2-5-l DCU Setup
The DCU is used to diagnose Printer malfunctions.
The DCU harness wire(lOpin-todpin) is connected to the Printer engine via:
1) Engine Board connector, CN2 (4pins)
2) (Video) Controller Board connector, 56 (4pins)
Open the Printer’s side cover(=SIMM Cover) and remove the shield cover and connect the DCU
to connector 56 on the Controller Board.
2-5-2 DCU Error messages (LED Display)
If an error occurs, connect the DCU to the Printer. DCU messages will indicates malfunctioning
areas of the machine.

6. Special Circuit Description
6-l. Engine Control Board
6-l-l Main Parts
6-l-l-l Reset Operation
Reset circuit initializes CPU when power is turned on and prevents CPU from unstable operation caused by
unstable power source. It consists of comparator IC LM393, resisters and condensers which determine reset timing.
When dc 3.8V or higher voltage is applied to #3 pin of LM 393, RESET signal goes HIGH and CPU starts initialize
operation.
CPUPINRS
4 122ms l
6-l-l-2 Fuser Temperature Control
Fuser temperature control circuit reads thermistor voltage through CPU pin ##45 (P5.0) and turn on or off mser
through CPU pin #38 (P6.4) and transistor Q3 (KSC945) according to thermistor value. Thermistor is device whose
resistance changes according to temperature of heat roller. As temperature increases, the resistance of thermistor
decreases. LM393 is used for preventing heat roller from overheating.
57
6-l-l-3 Motor Driving Circuit
SLA7029M receives phase signal from CPU and generates plused signal for main motor driving and controls
driving currents through R5 and R6.
It adopts constant current unipolar driving method
6-l-l-4 Solenoid Driving Circuit
Solenoid controls the paper pick up clutch. It is operated on +24V and control signal from CPU #22 pin (P3.2).
Q4(KSC 1008) is driver transistor and D 1 (IN4003) protects Q4 from switching off noise pulse.

6-l-l-5 Cover Open Sensing
When cover is closed, CPU pin #48 (P5.3) is HIGH, Otherwise Pin #48 is LOW.
58
6-l-l-6 Sensor
There are three sensor - Feed Sensor, Exit Sensor and Paper Empty sensor.
1) Feed Sensor
Feed sensor type is Photo Sensor. Feed sensor is connected to CPU pin #46 (P5.1) through R15. If paper is on
feed sensor, sensor state is LOW, otherwise sensor state is HIGH.
2) Exit Sensor
Exit sensor type is leaf switch. Exit sensor is connected to CPU pin #47 (P5.2) through R30. If paper is on exit
sensor, sensor state is LOW, otherwise sensor state is HIGH.
3) Paper Empty Sensor
Paper empty sensor type is Photo sensor. Paper empty sensor is connected to CPU pin #/49 (P5.4). When there is
no paper in cassette, sensor state is HIGH, otherwise sensor state is LOW.

6-I -2 Interface Specification
6-1-2-1 Overview
SAMSUNG LASER BEAM PRINTER (called ENGINE) can be comected to the image control device (called
CONTROLLER) with the interface through which they check their status and control the printing sequence and
image data. The ENGINE transposes the received image data from the CONTROLLER into visible image on paper.
There are two kinds of interface signal as follows.
1) STATUS SIGNAL
/READY indicates whether the ENGINE is ready to print, or not.
/CMSG is the command data from the CONTROLLER, /EMSG is the status data from the ENGINE as response
for the command data. Both are controlled by /CCLK, /CBSY, and /EBSY signals.
2) IMAGE SIGNAL
PRINT makes the ENGINE pick up a paper to print the image data from the CONTROLLER.
The synchronized image data (called /VDATA) by /PSYNC vertically and /HSYNC horizontally is sent to the
ENGINE by video clock of the CONTROLLER.
/EXITPAP indicates that the previous paper clears the exit sensor.

6-2-3 Fuser Control circuit
Fuser controlled by the “fuser on” signal.
When the mser on signal rises triac in the Photo Triac
(pc151) is turn on.
Then trigger input signal supplies into the gate of the
Triac (QlOl), Triac is turn on.

Clutch
6-2-4 Switching control
When power is turn on, starting current flows into the UlOl(pin6) passing through ZDlOl(R106)
The It’s totem-pole output can directly drive the MOSFET(Q102).
If the supply voltage drops, the IC shuts its output down when VCC=8.7V.
When the under voltage lockout circuit operates, the CS pin goes low to reset the IC.
Refer to power device data book (related document).

THV Control Block Diagram
THV output is constituted ‘I+” output and “-” output. “-” output is for clean the OPC drum. “+” output use is for
draw toner on the paper.
When the THV enable is low, the switching TR (Q202) is turned on and “-” output is generated. Soon the switching
TR (Q203) is supplied PWM input, “+” output is duplicated to “-” output in accordance with 4203 turn on.
The fundamental principle of the BIAS/MHV output control is similar to the THV output control.
