Poor contact between the print cartridges and cartridge cradles might also affect the quality of
the printout. When this occurs, try cleaning the print cartridges and cartridge cradles:
1 Remove the print cartridge from the printer.
2 Clean the electrical contacts on the print cartridge cradle with a dry cotton swab.
3 Clean the electrical contacts on the print cartridge with a dry, lint-free cloth. To prevent
damage to the electrical contacts, you should wipe the contacts only once. Do not wipe
the ink nozzles on the print cartridge.
4 Reinstall the print cartridge.
Printing from MS-DOS software programs
When printing from MS-DOS®, you can adjust printer settings in two ways: in the HP Deskjet
Control Panel for DOS and from within your DOS application’s printer driver.
You have access to many printer features through application-specific DOS printer drivers;
however, some software manufacturers do not develop printer drivers for their DOS
applications. Use HP Deskjet Control Panel for DOS to specify the default printer settings for
printing from DOS applications.
