8.2.5 VERTICAL MAGNETIC DEVICE OPTION - CHECKING FOR CLEARANCE BETWEEN
THE HEAD AND PRESSURE ROLLER
MACHINE CONDITION:
Machine powered off, without the case installed and with the vertical magnetic device option in its
parking position.
OBJECTIVE ADJUSTMENT:
Check for clearance between the magnetic head and pressure roller.
PROCEDURE:
Power on the printer and wait for its initialization to complete.
Through the rear opening, visually check for the minimum clearance required by using a 0.2 mm probe
(making sure that the head remains stable). The maximum clearance must not exceed 0.4 mm.
If the tolerances are not respected: power off the machine; insert a mylar thickness (1) in the area of
the magnetic head where the paper does not pass as shown in the figure.
Power on the machine and after its initialization check the clearance again.
