16 | Introduction
Do not dismantle the ink cartridges or try to refill them. This could
•
result in damage to the print head.
Install the ink cartridge immediately after you remove it from its
•
package. Leaving the cartridge unpacked for a long time before use may
result in reduced print quality.
Do not use an ink cartridge beyond the date printed on the cartridge
•
package. For best results, use cartridges within six months of installation.
