HP 13.XX Paper Jam Error Codes: What They Mean

13.XX is HP's paper-jam family, and it's the single most common error family in our service records for office LaserJets. The useful part is everything after the 13: it tells you where the paper stopped, which tells you where to look — and whether you're dealing with paper or with a worn part.

Reading the code: the jam zone map

Older LaserJets use two digits (13.01, 13.05, 13.20); newer FutureSmart models use letter codes (13.A2.D2, 13.B9.Cz). Either way, the code names a zone:

• 13.A1 / 13.A2 / 13.A3… — pickup jams at a specific tray (the number matches the tray). Paper never made it out of the tray.
• 13.B2 — registration/paper-path delay: paper reached the registration area late or stopped there. Along with 13.B9, this is one of the two jam codes we log most.
• 13.B9 — jam in the fuser area. The other of our two most-logged jam codes. Repeated 13.B9s often travel with fuser wear — see the 50.XX fuser guide.
• 13.D… / 13.E… — duplexer and output/delivery jams.
• 13.20 — paper detected in the path at power-on, or a jam the printer can't localize. Often a leftover scrap.
• 13.FF — a generic/multiple-jam report; clear everything and let it re-detect.

How to clear a jam without making it worse

1. Follow the panel's door sequence. The printer knows which zone tripped; it will point you to the right door or tray.
2. Pull paper slowly, with both hands, in the direction of travel. Yanking against the paper path is how a jam becomes a torn-scrap problem.
3. Look for the scrap. If the sheet tore, find the missing corner. A leftover scrap on a sensor flag will re-trigger the same code with no visible paper.
4. Check the zones people forget: the rear door, the duplexer, and under the toner cartridge.
5. Mind the fuser. If the jam is in the fuser area (13.B9), the fuser is hot — give it a few minutes before reaching in.

“Paper jam” but there's no paper

A jam code with an empty paper path is one of the most common calls we get, and it's almost never a ghost. Three real causes, in the order we find them:

• Worn pickup or feed rollers. When rollers can't grip, the sheet arrives late at the next sensor and the printer calls it a jam — even though the paper is still sitting in the tray. Roller wear is a scheduled-maintenance item, not a mystery.
• A paper scrap on a sensor. Small, easy to miss, and it will re-trigger the same zone code every time.
• A stuck sensor flag. The little plastic levers in the paper path can hang up after a rough jam clearance.

Patterns worth noticing in an office

• One tray jams, the others don't. That tray's pickup rollers are worn. Rollers wear per-tray, by use.
• Jams started after a toner or kit change. Check that everything reseated fully — doors, guides, cartridge.
• Jams track with certain paper. Heavy stock from the wrong tray, or paper stored somewhere humid, will jam a healthy printer. Office storage matters more than people think.
• It jams every morning, then behaves. Humidity again — overnight moisture in the top sheets of a full tray.

When it stops being a paper problem

Clear once, fine. Clear daily, and the printer is telling you something: the same zone code recurring means the rollers, separation pad, or sensor in that zone are done. A grinding noise alongside jams points at the drive train. And 13.B9 plus print-quality problems points at the fuser. All of these are routine on-site repairs on business machines — the code you wrote down tells the technician most of what they need before they arrive.
