Fix 'No Paper' Error on Brother MFC-EX670

The 'No Paper' message on the Brother MFC-EX670 occurs when the paper detection sensor fails to register the presence of sheets in the tray, even when loaded. This fault usually stems from dust accumulation on the feed rollers or misaligned paper guides. It is a common problem easily resolved with basic cleaning of the feeding mechanism.

Common causes

  • 1Crystallized paper dust on rubber rollers, reducing traction.
  • 2Misalignment of paper guides, preventing the stack from touching the sensor.
  • 3Optical sensor blockage due to debris or small adhesive labels.
  • 4Natural rubber wear after heavy and prolonged use.

Solutions

Quick Diagnosis

If the tray is full and the device still shows this error, observe if the pickup mechanism tries to spin but fails to move a sheet. If you hear the motor whirring without picking up paper, the issue is likely due to low friction on the rollers or a blocked input sensor.

Step-by-Step Solution

  1. Remove the paper tray entirely and take out all existing paper to check for curled or misaligned sheets.
  2. Clean the pickup rollers using a cloth lightly dampened with distilled water, rotating them manually to clean the entire surface.
  3. Inspect the interior of the paper cavity for loose labels or paper scraps that might be obstructing the optical paper sensor.
  4. Reinsert the tray, ensuring the side guides are adjusted firmly against the paper edges without compressing them.

Prevention and Maintenance

Fan the paper before loading to remove static electricity and prevent pages from sticking together. Clean the pickup rollers every 6 months or whenever you notice the device slipping while trying to feed the first page. Do not exceed the maximum fill mark in the tray.

When to Call a Technician

If the printer still shows the error after cleaning the rollers and verifying the sensor, the detection sensor itself may be damaged. Replacing this internal component typically requires authorized professional service.

Frequently asked questions

It is not a critical hardware failure, but it halts all productivity. You should resolve it promptly to prevent failed print jobs.

While incorrect paper size settings in your OS can occasionally cause issues, it is a physical feed problem in 90% of cases.

The printer supports standard bond paper (64-90 g/m2). Always check the package for compatibility with inkjet printing systems.

It depends on usage, but cleaning them every two ink cartridge changes is ideal for ensuring the feed system operates reliably.
