Description: Lower lift motor problem • When the lower cassette is inserted, the lower lift limit switch does not turn on within 6 s of the lower lift motor turning on and the lower lift limit switch does not turn on by turning off the lower lift motor for 200 ms and retrying twice. • During printing, the lower lift limit switch does not turn on within 200 ms of the lower lift motor turning on.
Causes: Broken gears or couplings of the lower lift motor. Defective lower lift motor. Poor contact of the lower lift motor connector terminals. Defective lower lift limit switch. Poor contact of the lower lift limit switch connector terminals.
Remedy: Replace the lower lift motor. Check for continuity across the coil. If none, replace the lower lift motor. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check if YC13-B15 on the engine controller PWB goes low when the lower lift limit switch is turned off. If not, replace the lower lift limit switch. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
