5.2 Printhead Replacement
þ Note: The printhead is fragile; use extreme care when handling and never
use a sharp object on the surface. If you have any questions or
concerns regarding this procedure, contact a qualified technician or
Technical Support before proceeding.
If the printhead must be replaced, Locating Pins eliminate the need for printhead
alignment after the installation. To replace the printhead:
Œ Touch a bare metal part of the printer’s
frame to discharge any static electricity
that may be present.
• Turn ‘Off’ and unplug the printer. Open
the access cover, if ribbon is installed,
remove it.
Ž With the printhead locked in the down position, loosen the Printhead
Mounting Screw (it will remain captivated in the assembly).
• Rotate the printhead latch forward. While holding the Printhead, raise the
assembly. Disconnect the two Cables and then remove the old Printhead.
• While carefully
holding the new
Printhead, connect
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 5.3.1.
“ Reload ribbon (if removed), lower the printhead assembly, and rotate the
printhead latch back, into the locked position. Plug in and turn ‘On’ the
printer. Print a Validation Label from the Quick Test menu; see Section
4.3.5. If necessary, adjust the print darkness to match that of the previous
printhead using the Print Control/Custom Adjustments/Darkness setting in
the menu; see Section 4.1.3.
