Dear @sglickster, these chips are not meant to “reset” per-say, as they are actually meant to control the OEM chip to show full at all times. Can you confirm that you have not tried to reset them with the maintenance tank resetter we sell for this printer?
Regarding chip fit, YES, this is the weak link with this printer. The small metal solder points at the back of the control chip can lead to the chip not making proper contact with the internal sensors in the printer.
One thing I suggest to do before anything else: tape down the control chip to the cartridge over the solder points at the back of the chip. This will do two things, it will align the chip better and it will make better contact between the poles and OEM chip.
Every Epson printer has different ink bay dimensions. I’ve had some 38xx printers that are a total beast to fit chips into and others that are perfect (with the same carts).
