Honeywell PX940e ERR-105 Error: Solution Guide

The Honeywell PX940e ERR-105 error is a logic fault related to system data processing or internal memory. This code appears when the printer encounters malformed instructions or a memory addressing conflict while interpreting complex jobs. To fix the ERR-105 error on your Honeywell PX940e, clear the print buffers via a complete physical reboot.

Common causes

  • 1Memory conflict during ZPL/DPL command interpretation.
  • 2Temporary corruption in print cache.
  • 3Malformed command instructions from the host.
  • 4Outdated firmware with known RAM management issues.

Solutions

Quick Diagnosis

If ERR-105 happens repeatedly with specific software, there is likely an incompatibility with the command language (ZPL, DPL) the printer cannot handle correctly.

Step-by-Step Solution

  1. Turn off and unplug the printer for 60 seconds.
  2. Disconnect all data cables (USB/Ethernet) to rule out network or electric noise.
  3. Power on without data connections and check if the panel error persists.
  4. If it boots up normally, update firmware to the latest version to improve RAM handling.

Prevention and Maintenance

Avoid sending mass print tasks if firmware isn't current. Use high-quality cables and ensure port settings match your print standard.

When to Call a Technician

If ERR-105 persists upon startup even without cables, the main logic board is hardware-damaged and needs replacement.

Frequently asked questions

Error ERR-105 is a system memory error or a data processing fault, usually caused by a conflict in print file format interpretation.

Ensure print jobs are sent in the correct format (e.g., ZPL) and keep firmware up to date.

None, this is a logic board error and not physical consumable issue.

Only as a last resort if the error persists after firmware updates.
