Epson XP-15000 Still Reporting Ink Empty

[Epson XP-15000 Still Reporting Ink Empty]

I'm not printing blank pages. I've been printing fine.  But after printing about 5-7 pages, it reports the white inks (grey and red on the Epson 150000) need to be replaced.

I thought the chipless firmware made the printer report the inks full at all times.

Successfully flashed the firmware (or so I thought), but the printer keeps reporting the white ink as being empty after about 5-7 pages printed.  I'm using a CISS system, and I have to "replace" the white ink carts in printer's menus.  

I thought that the custom firmware was supposed to take care of the ink monitoring?  Did it not flash correctly?  How can I check to see if I'm running the correct chipless firmware?

Thanks in advance,
Chuck
