Common causes

  • 1Buffer overflow due to large or complex file data.
  • 2Corrupt print data packets in the memory cache.
  • 3Defective USB communication interface.
  • 4Outdated device firmware causing processing errors.

Solutions

Quick Diagnosis

The error is confirmed when the indicator lights signal E5 and the printer stops responding. If this occurs after sending large documents, it is definitely a memory-related issue rather than a mechanical jam.

Step-by-Step Solution

  1. Physical Shutdown: Disconnect the printer from the wall outlet while it is still on.
  2. Drain Power: Hold the power button for 15 seconds to discharge residual power from the internal capacitors.
  3. Clear Queue: On your computer, open the printer queue and delete any pending documents that might be stuck.
  4. Reconnect: Plug the printer back in and power it up.

Prevention and Maintenance

Keep your device firmware updated annually to optimize resource management. Always use high-quality, original toners to ensure perfect sensor communication with the print engine. Avoid using damaged or low-quality USB cables.

When to Contact a Technician

If the error persists after a full power cycle and no jobs are pending, the internal formatter board may require replacement.
