This is really the key to open the Markem Imaje continuous inkjet printer, which is not a rarely seen spare part for technicians. However, without this key, we are not able to open the printer body chamber nor check the inside.

So without further duo, when we go out and maintain the MI printers, remember to bring 1 piece of this key with you. The key is not exclusive to a certain MI printer, so you could apply it on all the MI you are looking after.
It’s an important key for Markem Imaje printers, but thank goodness one is enough.
