Pattern to record: A jam message remains even when the visible path is empty.

Locate the feed stage

A typical receipt printer feeds a continuous roll with a platen rather than separating stacked sheets. Check roll width, winding direction, cover closure and cutter clearance against the model’s media instructions. One possible explanation is that dust, scraps or adhesive prevent a flag from returning to its normal position.

Feed-path checks

1. Verify roll width and orientation, inspect platen pressure, sensors and cutter clearance.
2. Trace the jam location and operate the sensor gently with power removed.

Before inspecting the mechanism

The thermal head may be hot and the cutter can move automatically. Forcing a thin plastic flag can break it.

Correct the confirmed cause

If the checks support this cause, remove contamination or replace the damaged sensor or flag. Verification should cover short and long receipts, repeated cuts, cover latch and low-paper behaviour.

For an assessment of your receipt printer, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
