The dark copies still return. I have already change the drum and drum blade. I inspect the primary and there is a soot or toner on one side of the primary, is these alright or there is a problem on these part.

Re: 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?

Hello, first the paper can be dirty in a lot of ways...
If you have dark "background"or small black dots, the problem is in developer and it need's to be replaced, or cleaning blade or drum. If you have streaks on copy, the problem can be in drum and cleaning blade or fixing roller. If the copy is too light, the problem can be in dirty optics or bad transfer corona.
There can be a lot of things... better call service for preventive maintenace, they will change all that is needed according the number of copies that machine has.
This is for a Mita 1560 Photocopier (analog)
J50 was caused by exit sensor not sitting correctly in its bracket,I fixed this by pushing it until it
clicked back in.
The dark lines & double imaging can be caused light getting onto the drum ,or if the drum gets
cold (so I have been advised) which one it was for sure I will never know because when I
returned the next day & fixed the exit sensor the copy was OK.
Have you had the optics cleaned resently? If not Iwould start with that and make sure you have the copier unpluged and don't forget to clean the two mirrors under the Black Box/cover. It could also,mean that you need a new OPC drum and blade.. It depends on how maiy copies are on the copier and drum...
I beleive that if there is a problem with the primary you will only get a blank copy not black.
the problem is most likely your Seperation ***'y or the drum.
1- either the sep/***'y is shorting out causing the paper to rise against the drum and putting too much toner output, or the drum has not been adjusted correctly. Did the tech adjust the new drum to the machine? there is a procedure you have to do everytime you change the drum.
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
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
bit vague...Cq not good? What does that mean? Light copies> could be related to toner or ROS unit (laser unit) if prints OK but copies U/S clean mirrors and ccd lens Dark copies , streaking? Cleaning blade /drum unit U/S or could be streaking from fuser roll Patchy copies , dark edges, light edges ??????? more detail please
