Guess that'll be v2 after v1 fails. I'm going to try to bounce the ir off the table. I mitigated the ambient light problem by pulsing the IR led at 12khz and wiring a basic pulse detector circuit. That gets piped to an opamp to boost signal and act as a schmitt trigger. Is working on the bench. Got to move it onto protoboard and figure out a way to mount it before it can break my heart.

You should just need a new cartridge unless you melted the thermistor. They should be the same but I've never checked. When you turn on the printer is the temperature reading correct?
