Toshiba 1550, 1560 Schematic

COPIER TOSHIBA 1550/1560.

13.6 Explanation of Circuits

13.6.1 Interface signals
[A] Signals from the copier to the paper feeding unit (PFU):

(1) RGT-CLT2

Drives the transport roller clutch.
When the signal is "L", the clutch (RGT2-CLT) energizes.

(2) PKUP-CLT2

Drives the pick-up clutch.
When the signal is "L", the pick-up roller clutch (PKUP2-CLT) energizes.

(3) FED-CLT2

Drives the paper feed roller.
When the signal is "L", the clutch (FED2-CL T) energizes, causing the paper feed roller to start rotat­ing.

(4) MOT-ON2

Rotates the drive motor.
When the signal is "L", the drive motor (PFU-MOT) starts rotating.

[B] Signals from the paper feeding unit (PFU) to the copier:

(1) CST2 (installation)

Tells the copier that PFU is installed. The signal becomes "L" with PFU installed.

(2) DR-SW2 (door switch)

Indicates whether or not the PFU's side cover is open. When the cover is closed, the door switch is
turned on, causing the signal to become "L".

(3) FED-SW2 (paper stop switch)

Indicates the status of the PFU's paper stop switch. When there is paper on the paper stop switch, it
is turned on, causing the signal to become "H".

(4) EMP-SW2 (paper empty switch)

Indicates whether or not there is paper in the PFU's cassette. When there is paper, the paper empty
switch is turned on, causing the signal to become "L".

(5) SIZ13 - 10 (Paper size switches)

Indicate the size of the cassette. When the size mark plate pushes the switches, the corresponding
paper size signal becomes "L".

13.6.2 Driving of the drive motor

The drive motor M10 (PFU-MOT) is driven by transistor Q1 as described below:

1

When the signal MOT-ON2*

from the copier becomes "L", an "L" voltage is applied to the base of Q1, Q1
is turned on, causing current to flow from +24VfQ1's emitterfQ1's collectorfR3fDG. This will cause
the drive motor M10 (PFU-MOT) to rotate. When the MOT-ON2 signal becomes "H", Q1 is turned of f,
shutting off the above current route. But while the motor continues to rotate due to its inertia, current also
tries to continue to flow, causing a voltage to be generated between the input and output terminals of the
motor. Since this voltage is applied between the anode and cathode of D1, the inverse electromotive
voltage occurring in the motor is short-circuited and restricted.

*1: The MOT-ON2 signal is to cause the motor (PFU-MOT) M10 to rotate and is supplied by the copier.

When this signal becomes "L", the motor starts rotating.
