Konica Minolta AccurioLabel 400i Error C-5101: Fix

The Konica Minolta AccurioLabel 400i error C-5101 indicates that the label material has suffered a transport failure inside the printer. This error usually activates when the paper path sensors fail to detect the leading or trailing edge of the sheet within the expected timing parameters. It is the most common issue when switching to new adhesive stocks.

Common causes

  • 1Label material misaligned on the supply spool.
  • 2Leaked adhesive contaminating the paper sensor.
  • 3Paper weight exceeding manufacturer specifications.
  • 4Worn-out feed rollers losing traction on the material.

Solutions

Diagnóstico rápido

The C-5101 error appears when there is a real jam or severe misalignment. Inspect the paper path; if you observe wrinkled or partially peeled labels, the fault is mechanical and requires path clearance.

Solución paso a paso

  1. Power off the printer and open the material supply compartment cover.
  2. Carefully remove the label roll if it is obstructing the path.
  3. Use a flashlight to inspect the paper path for leftover adhesive on the sensors.
  4. Gently clean the pass-through sensors with a lint-free cloth and verify the material alignment before restarting.

Prevención y mantenimiento

Always ensure label material edges are not damaged before loading. Use certified paper stocks to prevent adhesive buildup on sensors and drive rollers.

Cuándo llamar a un técnico

If the C-5101 error persists after loading new material correctly, a feed roller may be worn out or a sensor may have failed permanently.

Frequently asked questions

This code indicates a transport fault; the expected signal from the paper sensor did not arrive within the programmed time frame.

Yes, stop all printing to prevent adhesive material from wrapping around rollers, which is extremely difficult to clean.

Incompatible paper or adhesive types are a leading cause of frequent jams that trigger the C-5101 code.

Always load material correctly on the spool and ensure the paper thickness complies with device specifications.
