Phaser 840 and 850 Color Printers
19,000 Head Calibration Fault
19,001.4X
HC_DEV_FAULT (0x01) Occurs during the scales and offset calibration. Any part in
the chain could be responsible for the incorrect reading
including the printhead electronics, the A/D electronics, the
waveform generation electronics, power supply, wave
amplifier (on the power control board), printhead
interconnect cable.
19,002.4X
HC_DEV_FAULT (0x02) Occurs when the printer is attempting to determine how
many data taps the printhead uses. Any part in the chain
may be responsible for the reading, including the printhead
electronics, the A/D electronics, the waveform generation
electronics, power supply, wave amplifier (on the power
control board), and printhead interconnect cable.
22, 000.00 Paper path fault. Caused by some unexpected event during the printing
process
22, 000.01 Paper path fault. Caused by a timeout during the printing process
22, 024.01 Printhead park . The printhead was not found parked upon power-up;
Phaser 850 printer only
