Is the problem only with copies? Does the machine also print light?
If is it copy only, remove the glass and clean the lamp and mirrors in the scanner.
If it is both copy and print, then you should clean the laser shield glass and replace the developer.

Produces Light Copies


Have you considered changing or checking the toner cartridge?
Does it display a low toner light?

I had a similar problem with a copy machine, where ALL the settings were correct and the toner was light.

The problem was the toner cartridge, the toner was caking because of the temperature. All it took was a good shake at the toner cartridge and it worked.

Also, check to see if the scan bed is messy, a good cleaning the the scanner bed should work as well.

Hope That helps!

Our nonprofit got a sharp sf-2040 donated. It prints a too light of a copy. I tried to replace toner it was full. No keys or directions light up - does it need a new drum or something.....??


There are several solutions to this problem:
1. Adjust the exposure
2. The drum may be out.
3. The developer may be out.
4. Finally, You may need a PM for the copier. (replace the drum, developer, drum blade)

Added toner/copies still too light


adding toner to Canon copiers will not fix copy Quality problems. Do the copies look better if you manually adjust your exposure setting? If so you can clean the optics, which are the mirrors under the glass. Be very careful there are alot of sharp metal edges, that can cut you very easily.
You can use windex.
