I have a Epson 740 Printer that is not recognizing the black ink cartridge. It is a purely hardware issue because I have narrowed it down to the switch in the ink socket. Anybody ever have this problem. I am either looking for a schematic or a way to bypass that switch. I would prefer some guidance before I start trying to pull this thing apart.
I need this printer to work because it is hooked up to a proprietary DOS based retail sales register system, coded for the Epson 740 print format. The guy who built the system would charge use a $$$$ to re-program for a new printer.

Thanks for your help, Charles

Hi C-VENN
It may be safer to replace the print head.

I have an Epson Stylus 600 that is about to go to a recycling center (permamently clogged ink nozzles). If you could post a pic or description of what parts you need, I can send them to you if it looks like they would work in a 740 printer.
