Actually you have done the hardest part,, installing the heater... I done about 12 conversions. All you need to do is first flush your print heads with aqueous flushing liquid and after that flush it with eco-solvent flushing liquid this process will clean your lines as well, at this point you can remove the heads from the printer MAKE SURE AT THIS POINT YOUR PRINTER POWER IS OFF AND UNPLUGGED THE POWER CORD AS WELL. Next remove the printer top cover which held by small screws front and back push the carriage away from the work area. Next Remove the pump and capping station, follow up by drilling some holes to reroute the pump waste lines to closer to the front near the pump, don’t use the thin
Line extenders currently on the ink pump lines.. drill a 5/8" hole through pump assembly plate which the pump and capping station sits on,, this hole should be about 1-1/2" in away from the right edge of the assembly and 1-1/4" back from the front edge of the assembly plate. Next drill one 5/8" hole through the top of the printer main frame assembly alined with the hole you drilled above, next drill one more 5/8" hole at the bottom of the frame assembly about 1" to the right of the hole above it,,, unfortunately these holes wont lineup with each other due to there is a leg mounting plate in the way, so it have to be offset a bit from the hole above, this is the hole for the waste ink lines to exit into the relocated ink waste bottle. bottle and the cap from the rear use the mounting cap as a pattern to drill the last holes, hold the bottle cap against the frame and mark with a magic marker where the middle of the drain hole should be and also mark where the two small mounting crew holes should be.. Finally install the new capping station, solvent compatible ink pump, reinstall heads, install solvent compatible dampers install new ink.
May have to put the printer through a few cleaning cycle in order to start getting ink to the heads. By the way,,, if you flush the lines you wont have to use new ones... Good luck
