Problem on Toshiba e-studio45

Yes, it also happen when I copy and sometimes the whole paper becomes black. We clean the corona wire near the drum. After cleaning, the copy is okay but after only 5-10 copies especially on multiple copy the one-inch black or the whole paper is black returns.

    Thanks for the solution. We change the drum blade and the copy is alright. We just monitor the copier if the problem will return. Thanks a lot.

My Brother MFC-7420 Printer always prints black lines and splotches down the left side of my paper. This happens whether I'm scanning or printing from my PC. When I looked at my drum, it appears a


If you are seeing vertical streaks/black lines your primary corona wire is dirty and or the fax scanner may be dirty.
1)To clean the corona wire you take the drum unit and toner cartridge and place it on disposable paper to avoid spilling.
2) Clean the primary corona wire inside the drum unit by sliding the blue tab from right to left several times.
3) Return the blue tab and snap it into the home position.
4) Reinstall the drum unit and toner cartridge.
5) Close the front cover.
Caution: if you do not return the blue tab to the home position it may repeat the black lines.

Paper comes out black when printing and copying.


A. The drum is not being charged. The charger corona wire is probably broken or not making good electrical contact. The charger corona wire may be part of the toner cartridge. Try uninstalling and reinstalling the toner cartridge. If that doesn’t work, try another toner cartridge.

Blank copy


the charge corona assy. is just the silver assembly that the corona wire is inside of. to help verify where your problem is, lift up your top lid and make a "sky" shot. watch your lamp under glass, and when lamp gets about 5-7" from left, quickly open front door. now, open the copier to inspect the bottom side of your drum. if you see a good coating of toner on drum, but not on paper, the problem is in the corona assembly thats on the bottom, middle of copier directly under your drum. if no toner on drum, then its very possible its the charge corona assy. on top of your drum.

Problem on Toshiba e-studio45


Yes, that could give you dark copies on one side of the copies... I use a glass cleaner to clean of the primary charge roller or grid. wipe them off with out getting any thing on the OPC drum it self. Did you clean the optics already?

Problem with gear of Toshiba e-studio45


I beleive it is compasating for the drum, you can change the corona wires( it is not difficult, but there is a certain skill and dexterity to it) you can find the wires at Radio shack or Ace, I beleive.

I'm not sure of which gear you are refering to, please clarify. TNX

Gear easily worn out on Toshiba e-studio45


The dark copies could be that you need to clean your optics aswell, they are under the copy board glass. If the mirrors are dusty you will get alot of back groud in your copis and poor C.Q. I would just use a dry cloth to wipe the mirros off, should be three. Also, I would use a cloth with a little alchol on it to clean the lamp.. Almost forgot turn the copier OFF first. The small gear could be that there is another problem with the developing unit.... There may be a worn out bearing or seal... It should last longer.. Is this the second time it will need replacing? If so you may have to look alittle deeper

I'm sorry to tell you, this is likely a drum issue.

You probably need to have a certified engineer examine the machine.

Have you tried speaking with the local service center to see if they have experienced similar issues? It might be free information.
