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!

Hello,

Enter in service mode and do an cartridge adjustment. Maybe the toner is not uniformly distributed in cartridge. Also you can search on internet for service manual, this may help you a lot.

Toshiba 2060 Photocopier prints copies that are a bit too dark.


restart the copier while holding down the "0" and "5" keys. you will now be in service mode. enter "5" and press "start" key a number should show up in the display. this is the exposure value - how dark or light the copies will be. 5 is the automatic exposure setting. around 128 is the normal value. the larger this value the lighter the copies are - the smaller the value the darker the copies.
Enter a new number (exposure value) and press the "interupt" key to save the value. Restart the copier and check what the copies look like. Keep adjusting until it looks good/better.

Hello Bob,
Where are you located? You should be able to find the toner for this machine. Have you tried www.precisionroller.com ?
I am almost positive that they carry the toner and also consumable part as well as replacement parts.
One of the reasons the copies might be dirty, is that the optics, charge wires, cleaning blade, drum, and or fuser unit might need some parts replaced. Without seeing a copy of what the machine is actually doing, or looking at the machine, it's hard to pin point exactly what is going on.
If you have any questions with the machine, feel free to post any questions and I will be glad to help you.
Good luck.
Hope this helps.
Mac =)
