Printer Testing

1. From the service screen press (F4). The printer should print out a short test print that should be legible.

Solenoid Valve Testing

1. From the service screen, activate the drain pump, open the reservoir lid, and ensure fluid is not returning to
the reservoir through the HLD return solenoid. Slightly raise the drain hoses from the drain standpipe and
verify no fluid is flowing through the drain hoses from the drain and residual solenoids. Deactivate the drain
pump.
2. Activate the HLD feed pump and verify no fluid is leaking into the processing chamber through the HLD feed
solenoid. Deactivate the HLD feed pump.
