Though the Stylus PHOTO 2100/2200 is similar in basic structure of the mechanism to
the Stylus PHOTO 2000P, it has the following features.
• For compatibility with CD-R label direct printing, the CD-R tray adaptor and
exclusive sensor are loaded. (Only for Stylus PHOTO 2100)
• To feed board paper and roll paper, the exclusive paper feed guide is fitted.
• For compatibility with the CD-R tray and correction of ink transfer to the roller, the
newly designed paper eject unit is provided.
Used for carriage driving. Makes little noise during
driving. The CR linear scale and CR encoder sensor
are used to control the motor.
Power source to drive the Paper loading rollers a t the
time of fixed-value paper loading or 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.
Drives the pump and performs paper feed operation
from the ASF. Because of a stepping motor, this
motor does not require a scale, photo sensor and like
to be fitted to grasp the driving conditions.

2.2.1 Carriage Mechanism
The Carriage mechanism consists of the Carriage motor (CR motor), Carriage guide
shafts A (main shaft), B (sub shaft), Platen gap adjustment mechanism, Carriage lock
mechanism, and others.
2.2.1.1 Carriage Motor (CR Motor)
Like the one of the conventional Stylus PHOTO 2000P, the Carriage mechanism of
this product uses a DC motor as a drive source. The following indicates the Carriage
driving DC motor specifications.
Table 2-2. CR Motor Specifi ca tions
ItemSpecifications
TypeDC motor with brushes
Drive voltage+42V +/- 5%(voltage applied to driver)
Winding resistance23.0Ω +/- 15%
Inductance24.0mH +/- 25%
Drive methodPWM, constant-current chopping
Drive ICA3958
The CR motor of the conventional model uses a stepping motor, and the carriage unit
position was controlled by open loop control. To stabilize the printing qual ity and
ensure silent operation, however, this product adopts the DC motor and linear encoderbased closed loop control like the Stylus PHOTO 2000P to control the Carriage speed
and position. Also, the conventional DAC control was changed to PWM control.
Simultaneously, the basic signal (PTS signal) is generated to time ink discharge.
Driven by the CR motor, the Carriage unit moves within the printing area along the
Carriage guide shaft of the printer mechanism during printing.

Figure 2-2. Carriage Mechanism
Using low-cost DC motors, this product grasps the variations of the torque constants,
coil resistances and power supply board output voltages of the individual DC motors
adequately to carry out heat generation control according to individual differences.
The variations of the torque constant, coil resistance and power supply board output
voltage of the motor are measured in a CR variation measurement sequence when the
CR mechanical load is in the initial status (Max. 150g.cm) and saved into the
EEPROM (AC<H>). According to the variations (individual differences) measured in
this sequence, the voltage is corrected to make the drive current value constant
(without an individual difference) according to the variations (individual differences)
measured in this sequence.
Further, to set the appropriate drive current value according to the variation of the CR
mechanical load, the mechanical load is measured in a CR measurement sequence and
saved into the EEPROM 6C<H>, 6D<H> in a power-on or IC change sequence.
However, if 14 is saved at the EEPROM 6C<H> and 05 at 6D<H>, Fatal error will
occur since too large load is applied to the CR drive system.
Accordingly, not only the mechanical load but also the variations of the motor and like
are taken into consideration to correct the drive current value of the CR motor. In
addition, a heating value is calculated from the CR drive current value, and when the
specified heating value is reached, wait time (0.3s to 7.9s) is provided per CR path for
printing.

2.2.1.2 Carriage Home Position Detection
To detect the Carriage home position, the drive current of the CR motor and the speed/
position signal of the CR linear encoder are used as in the conventional Stylus PHOTO
2000P.
The basic home position detection sequence is as descri bed 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 moves from left to
right. When the following conditions are satisfied, the CPU assumes that the
Carriage made contact with the right frame.
2.1 When the ASIC detected 750/1500 counts or more in the PWM output

