Calibrating the Ribbon ID Sensor Board
Step Procedure
14 Read the voltage at R35; it should read + 0.75 V dc. Note: If the voltage is lower
than + 0.75, the magnet of the ID sensor is too close to the hall - effect sensor.
15 Use the blade tip of the exacto knife to slide the magnetic cylinder held by the
plastic housing at the Ribbon ID Sensor Board. This process requires moderate-
to high-level coordination and dexterity. Patience and concentration are key.
16 Place the tip of the exacto blade at the forward side (towards the ribbon hub) of
the magnetic cylinder; slide it towards the front of the printer. The amount of
movement needed is very small, half the thickness of the exacto blade.
17 Remove the knife from the Ribbon ID Sensor Board.
18 Measure the voltage at R35. If the voltage is higher than + 0.75, the magnetic
cylinder is too far from the hall - effect sensor. The magnetic cylinder should be
moved towards the ribbon hub.
