Common causes

  • 1Tray not inserted all the way into the unit.
  • 2Paper scraps blocking the end-of-paper sensor.
  • 3Worn or dusty rubber feed rollers.
  • 4Mechanical misalignment in the tray base.

Solutions

Quick Diagnosis

Error 60.02 usually pops up upon startup or when a print job begins. Check if the paper tray is fully flush with the device housing and listen for grinding sounds that indicate mechanical trouble.

Step-by-Step Solution

  1. Pull the paper tray out completely.
  2. Inspect the cavity and feed roller area for scraps of paper or staples.
  3. Adjust the paper guides; they should hold the paper stack snugly without causing compression.
  4. Check the tray sensors; they should move freely to confirm the tray presence.
  5. Reinsert the tray carefully until it clicks fully into the chassis.

Prevention and Maintenance

Do not overfill the tray above the 350-sheet limit. Periodically clean the rollers with a rubber-safe cleaning solution to maintain traction. Store paper in a moisture-free area to prevent feeding issues.

When to Call a Technician

If cleaning and reseating do not resolve error 60.02, the tray lift motor or internal optical sensor likely requires technical inspection.

Frequently asked questions

This error means the system fails to detect the paper tray or the paper-out sensor is blocked by debris.

Yes, printing will be prevented until the paper feeding system is restored and the tray is correctly recognized.

Using heavy-weight paper or humid paper can lead to detection failures or feeding jams.

Keep the feed rollers clean and stay within the 350-sheet tray capacity.
