Lines down left side of paper

I forget the terminology but I believe there's either dirt or a sheet of paper on an internal roller.

You might try here for HP help.

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.

It could be 2 things...

1. Your scanner glass is dirty...open the doc feeder and clean the glass. probably Wite-Out.

2. A segment of your scanner assembly lamp is burned out. Not good, uneconomical to repair.

Try running its Clean Cartridges command.

...maybe its time to replace fuser fixing film!?

Pull out the toner cartidge, lift the flap and look at the drum, it should be clean. you will have to buy a new cart to fix

It sounds like your having a fuser issue. Look at the lower rear side of the machine for the door. Remove the door by pressing in on the lower left tab. Remove the fuser to view the rollers. If the rollers have melted toner on them, that's your problem.

Hope that helps ya.

Check your Toner Carts.
Is the line a certain color?
Black perhaps?

Lift the door of the toner cart.
If you see a streak on your toner drum, you will see a streak on your paperwork.

Look at your fuser as well.
Is there a problem with the big orange roller?
BEWARE! Don't touch the fuser roller its EXTREMELY HOT!
Let the printer cool down before inspecting.

take out cartridge, look at he inside of machineis there toner on the left side of a thin glass, look at the fuser ( where it gets hot) are the rollers O.K. ?
