Epson 7600: "No maintenance tank". Tried several MT/chip

Customer Question

Epson 7600: "No maintenance tank". Tried several MT/chip combinations, non recognized.
Wondering if the MT sensor is worn out (#664 in service manual: "PCB assy IC") I see 6 wire contacts, should there be 7? Did one break? Easy to replace, or is there a work-around? Thanks,

Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. I want to warn you that it is possible you will need to replace a part in order to fix this. There are a few different things that can cause this and a couple different parts so we would need to troubleshoot to find out for sure. Have you tried replacing the entire maintenance tank yet? Just changing the chip on it does not always work.

I've 2 maintenance tanks, several sets of chips, no combination works.

Do both of them have replaced chips? I actually meant replacing it with a new one that does not have a generic chip.

Customer: replied 1 year ago.
One of chips read "MT full" . That same chip now reads "No MT". It looks like the chip has 7 spots of contact. Looking closely at the chip reader after pulling the cover back reveals 6 wire pin contacts. One in the middle looks to be missing/broken? I believe I need a new MT chip sensor, #664 in exploded service manual diagram - "PCB assy IC". Are there supposed to be 7 wire pin contacts, not 6? (It does not show in diagram.) If so, is there a temp work-around till I find a replacement part?

I apologize but I am going to need to opt out and open this to all experts.
