the paper path. Make sure the flags of the duplex unit input and exit
sensors move freely.

While the 23 is displayed, press and hold the Return button while press-
ing the second button from the top, and note the 7th and 8th digits from
the left. If they are 01 or 03, there is a problem with the duplex input
sensor signal. Remove the duplex top cover and table cover and rein-
stall the duplexer on the printer. Measure the voltage on J5-12 of the
duplex system board; it should fluctuate from 0 to +5VDC as you toggle
the sensor. Check the sensor cable continuity. If the sensor and the
cable are good, replace the duplex system board.

If the 7th and 8th digits are 04, there is an exit sensor problem. Remove
the duplex top cover and table cover and reinstall the duplexer on the
printer. Remove the paper tray so you can reach the sensor. Measure
the voltage on J5-8 of the duplex board; it should fluctuate from 0 to
+5VDC as you toggle the sensor. Check the sensor cable continuity. If
the sensor and the cable are good, replace the duplex system board.

Fan (927 Error)

The fan should run continuously when the printer is powered up, unless
the printer is in Power Saver mode. Check that the fan rotates freely
when spun manually and that the cable connections to the fan are OK.
The voltage at engine board J2-7 should be approxi24VDC
when the top cover is up. Short J2-7 to ground (J2-6) to test the fan; if
the fan does not run check the continuity of the fan cable before replac-
ing the fan. A bad fan can pull down the +24V line even if it runs; check
that J2-8 has b21 and +26VDC when the fan is running; if it
does not, replace the engine board.
