Symptom
The following may occur when printing onto the envelopes shown below:
- Wrinkles
- Paper transport issues
- Flaps stick (closed) to the body of the envelope
Note: If the envelopes are fed in the SEF direction, they tend to warp in between the
PTR unit and fusing unit.
C6, 105x235, DLX
Major brands:
[A]: C6, [B]: 105x235, [C]: DLX
Cause
The heat of the fusing process may cause wrinkles to form or the adhesive on the flaps to
melt if the flaps are folded.
Solution
When feeding the types of envelopes described above, feed them from the bypass tray, in
the LEF direction (from the trailing edge), with the flaps open.
