Jams Related to Duplex/Invert in Short Grain and Thickest Paper
Cause
An insufficient force of transferring thick papers causes a high frequency of jams (particularly J080,
J085, and J086).
This is likely to occur if:

Transfer roller is dirty.

Using paper having high rigidity for bending/folding, regardless of paper weight.

Transferring the paper with long grain.
Solution
Carry out the following solutions.

Clean the transfer rollers around the locations where jam occurs.

Use a paper with short grain.

For duplex printing, print one side at a time (set the sheet that printed side 1 to the same tray again
to print the other side).

Switch the paper exit mode to the face-up (normal paper output).

If the problem is not solved with the above, change paper to other that has less paper weight.
Roller Marks on Buffer Pass Unit
In printing a solid image with high coverage, two 14mm-width bands are generated at 33 mm away from
the center of transfer on the 2nd side in duplex printing or on the side where image transferred in
simplex face-down.
