HP Recommended
Product: Designjet 6100PS 42"
Operating System: Microsoft Windows 7 (64-bit)

I have a z6100PS that won't recognize the maintanence cartridge.  All the diagnostics from the front panel check out.  

 

Can anyone tell me how the printer recognizes the cartridge?  Tried reinstalling the old one and it won't recognize that one either.

 

I've checked the line sensor; took it out and cleaned it.  It loads paper just fine.

 

Where else should I look?

I don't work for HP....I just repair their printers.
