Konica Minolta AccurioPress Paper Jam & Feed Error Codes Explained — Causes & Fixes

Paper jams are the single most common reason a production press stops mid-job — and the most common reason for a same-day service call. Most jam and feed errors are recoverable in minutes if you know where to look, and the error code itself tells you exactly which zone of the paper path to check. Here’s how to read those codes and fix the underlying cause, not just clear the paper and hope it doesn’t happen again.

Why jam codes are zone-based

Konica Minolta AccurioPress machines divide the paper path into zones — feed, transport, fusing, duplex, and finishing — and the error code tells you which sensor along that path failed to detect the paper moving as expected. This is genuinely useful information: instead of opening every panel on the machine, the code points you to one specific area first.

1. Feed tray jams

What it usually means: Paper failed to pick up correctly from the tray, or multiple sheets fed together.

Common causes:

• Paper not fanned or loaded correctly (stuck sheets, especially in humid conditions)
• Tray guides set too loose or too tight against the paper stack
• Worn pickup or feed rollers — these have a service life and wear faster with high-volume daily use
• Paper stock heavier or lighter than the tray is configured for

What to check first: Remove the stack, fan it properly, and check that the guides sit snugly without compressing the paper edges. If jams keep happening at the feed stage specifically with one particular paper stock but not others, the issue is very likely settings mismatch (tray weight/type setting) rather than a mechanical fault.

2. Transport/registration zone jams

What it usually means: Paper reached the feed stage but didn’t arrive at the next sensor in the expected time — usually a transport roller or registration timing issue.

Common causes:

• Debris or paper dust buildup on transport rollers
• Skewed paper entering the transport path
• Registration rollers worn or misaligned

What to check first: Clean visible transport rollers of dust and debris first — this alone resolves a surprising number of intermittent transport jams. If the jam recurs at the same location repeatedly even after cleaning, it points to roller wear rather than debris.

3. Fusing unit jams

What it usually means: Paper failed to pass cleanly through the fuser, or curled/wrapped around a fuser roller.

Common causes:

• Paper too heavy, too light, or too moist for the fuser temperature setting
• Fuser roller wear or release agent depletion
• Incorrect paper type setting causing wrong fuser temperature for that stock

What to check first: Fuser jams are one of the more serious jam types since they can involve heat and require care when clearing — always let the unit cool per the machine’s guidance before opening it. If jams happen consistently on one specific paper type, check that the print driver’s paper type setting actually matches what’s loaded, since fuser temperature is set based on that.

4. Duplex unit jams

What it usually means: Paper failed to flip and re-feed correctly during double-sided printing.

Common causes:

• Curled paper (very common with stock stored in humid conditions)
• Duplex path rollers worn or dirty
• Paper weight outside the duplex unit’s rated range for that stock

What to check first: Check paper flatness first — curled sheets are the most frequent cause of duplex jams and are a storage/environment issue, not a machine fault. If flat paper still jams consistently in duplex, the duplex rollers likely need inspection.

5. Finisher/output jams

What it usually means: A finishing error — stapling, folding, or booklet unit — failed to detect paper where expected.

Common causes:

• Paper stack exceeding finisher capacity for that job type
• Worn finisher transport components
• Stapler misalignment or depleted staple cartridge

What to check first: Confirm the job’s finishing settings (staple position, booklet fold type) actually match what the finisher is physically set up to do — a surprising number of “jams” here are actually configuration mismatches rather than real paper jams.

A pattern worth remembering

Across all zones, the same three questions narrow down almost every jam cause quickly:

1. Does it happen with all paper stocks, or just one? — Points to settings/stock issue vs. mechanical issue
2. Does it happen at the same physical location every time? — Points to roller wear or a mechanical fault at that spot
3. Did it start suddenly, or gradually get more frequent? — Sudden onset often means a setting was changed or paper stock changed; gradual worsening usually means a part is wearing out

When a “quick clear” isn’t enough

Clearing the paper and restarting the job gets you running again, but if the same jam code repeats within a day or two, the underlying cause hasn’t been addressed — and running components under continued strain (worn rollers, misaligned parts) risks more expensive damage down the line. A jam that recurs three or more times in a week is worth a proper inspection rather than repeated manual clears.
