7.1 Overview
This chapter describes all the electromechanical parts of the printer with their main electrical
and mechanical requirements to allow the field service technicians to check the correct
functioning.
7.1.1 Print Head
The print head installed on this printer is an electromagnetic non-ballistic type.
The needles of the 24-pin printhead have diameter of 0.2 mm (0.0087") and they are
positioned in a diamond layout in which the odd pins (1÷23) are positioned in the right row
with the vertical pitch of each row of 0.282 mm (1/90").
Needle 1 is the top most of right row, needle 2 is the top most of the left row.
ELECTRICAL REQUIREMENTS
