Cleaning the print cartridges Cleaning your print cartridges can improve the quality of printing. If your printed page is missing lines or dots, perform Procedure 1 below. If your printed page contains streaked ink, perform Procedure 2. Procedure 1: Correcting missing lines or dots Clean the print cartridges when you notice that the lines or dots are missing from your printed text and graphics, as shown in the left margin. The print cartridges can be cleaned from the HP Toolbox. Note: Do not clean the print cartridges unnecessarily, as this wastes ink and shortens the life of the print cartridge. To clean the print cartridges from the HP Toolbox: 1 Double-click the HP Toolbox icon on the computer screen. 2 Click the Printer Services tab. Note: MS-DOS users can clean print cartridges from the HP DeskJet Control Panel for MS-DOS. 3 Click Clean the print cartridges and follow the directions on the screen. If the preceding procedure does not improve the print quality, your print cartridges might be low on ink. Replace the print cartridges. Procedure 2: Eliminating ink streaks or sn ame jstujn de d diam noft juestk Customers using HP DeskJet printers in dusty ut labore qusft vol sed kitft ghocknor environments might occasionally experience ink streaks or smearing because of a small accumulation of debris inside the printer. This debris can include dust, hair, carpet, or clothing fibers. Ink streaking is easily prevented or corrected by doing scheduled cleaning to three areas of the printer: the print cartridges, the print cartridge cradle, and the service station. HP recommends that you perform this cleaning every 3 months. 37
