Printhead/Wax System Purge/Prime
Normally, the system should be fairly easy to prime. Prior to
shipment, the system will have been print tested, then allowed to
cool thoroughly before it is prepared for shipment. When the wax
solidifies, there is little chance that air bubbles will develop. The
wax reservoir will typically contain 150 – 250 ml of wax, which will
be enough to prime the Printhead at installation. It is very
important that the following Safety Precautions be followed when
working around the WaxJet Printhead/Wax System.
Safety Precautions
•
Ensure that existing Printhead/Wax System is thoroughly cool
before attempting any service on it. The Printhead assembly
reaches temperatures as high as 135º C (275º F) during
operation. Typically, a one (1) hour cool down period is
necessary after shut down.
•
Safety glasses and protective gloves are highly recommended
when performing Purge and/or Prime Procedure.
•
The Printhead and Wax System must be at operating
temperature prior to performing the Purge or Prime
Procedure. Cold spots in the wax system will restrict normal
flow and cause the wax to flow back out the vent, possibly
causing severe burn.
•
Touching the Printhead or the wax system when at operating
temperatures can cause injury. The Printhead is heated to
temperatures as high as 135º C (275º F) and will cause severe
burn if touched by bare skin.
•
Do not stand in front of or place hands in front of Printhead
while priming. The hot wax can spray up to 12” or more during
the priming procedure.
