3.2.6 BJ cartridge detection
The sensor signal from the index on the drive circuit is used to detect whether a BJ
cartridge is installed and, if so, what type it is.
The index is either open or pulled down via the resistor on the heater board.
*: Pins shared with electrodes.
The detection signals are pulled up to VCC on the logic board and are read by the IO
board of the MPU as Low when pulled down and High when open to detect the BJ
cartridge.
With combinations of index sensor signals other than above, all print operations are
disabled. When print operations are disabled, a BJ cartridge error is displayed.
*1: ID1 of the ink optimizer head is not detected by the printer.
*2: The operator uses the printer driver to select whether printing is continued using
only the color ink system, or whether printing is interrupted.
