2.2 Printer Mechanism
In common with previous model, this printer uses DC motors and stepping motors as
power source. The following table describes the motor types and their applications.
The basic mechanism is the same as the Stylus Photo R1800.
Figure 2-1. Printer Mechanism Outline
Table 2-1. Motors
Motor Name Type Applications/Functions
CR Motor DC motor with brushes
Drives the Carriage. Makes very little driving
noise. Controlled by the CR linear scale and CR
encoder sensor.
PF Motor DC motor with brushes
Drives the paper feed roller for the fixed-value
paper loading or the paper feed/eject operation. To
grasp the paper feed pitch, the precision gear
surface is fitted with the PF Scale and the PF
Encoder Sensor is used to control the motor.
APG Motor DC motor with brushes
Drives the Carriage Unit at the time of PG setting.
The two APG Sensors and Carriage Shaft are
driven vertically to control the motor.
ASF Motor
4-phase, 48-pole PM type
stepping motor
Drives the paper feed operation of the ASF. Since
this is a stepping motor, no scales or photo sensors
are required to grasp the driving conditions.
Pump Motor
4-phase, 48-pole PM type
stepping motor
Drives the pump, wiper, etc. of the Ink System.
Since this is a stepping motor, no scales or photo
sensors are required to grasp the driving
conditions.

2.2.1 Carriage Mechanism
The Carriage mechanism consists of parts/units such as the Carriage Motor (CR
Motor), Carriage Shafts, Platen Gap Adjustment Mechanism and Carriage Lock
Mechanism.
2.2.1.1 Carriage Mechanism
The following indicates the specifications of the CR motor (DC motor) that drives the
Carriage.
Closed loop control based on the CR Motor (DC Motor) and CR Encoder Sensor has
advantages in stabilized print quality and silent operation.
Heat Generation Control
The printer has a mechanism to reduce the variations in the torque constant and
coil resistance of the DC motors, and variations in output voltage of the Power
Supply Board to obtain a designated heating value.
CR Variation Measurement Sequence
The variations mentioned above are measured in a CR variation measurement
sequence when the CR mechanical load is in the initial status and saved into the
EEPROM. According to the saved information, the printer controls the drive
voltage to obtain a designated driving current. This minimizes the unit-to-unit
variation.
CR Measurement Sequence
To set the appropriate drive current value according to the CR mechanical load,
the mechanical load is measured in a CR measurement sequence and saved into
the EEPROM at power-on or after replacing the Ink Cartridge(s).
The above control and sequences correct the drive current value of the CR Motor
according to not only the mechanical load but also the variations of the motors. In
addition, the resultant CR drive current value is used to calculate a heating value, and
when the specified heating value is reached, wait time is provided per CR path for
printing.

