Do not replace the main controller PCB and the maintenance cartridge relay PCB (ROM board) at the same time.
Both PCBs hold vital information, such as settings and a carriage drive time. Before either PCB is replaced, such information is temporarily saved through internal
communication with the other PCB and is automatically written to the new PCB when it is installed. For this reason, the two PCBs cannot be replaced at the same
time. To replace both PCBs, work in order of (a) > (b).
When the main controller PCB and maintenance cartridge relay PCB have been replaced with service parts, check that the latest version of firmware is installed in
them.
If not, upgrade the firmware to the latest version.
