Cause:
Glossy vertical stripes [A] occur on sheets of a print job using paper smaller than the previous long print job on large size paper [B] with its edges contaminated by strips from cutting.
This problem can occur when:
- Using thick paper with edges contaminated by small burrs and strips created when the paper was cut.
- Printing images with large coverage areas (half-tones, etc.).
- Using very high-gloss paper
Solution:
Procure a fusing unit to be dedicated for long print jobs with a selected paper size, to avoid the occurrence of glossy vertical striping on prints. Up to four units can be registered for swapping the fusing unit for high volume print jobs on the same paper size.
- After a fusing unit dedicated to printing on one paper size for long print jobs is swapped into the machine, the registration number attached to the unit must be selected and the distance and page counters must be reset before that fusing unit.
These important settings are done with the "Adjustment Settings for Skilled Operators" on the operation panel of the main machine. Here is a list of the settings that must be done:
- [Fuser Unit No.] Select a number in the range 1 to 4 to assign a number to the machine.
- [Current Value: Distance Counter: Fuser Unit]
- [Current Value: Distance Counter: Fuser Cleaning Unit]
- [Current Value: Page Counter: Fuser Unit]
- [Current Value: Page Counter: Fuser Cleaning Unit]
