Previously my ink supplier's Riso compatible GR 3770 HD black ink has worked fine.
But today's newly received black ink shipment isn't working although the tubes appear to seat properly in the machine: when a tube is inserted in the drum, it didn't remove the Message, "Install Ink Cartridge." The new shipment doesn't say "HD" but it does say, "Digital Duplicator Ink Premium Black: GR/RA/RC series." In addition there is a sticker added that says, "For use in Risograph 3750/3770, RC/RA, 680GRF"
I phoned the supplier and questioned whether the problem is that it isn't HD ink, but they say this is what they ship to 3750 and 3770 machines and it works fine.
Note: I tried using my exhausted cartridge (which does say "HD") again after pushing the disk inside further to the front with a stick, and the machine accepted it like a new cartridge and said "close front cover" so I take that to mean the machine works ok when the ink and cartridge are right.
Question: If I have been supplied non HD ink, should it work anyway in my GR 3770 Riso?
I'm going to talk again Monday with my supplier who is very willing to make things right. Any suggestions about this problem? Thanks, Charles.

Thank you. Upon examination I see that the tabs are different. That is valuable information and it helps. (I wondered how the machine could be so smart).
