The cartridge is a new original. My question is relating to the compartment in the printer. I have tried cleaning contacts. The color compartment (No. 78) has a spring loaded bar between the copper pins. This is compressed when the ink cartridge is inserted.There is no such bar on the black ink side. Should there be? If anyone has a deskjet printer can you confirm if there is a spring loaded bar on the black ink side. I tried ringing hp but gave up. Thanks.
