Xerox AltaLink C8045 error 042-326: Quick Fix

The Xerox AltaLink C8045 error 042-326 indicates a conflict in paper size detection within the input trays. This alert appears when the system recognizes a discrepancy between screen settings and physical tray adjustments. To fix error 042-326, it is essential to check the physical paper load and sensor alignment. This multifunction office device relies on accurate media sensing to prevent operational downtime.

Common causes

  • 1Misalignment of physical tray paper guides.
  • 2Accumulation of dust or scraps on optical sensors.
  • 3Faulty or disconnected paper size detection sensor.
  • 4Media size setting mismatch between software and physical media.

Solutions

Fast Diagnosis

Error 042-326 occurs when the machine cannot validate paper dimensions. If your panel displays this code, check if the tray was moved recently or if debris is obscuring the optical sensors.

Step-by-Step Solution

  1. Remove the tray completely from the copier.
  2. Clean the sensors using a dry, soft cloth.
  3. Realign the side guides to ensure they touch the paper stack snugly.
  4. Close the tray and verify if the display recognizes the paper size correctly.

Prevention and Maintenance

Clean the feed rollers every 50,000 pages. Avoid storing paper in humid environments as this triggers false sensor readings. High-quality paper helps preserve the feeding mechanism.

When to Call a Technician

If the error persists after resetting, the paper size sensor might be faulty or disconnected, requiring professional hardware repair.

Frequently asked questions

This error occurs when the paper size sensor detects a mismatch between the system settings and the physical tray configuration.

It is not critical; it is typically resolved by adjusting the paper guides or clearing debris from the sensors.

We recommend genuine Xerox AltaLink C8000 series toner to ensure print quality and avoid internal errors.

Ensure paper is loaded correctly against the guides and keep the tray area clean from dust and paper scraps.
