with no tape, the Data Products servo ran open loop.  You'd think what 
you said was true, but IIRC, you didn't run them with no tape.

Later the 2230/60/90s had solid state and it wasn't a problem any more.  
I don't know about this printer, but in the 80's a lot of the printers 
worked similarly to the Data Products.
