Refills don't seem to work

[LeighWillaston]

I have a HP Deskjet F 4185, and in the past it has worked well with refilled black cartridges, and I have used HP colour cartridges.

Now it won't seem to accept refilled black cartridges.Is there a reset?

thanks

Refilled HP cartridges being rejected is a common problem. See this thread for more info: http://www.nifty-stuff.com/forum/viewtopic.php?id=7882
