6 Care and maintenance
The printer requires very little maintenance. Follow the guidelines in this chapter to
extend the life span of the printer and printing supplies, and to ensure that the photos
you print are always of the highest quality.
Updating printer software
Download the latest printer software updates every couple of months to ensure you
have the latest features and improvements. For more information, see the onscreen
HP Photosmart Printer Help.
Cleaning and maintaining the printer
Keep the printer and print cartridges clean and well-maintained using the simple
procedures in this section.
Cleaning the exterior of the printer
1. Turn off the printer, then disconnect the power cord from the back of the printer.
2. Wipe the outside of the printer with a soft cloth that has been lightly moistened
with water.
Caution 1 Do not use any type of cleaning solution. Household cleaners and
detergents may damage the printer finish.
Caution 2 Do not clean the interior of the printer. Keep all fluids away from
the interior.
Caution 3 Do not lubricate the metal rod on which the print cartridge cradle
slides. Noise is normal when the print cartridge cradle moves back and forth.
Cleaning the print cartridges
If you notice white lines or single-color streaks on the photos you print, the print
cartridges might need to be cleaned. You can run an automatic cartridge cleaning
procedure using the software that came with the printer. For more information, see the
HP Photosmart Printer Help.
If you complete all three levels of the automatic cartridge cleaning procedure and still
see white streaks or missing colors on the test page, you may need to manually clean
the print cartridge contacts. For more information, see the following section.
Note If the cartridge or printer has been recently dropped, you may also see
white streaks or missing colors in your prints. This problem is temporary and
clears up within 24 hours.
