Sadly, replacement may be the only alternative. What is particularly
annoying about this defect is that the whole mechanism is only there
because Epson doesn't want the owner to have the option of using 3rd
party inks. You'd be amazed how many problems regarding the ink
monitoring/chip monitoring system I hear about. While you end up paying
in some manner for the R&D and costs involved in integrating these
"features" into the machine, it is Epson who directly benefits.

When complexities are added to something fully for the benefit of the
manufacturer, it should be their responsibility to repair them for life,
IMHO.

Of course you've tried removing and connecting again all the cables?
Sometimes a bit of dust/whatever can go near the contact are of flat
cables (I'm assuming those are flexible-PCBs) and do sth wrong with
contacts. F.e. interfere with Vcc/GND and as soon as you install 4th
cardridge - there's not enough power (the device can work without either
VCC or GND because of cmos protection diodes - but only under extremely
light load, like only 2 or 3 chips in your case).

Art - I agree with you on the manufacturer being responsible but don't
ever look for that to happen. What I hated most about the chip is it
forced you to replace the cartridge when there was still about 1/3 the
ink left. So not only do you pay exorbitant price for the ink, you
don't even get to use it all. Oh well, if it gets too bad I'll just
revert to the old LaserJet and settle for printing everything in black
and white.

Guess I'll just have to get a replacement and create more landfill
fodder with the old one. Tired of messing with it and getting
nowhere.

Jerry - yeah, been through all that. Removed the cables, cleaned the
contacts and cable ends, removed the IC board in printhead and cleaned
contact points - been through every cable, wire, and connection.
Nothing solved problem.

Thanks for trying to help guys.
