Correcting Image Unevenness / Improving Feedability

When outputting documents (data) containing a high percentage of text and images onto large sized paper, there may be occasions where the images are uneven.

Image unevenness on paper sized A4 w/v, 8.5 e 11 w/v or larger can be corrected using the Compression Adjusting Lever of machine fusing unit.

If the feedability drops when you print on small-sized thick paper (the length in the conveyance direction is less than 200 mm / 7.87"), or if you print on thin coated paper (less than 100 g/m² / 27 lb Bond), you can increase the crimping compression of the machine fusing unit and improve the feedability.

Follow the steps below to adjust the crimping compression.

NOTICE

• Do not move the Compression Adjusting Lever for other purposes than this adjustment. In Normal Mode, make sure that the Compression Adjusting Lever is positioned in line with the middle triangle.

1

Open the front panel of the machine.

2

Tilt Lever [M1] to the left and pull out Fusing Conveyance Unit.

3

Lift the Lever [M6] (A in the figure), and open the Left Cover of the Fusing Unit to the left.

4

When correcting image unevenness of the large sized paper, slide the Compression Adjusting Lever to the right and align the lever with the right-most triangle.

5

For improving feed performance when printing onto small sized cardboard or thin coated paper, slide the Compression Adjusting Lever to the left and align the lever with the left-most triangle.

6

Return the Left Cover of the Fusing Unit to its home position. Push the Fusing Conveyance Unit back to its home position and rotate the Lever [M1] right until it is in its original upright position.

7

Close the front panel on the machine.
