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.
If it is vertical line then it indicate an almost empty or faulty toner cartridge or some spilled toner inside the printer.
if you require further help feel free to ask
mention your model no
how old is your printer ?
Thanks for using Fixya
