Similar to HP 46 ??

I've got my "NEW" HP 46 opened up on the bench and the printer module physically removed but still electrically connected. I have checked the 15 V supply and it seems OK as well as a couple other test points on the board which have voltages marked. The wheel inside the printer module spins and if I manually close the little relay contacts, the hammers function but no data prints when I push the print key. All that happens is the display goes dark and the "COGITATION" light comes on.

I can't do much more without a service manual or at least some diagrams. I see there is an operators manual available for $10 which I will order. Does anybody know where I can get a service manual?

The machine is absolutely beautiful inside. It even smells new. The print ribbon looks barely used, I'd be willing to bet it is the original ribbon. The light colored keys are slightly discolored from age and there was a little bit of dust beneath the keys. There were two Service Cards tucked into the little pocket next to the printer instructing the owner on how to ship the calculator to Hewlett Packard in Loveland, Colorado. The machine came in it's original carrying case with two extra rolls of adding machine paper, a dust cover and a power cord.

I am totally thrilled with this machine.