2.2.1.3 Sequence Used for PW Detection
The PW detector on the Carriage unit bottom performs the following sequence.
! Off-paper printing prevention control
Before start of printing (immediately after the end of paper locating) or during
printing, whether paper is present or not is detected to prevent off-paper printing
onto the Paper guide. (Applied to only the left or right end of the paper)
If the sent data has the paper size that is larger than the fed paper size, trimming is
executed according to the paper size detected by the PW sensor, and frame
printing is performed (frame width 2mm). Reversely, if the received data has the
paper size that is smaller than the fed paper size, frame printing is also performed.
This feature is designed to prevent off-paper printing onto the Paper guide by
frameless printing performed in a wrong using method. However, in the fast mode
for plain paper or postcards, paper width detection is not executed to improve the
throughput. When the above using method is performed, the specifications of
trimming and frame printing are not applied.
! CD-R center detection control (Only for Stylus PHOTO 2100)
When printing is not being performed, the PW detector is used to detect the center
of CD-R.
Refer to 2.2.3.6 "CD-R Printing Mechanism (Only for Stylus PHOTO 2100)" for
details.
! Board paper/roll paper leading edge detection control
Control exercised to detect the user-preset board paper leading edge, or control
carried out to detect the roll paper edge. Therefore, the PW sensor does not detect
a paper leading edge at the time of ASF cut sheet feeding.
! Off-range restriction control
At the time of frameless printing, a paper leading edge is detected using the PW
detector to restrict the frameless off-range amount.
" Auto sheet feeder complete frameless mode
In the complete frameless mode, control is performed to print the print data
3mm larger at top, 5mm larger at bottom, and 2.5mm lager at left and right
than the detected paper size.
(3mm larger at top, 5mm larger at bottom, and 3.5mm lager at left and right
for A3 or A3+ size)
" Roll paper mode
In the left and right frameless mode, control is performed to print the print
data 2.5mm lager at left and right than the detected paper size.
(3mm larger at top, 5mm larger at bottom, and 2.5mm lager at left and right
when the fixed-format mode is selected)
! 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 whethe r pap er is pr esent
or not.
" Cut sheets, Roll paper
The dark voltage is measured and updated at every power-on, and the
threshold value (VS) is calculated and saved in the EPROM 76<H> area as a
PW detection level. The dark voltage is measured at 3poinst on the left flat
portion of the the Paper Guide Front. If the PW level measured in the Papaer
width measuerment sequence is less than the PW detection level stored in the
EEPROM, it means the sensor is detecting the paper.
" CD-R tray (Only for Stylus PHOTO 2100)
When a CD-R is used, the dark voltage is measured on the CD-R tray, and the
threshold valve (VS) is then calculated and saved in the EPROM 76<H> area
as a PW detection level.
If the PW sensor level measured in the CD-R HP detection sequence & CD-R
center position detection sequence is less than the PW detection level stored in
the EEPROM, it means the sensor is detecting the HP of the CD-R tray and
the CD-R on the tray.
Every paper or CD-R tray is loaded, the voltage measured on the Paper or
CD-R tray is stored in the EEPROM BB<H> area as a white level.
OPERATING PRINCIPLESPrinter Mechanism43
Page 44
EPSON Stylus PHOTO 2100/2200Revision B
However, the white level value is not used in the PW sensor-related firmware
processing. The white level value is used to check the sensor deterioration
condition during servicing or like. 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.

2.2.2.3 Head Hot Error
If Head Hot occurred due to either of the following factors on the conventional printer,
the Ink End value was written to the Ink consumption counter and Ink End error was
displayed. This product displays Fatal error.
! Head Hot error factors
1.If more than half of all nozzles are clogged and cannot discharge ink, ink will
not flow through the path, resulting in a Head Hot status.
2.If a multi-nozzle dropout attributable to a vertical fall or like occurs in more
than half of all nozzles, ink will not flow through the path, resulting in a Head
Hot status.
! Reason why Fatal error is displayed
If either of the above factors occurs, the conventional model that did not adopt the
CSIC displayed Ink End error at occurrence of Head Hot. Reason: A wrong Ink
End value was written to the Ink consumption counter by the ink cartridge
removing/inserting operations performed before the Ink End error. Because of
this, the Ink End error was adopted to prevent Head Hot that would be caused by
continuous off-paper printing since the printer could not recognize an Ink End
status if the Ink cartridge is in that status.
On the model that adopts the CSIC, it is inconceivable that a wrong Ink End value
is written to the Ink consumption counter, and Head Hot occurs only due to the
above factors. However, when the nozzles are clogged, the chances that the user
can restore it to normal are extremely remote, because if the user whose printer
resulted in Head Hot installs a new Ink cartridge, the Ink End value is written to
the Ink cartridge, and therefore, the printer will result in a Head Hot status again.
As a result, the Ink cartridge has no problem but that Ink cartridge becomes
unusable. To avoid this, the hardest CL is executed automatically to return from a
multi-nozzle dropout in order to provide protection from the factor 2 at occurrence
of the Head Hot error. If the Head Hot error still persists, Fatal error is displayed to
prompt the user to send the printer to the repair center.

