1. Using your printer regularly is the best way to maintain consistent print quality. Clean your print head if you haven't printed anything for some time.
2. Always use your printer's power switch to shut off your printer. Powering down any other way can park your printhead improperly, making it vulnerable to drying out.
3. Remove, shake gently, and replace toner cartridges that seem to be running out of toner. You might get additional pages or jobs.
4. When printing from the Web, turn off images in your browser. Select "printable view" whenever possible.
5. Save time and toner by choosing "draft" or "economy" mode when you don't need best-quality printouts.
