(EasyCoder 501 XP and 601 XP), cont.
The printhead is fi tted to a bracket using 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 facil-
ities 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.
