PRINTHEAD REPLACEMENT
The quick-mount thermal printhead is easy to replace:
• Turn off the printer.
• Open the front and right-hand doors.
• Lift the printhead and remove the paper and ribbon stocks.
• Turn the printhead lock handle counter-clockwise to open posi-
tion, see illustration.
• Remove the printhead assy carefully as far as the cables allow.
• Remove the two printhead cables by pulling at the connectors.
• If you want to change the lateral position of the printhead, move
the #T20 Torx screw to its alternative position (8 dots/mm
printheads only).
• Connect the two cables to the printhead.
• Fit the replacement printhead assy back into the bracket so the
guide screw fits into its slot and the rear end of the assy is held by
the two lugs. You can switch between 8 dots/mm (203.2 dpi) and
11.81 dots/mm (300 dpi) printheads at will.
• Turn the locking handle clockwise to locked position.
• Load paper and transfer ribbon. Then lower the printhead.
• Turn on the power. At power-up, the printer will automatically
reset itself to the characteristics of the printhead in regard of head
resistance and density.
• Close the front and right-hand door and the printer is ready for
operation.
