5.2 Printhead Replacement

þNote: 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.

ŽWith 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.
