Hello All. I'm a bit confused about the power requirements for a stepper motor out of an Epson printer. According to the service manual it's driven by 42V and the resistance of each coil is 5 ohms. That seems like way too much power for a printer carriage drive. The stepper is a EM-233 (STP-42D135-01); I've been unable to locate a data sheet for it. The stepper is driven by a SLA7043. The service manual describes that IC as supplying a 'constant current source' controlled by 3 bits of data. Does that have anything to do with keeping 8 amps of power from flowing through the coils of that stepper? I have a feeling I'm missing something here as far of the power to that stepper. Would appreciate any input. - Scotty
