other peripheral equipment, printer.

Figure 3-6 Removing the Head Cap and the Tape
Do not reuse a head cap and tape that have been removed once. If they
are reused, the head may be clogged with foreign matter, or colors of ink
may be mixed.
Peel off the tape protecting the nozzles without touching the print head.
Poor printing may be caused by scratches on the printhead or any foreign
object adhered to it.
After removing the cap and the tape, do not shake the BJ cartridge. Ink
could splatter out if you do.
