Common causes

  • 1Paper loaded incorrectly (out of guides).
  • 2Feed rollers worn or coated in dust/paper fibers.
  • 3Tray presence sensor blocked by debris.
  • 4Wrong paper size configured in the panel vs physical tray.

Solutions

Quick Diagnosis

The error 0x40 appears if the unit attempts to pick paper and fails, or if it detects a mismatch between software settings and the physical tray sensor. Check if paper is correctly placed against the lateral guide.

Step-by-Step Solution

  1. Remove the tray where the error occurred.
  2. Fan the paper to separate sheets and prevent static sticking.
  3. Clean the rubber rollers with a clean cloth and distilled water (no harsh chemicals).
  4. Check the sensors to ensure they are not blocked by paper scraps.
  5. Reinsert the tray firmly and restart the printer.

Prevention and Maintenance

Use high-quality paper and store reams in a dry area; moisture is the biggest enemy of feed rollers in high-volume printers like the Enterprise.

When to Call a Technician

If the 0x40 error persists after cleaning the rollers and checking the paper, the paper presence sensor or the tray motor may have reached its end of life.
