Solutions

Quick Diagnosis

Error code 380 generally appears when attempting to print very complex documents, such as high-resolution PDFs with numerous images, which exhaust the printer's RAM.

Step-by-Step Solution

  1. Turn off the printer via the main power switch and disconnect the network/USB cable.
  2. Wait 2 minutes for the internal capacitors to fully discharge.
  3. Manually delete all pending jobs from the 'Printers & Scanners' folder in Windows.
  4. Restart the unit and send a simple document (test page) to confirm the error has cleared.

Prevention and Maintenance

Avoid sending files with unnecessarily high resolutions. Keep the printer firmware updated to optimize memory management.

When to Call a Technician

If the error occurs even with simple text documents, the mainboard may have a permanent physical memory failure.
