HP Deskjet D1420 Printer - Manual (Page 53)

NOTE: If the print cartridges were used before being installed in the printer, or if they
are not genuine HP cartridges or have been refilled, the estimated ink levels will not
appear on the Estimated Ink Level tab.
The Estimated Ink Level tab also contains print cartridge ordering information. To view
this information, click the Print Cartridge Information button.
NOTE: Ink from the cartridges is used in the printing process in a number of different
ways, including in the initialization process, which prepares the device and cartridges
for printing, and in printhead servicing, which keeps print nozzles clear and ink flowing
smoothly. In addition, some residual ink is left in the cartridge after it is used. For more
information see

Maintain the printer body
Because the HP Deskjet ejects ink onto the paper in a fine mist, ink smudges will
eventually appear.
To remove smudges, stains, or dried ink from the exterior
1. Turn off the HP Deskjet, and then disconnect the power cord.
2. Wipe the outside of the HP Deskjet with a soft cloth that has been lightly moistened
with water.
CAUTION: Do not use any type of cleaning solution. Household cleaners and
detergents might damage the printer finish. Keep all fluids away from the interior. Do
not lubricate the metal rod on which the print cartridge cradle slides. Noise is normal
when the cradle moves back and forth.
Remove ink from your skin and clothing
Follow these instructions to remove ink from your skin and clothing:
Surface Remedy
Skin Wash the area with an abrasive soap.
White fabric Wash the fabric in cold water and use chlorine bleach.
Color fabric Wash the fabric in cold water and use sudsy ammonia.
CAUTION: Always use cold water to remove ink from fabric. Warm or hot water can
set the ink into the fabric.
Manually clean print cartridges
If the HP Deskjet is used in a dusty environment, a small amount of debris can accumulate
on the print cartridge contacts. This debris can cause ink streaks on printed pages. The
problem can be corrected by manually cleaning the print cartridge contacts.
