had to restring the cables to a paper deck-seemed to go well untill power up. The copier recognizes the prescence of the deck, however the is no action by the motor-was late in the day0cust closing. I was hoping someone with some similiar experience could tip me to the cause of this-motor or the dc controller, hoping to jump start this! Thanks!

I can't remember for witch model is this deck.Probably is old.Maybe NP 6016? Or I kicking in the dark.If it ain't broke, don't fix it

NP6560-6360-6260
Deck lifter
motor (M102)
DC controller PCB
Deck open detecting switch (SW102)
Set the meter to the 12VDC range. Does the voltage between 2001A-3 and GND (–) on the DC
controller PCB change from about 0 to 5 V when the deck is closed?
Deck lifter position sensor(Q110)
DC controller PCB
Set the meter to the 12VDC
range. Does the voltage between J2001A-4 (+) and GND (–) on the
DC controller PCB change as follows?
when the deck is closed, 0 V
when the deck is opened, 5 V
Opening/Closing the Deck
When the deck OPEN switch (SW100) is pressed, the deck lifter motor (M102) starts
to rotate and the lifter inside the deck starts to move down. The deck motor stops when
the deck paper supply position sensor (Q103) detects the lowering lifter. At the same
time, the deck OPEN solenoid (SL102) turns on to release the locking, and the deck will
push out to the front several centimeters by the work of a spring.
When the deck (compartment) is slid into the copier, the deck OPEN detecting switch
(SW102) is pushed, and the lifter moves up to pick-up position.
When the deck lifter motor rotates to open/close the deck, the Deck Open indicator
(LED100) on the OPEN switch PCB starts to flash.
Controlling the Deck Motor
1. Controlling the Deck Main Motor (M101)
The deck main motor is controlled by the copier’s DC controller; Figure 8-110 shows
the circuit used to drive the deck main motor, and the circuit has the following functions:
q Turning on and off the deck main motor.
w Switching the speed of rotation of the deck main motor.
a. Turning On and Off the Motor
When the deck main motor drive signal (DMON) from the copier goes ‘1’, the motor
drive circuit turns on to rotate the motor at a specific speed. When the deck main motor
drive signal (DMON) goes ‘0’, on the other hand, the motor drive circuit turns off to stop
the motor.
The copier’s DC controller monitors the speed of rotation of the motor in reference to
the deck main motor clock pulse signal (DMFG); if the pulse signal stops for a specific
period (1.4 sec during initial rotation; 2.8 sec during normal copying), the DC controller
will indicate ‘E043’ on the copier’s controller
Controlling the Deck Lifter Motor (M102)
The deck lifter motor control circuit is found on the side deck driver PCB.
The combination circuit within the figure consists of various logic circuits, and the
deck lifter motor is rotated clockwise/counterclockwise based on combinations of the
deck lifter motor drive signal (DLMON*) and the deck lifter UP signal (DLUP*) from the
copier’s DC controller PCB.
If the deck lifter position sensor does not detect the lifter within 50 sec after the deck
lifter UP signal has been generated, the copier’s service mode (*1*; ‘LIFT’) indicates an
alarm. If an alarm is noted, remove the cause, and turn off and on the copier to reset.
q Conditions for Moving Up the Lifter
• The deck (compartment) is closed, i.e., the deck OPEN detection signal (DOPD) is
‘0’.
• The deck lifter upper limit detection signal (DLUL) is ‘0’ and, further, the deck lifter
position detection signal (DLPD) is ‘0’.
• The deck lifter motor drive signal (DLMON*) is ‘0’.
• The deck lifter UP signal (DLUP*) is ‘0’. As a result, the lifter starts to move up.
w Conditions for Moving Down the Lifter
• The deck (compartment) is open, i.e., the deck OPEN detection signal (DOPD) is ‘1’.
• The deck lifter lower limit detection signal (DLLD) is ‘0’ and, further, the deck lifter
position detection signal (DLPD) is ‘0’.
• The deck lifter motor drive signal (DLMON*) is ‘0’.
• The deck lifter UP signal (DLUP*) is ‘1’. As result, the lifter starts to move down.**Knowledge is time consuming, exhausting and costly for a trained Tech.**
