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.
Table 2-2. CR Motor Specifications
Item Specifications
Type DC motor with brushes
Drive voltage +42V ± 5% (voltage applied to driver)
Armature resistance 23.6Ω ± 10%
Inductance 17.5mH ± 25%
Drive method PWM, constant-current chopping
Drive IC A6628
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 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.
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.
OPERATING PRINCIPLES Printer Mechanism 23
EPSON Stylus Photo 1400/1410 Revision A
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.
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 OffRange Thinning Out Control to make a further correction to the off-range
margins.
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.
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.
OPERATING PRINCIPLES Printer Mechanism 24
EPSON Stylus Photo 1400/1410 Revision A
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.

2.2.3.2 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.

2.2.6 Ink Sequence
The following ink sequence is executed according to various timer, counter, flag and
other information saved on the EEPROM.
Initial Ink Filling
When the printer is powered on for the first time after purchase, the printer
executes the initial ink filling operation to fill the ink cavities of the Head with ink.
When the initial ink filling operation is performed properly, the printer clears the
flag in the EEPROM so that initial ink filling operation will not be performed
when it is powered on the next time. The Stylus Photo 1400/1410 requires about
170 seconds to perform the initial ink filling operation.
If the sequence does not end normally during initial filling, the initial filling flag is
not cleared and the CL operating flag is set. Because of these flags, when powered
on the next time, the printer assumes that it was powered off for some reason
during initial filling and executes CL3 instead of the initial filling sequence. (On
the previous model, initial filling was executed again. However, when this
operation was performed, ink was wasted and therefore CL3 is executed to cover
for the ink filling performance.)
When the initial filling flag is set and the CL operating flag is not set, the printer
judges that the initial filling was not executed at all (power was switched on but
the cartridges were not installed), and when the printer is powered on the next
time, it executes initial filling.
Replacement Cleaning
Replacement cleaning is executed when an Ink Cartridge(s) is replaced.
OPERATING PRINCIPLES Printer Mechanism 33
EPSON Stylus Photo 1400/1410 Revision A
Manual Cleaning
This printer provides three different manual cleanings to remove ink coagulated by
air bubbles, viscous material, or foreign matter. Perform the following manual CL
operations by operating the panel or using the utility included in the printer driver.
Independently of the printing path after the previous CL, perform manual CL from
CL1 to CL3 in order if the cumulative printing timer counter is less than 9 minutes.
When the cumulative printing timer counter is more than 9 minutes, only CL1 is
executed.
Wiping Operation
Clean the nozzle surface, with the right-half of the rubber part on the wiper.
Flushing Operation
Prevent color mixture. Stabilize the ink surface inside the nozzles.
In addition, the printer determines which CL to perform according to the
remaining amount of ink in the Cartridge. When the printer detects the amount is
low, it automatically choose the CL that uses ink less than the other CLs. If the
remaining amount of ink is extremely low (Ink Low or Ink End status), the printer
disables the all the manual cleanings and indicates the status on the STM3.
2.2.7 Power-On Sequence
The following describes the printer operation after it is powered on.
When the Carriage Unit is in the Home Position with the CR Locked
1. After power-on, the drive of the APG Motor is transmitted to the Carriage Shaft,
and the PG position changes from PG Typ. to PG++.
2. The drive of the CR Motor is transmitted to the Carriage Unit, and the Carriage
Unit performs HP detection operation in the following path.
Home position ⇒ Right frame ⇒ CR Lock confirmation position
⇒ Right frame ⇒ Home position
3. The drive of the Pump Motor is transmitted to the Cap Unit, the Cap opens
(lowers), and the CR Lock is released.
4. After the Carriage Unit has moved to the left by the specified number of steps, the
Wiper, driven by the Pump Motor, performs the following.
Timer Cleaning
Ink is consumed depending on the combination of the cumulative printing timer,
cumulative cleaning count and cleaning timer.
Flushing
There are two types of flushing.
Flushing before printing
This is performed to reduce the viscosity of ink in the Printhead nozzles
before starting to print.
Scheduled Flushing
This is performed to prevent ink in the Printhead nozzles from increasing its
viscosity during printing.
Wiper setting ⇒ Wiper resetting
5. The Carriage Unit returns to the home position, and the PG position returns from
PG++ to PG Typ.
6. The drive of the PF Motor is transmitted to the PF Roller and Paper Eject Rollers
(front and rear) to rotate them for predetermined steps.
7. After moving between the left and right frames twice, the Carriage Unit moves to
the right end of the Front Paper Guide.
8. The PF Roller and Paper Eject Rollers (front and rear) rotates.
9. The Carriage Unit returns to the home position and is secured by the CR Lock.
OPERATING PRINCIPLES Printer Mechanism 34
EPSON Stylus Photo 1400/1410 Revision A
When the Carriage Unit is Out of the Home Position

Motor is transmitted to the Carriage Shaft, and the PG position changes to PG++.
2. The drive of the CR Motor is transmitted to the Carriage Unit, and the Carriage
Unit returns to the home position at slow speed.
3. The drive of the PF Motor is transmitted to the PF Roller and Paper Eject Rollers
(front and rear), which then rotate for about 2 seconds.
