Deskjet Printer Encoders

So I scored a BIT of a deal today.

One of the departments was "surplussing" a large number of their
Deskjet printers. This meant they were going into storage where they
would sit collecting dust for 20 years before finally being thrown away.

This being a sin, I had to take a screwdriver to them asap, before the
delivery guys got there.

What I ended up with was a handful of the ink cartridge driver motors,
which are in fact little servos with NICE little encoders on the back.

It is my plan to use the encoders for .. something. Not clear on what
yet, but they're too good to throw out. Better they should in my
basement .. for the next 20 years .. than be thrown out today.

Here's some questions, though, that might get them back into service a
bit quicker.

1. The encoder assembly is a QEDS-9500 . ( Yes, "Q" ) I have no
information on this device, nor does HP or Agilent. Does anyone here
know what its capabilities might be ?

( Physically, it LOOKS just like an HEDS-9200, but whether it is or
not ... )

2. Is there any conceivable reason to use these as servos ? To NOT rip
the codewheels out and throw away the motors bits ?

Thanks in advance.

Alan
