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.
