Worm Marks, Creases, and Fusing Errors on Envelopes
Worm marks or creases occur on envelopes. Or fusing errors occur.
Cause:
Worm marks and creases occur when envelopes containing moisture is used and lose rigidity is lost due to storage conditions or the conditions in which the envelopes are fed.
Fusing errors may be caused by the envelope nip width value in the initial setting being specified incorrectly.
Solution: (Worm Marks or Creases)
If the paper is not registered as custom paper, register the brand of the paper.
In [Detailed settings] for the custom paper you are using, select 1241: [Fusing Nip Width Adjustment], and then decrease the value in [Envelope] by 250 µm.
Print the image. Has the problem been resolved? (10 applicable envelopes)
Yes | Go to the next step. |
No | Start over from Step 2. |
Is the toner fusibility within the permissible range?
The required level of fusibility is as follows.
The printed image does not come off.
The toner does not come off even if it is lightly rubbed by a nail.
The toner does not come off even if it is rubbed by the cloth for cleaning the contact glass.
Yes | Finished! |
No | No further improvement is likely. |
Solution: (Fusing Errors on Envelopes)
If the paper is not registered as custom paper, register the brand of the paper.
In [Detailed settings] for custom paper, check 1244-01: [Fusing Pressure Roller On Before Fusing].
If it is set to "On", set it to "Off", go to the next step.
If it is already set to "Off", proceed to Step 4.
Print and check if the fusibility is within the acceptable range.
The required level of fusibility is as follows.
The printed image does not come off.
The toner does not come off even if it is lightly rubbed by a nail.
The toner does not come off even if it is rubbed by the cloth for cleaning the contact glass.
Yes | Finish! |
No | Go to the next step. |
Select 1241: [Fusing Nip Width Adjustment], and then increase the value in 02: [Envelope] by 250 µm.
Print and check if the fusibility is within the acceptable range.
The required level of fusibility is as follows.
The printed image does not come off.
The toner does not come off even if it is lightly rubbed by a nail.
The toner does not come off even if it is rubbed by the cloth for cleaning the contact glass.
Yes | Finish! |
No | Start over from Step 4. If the problem persists or is not reduced, there is no other solution. |
