Chapter 8 Print Unit
Description, cont'd.
The printhead is fitted to a bracket by means of two screws. The
printhead and the bracket are always delivered as a complete
assembly. Two hooked fingers at the rear of the bracket are fitted
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
pressing roller shaft when the printhead is closed, making sure that
the printhead becomes properly aligned with the pressing roller.
There are no facilities for adjusting the position of the printhead
relative the pressing 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 flat cable) is used for data to the
printhead and is connected to P41 (marked “TPH”) on the CPU
board.
