Canon printer error code 6900 indicates an ASF (Automatic Sheet Feeder) position fault, meaning the printer's paper feed mechanism is stuck, misaligned, or obstructed and cannot return to its home position. This error commonly occurs when paper is jammed inside the feeder, the ASF motor has failed, or debris is blocking the feed rollers. While this is a medium-severity error, it is often fixable at home without professional help by clearing obstructions and resetting the printer.

How to Fix Error Code 6900

  1. Power Off and Unplug the Printer

    Always unplug the printer from the power outlet before reaching inside or inspecting internal components to avoid electric shock or injury from moving parts.
  2. Remove All Paper from the Input Tray

  3. Clear Any Paper Jams

    Pull jammed paper slowly and in the correct feed direction. Forcing or tearing paper can damage the feed rollers or internal sensors, making the problem worse.
  4. Inspect and Clean the Feed Rollers

  5. Check for Obstructions in the ASF Mechanism

  6. Plug In and Perform a Power Reset

  7. Run a Printer Reset Using the Control Panel

    A factory reset will clear custom network settings, stored jobs, and preferences. Note down your Wi-Fi credentials and settings before performing this step.
  8. Update or Reinstall Printer Drivers

  9. Test Print and Monitor

When to Call a Professional

If you have completed all the steps above — cleared jams, cleaned rollers, reset the printer, and updated drivers — and the error code 6900 still appears, the ASF motor or its associated sensor may have failed internally. Additionally, if you hear grinding or clicking noises coming from the feed mechanism during startup, or if you find visibly cracked or broken plastic gears inside the printer, these are signs of mechanical damage that requires professional repair. Contact Canon's official support line or take the printer to a Canon-authorized service center. For older or lower-cost Canon printer models, the cost of professional repair may exceed the value of the printer — in that case, replacement is worth considering.

Frequently Asked Questions

What does error code 6900 mean on a Canon printer?
Error code 6900 on a Canon printer means the Automatic Sheet Feeder (ASF) has detected a position fault. The ASF mechanism — which picks up and feeds paper into the printer — is unable to move to its correct home position, usually because of a paper jam, debris, dirty rollers, or a failed motor or sensor.
How do I fix Canon error 6900 without calling a technician?
Start by unplugging the printer, removing all paper, and carefully clearing any jammed or torn paper from the paper path. Clean the feed rollers with a damp lint-free cloth, check for debris near the ASF mechanism, then plug the printer back in and power it on. If the error persists, perform a factory reset from the control panel and reinstall the latest printer drivers from Canon's website.
Why does my Canon printer keep showing error 6900 after I clear the jam?
If the error returns after clearing a jam, there may be a small torn fragment of paper still inside the paper path that is hard to see, or the feed rollers may be worn and slipping. It is also possible that the ASF position sensor is dirty or faulty. Try using a flashlight to thoroughly inspect all paper path areas and clean the rollers. If the error persists, the ASF motor or sensor may need professional replacement.
Can I use my Canon printer if it shows error 6900?
No. Error code 6900 is an active fault that prevents the printer from operating normally. The printer will typically refuse to print until the ASF fault is resolved. Attempting to force print jobs through while this error is active can worsen the jam or cause further mechanical damage to the feed mechanism.
How much does it cost to repair a Canon printer with error 6900?
If the fix requires only cleaning and a reset, there is no cost beyond your time. If the ASF motor or position sensor has physically failed, professional repair at an authorized Canon service center typically costs between $50 and $150 depending on the model and labor rates in your area. For budget inkjet printers, it may be more economical to replace the printer than to pay for professional repair.
