Hi folks,

I have an HP LaserJet 4250n that's putting vertical light black smudges (not a great word for them.. they're pretty uniform) down the center of most pages. It's all the way down, but it breaks at certain points and picks back up again. I've tried replacing the toner cartridge and cleaning the rollers.

Any ideas?

Check the printer manual from the hp site & see if it has corona wires.
If it does, clean them.
In the beginning there was the command line.
