Attaching the Side Fences and End Fence Correctly
The side fences and end fence are attached correctly
Check if the side fences and end fence are attached correctly.

The side fences are not attached correctly
The side fences are positioned too widely.
There is a gap (A) between the side fences and the paper, so the paper fed is skewed towards the paper feed direction.

The side fences are positioned too narrowly.
The side fences are positioned too narrowly so that the paper is arched, causing the paper's resistance to be lifted at the front edge, resulting in paper misfeeds.

Solution:
Lifting the paper with it arched horizontal to the paper feed direction, measure with a scale the gap between the paper and side fences.

Position the side fences so that the gap between them and the paper is 1 mm to 2 mm.

To move the side fences, loosen the screws on their arms to unlock them.
The end fences are not attached correctly
The end fences are positioned too widely.
The gap (A) between the end fence and paper, and the gap between the faceplate and paper add up to 3 mm (0.1 inches) or more. The paper is misaligned backward, causing double feeding.

The end fences are positioned too narrowly.
The end fence is positioned too narrowly so that the paper is arched, causing the paper's resistance to be lifted at the front edge which results in paper misfeeds.

Solution:
Lifting the paper with it arched vertical to the paper feed direction up to the bottom part of the end fence leaf spring, measure with a scale the gap between the paper and end fence.

Position the end fence so that the gap between it and the paper is 1 mm to 2 mm.

To move the end fence, unlock it.
