Purchased this printer from craigslist n was told it worked fine, however each print and or copy is missing toner every few inches, which creates a white line pattern and obviously missing information. The printer may have been stored for some time, I do not know. Seller claims it saw "little use". I am reluctant to purchase new toner or a new drum without knowing which is defective --- any help ? Does something perhaps need cleaned ?
The drum is light sensitive and if one side was exposed to sunlight for as little as 20 seconds could have that effect , it is at best a shot in the dark (no pun intended)
SOURCE: LEAVES A BLANK LINE DOWN THE COPY
Dear sir; Try to pullout the drum unit, see have anything block the scan path( such as paper chip) or check the heat roller is there have torn paper wind up.
SOURCE: vertical strip of black lines on copy
PULL THE INK CARTRIDGES OUT AND VERY GENTLY WIPE THE CIRCUIT BOARDS LOCATED ON THE BOTTOM WITH A VERY SOFT CLOTH ....THEN GO THRU THE CLEAN UP MODE IN THE OPTIONS .
SOURCE: Faint red line across page when making color copies or printing in color from computer
Some possibilities are:
1) Dirt on the glass, dirt on the glass strip for the doc feeder, or dust on the mirrors. This would be the case if the line only showed when copying and not printing.
2) Toner dropped onto the charge sawtooth.
This may be possible if the line is intermittent and only showed up for 1 or 2 colors.
Open the front door and remove the waste toner box. To the left of each drum there is a green organ-stop type stem. Pull and reinsert each stem. You will hear a zipping noise. These are your charge scrubbers.
This may be not as likely if the line shows up in the same place on all 4 colors
3) Toner or dust on the lens
This may be possible if the line is intermittent and only showed up for 1 or 2 colors.
In the area where the waste toner box goes, look for a grey stick with a white cushion on the end. This is your lens scrubber. Look in the area under the charge scrubber on each drum cartridge for a gap. Insert the scrubber cushion side down into the gap and run it forward and back to clean the lens.
This may be not as likely if the line shows up in the same place on all 4 colors
4) Transfer belt blade not cleaning
This is best handled by a service tech since the mylar belt is very fragile. The squeegee blade that cleans the transfer belt between copies is missing a spot. The blade needs to be taken off the belt, cleaned and repowdered. Recently, Sharp made changes to the composition and thickness of the mylar in the transfer belts. Overpowdering the blade or belt when it was changed may cause improper cleaning of the belt creating lines across the copies. Often the condition clears up after a couple of days as the gap between the blade and belt is sealed.
This is most likely the cause as the line shows up in the same area for more than 1 color.
5) Transfer belt and/or blade is worn out
If the belt is worn the blade must be replaced but not vice versa.
6) Clogged waste augers in the drum cartridges.
Waste toner may cake up in the drum cartridge and knock loose on the drum.
It may be time for full maintenance on the machine.

Start a print or copy, and just as the trailing edge of paper is entering the machine; quickly open it to stop print and take out the cartridge and look at the drum and the paper underneath. If the issue is there at that point then it would point to the cartridge. If not then it is in the fuser area.
Clean the loose toner up with a dry lint free cloth.
