J024/J074 when Feeding Thick Paper

Symptom

J024/J074 occurred when feeding thick paper.

Cause

The leading edge of the paper [A] hits the fusing entrance guide plate and the paper floats away from the transport belt [B] due to the thickness of the paper.

Solution 1

Set the paper in the trays neatly to prevent paper skew at the entrance of the fusing unit.

If this does not solve the problem, do Solution 2.

Solution 2

Adjust the angle of the transport belt against the fusing nip.

Mark on the black bracket: Circle (level) [A]

	Effect: -
	Side effect: A jam may occur when feeding rough surfaced A4 paper in LEF.

Mark on the black bracket: Triangle (high angle) [B]

	Effect: Rough surfaced A4 paper is fed smoothly.
	Side effect: Worm tracks and wrinkles may be made on plain or thin paper.

Mark on the black bracket: No mark (low angle) [C]

	Effect: Small size thick paper is fed smoothly.
	Side effect: A jam may occur when feeding curled paper.

Adjustment Procedure of the Separation Lever

1. Remove the fusing unit. (Removing the Fusing Unit)

2. Remove the springs of the paper transport belt unit [A].

   

3. Open the paper transport belt unit [A], and remove the separation lever [B].

   

4. Adjust the position of the separation lever according to the paper type and paper size.

   

   • When attaching the separation lever, pay attention to the following.
     
     • Align the '-' marking [B] on the separation lever with the center of the marking [A] on the paper transport belt unit.
     • Ensure that the actuator [C] on the separation lever enters the sensor.
