Carriage jammed Was working normally but suddenly at far end of scanning travel, during a scan, the machine emitted a loud grinding noise (cogs slipping ?) and stopped working. Carriage is now jammed at the far end and the machine, although powered up, cannot respond.

    after a cartridge change & paper jam, the unit ratchets but won't operate. It tells me there is a problem with the paper tray, but it's fine; it says the carriage is jammed but I cleared it according to the demo.

The scanner works but makes a grinding noise that is getting worse


Normally Canon scanners work well for long time, Change the pickup rollers for every 250,000 pages and check other rollers for every 500,000 pages. In case you have been scanning documents with quite a good amount of dust, you may need to check at an earlier interval. Replace any worn out roller. Check if the small bearings at the end of each roller is perfect. Clean thoroughly all the rollers, dont use solvents. S. Mohan, Chenna, India

My scanner makes a loud noise on start up what is it ?


It is normal for your Epson scanner to produce noise on startup as it calibrates the motor that moves the scan mechanism when powered on. But if this is too loud than normal, it means that there may be already a problem with the motor and must be replaced if it wouldn't give out quality scans. Otherwise, it is working normally.

Grinding noise


The most common problem is that the pulley breaks, you might be able to see it through the glass. looks where the belt goes, and see if the pulley is broken.

also, some people forget to unlock the locking mechanism when the unit gets moved, the locking switch is on the side.