2.2.2.4 Pseudo Four-color Mode
This print mode can be selected in the detail setting mode when the plain paper is
selected, and means the draft mode.
In this mode, the printer operates as a pseudo four-color printer, with Lines A and B
used for one color of BK, Lines C and D for one color of C, Lines E and F for one color
of M, and Line G for one color of Y.
Therefore, since two lines of head nozzles are used as one color for each of BK, C and
M, 192 nozzles are used for each color and the printing resolution is 360 x 360dpi. For
Y, the resolution is 360 x 180dpi and 96 nozzles are used.
The JFK of the driver creates the four-color 360 x 360dpi mode and sends it to the
printer. For Y, however, the dot structures of the top and bottom lines are ORed to print
on one line.

2.2.3.3 ASF Paper Feeding Operation
Using the driving force transmitted from the ASF/Pump motor via the DE mechanism,
the ASF unit performs the following paper feeding operation.
To achieve stable paper feeding operation of the paper feeding mechanism of this
product, the double-feed prevention mechanism is installed in the ASF. To prevent
paper from dropping into the paper path from the paper setting position in the ASF
unit, the Paper return lever returns the paper to within the ASF hopper securely, and the
LD roller then starts paper feeding operation. Refer to the following steps for details of
the paper feeding operation including that of the double-feed prevention mechanism.
1.At power-on, the ASF/Pump motor rotates in the CCW direction and the ASF
home position is detected. Then, the ASF/Pump motor rotates in the CW direction
by the specified number of steps, thereby setting the LD roller and Paper return
lever in the paper feeding standby position. Refer to [Standby status] in Figure 2-7,
"Paper Feeding Operation".
2.When you give a paper feeding command from the PC and press the Paper switch
on the panel, the ASF/Pump motor rotates in t he CCW direct ion an d th e LD rol ler
starts paper feeding. Refer to [Paper feeding status] in Figure 2-7, "Paper Feeding
Operation".
3.When the paper is transferred from the ASF unit to the PF roller and detected by
the PE sensor, the LD roller stops in the position where the friction of the LD roller
is cleared. Refer to [PF roller passing status] in Figure 2-7, "Paper Feeding
Operation".
4.Then when you give a print command and press the Paper switch on the panel, the
ASF/Pump motor rotates in the CW direction by the specified number of steps,
thereby setting the LD roller and Paper return lever in the paper feeding standby
position. Refer to [Standby status] in Figure 2-7, "Paper Feeding Operation".

2.2.3.4 Manual Paper Feeding Mechanism (Board Paper)
To enable direct printing onto thick paper and CD-R label, this product has the
mechanism to feed paper from the printer front and rear manually.
Move the Release lever to the farthest position, insert thick paper from the rear manual
feed slot until its leading edge reaches a position about 1cm from the PF/Driven roller,
and set the Release lever in the thick paper mode.
When the PE sensor detects the paper after the above Release lever has been operated,
pressing the Paper feed switch causes the PW sensor to detect the leading edge of the
paper and the printer to perform paper locating control and enter the standby status.
2.2.3.5 Roll Paper Feeding
Since panel operation in the roll paper mode differs from the above operation, the
differences of panel operation after roll paper feeding will be described.
1.When roll paper is fed with the Release lever not in the release position, the PE
sensor detects the paper, and after 2 seconds has elapsed, the paper is fed.
2.The PW sensor check for the leading edge of the paper, and if it detects the paper,
the printer operates in the cutter self-cleaning mode.
3.The printer back-feeds the paper to the paper print starting position.
As explained above, when roll paper is inserted from the Roll paper feeding guide to
the paper feeding position of the PE sensor, paper is automatically fed and back-fed to
the print starting position. At this time, panel switch operation is invalid (since 02<H>
is written to 3F<H> in the EEPROM), and the definitions of the panel operation and
Paper feed switch differ between cut sheets and roll paper.
When roll paper is fed, 02<H> is written to the EEPROM 3F<H> area, but when roll
paper print data is received from the PC, 01<H> is written to the 3F<H> area. Panel
switch operation differs as described below between when 02<H> is written to the
3F<H> area and when 01<H> is written there.
! When 02<H> is written
Pressing the Roll paper cut switch for more than 3 seconds back-feeds the leading
edge of the roll paper to the PE sensor (the Paper LED blinks). When the roll paper
is removed from under the PE sensor in this state, paper is fed from the ASF.
! When 01<H> is written and cutter is fitted
When the data from the photo quicker is "No auto cut", pressing the Roll paper cut
switch after end of printing feeds the separation position in the print data to the roll
paper cut position and returns the leading edge of the paper to the print starting
position after paper cutting.
When the data from the photo quicker is "Standard 1 cut" or "Specific 2 cuts", the
roll paper is cut automatically at every separation of the print data, and the leading
edge of the paper is then returned to the print starting position.

