Why do my printed pages have lines?

Episode 1472 (1:35:32)

Peter from San Gabriel, CA
Brother laser printer

Peter wants to know why his printed color pages have lines in them. Leo says that if he doesn't print a lot with an inkjet printer, lines will occur because the ink simply dries up in the print head. He'll need to run the ink check/self cleaning utility on the printer to clean the printer head. The downside is that will use up a lot of ink. That's why Leo says that inkjet printers really aren't a good idea for people who print seldomly. A laser printer is better because it uses a dry toner. The downside is that laser printers aren't good for printing pictures, so he'll have to go to a photo store for that.
