Chapter 2Description of Operation
z Paper Feed Unit ......................................... 18
The paper loaded on the feed tray is raised by the
elevator motor. When the paper is in the required
position, a jet of air from a fan in front of the paper
causes several sheets of paper to rise up. The suction
unit pulls up the top sheet only, and then the feed motor
drives the suction belt to transfer the paper.
When the paper from the AF-100 reaches the PPS1 in
the DC-545, the paper is transferred to the paper path by
the press roller and the feed stepping motor.
A separator mechanism is used to prevent two or more
sheets from being transferred at one time.

2. Operation
1) Processing starts (processing does not start if there is no paper).
The fan (blower) and the fan (suction) start running.
2) The feed tray starts rising.
3) The feed tray stops when the paper level sensor turns on (light is not transmitted).
4) The shutter solenoid operates and the shutter opens and the paper is sucked onto the suction unit.
5) The feed motor starts and the suction belt begins turning to transfer the paper.
6) The feed motor stops when the paper reaches PPS1 (light is not transmitted).
If paper does not reach PPS1 within about 2.5 seconds, the elevator falls repeating operations 3) to 5) until
the paper level sensor turns off (light is transmitted). If the operation is repeated three times before the paper
reaches PPS1, a J2: FEED JAM error occurs and the machine stops.

3. Operation of each unit
(1) Fan (blower)
Description
Paper on the feed tray is transferred to the blower and several sheets are floated up.
The airflow of the blower is adjusted by changing the position of the shutter and fan unit.
The level the paper is floated up is adjusted by changing the airflow of the blower and the paper level sensor.
The fan (blower) is usually running during processing.
Operation
The blower airflow can be increased by turning the knob so the numbers increase.
The gap between the shutter and the fan increases, which increases the air intake and therefore increases the
amount of air blown out.
The blower airflow can be decreased by turning the knob so the numbers decrease.
The gap between the shutter and the fan decreases, which decreases the air intake and therefore decreases the
amount of air blown out.

Description
Because the fan (suction) is running during processing,
when the shutter solenoid is on, the topmost sheet of
paper on the feed tray is sucked on to the suction unit.
The feed motor starts running about 0.3 seconds after
the shutter solenoid turns on, and the suction belt turns
and transfers the paper to the DC-545.

(5) Separator Gap
Description
The separator gap is a mechanism between the separator
and the suction belt that allows paper that is sucked on
to the suction unit to be transferred one sheet at a time
to the paper path.
This gap is regulated by turning the knob to raise and
lower the separator.
Turn the knob so that the numbers increase to make the
gap narrower. The separator rises and the gap narrows.
Turn the knob so that the numbers decrease to make the
gap wider. The separator falls and the gap widens.
Raise the separator if the paper being transferred is
double feed.
Lower the separator if paper is mis-feeding.

(6) Elevator Motor
Description
The elevator motor raises and lowers the feed tray.
When there is no paper on the feed tray, the feed tray
lowers until it triggers the elevator lower SW.
However, if paper is loaded on the feed tray while it is
lowering (paper sensor is not transmitting light), the
elevator motor stops and the feed tray stops lowering.
The feed tray rises until the paper level sensor is on
(light is not transmitted) while paper is being fed.
During a paper feed retry operation, the feed tray
continues to lower until the paper level sensor goes off
(light is transmitted) for a period. Then the feed tray
rises until the paper level sensor goes on (light is not
transmitted).
If paper does not reach the elevator upper switch,
elevator lower switch, or paper level sensor after a set
time (*) after the elevator operation, an E8: ELEVATOR
ERROR occurs.
* 10 seconds when rising at start, 3.5 seconds during
paper feed operations, 9 seconds when lowering at

x CCD Mechanism
1. Description
The CCD mechanism reads the bar code and register
mark on the paper that is being processed and transfers
the data to the main P.W.B. unit.
The job is automatically selected according to the bar
code (code 39) and the register mark compensates for
incorrect printing positioning.
2. Operation
1) When the paper feeding operation is finished, the
CCD starts reading the bar code.
If the data transfer between the CCD and the main
P.W.B. is not done correctly, then E2: RS232C
ERROR is displayed and the machine stops.
If bar code is off go to Step 4.
\See page 135
2) Data is transferred to the main P.W.B. after the bar
code has been read.
If, when reading starts, the paper is transferred
50 mm but the bar code could not be read, then E3:
BARCODE ERROR is displayed and the machine
stops.
\See page 135
3) The job is set based on the data in the bar code.
4) The machine is in standby until each slitter has been
moved.
If register mark is turned off go to Step 9.
5) The front edge of the paper backs up to PPS2
temporarily.
6) The CCD starts to read the register mark.
7) The amount of compensation is calculated after the
register mark has been read.
If the register mark can not be read even though the
paper has been transferred 40 mm after reading has
started, then E4: REG. MARK ERROR is displayed
and the machine stops.

b Creaser Unit
1. Description
The paper is creased vertically in relation to the direction the paper is moving.
One crease can be done in approximately 1.5 seconds.
Turning on the power starts the creaser motor in standby in the home position.
2. Operation
1) Main transfer stops temporarily when the paper reaches the crease position.
2) The creaser motor starts and cutting begins.
3) The creaser motor stops when the creaser position sensor goes from off to on, and the main transfer starts
again. If the creaser position sensor does not change (if light is transmitted then it continues to transmit) 2.0
seconds after the creaser motor starts running, then J8: CREASE LOCK is displayed and the machine stops.

2. Operation
1) After paper stops being fed (after the Feed Stepping Motor stops) the Main Motor starts running and the
paper is transferred to the paper path section.
2) The paper stops temporarily at the CCD and then continues being transferred. If read BAR CODE
(REGISTER MARK) has been set, then the paper continues being transferred after the BAR CODE
(REGISTER MARK) has been read.
3) Main motor stops temporarily when cutting and scoring. When cutting and scoring have finished, transfer
starts again, and stops a short period after the paper is ejected.
The below two conditions cause J3: CENTER JAM to be displayed, and the machine to stop.

This machine uses code 39 bar code.
Example: The bar code for P-11 is shown below.
The DC-545 can use this bar code if it is converted to CODE-39.
If the bar code comes in the following range, the CCD automatically replaces the data and sends the data (pre-
set no.) to the DC-545.

⁄1 REGISTER MARK
Mark 1
1) The paper is transferred in increments of 0.1 mm
from PPS2, and the mark is read by the CCD.
2) When the edge of the reg. mark is detected, the
reference clock count in the CCD is stored in the
buffer in the microcomputer.
3) After another 0.1 mm is transferred, it is compared
with the clock count before the position of the edge is
detected, and if it is within a fixed range, the count is
then +1, and the reference clock in the CCD is stored
in the microcomputer buffer (up to 10 items). The
count is cleared if it is outside the range.
4) When the counter reaches 45 (the edge is the same
for 4.5 mm) the value for the mark is the average of
the values of the 10 values for the reference clock in
the buffer in the CCD.

OK even if it is not the edge), if the counter is not +1,
the counter goes to 0 and returns to Step 1.
3) The position of mark 2 is determined as 1.0 mm
