Try another toner cartridge. If that doesn't solve it, then the fuser is failing.

I have a grey/black line all the way down the right hand side of the page


Run a half test.
Put paper in the manual feed tray.
Print something, anything
When the paper is 1/2 way into the printer, open the cover.
Pull out the toner cartridge. Look down at the paper.
Does it have a black line on the right side?
If yes, replace the cartridge. If no, replace the fuser.

Black line is present when copying document; not


This sounds as if you have some ink/contamination on the small scaning glass that sits to either the left or right of the main glass on the copier.(Depending on the model/make)As your original is scanned over this thin piece of glass the scanning device will see any spots and this will result in a black line down the page.Please clean the glass with a soft rag.

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

Hi there check that it isn't the drum unit by turning the machine off open the top cover remove the toner and underneath you will have the dev unit unplug and lift out then remove the transfer tray (the one you open if there is a jam) open side door remove waste tank then you have the drum unit now to remove there is either a push button or a screw do either one that corresponds and check the unit. If there is a black line on one side the only way to get rid of the line is to replace the cleaning blade as this has worn. you can clean the drum unit cleaning blade it may only be toner stuck under the blade all you have to do is rotate the drum the opposite way of operation and if you have to hand a air line just give it a blast failing this it will defently need replacing.

Hope this is of some help
Please rate me

Colors faded on left side of paper black and blue


Is it possible for you to clean the printheads manually with cotton buds and cleaning solution on this unit. Clean all thoroughly and this might just correct issue.
