Shock Jitter at the Fusing Unit
Shock jitter when paper entered the fusing unit can cause horizontal black lines to appear 270 mm
(10.5”) away from the leading edge of the paper.
Cause:
When paper enters the fusing unit, the shock jitter is transmitted to the PTR unit, causing black lines to
appear about 270 mm (10.5”) from the leading edge of the paper.
 This occurs when paper longer than 270 mm is used
 The problem occurs from the first sheet of the print job
 The problem tends to occur with thick paper
 The problem tends to occur when printing halftone images
 To adjust the following settings, register beforehand the type of paper that you are using as a
custom paper.

1. Is the paper in use shorter than 270 mm (10.5”)?
Yes
Go to the next step.
No

2. Print the image on paper shorter than 270 mm. Is the problem resolved?
