Try turning off the potential controller. Or push the primary wires closer to the drum .5mm. Could be a potential control problem.

    One more thing...there is a dustproof glass that is located to the right of the charge corona and can be pulled out from the front. On old 6050s these can get filthy and cause very light copies. Pull it out and check and clean if necessary. If it's really dirty you will notice a big improvement in c.q.

If you have changed all you mentioned with the correct parts, I can only advice you to change the control board.

Try to warm your papers
The same power you are using now, is it the same you have been using before facing this light copy problem?

Hi i have problem with my copier its copy page is totaly black new toner replaced but didnt use for about n year please advice thank u


It would be best for you to have the machine serviced as you have not used it for a year. the issue you have could be the main charge corona unit that sits above the drum is broken you will need to check the corona wire also check to see if the exposure lamp is coming on it could be the exposure lamp or scan harness

Why are my copies coming out solid black, even though my exposure lamp is still working?


A couple of possibilities. Basically if your exposure lamp is coming on, the light is not getting all the way to the drum that is in the toner cartridge. It could be you have a mirror out of place. When the exposure lamp comes on, the light is reflected off the original and then off a series of mirrors until it gets to the drum. If one of the mirrirs has been knocked out of place, like due to a recent cleaning then that would cause black copies. The more common cause would be the drum protection "gate" that is on top of the toner cartridge is closed and thus blocking any light from getting to the drum. You can slide out the toner cartridge and look on top. There is a gate or panel that flips open to be able to see the drum. This gate must be opened when installing the toner. Also it is possible to have a bad cartridge but that rarely causes completely black copies.
Good Luck and Thank You for using Fixya.

Changed the toner now I am getting black copies?


It's important to gently shake toner cartridge from side to side to distribute the toner. It's also important to clean the corona wire (by sliding the tab from side to side) and the drum each time you change the toner cartridge. You should remove the toner cartridge (be careful, it can be messy), clean the corona wire and drum and your copies should return to normal.

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.

Corona wire


I was getting the clean the corona wire problem message even after repeated cleanings.  Before this problem occured the toner light was flashing warning of low toner. When I got the clean the wire pop up the toner light was on all the time indicating the toner was depleated.  So, I thought I would try replacing the toner cartridge and see what happened. I opened the new toner box and noticed on the foil packege specific instructions to clean the corona wire when installing the new toner.  I installed the new toner and cleaned the wire one more time. I then reinstalled the drum and toner assembly into the printer and the clean the corona wire message did not come up again.  The printer now works fine.

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.
