The LaserJet family of printers by Hewlett Packard is a fairly common printer model in homes and offices. Like all printers, they occasionally require cleaning—both inside and out. Unlike ink-jet and dot-matrix printers, however, cleaning these laser printers is not as simple as pressing a “Clean Ink” button on the printer’s main panel. Rather, a special utility must be downloaded from the manufacturer’s website to properly clean the printer. It’s a good idea to clean the printer about once a month, or when it begins to show signs of a dirty print head. These signs include ink filling in the spaces in letters, and faint lines appearing in the margins of printed pages. Clean the printer more often if it receives heavy use.
