Steve,



It's interesting that you say that. Out of the 25+ Epson and HP printers
I've torn down for parts, the vast majority use stepper motors over DC
servos. The ones that did use DC motors, but not necessarily servo motors,
used them for gross movement in the Y direction after being significantly
geared down.



In general, stepper motors are far cheaper than true DC servo motors. DC
motors with separate optical encoders are a different story.



Regards,







Paul Symansky
