Switch-on and Reset Behaviour of the Printer
Switch-on Behaviour of the Machine
− Main switch (1) on the Paper Processor ON
− Mains voltage present on the Main-PC
− Main-PC in Sleep mode (Timer plug-in unit in
operation)
− Printer and Scanner unit dead
dlabr125
The Timer switches on the Main-PC in
accordance with the preset switch-on time
1 Main switch
2 RCD device
The operating and user systems are booted
The mains voltage for the Paper Processor and
the power supply unit of the Printer / Scanner (via
interface RS232) is switched on
All secondary voltages (except the 24V/36V
motor, laser, lamp voltage) are switched on
The booting on the Printer Mainboard is started;
all registers are initialised
The FPGA is loaded (freely programmable logic
circuit)
Command interface to the Main-PC available
Initialisation of the SPI interface (prerequisite:
Reset by the Printer-µC on P4.4 inactive)
The power voltages are switched on by a
command of the Main-PC via the Printer
Mainboard
Check of the status of the motor voltages by the
AVR Controller on the SPI interfaces
