8. Troubles Related to Paper Feeding and Delivery (Main)
[A] Crease (Paper bent)
[B] Worm track (No creases but white ghosting on solid-fill parts)
Cause:
When solid-fill images are printed on both sides of thin paper, the paper has difficulty spreading in the
main scan direction at the fusing nip on Side 2, resulting in creases or worm tracks.
Solution:
• If you change the fusing nip width, the margin at the leading edge may be reduced, resulting in
paper jams related to insufficient separation. In such a case, perform the solution described in see
page 252 "Paper Jams Occur with Crumpling of the Leading Edge When Thin Paper Is Used".
If the paper is not registered as custom paper, register the brand of the paper.
(a) Troubleshooting Flow A
1. In [Detailed settings] for custom paper, select 1232: [Fusing Temperature], and then note
down the value in [Heat Roller Temp].
• 1232-01: Fusing Temperature: BW/FC/FCS: Heat Roller Temp
• 1232-06: Fusing Temperature: FCS: Heat Roller Temp: Clear/Special
• 1232-07: Fusing Temperature: FCS: Heat Roller Temp: White
• 1232-08: Fusing Temperature: FCS: Heat Roller Temp: Metallic
• 1232-26: Fusing Temperature: S: Heat Roller Temp: Clear/Special
• 1232-27: Fusing Temperature: S: Heat Roller Temp: White
• 1232-28: Fusing Temperature: S: Heat Roller Temp: Metallic
• 1232-46: Fusing Temperature: BW/FC/FCS: Fuser Setting HQ: Heat Roller Temp
• 1232-51: Fusing Temperature: FCS: Fuser Setting HQ: Heat Roller Temp: Clear/Special
• 1232-52: Fusing Temperature: FCS: Fuser Setting HQ: Heat Roller Temp: White
• 1232-53: Fusing Temperature: FCS: Fuser Setting HQ: Heat Roller Temp: Metallic
• 1232-71: Fusing Temperature: S: Fuser Setting HQ: Heat Roller Temp: Clear/Special
• 1232-72: Fusing Temperature: S: Fuser Setting HQ: Heat Roller Temp: White
• 1232-73: Fusing Temperature: S: Fuser Setting HQ: Heat Roller Temp: Metallic
2. Decrease the temperature setting for the fusing heat roller by 5°C.
3. Print the image. Has the problem been resolved? (20 or more sheets of A4 paper)
