Procedure to flash from internal ROM’s
General:
There exist a critical point of time on which you may not switch of the machine
while you reflash it. Normally if you wait long enough there will not occur any
problems. In case something rare happens during reflashing and you are unable to
boot the pcb then there exist a method to falsh the flash Rom’s from internal
Rom’s.
Procedure:
1. Do all the necessary stuff to expose the main PCB, make sure the unit is not powered on.
2. Put in MW9955 and MW9965 in (LO and HI are marked on the PCB)
3. Put jumpers next to the ROM’s on 12 and 34 (this usually means that they all have to be put
one pin lower).
4.Power the unit on, wait for at least 5 minutes (the cutter beeps if it is ready).
5.Power the unit down.
6. Remove the ROM’s, put the jumpers back on position 23 and 45.
7. Power the unit back on and check whether the flashed PCB works.
8. Put everything back you’ve disassembled.
