Vertical lines printed on right side of every page
This printer has been nothing but trouble. It is less than 1 year old and has printed very few pages. Now all pages come out with 2 vertical lines on right side of page. I have replaced toner cartridges. I examined the drum and see marks that appear to line up with the lines. What would cause this and what is the fix? I see posts about replacing the drum, but my drum is not near old enough.
Re: vertical lines printed on right side of every page
Would be helpful to know the brand and model of the printer. Sometimes this is caused by not returning the slide used to clean the primary corona wire to its original position (usually to the extreme left side of the toner cartridge) after cleaning the corona wire. If you haven't cleaned the corona wire, you should follow instructions and do that first.

If the lines go all the way down the page, check the position of the corona wire cleaner tab (blue or green) at the top front of the drum unit. if not parked fully to one side it will create a solid black lines where it blocks the laser. Otherwise look for some other foreign object (or torn paper piece) that may be blocking the laser from the drum. If the lines are thin and shark, check for scratches on the drum (not repairable without replacing drum). If the lines are uneven thickness but in a pattern that repeats down the page every few inches, then the film on the drum is probably worn or wearing away and the drum needs to be replaced.
Printing not dark enough or varied in darkness If the print is a dismal gray rather than a sharp black, you are
probably almost out of toner. This can manifest itself evenly across the
entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by
taking it out and gently shaking it from side to side (never up and down,
as toner can spill out). You can also try turning up the printer’s
contrast adjustment, if it has such a knob (usually on the back side if it
exists). Faded print can also result from a dirty corona wire, because a
dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to
frequently remove the toner cartridge and shake it to redistribute the
toner inside it, make sure the printer is sitting on an even, flat
Horizontal black lines A horizontal black line on the printout is probably the result of a
dirty or damaged roller. There are lots of rollers in the printer, and you
can use the space between the lines on the page to determine which roller
is causing the problem. Measure the distance between the errant black
lines on the page and then use Table A to determine which part
might be causing the problem.

Regularly spaced splotches If there are evenly spaced black spots but they don’t extend all the
way across the page, the problem is probably a scratch or flaw in the drum
or a build-up of toner on the fusing roller. If the spots are less than
three inches apart vertically, it’s probably the drum, because the drum
has a larger diameter than the fusing roller.
Vertical black line on edge of page This can indicate an almost empty or faulty toner cartridge or (less
frequently) some spilled toner inside the printer.
I would be calling Lexmark about this because this is not a user serviceable issue. If you are down to measuring the size of boxes that it prints out and they are not right, I would want to see what the issue is and how to fix it.
try the toner cartridge. You can see where its coming from by printing 1 page. When the page starts coming out of the machine open the cover. Take out the toner cartridge and look at the page. The line should be there and you should be able to figure whats causing it. It's almost always the toner cartridge. If you have an old cartridge put it in and run a test with it. If the line is gone its the cartridge.
