Background
What this message usually means
Lexmark groups several MP-feeder jam codes under Paper jam in the multipurpose feeder on the C4342 and XC4342 family. It usually means the sheet fed from the MP path never arrived at or never cleared the expected sensor correctly.
Before the message
What users usually notice first
Messages like this often appear after a hidden paper-path interruption, tray setup issue, or a small obstruction that is easier to miss than a full visible jam.
Diagnosis
Likely causes
The media in the multipurpose feeder is skewed or unsupported.
A hidden scrap remains in the MP path.
The job is trying to use thick, curled, or mixed media that will not feed cleanly.
Service
When service or replacement is more likely
- -Use tray feed for normal office stock if the MP path is only failing on specialty media.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