2.2.1.2 Carriage Home Position Detection
As in the previous model, the Carriage Home Position is detected using the drive
current of the CR Motor and the speed/position signal of the CR Linear Encoder.
The basic home position detection sequence is described below.
1. The CR linear encoder pulse counter in the CPU is reset by the initialization
operation performed at power-on.
2. When the CR Motor rotates counterclockwise, the Carriage Unit moves from left
to right. When the following conditions are satisfied, the CPU assumes that the
Carriage Unit made contact with the right frame.
The ASIC detects 935/1500 counts or more in the PWM output under CR
Motor load positioning control.
P1 (number of output pulses from when the power is switched on till the
Carriage Unit makes contact with the right frame) is 19 steps or less.
3. When the CR Motor rotates clockwise, the Carriage Unit moves from right to left.
When the following conditions are satisfied, the CPU assumes that the Carriage
Unit reached the CR lock confirmation position.
The ASIC detects 600/1500 counts or more in the PWM output under CR
Motor load positioning control.
A difference between P1 and P2 (number of output pulses from when the
Carriage Unit made contact with the right frame until it reaches the Carriage
lock confirmation position) is 19 steps or less.
4. When the CR Motor rotates counterclockwise to move the Carriage from left to
right and the CPU detects 935/1500 counts or more in the PWM output under CR
Motor load positioning control, the printer judges that the Carriage has moved to
the far right position (in contact with the right frame).
5. When a difference between P1 and P3 (number of output pulses from when the
Carriage Unit reached the Carriage lock confirmation position until it makes
contact with the right frame) is 4 steps or less, the printer judges that the Carriage
Unit is in the home position.
IC9 (CPU-ASIC) sets the drive current value adequate for the Carriage Unit motion
and outputs it to the motor driver.
Based on the signal output from IC9 (CPU-ASIC), IC11 (Motor Driver) outputs the CR
Motor drive current to the CR Motor.
2.2.1.3 Sequence Used for PW Detection
The PW (paper width) Sensor installed on the bottom of the Carriage Unit is used to
control the printer according to various sequences.
The following briefly describes the operating principle of the PW Sensor.
A dark voltage is measured by the PW Sensor in three places at the right flat area (area
without the absorber) on the Front Paper Guide every time the printer is turned on, and
the measurement values are saved into the EEPROM as threshold values.
Threshold value detection voltage: Paper present
Threshold value detection voltage: Paper absent
The following sequences are performed.
Detection of Left and Right Edges of Paper Control
Before Printing
The printer sets the print range according to the paper-size information from
the Driver and the actual paper-size detected by the PW sensor.
During Printing
When executing a borderless printing, the printer sets the off-range margins
by detecting the paper edges with the PW Sensor. When the resolution is 1440
x 1440 (VSD3) or 2880 x 1440 (VSD3) dpi, the printer performs the Off-
Range Thinning Out Control to make a further correction to the off-range
margins.
Detection of Top Edge of Paper Control
Before starting a print job, the printer detects the top edge of a loaded single sheet
of paper to set the off-range top margin. (Only when not detecting the top edge of
paper with the PW Sensor.)
Detection of Bottom Edge of Paper Control
After starting a borderless printing, the printer sets the off-range bottom margin.
Detection of Edges of CD-R Control
Before starting to print, the PW Sensor detects top, bottom, left and right edges of
the CD-R. See Section 2.2.3.3 CD-R Printing Mechanism on page 29.
EPSON Stylus Photo 1400/1410 Revision A
OPERATING PRINCIPLES Printer Mechanism 25
Detection of CD/DVD Tray Control
Before starting to print, determines the type of media.
PW sensor dark voltage (VH) measurement
PW sensor dark voltage (VH) measurement is performed at the following timings
and locations and used to calculate the threshold value of whether paper is present
or not.
CD/DVD Tray
When printing on a CD-R, the dark voltage is measured on the CD/DVD tray,
and the threshold value (VS) is then calculated and saved in the EEPROM
area as a PW detection level.
• Threshold value detection voltage: CD-R present
(tray home position detected)
The measurement voltage in the presence of the CD-R is saved into the
EEPROM as a white level. The white level value is used to check the sensor
deterioration condition on occasions such as servicing.
• If the measurement value of the white level is close to that of the PW
detection level, it means that the sensor is dirty or deteriorated.
2.2.1.4 APG (Auto Platen Gap) Adjustment Mechanism
The following indicates the specification of the DC motor that drives the APG adjuster.
The APG Motor (DC Motor) and two APG Sensors drive the PG Cam to automatically
adjust the PG amount according to the paper.

2.2.3.1 ASF Paper Feeding Mechanism
The following shows the specifications of the stepping motor that drives the ASF Assy.
Driven by the ASF Motor, the ASF Assy performs the following feeding operation.
1. When a paper feeding command is issued from the PC or the Paper button of the
panel is pressed after power-on, the driving force of the ASF Motor begins to be
transmitted to the LD Roller following the route shown below.
2. When the LD Roller starts rotating, the flag of the ASF Sensor Wheel comes free
from the notch on the ASF Sensor. At the same time, the Paper Back Lever
becomes free from the Cams located at the left and right ends of the LD Roller,
then the Paper Holder on the Paper Back Lever inclines downward by tensile force
of the Paper Back Lever Torsion Spring.
3. By the LD Roller's rotation, the Hopper is released from the Hopper Cams located
on the left and right ends of the LD Roller, and the Hopper pops up by tensile force
of the Hopper Compression Spring.
4. When the next sheet of paper is fed by the LD Roller and the Retard Roller, the
Hopper is pressed against the Frame again by the Hopper Cams, and the Paper
Holder of the Paper Back Lever rises by the Cams on the left and right ends of the
LD Roller to prevent the next sheet from being fed with the previous sheet.
5. The LD Roller stops to rotate when it makes one revolution and the flag of the
ASF Sensor Wheel returns to the ASF Sensor.

