PIXMA PRO series printers: power off safely

When unplugging a PIXMA PRO series printer, don’t simply pull the plug out of the back of the printer. First make sure you have turned the printer off by pressing the ON button and waiting for the power lamp to go off. It may seem like it should make no difference, but if you unplug the printer without turning it off properly, you may cause ink to dry on the print head and clog the jets thereby reducing the print quality in the future.
