Background
What this message usually means
HP uses 31.13 on MFP models in this Color LaserJet Pro family when the automatic document feeder jams during copy or scan handling. This is an ADF-path issue rather than a print-engine jam.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
Diagnosis
Likely causes
The original stack was skewed or fed badly through the ADF.
A small scrap remains in the ADF exit or scanner-lid path.
Damaged or curled originals were placed in the feeder.
Service
When service or replacement is more likely
- -This mainly affects scan and copy workflows, not standard print output.
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.
