New subject: weird problem with our Decwriter III terminal

22 Jun 2006

I would start with the gears first. Stepper motor
testing can be done by visual inpection by running
through 1 character at a time. Mark each turn when
moving to the next character. This requires diassembly
of the casing and other visual blocking components.

 Hi,

 maybe someone here can help us - our problem is that
 the
 decwriter terminal seem to "jump" in particular
 positions
 when printing

 we don't understand how to solve this problem -
 maybe this is a
 stepper motor problem, or another problem in
 gears/transmission?

 the problem is evident in this image:

 does someone have an idea about this problem?
 tnx!

 :)
