Dummy color cartridge for HP color printer

[Webstop]

Does anyone know how to make a dummy color cartridge for HP 660C printer? I use only black cartridge, but the printer would not work without color cartridge installed. There should be a way to make printer think that this cartridge is installed and it is full.
Any ideas?

I bought my Refill Kit in Hongkong.
Any HP 51629A refill kit would do.

I'll send u the procedure and drawings
thru email attachment--what's ur
e-mail address?

HP 660c will continue to print even the
color cartridge is empty as long as it is
on the cradle. You can use only black
as long as the two cartridges are present
and ur black is not empty.

pls. keep me posted what's ur printer
is doing if u run-out of color aside from
black.
