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 on the left. 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.

NOTE DOS users can clean the print cartridges from the HP DeskJet Control Panel for DOS. Refer to “Printing from DOS” on page 56 for details.
