5.4 Printhead Replacement
Notes:
The printhead is fragile; use extreme care when handling and never
use a sharp object on the printhead surface.
If you have any questions or concerns regarding this procedure,
contact a qualified technician.
Locating pins eliminate the need for an alignment following the installation of a
new printhead. To replace the printhead:
Touch a metal part of the printer’s frame to discharge any static electricity
that may be present on your body.
Turn ‘Off’ and unplug the printer. Open the Access Cover, rotate the
Printhead Latch forward and raise the printhead. Remove the ribbon, if
installed.
Lower and rotate the
Printhead Latch to the locked
position.
Loosen the Printhead
Mounting Thumbscrew (it
will remain captive in the
assembly). Rotate the
Printhead Latch forward to
the unlocked position.
Raise the assembly and while carefully holding the Printhead, disconnect
the two Cables and then remove the Printhead.
While carefully holding the
new Printhead, reconnect
both Cables.
Position the Printhead onto
the Locating Pins in the
Printhead Assembly and
secure in place with the
Printhead Mounting Screw.
(Do not over-tighten this
screw.)
Clean the Printhead; see
Section 5.6.1.
Reload ribbon, if removed. Lower and rotate the Printhead Latch to the
locked position. Plug in and turn ‘On’ the printer.
