If your copies continue to come out too light, you may need to clean the insert a new toner cartridge or change brands of toner. I tried several "generic" toner cartridges and refills, but my prints and copies were always faded or streaky. After going back to genuine HP cartridges, I haven't had any print quality problems.

Most often on the PC940 this means your toner cartridge is getting low on toner. To prove this is the cause, just remove the toner cartridge and while keeping it relatively level, shake it side to side a few times. This will re-distribute the remaining toner in the cartridge. Re-install and make a copy. The black streak/faded copy should be much better. If so then I would go ahead and get a new cartridge on the way.

The partial faint copy in your case is most likely toner on the laser optics. It is NOT the fuser.
Since you are indicating a toner dusting or spillage issue into the bottom or perhaps paper tray area then this toner is also most likely on the laser optics. This blocks a portion of the laser light and results in a faded or sometimes even blank portion of the copies. Dis-assembly of a portion of the machine is going to be required to clean the laser.
It is located between the toner cartridge and the Drum/PCU unit at the bottom of the machine. So if you open the front door where the toner cartridge comes out. The laser strip glass would be below and to the right of there the toner is. Some of these still have a small metal cover/clip that you can remove and then slide the laser strip glass out and clean it then re-install.
Hope this helps. If this makes no sense or does not help then it might be a good idea to call a service company and have the machine cleaned.
Good Luck and Thank You for using Fixya.

This is normally the corrona wire that needs to be replaced in the transfer unit and drum unit.

When you changed the toner did you remove the strip on the new toner to release the toner

There are two service codes that you need to run 2801 and 2805 after you put the developer in the machine.

Press the yellow button on the copier. press 107 on the keyboard. Press and hold the clear button. Then run the service codes.

You have to run the codes first after changing the developer. You might have to replace the developer again to get the correct mixture.

How old is your Toshiba copier?

It is the developer. All colours should be changed at the same time. This can be accessed via the right hand side of the machine, when you remove the cover. (where the output tray is)
