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

Put paper in the manual feed tray(tray 1). Print something. When the paper gets about 1/2 way into the printer, open the top cover. Pull out the toner. Look down at the paper in the printer. Do you see a thick dark line? Replace the toner. No thick dark line, check the fuser for damage.

This is just a printer, not a copier.
Thank you,

Solved

You cannot COPY with just a printer. You'll need a SCANNER too. Basically, you use the scanner to scan the page, then you print it using your printer.

This is probably due to a defective cartridge, Charge Roller or Transfer roller.

Check the cartridge for a band of toner still on the drum.

Check the Charge roller for oil or smudges, this roller should be a lighter color and should be relatively free of toner or marks.

Same as the Transfer Roll, which will be dark, though excess toner should be evident.

A relatively smooth straight line is generally the cartridge.

A rather wavey or broken line is most likely the rollers.

You can however attempt to print a large amount of pages (25-50) in an attempt to clean the parts, however if either part is defective they will need to be replaced and no manner of printing will clean them.

Does this happen both when copying and printing?
For printing solution, try another toner cartridge.
If lines continue to appear when copying (primarily through the automatic feeder) then lift the auto feeder, and clean the glass -mainly the narrow piece on the left side.

please rate solution :)

Maybe your transfer belt is damaged. If u have an spare belt replace it for a test. Answer me if it dont work. Maybe i can get an support manual for u. I work in a HP partner company.

Good luck

Is the driver installed? Do you see it in the printer section/
?

On the 5p printer there is a button.
when you hit it does it print?
