The printhead is fi tted to a bracket using two screws. The printhead and
the bracket are always delivered as a complete assembly. In case of Easy-
Coder PF4i and PF4i Compact Industrial, the printhead ribbon break
shaft (see Chapter 6.8) is also included. 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. A U-shaped tab on the outer side of the bracket engages the guide
link 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 longitudi-
nally nor laterally.
EasyCoder PF4i has two holes in the outer fi nger for fi tting an optional
spring that secures the printhead when the printer is tilted forward (not
used in EasyCoder PF4i Compact Industrial).
There are two cables from the printhead to the CPU board:
• The innermost cable is used for the power to the printhead and is con-
nected to P5 at the front of the Power Supply Unit.
• The outermost cable is used for data to the printhead and is connected
to J40 on the CPU board.
