You need to clean your inkjet cartridge nozzles about once every three months or whenever the output from your printer suddenly starts streaking. You don’t need a scrub brush to clean your printer cartridges; instead, your printer can take care of cleaning its own cartridges (with your approval, of course). You can probably access your printer’s cartridge-cleaning controls in its Properties dialog box:
Choose Start→Printers and Faxes to see the available printers on your system.
Or choose Start→Settings→Printers and Faxes, depending on how your Start menu is configured.
Right-click the printer you want to calibrate and then choose Properties from the pop-up menu that appears.
The printer’s Properties dialog box appears.
Locate the printer’s cleaning options.
You might have to search the tabs (or check your printer’s manual).
Click the appropriate cleaning button.
Your printer cleans the ink nozzles, hopefully giving you perfectly printed pages again.
