I am running an HP DesignJet z6200 and need to replace the maintenance cartridge. I ordered an HP 771 cartridge, but the maintenance cartridge currently in the machine is an HP 91.
Did I order the wrong part? From what I can tell it looks exactly the same.
Is there a difference between the HP 91 and HP 771 maintenance cartridges?

All of the documentation I can find suggests that the Z6200 should use the 711 cartridge.
The 91 cartridge is listed as a supply for the m6100.
It is always possible that there is no difference.
