Hello guys.

I have a problem. Where can I find more data about logic board ( QM2-1477 qk1-0763-03 ) on the Canon iP1500. Or any info about those two chips:


TBG2207BFG (it looks like some DC motor driver)


I tried all around the web but failed to find anything notable.

I'm trying to convert this printer into the plotter so I need some additional info about it, preferably some info how to flash eeprom and where to find some source code.
I'm aware some of that is proprietary but any info or advice what to do would be greatly appreciated.