! CD-R tray home position detection sequence
When the CD-R attachment is fitted, the Release lever setting position (PG sensor:
Close, Release sensor: Open) and CD-R tray sensor (Close) are detected. By pushing
the CD-R tray into the specified position and pressing the Paper feed switch in this
status, the following operation is performed.
1.The Carriage unit moves to the CD-R tray home position detection position (white
label position).
2.The CD-R tray is pulled in the ASF direction.
3.When the PW sensor of the Carriage unit detects the CD-R home position, the
Carriage unit moves to the CD-R tray center position (horizontal center of the
CD).
4.The CD-R tray is fed in the paper ejection direction and the trailing edge of the
CD-R is detected. Then, the CD-R tray is fed in the ASF direction again and the
leading edge of the CD-R is detected. After that, the CD-R tray is fed to the CD-R
tray center position in the paper ejection direction.
5.In the position in Step 4, the Carriage unit moves rightward and the detection of
the CD-R horizontal direction starts. After the left end of the CD-R is detected, the
Carriage unit moves rightward again and the CD-R horizontal direction is
detected.

the home position is detected, both the Carriage unit and CD-R tray stop operating
and are put in a standby status.
If the CD-R tray home position or CD-R cannot be detected in the specified step
operation of each step in the above sequence, the CD-R tray is ejected and Paper out
error is displayed. If the Release lever setting position (PG sensor: Close, Release
sensor: Open) and CD-R tray sensor (Close) are detected when the CD-R attachment is
fitted, pressing the Paper feed switch will not start paper feed from the ASF. In this
case, pressing the Paper feed switch performs the CD-R tray home position detection
sequence.
When the CD-R tray is detected, Release lever error is displayed if the Release lever
setting position is other than the CD-R position.

The driving force of the PF motor is transmitted to the PF roller and Paper eject rollers
in the following paths.
The following shows the part names and outline of the PF roller driving force
transmission path. With the driving force transmitted in above paths, paper is
transferred in the following path.
The paper fed from the ASF, Roll paper guide or Board paper guide is detected by the
PE sensor installed on the right side of the Upper frame, and its leading edge is
transferred to the center front of the Paper guide once.
To eliminate the deflection of the paper, the paper is then returned toward the ASF unit
by the specified number of steps according to the paper feed mode, and is transferred
again to the specified paper locating position toward the front of the Paper guide.

2.2.5 Ink System Mechanism
The Ink system mechanism consists of the Pump unit (including the Carriage lock
lever) and Capping mechanism. The Cap unit is in close contact with the CR unit and
drains ink from the Ink cartridge to Head cavities to Cap to Waste ink pad using the
driving force of the Pump unit.
2.2.5.1 Pump Mechanism
The Pump mechanism is designed to suck ink from the Printhead or Cap assembly. The
Cap assembly has a built-in head cleaning wiper. The following gives the operation
outline of the Pump mechanism.
To provide the driving force of the Pump mechanism, a 4-phase, 48-pole PM type
stepping motor is used as the ASF/Pump motor. For the specifications of the ASF/
Pump motor, refer to 2.2.3.1 Table 2-9 "ASF/Pump Motor Specifications".
When the driving force of the ASF/Pump motor is switched to the Pump unit side by
the DE mechanism, the functions of the Pump mechanism are as indicated in the
following table depending on the rotation direction of the ASF/Pump motor.

