Fujitsu FTP-342MCL Error E-06: Data Communication Fault

The Fujitsu FTP-342MCL error E-06 is a data communication notification. This issue occurs when transmission parameters, such as baud rate or flow protocol, do not match between the POS terminal and the printer. To fix the Fujitsu FTP-342MCL error E-06, you must verify port settings and the physical condition of the connection cables. This printer is highly regarded in commercial settings for its speed and durability under continuous use.

Common causes

  • 1Baud Rate Mismatch: Software attempts to send data at a speed the printer doesn't recognize.
  • 2Faulty Cables: Internal wire failures causing signal interruptions.
  • 3EMI Interference: Data cables too close to high-load electrical lines.
  • 4Port Error: The POS terminal doesn't have the port correctly assigned in the OS.

Solutions

Quick Diagnosis

If you receive E-06, the system is not receiving confirmed data from the printer. First, validate that the data cable is not under tension or excessively long. If everything looks correct, the issue usually lies in the software, specifically the baud rate settings.

Step-by-Step Solution

  1. Cable Check: Disconnect and reconnect the data cable (serial or parallel), ensuring there are no bent pins.
  2. Verify Baud Rate: Check that the transmission speed (baud rate) matches perfectly between the POS software and the printer.
  3. Isolation Test: Try with a new data cable to rule out internal cable breaks.

Prevention and Maintenance

Avoid using low-quality or homemade data cables, as they lack shielding against electromagnetic interference common in checkout environments. Keep connections away from heat sources and high-load electric motors.

When to Call a Technician

If the error E-06 persists after adjusting software parameters and trying new cables, the interface chip on the printer's mainboard might have experienced a discharge, requiring professional assistance for replacement.

Frequently asked questions

The E-06 indicates a data communication error between the POS system and the printer, typically caused by incorrect port settings.

No, it's a data flow configuration error, though it prevents printing until the system is synced.

It uses 80mm wide thermal paper, ideal for high-readability, durable receipts.

We recommend checking the configuration after every sales software update or changes in computer equipment.
