Our scanner is making a slight grinding noise when we scan documents, sounds like the drive belt/chain is sticking. How do we remedy this before it gets worse? Thanks Antony

You need to clean and lubricate scanner rails.

Testimonial: "Thanks for the help, how is the best way to do this?"

    You ned to remove copy glass and on the every side of scanner rails apply grease small amounts, but before clean the rails with wd40, both sides up and down rails.

Upon completion of OCR scanning, why does the printer make a grinding noise?

When you scan the document, the laser module moves on from the start point of the location to the end point of the location boundary for scanning the document and then it comes back to the initial position to the start point, so while moving the laser module it makes some sound. Still it is advised to take the printer to the nearest Canon Service Center to check if it requires any servicing. Please find the link below:

I was in the process of making copies, when my Epson RX700 suddenly made a loud grinding noise. It then stopped working and displayed an error message: Scanner error occurred...Please see...

There are two drives in the printer. One moves the print head (cartridge) back and forth across the paper. Check to see if the "rubber band" drive belt is slipping or broken off. There is also a roller motor which feeds the paper. This has nylon gears which can make a grinding sound if one of the gears gets stuck. Make sure there are no pieces of paper stuck in the gears.

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

When scanning x-rays, sounds like belt is sticking.

As the scanner will still be under warranty this is best directed at Umax support.

My scanner :makes a loud noise when trying to scan or copy

Unless you forgot and tried to use it locked…then unlocked it after, it seems unlikely that changing the ink could directly affect anything related to the scanner. So especially if it still scans and now just makes more noise then before, we can reasonably say it isn’t a faulty locking mechanism and that the gears are probably not stripped, which would either stop it or not. So you’re looking at either something simple like the gear assembly being dry, shifted slightly, etc. or the safety by the lock that makes noise to tell you the device is locked is stuck somehow. The one can be tested by removing the little plastic safety that makes the noise when the scanner is turned on and locked; the other you might be able to test with some WD40 and see if it runs quieter.

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.

Makes grinding noises, refuses to scan; WinXP

take a look on the underside of the scanner. there may be a switch that goes from lock to unlock. try to move it to lock and back into unlock. this lock is usually used to lock the bar from moving during shipping. if this got moved back to lock or bumped while you had it turned over, the scanner will not allow the bar to move.. try this first.
