7900 Chip resetter number of pins?


I just received a 7900 cartridge chip resetter from IJM. (On the box: ACC-RESET-7900-USB JAN 2018.) It’s the USB type and has the correct body to fit a x890/x900 cartridge but it only has seven pins, not the nine pins that would fit the chip. The pins are spaced the same as for the X800/X880 cartridges. Please advise… thanks!

It only uses 7 pins. Align it to the chip as seen on this video.


OK thanks! Will do that.
