Chapter 8 Print Unit
8.7 Printhead, cont.
58
Description, cont.
The printhead is fi tted to a bracket by means of two screws. The
printhead and the bracket are always delivered as a complete
assembly. Two hooked fi ngers at the rear of the bracket are fi tted
over the headlift shaft so as to hold the printhead in place. Two
U-shaped tabs on either side of the bracket connect to bearings on
the platen roller shaft when the printhead is closed, making sure
that the printhead becomes properly aligned with the platen roller.
There are no facilities for adjusting the position of the printhead
relative the platen roller, neither longitudinally nor laterally.
There are two cables from the printhead to the CPU board:
• The outermost cable (protected by a black plastic tube) is used
for the power to the printhead and is connected to X2 on the
Power Supply board.
• The innermost cable (20-p blue fl at cable) is used for data to the
printhead and is connected to P41 (marked "TPH") on the CPU
board.
