   You may have a clogged print head, a problem that can occur if you use an inkjet printer infrequently. Your printer's utility program can clean out the dried ink, and print a test page for inspection. The step-by-step instructions on how to do this vary by printer. From the Windows 7 Start menu, click Devices and Printers or Control Panel, and look for your printer's utility app. For additional details, read "Solve Inkjet Printer Problems."
