Carrier Drive, Home Position Sensor, Ribbon Feed Service Check 23XX-001 only: If the carrier stops but the print wires continue to fire (printing one vertical column of dots), or if the carrier does not move after turning the printer off and then on, inspect the area of the main logic board that is below the paperfeed motor. If this area is damaged or cracked, replace the main logic board. Also check the continuity of soldered-on fuse FU1 located on the main logic board near the paper empty sensor. If this fuse is open, replace the main logic board. Turn the printer off and then on. The carrier should move to the left, contact the home position sensor on the left side frame, and immediately move slightly away from the sensor. A Home Position Error occurs when: • The sensor is not closed. • The sensor is not quickly opened. • The sensor is closed any time other than when the printer is turned off and then on.