2.2.3.2 CD/DVD Tray Base Lock Mechanism
To prevent the Printhead from being damaged by mistake, the printer is designed to
lock the CD/DVD Tray Base when the Carriage Unit is out of its home position.
The following explains the lock mechanism of the CD/DVD Tray Base.
Lock Release Sequence
1. When the Carriage Unit returns to its home position, the Pump Motor drive is
transmitted to the Paper EJ Lock Release Cam.
2. The salient of the Cam presses down the Paper EJ Transmission Lock Lever
to release the tab of the Paper EJ Lock Lever from the Paper EJ Transmission
Lock Lever.
3. The CD-R Release Lever comes free from the Paper EJ Lock Lever and
comes down to enable the CD/DVD Tray Base to open.
When the Carriage Unit is out of its home position, the salient of the Paper EJ Lock
Release Cam does not press down the Paper EJ Transmission Lock Lever, and the tab
of the Paper EJ Lock Lever is not released. Therefore, the CD/DVD Tray Base cannot
be opened.

2.2.3.3 CD-R Printing Mechanism
CD/DVD Tray Home Position Detection Sequence
The following sequence is performed after opening the Front Cover (CD-R
Sensor: closed), inserting the CD/DVD Tray to the specified position, and pressing
the Paper button.
When the close signal of the CD-R Sensor is detected, no paper is fed from the
ASF even if the Paper button is pressed. In this case, pressing the Paper button
executes a CD/DVD Tray home position detection sequence.
1. When the APG Assy is driven, the PG position is set to “++” and the Driven
Roller of the Upper Paper Guide presses onto the CD/DVD Tray.
2. When the Carriage Unit moves to the left and the PW Sensor detects the CD-
R, the Carriage Unit returns to its home position (HP).
3. After waiting for about 5 seconds at the HP, the Carriage Unit moves to the
CD/DVD Tray HP detectable position (right end of the CD/DVD Tray).
4. The CD/DVD Tray is pulled towards the ASF, the PW Sensor detects the CD/
DVD Tray HP, and then the Carriage Unit moves to the center of the CD/
DVD Tray.
5. When the PW Sensor detects the white marking in the center of the CD/DVD
Tray, the CD/DVD Tray is fed in the paper ejection direction.
6. The Carriage Unit moves to the left, the PW Sensor detects the white marking
on the left, then the Carriage Unit moves to the right, and the PW Sensor
detects the white marking on the right.
7. The Carriage Unit moves to the center of the CD/DVD Tray, and the PW
Sensor starts detection of the front and back direction of the CD-R. After the
front end of the CD-R is detected, the CD/DVD Tray is fed towards the paper
ejection direction, and the back end of the CD-R is detected. After that, the
CD/DVD Tray is fed to the center of the CD-R in the paper ejection direction.
8. The Carriage Unit moves to the left, and the PW Sensor starts detection in the
horizontal direction of the CD-R. After the left end of the CD-R is detected,
the Carriage Unit moves to the right, and the right end of the CD-R is
detected.
9. The Carriage Unit stops after moving to the CD/DVD Tray HP detectable
position, then the CD/DVD Tray is fed towards the ASF.
10. When the CD/DVD Tray stops operating, the Carriage Unit moves to the
carriage HP and stands by.
If the CD/DVD Tray HP, the white marking, or the CD-R cannot be detected within the
steps predetermined for the CD/DVD Tray HP detection sequence, the CD/DVD Tray
is ejected and Paper Out Error is displayed.
