19,0XX.4x Printhead Calibration Faults

The root problem for this error is temperature sensitivity with the power supply's opto-isolator
chips. The following troubleshooting procedure applies to this error:
Printhead Calibration Faults
19,001.46 The HFD server failed due to NVRAM operation. THis fault should only occur
when the system is in manufacturing mode.
19,002.47 The system attempted a Printhead operation without position data in NVRAM.
19,003.48 Scale and offset voltage error too large. Something is wrong with the Electron-
ics Module or Wave Amplifier.
19,004.40 The Printhead and Electronics Module do not match.
19,005.41 Improper ground connection
Initial Actions
• Check electrical connections to the Printhead.
• Check for obstructions or damage near the Printhead. If obstructions are cleared, retest.
• If the problem persists, follow the procedure below.
