Correcting skewed printing
If the printed output is repeatedly delivered with the image skewed
(crooked on the page), or the pages themselves are damaged on
arrival at the output bin, you may need to adjust the registration
transport roll (heavy paper) levers. This may occur with heavy weight
papers. Follow this procedure:
1. Open the right and left doors of the printer and locate the heavy
paper levers, behind areas 2 and 4.
2. Pull the levers forward (toward you) on the silver latch release.
3. Turn both levers to the left (counter-clockwise), as illustrated in
the following figur
Figure 7-1. Adjusting the registration transport roll levers
Note: If your system is equipped with the optional 7 by 10-inch
paper enablement kit, it has three levers, as illustrated below.
(This kit is not available for the Model 96 NPS.)
Turn the left-most lever to the left (counter-clockwise) and the
other two levers to the right (clockwise).
