You attempt to print a document. When you retrieve the page, you notice vertical lines running down the paper. Which of the following actions is MOST likely to resolve this issue?
Replace the fuser
Change the paper
Run the printer's cleaning procedure
Update the printer driver
Vertical lines or streaks usually occur when ink or toner residue clogs the print head (inkjet) or contaminates the drum/corona wire (laser). Most printers have a built-in maintenance or cleaning cycle that clears the residue and restores print quality. Replacing the fuser, changing paper, or updating the driver will not typically correct this specific symptom.
