19,001.4X
HC_DEV_FAULT (0x01)
Occurs during the scales and offset calibration. If this
process fails a fault is declared. Any part in the chain
could be responsible for the incorrect reading including
the print head electronics, the A/D electronics, the
waveform generation electronics, power supply, Wave
Amplifier (on the power control board), print head
interconnect cable, etc.
19,002.4X
HC_DEV_FAULT (0x02)
Occur when the printer is attempting to determine how
many data taps the print head uses. If this process fails
an fault is declared. Any part in the chain could be
responsible for the incorrect reading including the print
head electronics, the A/D electronics, the waveform
generation electronics, power supply, Wave Amplifier (on
the power control board), print head interconnect cable,
etc.