2.2.5.2 Drive Transmission Path to Pump Unit
1.The Carriage unit moves to the right end of the Carriage guide shaft to move the
DE lock lever to the right end.
2.The ASF/Pump motor rotates in the CW direction (as viewed from the motor
pinion side) by the specified number of steps.
3.As the ASF/Pump motor rotates in the CW direction by the specified number of
steps, the Planetary lever unit in the DE unit moves toward the Combination gear
17.19, 25.6.
4.As the CR unit moves leftward from the right end of the Carriage guide shaft by
the specified number of steps, the DE lock lever fixes the Planetary lever unit in
position.
5.The driving force of the ASF/Pump motor is transmitted in the following path.
Motor pinion gear → Planetary lever unit → Combination gear 17.19, 25.6 →
Tension belt → Combination gear 12, 29.92 → Spur gear 26.4 → Pump unit gear

The following diagram shows the pump operating principle.
1.When the Pump unit is rotated by the ASF/Pump motor in the CW direction, the
turning roller presses the tube. Therefore, ink is fed from the Cap unit toward the
Waste ink pad.
2.When the Pump unit is rotated by the ASF/Pump motor in the CCW direction, the
roller moves away from the tube and does not press the tube, and ink is not sucked.

2.2.5.3 Capping Mechanism
The Capping mechanism uses the driving force of the Pump unit to come into close
contact with the Head surface to suck ink from the Ink cartridges, Head and Cap,
thereby securing air tightness in the Cap. When the printer is in a standby status or its
power is OFF, the Capping mechanism is in close contact with the Head surface to
secure moisture retention in the Cap, preventing the Head from being clogged with ink
while the printer is stored. The following diagram shows the outline of capping
operation.

2.2.6 Ink Sequence
The following ink sequence is executed according to various timer, counter, flag and
other information saved on the EEPROM.
! CSIC-related sequence
The ink type 1 code stored in the CSIC memory chip is identical regardless of the
Japanese domestic or overseas cartridges, and is saved at the main board
EEPROM A0<H> - A7<H>.
If data is read from each color CSIC and Ink cartridge error is not displayed at
power-on, Ink end error is displayed. If the read data have no problems, the CSIC
data status is made valid.
After CSIC operation is checked, the ink consumption of the I/C currently
installed per color is compared with the ink consumption saved in the printer
EEPROM, and control is performed under the following conditions.
" When current I/C consumption differs (from ink consumption in EEPROM)
1.On the assumption that the I/C has been changed at power-off, the first I/C
flag is reset.
2.The installation count in the printer EEPROM is updated for the CSIC.
In the CSIC information replacement sequence, the CSIC side ink
consumption data is updated to the ink consumption data in the printer
EEPROM.
" When current I/C consumption is the same (as ink consumption in EEPROM)
1.When the initial filling flag is set and the CSIC side ink consumption is 0, the
printer judges that initial filling is not yet performed.
(The printer before initial filling judges that the I/C is fitted in a power-off
status.)
2.Installation count updating, CSIC information replacement, and initial filling
are executed in this order.
3.If the initial filling flag is not set, the printer judges that I/C change was not
made at power-off and regards the CSIC data as valid.
Data is written to the CSIC at power-off, in the power saving mode, at the time of
cartridge change, or at the time of cleaning.
1.Data is read from the CSIC and developed in the RAM on the main board.
2.The data is compared with the ink consumption in the printer EEPROM. If the
data are the same, the data is written to th e CSIC. If they are different, only
the consumed difference is added and written to the CSIC. When cleaning is
performed, the CL count is also written, and when the I/C is changed, the
installation count is also written.
3.The used model name data on the I/C side is rewritten.
Note: Reason why the used model name data is rewritten from the printer to the I/C:
To grasp which printer used the I/C removed.
4.After that, the change flag 2 (flag that indicates change CL) is set and CL is
executed. If the ink set (Line A, Line B) of the current I/C differs from the ink
set in the EEPROM, replacement CL3 is executed.

