Error C-01 Fujitsu DL2402: Communication Fix

The Fujitsu DL2402 error C-01 is a communication error resulting from a failure in the buffer memory's processing of data. It occurs when the data sent from the PC conflicts with the current memory state of the matrix printer. This guide provides the steps to clear the buffer and restore the connection between your host system and the hardware.

Common causes

  • 1Memory buffer saturation.
  • 2Defective interface cable (Parallel/USB).
  • 3PC/Printer driver synchronization issues.
  • 4Electrical interference on the data line.

Solutions

Quick Diagnosis

If the printer displays C-01, it will halt printing and ignore new jobs. Check the cable for loose connections or electromagnetic interference in the office environment.

Step-by-Step Solution

  1. Power Cycle: Shut down the printer for 30 seconds.
  2. Disconnect: Unplug the data interface cable.
  3. Flush Memory: Boot the machine without the cable to clear the memory buffer.
  4. Reconnect: Re-attach the cable and verify the PC interface is properly configured.

Prevention and Maintenance

Use high-grade shielded cables. Ensure the printer has a stable electrical ground to prevent data corruption during operation.

When to call a technician

If the error occurs consistently on different PCs or with different cables, the internal printer board interface has likely failed.

Equipment Technical Data

  • Technology: Dot Matrix Impact.
  • Component: 24-pin print head.
  • Consumables: DPK-2402 ribbon.
  • Connectivity: Serial/Parallel interfaces.
  • Maintenance: Periodic cleaning of the carriage assembly.
  • Official Drivers / firmware

Steps to follow

  1. 1

    Reset Connection

    Power off the printer and disconnect the interface data cable (parallel/USB).

  2. 2

    Flush Buffer

    Power on the printer without the data cable to clear any pending tasks in the RAM.

  3. 3

    Verify Driver

    Reconnect the cable and check your PC driver settings to ensure it is not set to 'offline'.

Frequently asked questions

C-01 usually indicates a buffer overflow error or a communication timeout during data reception.

It is a standard communication glitch, often solved by simply restarting the job.

Always use original DPK-2402 ribbons to protect the print head from friction and dry ink particles.

Use high-quality interface cables and keep cable length short to ensure reliable data transfer.
