ante Posted October 10, 2004 Report Share Posted October 10, 2004 Stuee,What kind of power requirement does the projector have? And what kind of power supply input does it have (transformer of switch mode)? Do you need a timer for cooling the print head? Why no just put a micro switch (a small one like in VCR: s) at the park position and let a small fan blow while in park position? Quote Link to comment Share on other sites More sharing options...
stuee Posted October 11, 2004 Author Report Share Posted October 11, 2004 Unsure about the projector, i just know its 240v au. its my friends.As for the timer, the printheads are xaar heads and need to either be sprayed with solvent every 10 mins or so or purged to push ink through them to stop them drying out, the heads are like $600 each and each printer has 24 in them.
