Step-by-Step Solution

  1. Queue Management: Delete stuck jobs.
  2. Reset: Power off to empty the RAM.
  3. Optimize: Lower print resolution settings.
  4. Update: Install the latest official firmware.

Prevention and Maintenance

Use the print-from-disk function for very large recurrent files.

Frequently asked questions

The error 320 indicates that the document you are attempting to print is too large for the current memory availability, causing the printer to stop.

Yes, by reducing the resolution of large images or splitting the job into smaller chunks.

Using original OKI toners ensures that the system works efficiently without extra load on the print engine controllers.

Some drivers allow you to set the processing method to 'Client-side,' which uses your computer's memory to process the image before sending it to the printer.
