My HP Deskjet printer 5740 doesn't recognize my new HP Photocartridge 348

[Thinkie]

My HP Deskjet printer 5740 doesn't recognize my new HP Photocartridge 348. It's brand new, not expired, official but I only get black prints. I can not find anything helpfull on the HP support site. The printer is not set to only print in black.

The cartridge goes into the slot for black cartridges, there is no colourcartridge in the other slot at the moment. So either it needs a colour cartridge to work together (but how will I know I'm not just printing my photo's with the colourcartridge and using the photocartridge as an expensive black cartridge?) or the printer thinks the photocartridge is just another black cartridge.

Any suggestions?

The Photo cartridge does not have all the colors, it has Photo black, light cyan and light magenta.  It is used in conjunction with the color cartridge (which supplies cyan, magenta and yellow) for photo printing.

If you want to print in color you will need a color cartridge.  The color cartridge can print black (approximately) by itself but the photo or black cartridge cannot print color without the color cartridge.
