Quick Start Guide
Your printer is equipped with shutoff valves for the ink delivery lines on the
carriage. When the valve is pushed to the upright position, the ink delivery lines
are closed at the carriage. This maintains negative pressure while installing and
priming the ink delivery lines.
Note: When filling more than one color of ink, be sure to thoroughly wipe any
excess ink from the ink primer before working with the next color to avoid the
possibility of contamination.
To install needle assemblies and prime delivery lines
1 Close the ink delivery lines by pushing the valve up.
