Replacing the Printhead

Replacing the Printhead
Replace the printhead if two consecutive Head Cleaning B
executions do not restore acceptable print quality, if
ERROR E02813 is displayed, 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
When the ink supply runs low in an ink tank, procure a
new ink tank for replacement as soon as possible.

Printhead Handling Precautions

Always follow these precautions when handling a
printhead.
Caution
Always store a 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.
4- 23
Never touch a printhead immediately after printing has
stopped. A printhead becomes extremely hot during
printing and can cause minor burns.
Important
Try to avoid dropping or shaking a printhead. Spilled
ink can stain the work area.
The ink supply port of a removed printhead may be
covered with ink. Always handle a printhead carefully.
The ink could spill on your clothing and make stains
that cannot be removed.
Never break the seal on a printhead package until
immediately before you install the printhead. Always
handle a printhead carefully after breaking its seal. If a
printhead is stored with its seal broken this can cause
the nozzles to dry and lead to poor print quality.
If you need to store a printhead temporarily, set it with
its nozzles (a) and electrical contact points (b) pointing
down. Damage to the nozzles or electrical contacts
can lead to poor print quality.
b
Never attempt to disassemble or alter a printhead.
This could damage the printer.
Never touch the nozzles (a) or the electrical contacts
(b) on the printhead. This could cause poor paper
feed.
