Re: NVM RESET for 093-937
CRUM data mismatch on the Y toner cartridge. Probably on all of them the Y will post first. Is it a new toner cart? -
Re: NVM RESET for 093-937
my good friend Interface, thanks for responding. It's only showing for the Y. i posted on the board about this problem and was walking through some steps with adriansto , and he has been really helpful, but we still haven't gotten it resolved as yet. as was wondering if maybe it's just as simpole as clearing the nvm
(xerox 7775. giving me an error on yellow cartridge, tried to put 3 different new ones in and still getting the error. the machine says 093-937 Toner cartridge crum y authentication data is different in the error logs. I took a part the front where the toner cartridge crumbs are, i swapped the k1&c Crumb PWB with the M&Y crumb PWB to see if it was that, and I still got the error for the Yellow. so I then checked the p/j414(a9-a11) with pj172(2-4) for continuity and they were in the right range. the manual is saying ned change the MCU PWB, but that is very expensive. is there any other suggestions you guys can offer? or is there a chip on the board itself i can look at which could be causing this?
did the NVM INIT. after reboot still comes with "YELLOW TONER Y IS NOT COMPATIBLE" even when the toner is not in, it is saying the same thing. i swapped the CRUM PWB with (K1 and C) as this is the (m and Y) CRUM PWB and it made no difference, i would figure if it was the CRUM when i swapped, then it should show that the cyan is now having problems. I changed to Toner dispenser also to see if maybe the one that's in isn't allowing signal to be processed properly but same thing.
with pj414 on mcu pwb disconnected its saying the same thing. and of course it would say close the front upper door also since it's disconnected.
that's why i want to see if i can do a code reset before i go to the next step of replacing board. thanksComment
