Smearing Prints

Got a call from a woman said that her laser printer was having problems: the bottom half of her printed sheets were coming out blurry.

It seemed strange that the printer was smearing only the bottom half. I walked her through the basics, then went over and printed out a test sheet.

It printed fine. I asked her to print a sheet, so she sent a job to
the printer.

As the paper started coming out, she yanked it out and showed it to me. I told her to wait until the paper came out on its own. Problem solved.
