10.8 Removing ink from skin and clothing
Follow these instructions to remove ink from 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.
10.9 Maintaining print cartridges
The following tips will help maintain HP print cartridges and ensure consistent print
quality:
• Keep all print cartridges in their sealed packages until they are needed. Print
cartridges should be stored at room temperature (15 to 35 degrees C or 59 to
95 degrees F).
• Do not remove the plastic tape covering the ink nozzles until you are ready to
install the print cartridge in the printer. If the plastic tape has been removed
from the print cartridge, do not attempt to reattach it. Reattaching the tape
damages the print cartridge.
Storing print cartridges
When print cartridges are removed from the printer, store them in a print cartridge
protector or an airtight plastic container.
If a print cartridge protector came with the photo print cartridge or the gray photo
print cartridge, use the protector to store the print cartridge. If you store the print
cartridge in an airtight plastic container, make sure that the ink nozzles face down
but are not in contact with the container.
Inserting the print cartridge into the print cartridge protector
Slide the print cartridge at a slight angle into the protector, and snap it securely in
place.
