Digital BW, The Print

Austin,

Sorry for the delay in replying - been away. My 1270 and 1290 definitely do
not have stepper motors, but use encoders as you suggest. The service manual
for the 1270 states that the encoder sensors have a minimum resolution
(carriage and paper motor encoders) of 1/180". Haven't got a manual for the
1290 yet.
