When you say changed cartridge. Do you mean toner? It's much more likely the drum that's causing the problem.

I have dark lines all the way down on the left side of paper. I replaced the toner cartridge, and still having the problem.

It seems that the fuser film roller is damage and need to be replace. Only tecnichian can fix the problem because they will open the whole printer.Fuser film roller is color orange that u can see through. It is quite damage due to high volume of printing and this fuser film roller start to tear up from sideways. Or the black fuser roller is damage. Just try to clean this with alcohol and see if it works.

Black line going down side of paper from HP laserjet 1018

Roller Drum Problem in the cartridge.

If you are printing bulky document it may damage the roller drum causing dark line starting for both left and right paper. It will get bigger once it span of time.

Or if you are refilling the toner of the catridge, the waste compartment is full and requires to remove the waste tones inside the cartridge.

Or the worst thing is the the FUSER FILM ROLLER (orange plastic roller inside the printer is torn or burn because of heat or bulky printing.

Marks down left side of copy

There are several things that could be causing this I will TRY to address or suggest on all of them.

1.) If only appears when copying, double check the glass and make sure those areas are cleaned.

2.) If happens at all times, it could be the toner cartridge in the unit (especially if started when just changed). I would try another cartridge (later if you can stand the copies w/ the lines or if you have a spare).

3.) I have seen a lot of these machines do this putting vertical lines down the side of the paper because the fuser assembly has worn out and needs replaced.

I have seen #3 occur sometimes when paper gets jammed in a machine and someone pulls it out too rough, this can cause the slick cover over the fuser to crack, break, or bunch up, needing replaced.

Hope this helps you.

Our printer makes three dark marks on left side of printer. We have replaced the roller once and we still have the three dark marks on left. it is getting worse every day

Did you replace the toner cartridge or the imagine drum? My bet is you have only change the toner cartridge. The drum unit will require changing from time to time as well. It is likely that drum is worn out in that spot.

My HP LaserJet 5P printer has a dark line down the left side of the printed copies.

Most likely is the fuser but you need to know at what point the line is being placed on the paper which will require you to do some testing. You need to do a test page and then shut the power off to the printer when the paper is appoximately half way thru. Then open the lid and remove the cartridge. Look at where the toner is applied to the paper under the cartridge up until before entering the fuser (DO NOT TOUCH THE FUSER VERY HOT WILL CAUSE SERIOUS BURN), do you see the line? Or does the line start after exiting the fuser? If the later then you need a fuser.
