8. PRINT UNIT, cont'd.

Printhead, cont'd.
❑ If you want to change the lateral position of the printhead, move
the #T20 Torx guide screw to its alternative position as illus-
trated to the left.
The 8 dots/mm (203.2 dpi) printhead can be fitted in either left-
hand or right-hand position, whereas the 11.81 dots/mm (300
dpi) printhead only should be fitted in right-hand position (see
later in this chapter).
❑ Connect the two cables to the printhead.
❑ Fit the replacement printhead assembly back into the bracket,
making sure that the guide screw fits into its slot and that the rear
part of the adapter is held by the two lugs on the bracket. You can
switch between printheads with different densities at will.
❑ Turn the locking handle clockwise to locked position.
❑ Put back the transfer ribbon, if any. Check that the printhead
cables do not interfere with the ribbon.
❑ 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 (see chapter 17.8).
❑ Close the front hatch and right-hand door and the printer is ready
for operation.
Printhead fitted in left-hand position. Compare the position of the guide screw
