Ink Maintenance
You can clean any printer’s exterior with a damp cloth, but interior cleaning differs for inkjet and laser printers. For inkjets, open the ink-cartridge access panel and use a dry cloth or chamois cleaning swabs to remove any dust or ink. Then run your printer’s head-cleaning software to clear the ink nozzle. For laser printers, remove the toner cartridge and wipe the toner cavity and rollers with a dry cloth, while avoiding the transfer roller that sits directly under the cartridge. Resist the urge to clean the optical mirror near the toner cavity; you’ll only distort it.
