3.2 Control Unit
The control unit consists of the following (see Figure 3.2):
. Control circuit
. operator panel
. Hammer magnet driver (with the register unit only for
. Power supply
Control circuit
The control circuit is on one PC board and is installed in the maintenance
section,
which can be accessed by opening the forms rack at the rear of
the printer.
The control circuit uses 2 microprocessors;
one for interface control and
the other for printer control.
The LSI for print control reduces the number of parts and improves
reliability.
Operator panel
The operator panel is located at the upper front of the printer.
Control
switches and indicator lamps on the operator panel
on a PC board.
Hammer magnet driver
The hammer magnet driver for the 136 magnets is on one PC board. In
M3041, M3042, it is installed on the rear of the print unit and is
connected directly to the magnet assembly on the PC board.
In M3043, the
hammer magnet driver is installed near the control circuit board and the
lead from the magnet assembly is connected to the hammer magnet driver
through the register unit.
A simple circuit is achieved by using custom
and a transistor array,
enabling easy detection of faulty columns.
Power supply
The power supply consists of the supply unit and a transformer.
The transformer is connected to an AC input through a line filter and a
circuit breaker.
Input voltages of 100 to 240 V can be selected by
switching the appropriate tap on the transformer.
The power supply unit has regulation circuits for logic circuits and
hammer magnet driving, a forms feed stepper motor drive circuit, and
control relays
for the AC motor.
