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.
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.
