Basic Use
Replacing the Printhead
Replace the printhead if running Head Cleaning B twice
does not restore acceptable print quality, or if a customer
service center instructs you to replace the printhead. You
can easily stain your hands during printhead replacement,
so wear the plastic gloves provided in the box with the new
printhead.
Printhead BC-1350
Note
If the ink level is low, procure a new ink tank for
replacement as soon as possible.
Printhead Handling Precautions
Always follow these precautions when handling the
printhead.
Caution
Always store the printhead in a safe location where it is
out of the reach of small children. If a child licks or
ingests ink accidentally, seek medical assistance
immediately.
Never touch the printhead immediately after printing
has stopped. The printhead becomes extremely hot
during printing and can cause minor burns.
Important
Try to avoid dropping or shaking the printhead. Spilled
ink can stain the surrounding area.
The ink supply port of a removed printhead may be
covered with ink. Always handle the printhead
carefully. The ink could spill on your clothing and make
stains that cannot be removed.
Never break the seal on the printhead package until
immediately before you install the printhead. Always
handle the printhead carefully after breaking the seal.
If the printhead is stored after the seal has been
broken, the nozzles may dry out and lead to poor print
quality.
If you need to store a printhead temporarily, place it
with the nozzles (a) and electrical contacts (b) facing
down. Damage to the nozzles or electrical contacts
can lead to poor print quality.
Never attempt to disassemble or alter a printhead.
Doing so may damage the printer.
Never touch the nozzles or the electrical contacts on
the printhead. Doing so may cause printing problems.
