I have a LaserWriter Plus that shrinks any image that I print. After I
replaced the scanner, the problem went away for a while. Now the shrinking
problem is back again. I'm curious as to whether the problem was caused by
just the scanner or something else.
It may be that either the motor, the DC Power Supply/motor driver PCB, or
the DC Controller is causing this problem. On more than one occasion the
power supply has been the culprit.
