Jam (Main Unit)
0128 jam code due to high density image output in a high
temperature/humidity environment
[Symptom]
0128 jam may occur when an image of high density exceeding 200% is printed out on a sheet of paper that has been left in a
high temperature/humidity environment.
0128: Bypass Sensor 1 Delay Jam (PS322)
[Cause]
The output sheet of a high density image has a tendency to curl upward.
As the paper that has been left in a high temperature/humidity environment contains a plenty of moisture in it, the more the paper
curls, the more its elasticity gets reduced and it would have a folded corner as a result.
If a sheet of paper that is curled upward has a folded corner at the flapper [a] that switches the single fixing path and the tandem
fixing path, the above mentioned symptom may occur.