Initial ink filling
! Replacement cleaning, change cleaning
When the printer is powered on for the first time after the purchase of the product,
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 next. The Stylus PHOTO 2100/2200 requires
about 90 seconds to perform the initial ink filling operation and consumes about 1/
7 of the new monochrome ink cartridge.
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 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
conventional mode, initial filling was executed again. However, when this
operation was performed, ink was wasted and therefore CL3 is executed to cover
the ink filling performance.)
When the initial filling flag is set and the CL operating flag is not set, the printer
assumes that the initial filling was not executed at all (power was switched on but
the cartridges were not set), and when the printer is powered on next time, it
executes initial filling.
This product has three patterns of black ink combinations in Lines A and B. Refer
to Table 2-3 "Relationships between Nozzle Lines and Color Arrangement" on
page 44.
When the Carriage is within the home position and the ink types of Lines A and B
are changed within the above patterns during ink cartridge change, three different
replacement CLs are executed depending on the ink types to prevent mixture of
the old ink and new ink.
If the ink types of Lines A and B are not changed, change CL is executed instead
of replacement CL.
If the color of the ink after replacement is lighter in replacement CL, replacement
CL2 or replacement CL3 larger in flushing amount is selected and executed.
When ink cartridge change is made, change CL1 is executed for the nozzle lines
other than A and B. (Replacement CL is not applied.)
As the ink consumption, total suction is 1.35g and 2.12 x 106 of each color is
added. The differences between replacement CLs are differences in the flushing
amount of Lines A and B.
" Cartridge replacement CL1: Each color
Approx. 1.484g (0.212g per color)
" Cartridge replacement CL2: Each color

Manual cleaning
This product provides four 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 CL4 in order if the cumulative printing timer counter is less than 2H. Only
when the cumulative printing timer counter is more than 2H, execute only CL1.

2.2.7 Paper Cutter Mechanism
This printer consumes the ink of up to 1.27g/color depending on the combination
of the cumulative printing timer, cumulative cleaning count and cleaning timer.
! Flushing
This printer executes two different flushings for the following purposes.
" Periodic flushing
This is done to prevent ink viscosity in the Printhead nozzles from increasing
during continuous printing. A specific small amount of ink is discharged into
the Cap according to the Periodic flushing timer.
" Periodic large-amount flushing
This is done to prevent ink viscosity in the Printhead nozzles from increasing
during continuous printing. A large amount of ink is discharged into the Cap
according to the Periodic large-amount flushing timer.
The Paper cutter mechanism consists of such main parts as the Cutter motor, left and
right HP sensors (2 pcs. in all), Relay board, Paper eject roller shaft and Paper holddown flap in the Cutter unit.
! Operation during printing
When the Cutter blade starts cutting, the Paper hold-down flap rises and holds the
paper during cutting. The HP sensors for detection of the Cutter blade position are
installed on both ends of the cutter operation area, detect whether the Cutter blade
operates properly, and displays Cutter position error or Cutter jam error according
to the operating condition.

2.2.7.1 Cutter Initialization Sequence
When the Cutter is fitted, the cutter initialization sequence is executed if the printer has
confirmed that the Cutter has been fitted (the Power switch blinks about 5 seconds).
The cutter initialization sequence is an operation performed to securely put the Cutter
blade in a standby position detected by the right HP sensor if the Cutter blade is not
detected by the right HP sensor. In the initialization sequence, if the Cutter blade does
not reach the HP sensor (right or left) within 3 seconds in either rightward or leftward
Cutter motion, Cutter position error occurs. If the Cutter blade is in the right HP sensor
position when the Cutter is fitted, the initialization operation is not performed
specifically.
In Cutter operation, Cutter position error or Cutter jam error is detected.
Differences between these errors are as follows.
! Cutter jam error
If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is
returned to the HP sensor located in the motion starting position (right HP sensor).
At this time, Cutter jam error occurs if the Cutter blade can return to the HP sensor
position located in the motion starting position within 3 seconds.
! Cutter position error
If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is
returned to the HP sensor located in the motion starting position (right HP sensor).
At this time, Cutter position error occurs if the Cutter blade cannot return to the HP
sensor position located in the motion starting position within 3 seconds.
2.2.7.2 Cutter Self-cleaning
In the Cutter unit, there is a plate (plate where the paper print surface comes into
contact) above the Paper hold-down flap. This sequence indicates the operation
performed to hold down and remove the ink, which may stick to that plate, with the
leading edge of the fed roll paper.
Since the Cutter blade must be operated left-to-right to operate the Paper hold-down
flap, the Cutter blade generates operating noise during cutter self-CL when the roll
paper is fed.
2.2.7.3 Cutter Cleaning (Driver Side)
This sequence is executed on the driver side. By cutting the roll paper three times
(T.B.D.) at intervals of 6cm, the ink that may stick to the Cutter blade is removed to
clean the Cutter blade.
Paper cutting by the Cutter consists of the basic cutting sequences 1 and 2. The basic
sequence 1 means movement from the right HP sensor to the left HP sensor. At this
time, as soon as the Cutter blade starts moving from the right HP sensor, the timer
starts. If the left HP sensor does not detect the Cutter blade within 3 seconds, the cutter
initialization sequence is executed and then Cutter jam error or Cutter position error
occurs.
The basic cutting sequence 2 means movement from the left HP sensor to the right HP
sensor. At this time, if the Cutter blade cannot move from the left HP sensor to the right
HP sensor within 3 seconds, Cutter position error occurs.

