5.2Printhead Replacement
;Note: Printheads are fragile; use extreme care when handling and never use a sharp object on the surface. If you have questions, contact a qualified technician or Datamax Technical Support before proceeding.
To replace the printhead:
nTouch a bare metal part of the printer’s frame to discharge any static electricity that may be present on your body.
o Turn ‘Off’ and unplug the printer. Open the access cover; if ribbon is installed, remove it.
p With the printhead locked in the down position, loosen the Printhead Mounting Screw (it will remain in the assembly).
qRotate the printhead latch forward. While holding the Printhead, raise the assembly. Disconnect the two Cables and then remove the old Printhead.
r While carefully holding the new Printhead, connect both Cables.
s Position the Printhead onto the Locating Pins in the Printhead Assembly and secure in place with the Printhead Mounting Screw (do not over- tighten). Please note that a printhead alignment is normally not required.
tClean the Printhead; see Section 5.3.1.
uReload 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 (Section 4.3.5) and if necessary, adjust the Print Control/Custom Adjustments/Darkness setting (Section 4.1.3) so that the print contrast produced by the new printhead matches the previous one.
