Background
What this message usually means
HP groups 13.14 and 13.15 together for duplexer jams on this LaserJet Pro family. The printer detected a two-sided path jam and needs the duplex path cleared before it can continue safely.
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
Paper stalled in the duplex path during two-sided printing.
The duplex pan or guide area still contains a torn scrap.
Curled or heavy media failed to reverse cleanly through the duplex path.
Service
When service or replacement is more likely
- -If only duplex jobs fail, the problem is often isolated to the reverse path rather than the main tray pickup.
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.

Source notes
HP's official article groups 13.14 and 13.15 as duplexer jams and walks through opening the duplex pan, clearing paper, and rechecking the path.
Built around official HP LaserJet Pro M329, M428, and M429 support guidance. Exact panel formatting can vary a little by printer or MFP model, but the jam families and first checks stay close across the range.
Printer error codes can vary a little by firmware, region, and exact model variant. Use this guide as a family-level starting point and stop if the next step would require disassembly or service-mode changes.