2.2.8 Power-On Sequence
The following explains the operation to be performed when there is paper or no paper
and the Carriage is inside or outside the HP with the printer powered on.
! Without paper/Carriage inside HP (CR locked)
1.When power is switched on, the drive of the CR motor is transmitted to the
Carriage through the timing belt.
2.Using the transmitted drive, the Carriage starts operation in the following path to
seek for the home position.
• Home position → Right frame → CR lock lever → Right frame →
Home position
3. The drive from the PF motor is transmitted to the Paper eject roller shaft A and the
CR is unlocked.
4.In the path indicated in Sequence 1, after the Carriage has moved to the right frame
(second time), the drive of the ASF/Pump motor is transmitted to the LD roller
shaft through each gear of the DE unit to rotate the LD roller shaft, placing the
ASF unit in the home position.
• ASF/Pump motor → Planetary lever unit → Combination gear 12, 22.4 →
5.The unlocked Carriage moves to the left frame and then returns to the right frame.
The Carriage stops there for about 5 seconds, and during that period, the PF roller
shaft and Paper eject roller shafts A, B start rotating slowly.
6.The PF roller shaft and Paper eject roller shafts A, B stop rotating once, but restart
rotating suddenly. When the Carriage moves between the left and right frames
again, the ASF unit returns to the pre-power-on status (initial status), and the
Carriage returns to the home position and is fixed by the CR lock lever.
! Without paper/Carriage outside HP
1.When power is switched on, the drive of the CR motor is transmitted to the
Carriage through the timing belt.
2.Using the transmitted drive, the Carriage moves to the home position slowly.
3.When the Carriage reaches the home position, the PF roller shaft and Paper eject
roller shafts A, B start running suddenly by the drive from the PF motor but stop
soon, and the Carriage is fixed by the CR lock lever.
4.After that, the operation as in "Without paper/Carriage inside HP" is performed.
! With paper/Carriage inside HP (CR locked)
Operation is the same as in "Without paper/Carriage inside HP". When there is
paper, however, the operation perf ormed when the ASF unit detects the home
position will be explained here additionally. The following operat ion is the same
as in "Without paper/Carriage inside HP" or "Without paper/Carriage outside HP",
provided that there is no paper.
1.The Paper return lever installed on the LD roller unit goes down to feed the paper
but stops above the Paper separation pad.
2.After that, when the ASF unit returns to the pre-power-on status (initial status), the
Paper return lever moves back the paper that was stopping above the Paper
separation pad.
This is done to prevent double feed during paper feeding.
3.The Carriage is fixed by the CR lock lever.
! With paper/Carriage outside HP
In addition to the operation in "Without paper/Carriage outside HP", the motion of
the Paper return lever in "With paper/Carriage inside HP" is performed.

The following shows how the three circuit boards are connected.
The power supply circuit board of this product is the C387 PSB/PSE. The basic structure of
the circuit uses the RCC switching regulator method and +42VDC and +5DVC are
supplied to the printer mechanism and control boards.
The following indicates the applications of the voltages generated in this power supply

PF motor, ASF/Pump motor), head control/drive circuit, interfaces (1284, USB, 1394,
USB2.0), sensor circuits, combination circuits (RTC, reset, EEPROM) and electrical
double-layer capacitor.
There are the following two great differences between the control circuits of this
product and conventional model.
! Adoption of 3.3V/2.5V drive logic circuit components
The 3.3V/2.5V voltage is generated by the Regulator ICs (IC15, IC31) installed on
the C387MAIN board that reduces +5VDC generated by the C387PSB/PSE board,
and is used to drive multiple components. This is done to save power of the logic
circuit.
