Gestetner 2722z copier, new drum, new transfer belt, smudges yet
I've replaced fuser roller and transfer belt, it has a new (100,000 copy)drum from last year with only 15,000 copies on it; yet I have a weak 'light' copy and grayish smudges along both sides of paper as it runs through; drum is clean and with new trasfer belt I can't figure (?); I have no manual to determine adjustments

Sounds like its a magenta drum going bad. It could also be the transfer cleaning blade assembly, or the transfer belt needing replacement. Do you know if any of these items have been replaced. Drums usually last around 40,000 prints. Transfer belts 300,000 and the blade 100,000. Hope this helps.
Just print 20 or 30 pages with nothing, or only a little dot or something. Your printer is polluted and needs to be cleaned. Sometimes it is enough just to run a few empty pages. If this isn't enough, look at your manual how to clean your drum and fusing unit.
The white line or lines are NOT caused by the fuser. A defect "line" in the fuser would cause the symtom of the print rubbing off the page but not blank lines on your copy. First we need to separate your copy quality issues. This machine uses 4 drums, 4 developer units and a transfer belt. Most copy quality issues will reside in 1 or more of these units. Lets start with a few questions. 1)Are your copy quality issues ONLY on color copies? or are the black and whites poor too? 2) Are you running copies only thru the document feeder or have you made any copies from the glass?
Are you printing on the copier from your computer?
Send a print from your PC or print out the Counter list from User tools/counter button.
Try printing one colour at a time - Black, Cyan, Yellow or Magenta.
If when printing, there is no line across the pages, so you need to clean the optics mirrors and exposure glass.
If the line appears in both 1 and 2 mentioned above, you have the fuser roller or drum damaged.
If the line appears in all colour prints, check the fuser or transfer belt.
If it happens only with one particular colour, check that drum unit.
*** NOTE*** does machine have an ADF (auto document feeder)? Are you
feeding the paper through the ADF to make copy? IF machine has ADF and
you get the lines from that, place original on the glass and make copy.
Does the copy have the lines? If so continue. If not lines then clean
the '**** glass' ( thin small glass that the original is pulled over in
the copy/scan process. This is under the ADF.
Next, if problem not rectived, it depends on how the paper is fed ( comes out of the machine). Let us say that the paper cover out of the machine 'letter' or ' portrait' and you look at the copy --- the lines are from left to right on the copy, okay. These lines could be from the fuser ( the hot area), pull the fuser out and look at the fuser rollers. Do the fuser rollers have lines -- if so then the rollers need to be replaced. If not then you are looking at the drum / transfer unit. Probably a blade is bad and will need replaced. To tell whether it is drum or transfer -- start to make a copy and open the front cover as to stop the paper in mid-stream. This way you can tell which unit has the problem. NOW -- lets us say that the paper is coming out 'letter' again but the lines are from Top to Bottom. You will also want to look at the drum and/ or transfer units. This would but a 'stall' or 'blade skip' problem. Again, start to make a copy and open cover in mid-stream to see which unit has the problem.
If the drum unit is the problem, replace blade and maybe drum. IF the transfer unit is bad, replace transfer blade, roller and maybe the transfer belt ( if belt is present). Some transfer units use belts and other rollers.
Tell him you want the drum and the developer replaced only. A lot of the cost is going into the transfer belt. Usually our shop rebuilds them. It sounds to me like it's the whole assembly and not just the belt.
It sounds to me like the copier tech is giving you a worst case scenario price.
