Digital BW, The Print

I have an Epson R280.  I purchased an Eboni cartridge to replace the 
Epson black cartridge.  I have followed the procedure in the Epson 
manual for replacing cartridges and with the Eboni cartridge installed
and now both the green power light and and red ink light are lit 
indicating expended/uninstalled/incompatible cartridges.  The Epson 
status utility shows the black cartridge as expended and all other 
cartridges as uninstalled.

Have I missed a step somewhere?  The exact cartridge I purchased was:

RCN-T0771-K  	B&W Ultratone UT-RCN Matte Black Eboni CARTRIDGE for EPSON 
STYLUS PHOTO R260/R380/RX580 - BLACK Position w/Auto Reset Chip

Thanks
