If its a solid line check the drum and fuser rollers. If the drum doesn't look like there is wear on it look at the fuser. If you can see a groove in the fuser heat roller or any tearing in the pressure roller replace them. As far as cleaning goes on these machines, rubbing alcohol and a rag. Dont put the alcohol on the drum tho.

If the line isn't solid and appears interminently on the pages then clean the charge corona. Hope this helps.

I hope this image here helps clarify things a little. I know its not a good image but its best i can do with what i had at the time.

Clean your drum and DCB Assym. If it goes away and comes back then replace the drum and dcb.

getting blank copys

after cleaning out the parts now im getting blank copys..seems like the ink doesnt want to feed into the drum.

Are you sure you hooked in the charge corona properly? If that wire assym isn't plugged in properly it will effect your picture quality.

Make a dark copy and adjust the exposure blinds to make the grey background uniform. Plus try cleaning the charge grid with alcohol.

I just had a machine do this problem to me last week. Ordered a drum, dcb, and corona unit. Installed them and it went away. With old machines like this you can never tell if the part itself is bad so just replacing them is best off.

ok take out the drum unit and look inside the machine you will see a slit glass which is just in front of the dev unit clean the slit glass with metho and the under side of the main glass with metho and all the mirros with metho and then the top of the glass with mr sheen or furniture polish see how that go's

Start with a basic service 1st

optics ( dont 4get the 1's under the lens cover - 4 skrews)
remove glass dust shield (located above the drum behind main front cover)

try adusting the metal plates which r located above the scan lamp
make sure the morros are aligned correctly and not skewed

check F5-25 change to 0

adjust f6-11 exposure adustment
f6- 19 bias adjustment

if the dirty mark/line is lead edge try the following

r u finding toner on the transfer? if so check catch blade below drum blade
remove the dev unit - place dev unit over a sheet of paper and rotate dev roller by hand, check for deposits of toner on the paper, replace dev if it does
