Step-by-step Solution

  1. Open the front loading tray.
  2. Remove the paper and verify no bits of torn paper are stuck inside.
  3. Fan the paper stack to prevent sheets from sticking.
  4. Reload the paper and push the guides snugly against the stack.
  5. Press the 'OK' button to clear the alert.

Prevention and Maintenance

Use high-quality paper to prevent dust buildup on feed rollers. Keep the printer in a cool, dry environment to maintain paper integrity.

When to Call a Technician

If paper detection fails even after hardware cleaning, internal sensor failure is likely, requiring professional maintenance.
