TR 7820 Document Feeder Quit Working

SteveB2 — Sat, 08 Aug 2026 03:59:21 GMT

I have a Canon TR7820. The scanner feeder no longer pulls the document into the printer to scan. I have to place the documents directly on the glass plate. Is there a fix for this?

Welcome @SteveB2

When a page is inserted to the ADF, does the scanner acknowledge it by waking up or playing a sound (tone)?

Have you opened up the ADF cover to look for obstructions, torn corner of a page etc?

The TR 7820 is almost 3 years old now. The printer has a 1-year warranty from Canon.

If you are within warranty, I would contact Canon support. Start by registering your printer in your MyCanon account. Then contact support 1-800-652-2666.

If it's outside warranty, you may want to pursue local repair as shipping and repair costs may exceed replacement value.

Troubleshooting the TR 7820 Auto Feeder Issue

If your TR 7820's automatic document feeder (ADF) has stopped working, follow these steps to identify and resolve the problem.

Check Document Placement

Ensure documents are aligned properly in the feeder.
Verify that the documents do not exceed the ADF's capacity.

Clean ADF Components

Clean the ADF rollers: Dust or residue can hinder document detection. Use a lint-free cloth with distilled water to gently clean the rollers.
Allow the rollers to dry completely before using the ADF again.

Inspect for Obstructions

Check the ADF for any obstructions that may prevent documents from being fed correctly.
Listen for any unusual noises when attempting to use the ADF, which may indicate mechanical issues.
