Bsd-on:CH15.19
When the End Guide is moving away from the home position, the End Guide Home Sensor 1 does not turn OFF within the specified time after the End Guide Motor 1 On.
Procedure
Enter the Diag Mode, input DC330[013-121] (End Guide Home Sensor 1) and turn it ON. Turn the sensor ON and OFF with a sheet of paper.
Does the display switch between ’H’ and ’L’?

Does the End Guide Home Motor 1 operate?
Yes No
Is the CR1 on the Folder PWB ON?
Yes No
Refer to BSD CH15.2 and check the +5VDC circuit to the Folder PWB J8140-4.
Is the voltage between the Folder PWB J8137-2 (+) and the GND (-) +24VDC?
Yes No
Refer to BSD CH15.5 and check the +24VDC INTLK circuit to the Folder PWB J8137-2.
Turn OFF the power, disconnect connector J8138 from the Folder PWB.
Measure the wire wound resistance of the Motor.
Between J8138 pin-7 and each of pin-8/10
Between J8138 pin-9 and each of pin-12/14
Are the resistances approx. 4.6 Ohm for each?
Yes No
Check the following connections for open circuits and poor contacts. If no problems are found, replace the End Guide Motor 1 (PL 25.69)
Between J8138-7 and J8142-2
Between J8138-8 and J8142-3

Between J8138-12 and J8142-4
Between J8138-14 and J8142-6
Between Finisher PWB J8010-6 and Folder PWB J8139-14
Between Finisher PWB J8010-7 and Folder PWB J8139-13
Between Finisher PWB J8010-8 and Folder PWB J8139-12
Between Finisher PWB J8010-9 and Folder PWB J8139-11
Check the following connections for open circuits and poor contacts. If no problems are found, replace the Folder PWB (PL 25.68), followed by the Finisher PWB (PL 25.3).
Between Finisher PWB J8010-6 and Folder PWB J8139-14
