusing Unit Exit Sensor Off Jam (Short)
BSD-ON: CH10.3, CH4.1, CH10.4
The time taken for the Fusing Unit Exit Sensor to turn from ON to OFF is shorter than the spec-
ified time.
Cause/Action
Check the following:
• The Fusing Unit Exit Sensor (Input Check [071-106]) for operation failure. (PL 7.1)
• The Regi Sensor (Input Check [071-105]) for operation failure. (PL 15.1)
• The Main Drive Motor (Output Check [042-001]) for operation failure. (PL 3.1)
• The Invert Motor (Output Check [071-003] (Exit)) for operation failure. (When Duplex is
installed) (PL 17.1)
• The Heat Roll for wound up, stuck paper.
• Usage of out of spec paper.
If no problems are found, replace the ESS/MCU PWB (PL 18.3).
077-106 Fusing Unit Exit Sensor On Jam
BSD-ON: CH10.3, CH4.1
The Fusing Unit Exit Sensor did not turn ON within the specified time after the Regi Clutch On.
Cause/Action
Check the following:
• The Fusing Unit Exit Sensor (Input Check [071-106]) for operation failure. (PL 7.1)
• The Main Drive Motor (Output Check [042-001]) for operation failure. (PL 3.1)
• The Regi Clutch (Output Check [071-001]) for operation failure. (PL 15.1)
• The Fusing Unit Exit Chute for improper installation and deformation.
• The Transfer Unit for a decrease in the transportation force.
• The Drive Gear for wear and damage.
• The Heat Roll for wound up, stuck paper.
• A paper transportation failure due to foreign substances on the paper path.
• Usage of out of spec paper.
• Check that the width of the lead edge of the fed paper is more than 190 mm (the distance
between 2 fingers of the ERU).
• If the width of the fed paper is equal to or less than 190 mm and the jam occurs continu-
ously, add the Finger Assy (019K 12750) to the center of the ERU. (See the photo.)
