Black shade in copy - Toshiba 2060 Copier

scanning mirror problem.

photoconductor unit is a drun unit which does the actual copying of image on the paper. its life is 60,000 copies. its will need a replacement because after a while you will notice there are black marks appearing on your copies or your copies are not good or black shades. photoconductour unit is just beside toner supply unit. you can pull out the whole unit.

hi dude i dont think u have problem with drum cleaning blade coz it not making trouble for me from last 5years.
just replace the crona wires both charge and transfer and clean the whole scanner mirors .
thanks

3 possible causes:
1) The optics are dirty thus making your copy darker. The test for this is to manually lighten the copy using the exposure control on the panel of your copier. Lighten the copy several positions and see if the copy gets better. If it does then the optics need to be cleaned.
2) The copier is overtoned. This means that the toner to developer concentration is to high. This will require a trained technician to lower the toner ratio and then recalibrate the toner/developer ration using the F8 mode.
3) If the shading gets much worse as you run say 10 copies in a row then the drum cleaning blade would be the cause. So run 10 copies of something and compare the first copy out with the tenth copy out. Do you see a dramatic difference in the amount of background or "shading"?
Good Luck and thank you for using Fixya.

Most common cause is a dirty corona wire and or drum. If after cleaning the corona wire and drum the copies are still mostly black and smeared, the drum may be broken. Best of luck.

Call Kodak for a new printhead.

If the lines look like little steps, maybe broken is segments off by about the thickness of a pencil line, try this. Most likely it's the scanner. You can try calabrating it by doing the following. press in order. Menu #1934. You will see a T pop up to the right side of "Ready to Copy". Then press machine status, then scroll until you find maintenance. May be under system settings. When you find maintenance, press enter, then scroll to Shading Adjustment. Or depending on software version, Adjust shading. Place 5 sheets of paper on the glass,, press enter, then when is says "Adjust Shading?" press enter again. Let it print out the sheet. Then try a copy. If that doesn't help, the scanner itself will probably need replacing.
The scanner is the issue. The segments of what is called the CCD are not working properly.
Once you adjust shading, if that doesn't work, the scanner will need to be replaced.

Sounds like the drum is worn out. Usually do 60-70K before replacement. Shading more noticeable at top of copy. Could also before worn upper fuser roller.

Dark shades on both side of the paper? Drum cleaning blade or fuser assembly. Check the upper fuser roller and the drum for build up.
