Troubleshooting
Suggested Solutions
5. Change the Pre Gate Roll Adjustment setting.
• This feature is enabled only when printing on paper that is 290 mm or larger in landscape,
or on front and back sides of trays 1, 2, or 3, or the back sides of trays 6 - 9.
• Use this feature to adjust the behavior of the pregate roll mechanism. When paper feeds
through the press, it stops once and pressure is applied in order to correct registration
and skew. The pregate roll is one of the mechanisms that applies pressure to the paper.
• The settings available for the this feature include:
- System Default: The pregate roll setting is automatically switched according to
paper weight.
- On: To hold the paper with the pregate roll for paper weight 220 g/m² or less, select
this option only if the Regi-Loop adjustments did not correct misregistration or if
Alignment Profile did not correct image skew.
- Off: For paper weight 221 g/m² or greater where the leading edge of the paper is
torn, select this option to release the paper from the pregate roll.
Note
Selecting Off disables the Alignment Roll Pressure setting.
• After changing the setting run test prints and evaluate the output.
6. Change the Fuser Speed Adjustment setting.
• This feature is used to adjust the fusing speed to improve print quality when the image
is distorted (either stretched or shrunk).
- If the image is shrunk, increase the fuser speed. If the fuser speed is set too high,
it may cause paper jams.
- If the image is stretched, decrease the fuser speed.
• This feature is accessed from Stock Library Manager > Stock Properties > Advanced
Stock Setup > Fuser Speed Adjustment.
• Increase or decrease the fuser speed in increments of 0.1%.
• After each incremental adjustment, run test prints and evaluate the output to determine
if additional adjustments are required.
Problem
Unfused Dry Ink / Toner on Output
Suggested Solutions
1. Change the Fuser Temperature Adjustment setting.
Tip
Changing the default setting of 0 (zero) is a temporary solution because environmental
conditions vary from day to day. Upon completion of the print job, the recommendation
is to return the option to its default setting.
• User this feature to adjust the fuser temperature.
• If dry ink / toner comes off the paper, especially with special media, resolve the problem
by increasing the fusing temperature.
