Following lists “Notes” when using Parallel Interface.
“Return GND pin” in the table means twist pair return and is used for all control signals except for
Logic H,+5V, Chassis, GND and NC. In this twist pair return, returning side is connected to
GND (16,33, 19-30 pin) for twist pair return. Also, these cables are shielded wires and it is
effective to connect to each chassis GND in the PC and printer for electrostatic noise.
Conditions for Interface are based on TTL level. Rise and fall time should be within 0.2ms.
Refer to the figure 1-9 for transmission timing of each signals.
Do not perform data transmission ignoring /ACK or BUSY signal. (Perform the data transmission
after confirming that /ACK and BUSY signals are Low.)
It is possible to perform the printing test including interface circuit without using equipment from
outside when 8-bit data signal(20-27 pin) is set to appropriate word code and connect them
forcefully to /ACK and /STRB.

Prevention Hosts from Data Transfer time-out
Generally, hosts abandon data transfer to peripherals when a peripheral is in the busy state for dozens of
seconds continuously. To prevent hosts this kind of time-out, the printer receives data very slowly,
several bytes per minute, even if the printer is in busy state. This showdown is started when the rest of
the input buffer becomes several hundreds of bytes. Finally, the printer is in the busy state continuously
when the input buffer is full.

1.5 Error Status
When following status occur, the printer goes to the error status and stops taking data, setting the
/ERROR signal in the interface as “Low”, and Busy signal as “High”. At this time, the printer goes to non
printable status. Refer to section 1.4.2 for more details of LED Panel indicators during the various error
status.
1.5.1
Ink Out
When the printer runs out the most part of the ink of any one color, it warns ink-low and keeps printing.
When the printer runs out the whole ink of any one color, it stops printing and indicates ink-out error.
User is requested to install a new ink-cartridge in this state. An ink-cartridge once taken out should never
be used again. Re-installation of the cartridge not filled fully upsets the ink level detection and may
cause a serious problem in the print head as a result.
WARNING
Never use the ink cartridge once taken out from the printer.
Following explains the reason of the above warning.
After the cartridge is once taken out, airs come in from the ink supply hole located at the top of
cartridge and becomes bubbles, and they are absorbed into the head during printing performance.
Therefore, the head will be unable to discharge the ink properly. Also, inevitable entering of bubbles
when installing a new ink cartridge can be absorbed to ink itself since the ink itself in the cartridge is
deaerated during the production process. However, this absorbing ability can last only about one hour
after the cartridge is installed.
Even after the bubble absorbing ability described above stops, there is no worry about entering
bubbles as long as the ink cartridge is being installed to the printer. However, if the ink cartridge
which does not have absorbing ability any more is once removed from the printer, new coming
bubbles into the cartridge will never disappear naturally. These bubbles may cause not only printing
malfunction but also thickening ink. This thickened ink goes into the head and clogs ink path in the
head or nozzle and may cause serious head damage.
As standard specification for EPSON Stylus Color 600, ink consumption counter is reset when the ink
cartridge is removed. If an ink cartridge is removed and re-installed unnecessarily the value on the
ink consumption monitor which the user can check will be wrong and
printer may keep printing
even though the ink cartridge is installed empty. This may cause head damage.
1.5.2
Paper Out
When printer fails to load a sheet after power on operation including timer-cleaning is done and
Load/Eject button on the FF command or operation panel is pressed, it goes paper out error.
1.5.3
Paper Jam
When printer fails to eject a sheet even after feeding motion is completed or Load/Eject button on the FF
command or operation panel is pressed, it goes paper jam error.

according to the ink cartridge exchange operation.)
Ink cartridge exchange operation is done correctly. After the position of carriage is moved by
exchange operation, if the cleaning switch is pushed without installing ink cartridge or if the
carriage returns to the home-position automatically without doing any operation, it is considered
as
handling mistake. However, it returns to normal state by performing ink exchange operation again
and installing cartridge correctly.
If “No ink-cartridge error” appears even after the ink cartridge is installed, the printer must be
something wrong and around the sensor area in the carriage need to be repaired.
If sometimes printer can print normally but also sometimes “No ink-cartridge error” appears, the
printer must be something wrong. (Same reason as above)
1.5.5
Maintenance Request
When the total quantity of ink wasted through the cleanings and flushing reaches to the limit, printer
indicates this error and stops. The absorber in the printer enclosure is needed to be replaced with new
one by a service person. The ink quantity that is absorbed by the absorber (waste ink pad) is monitored
by the software counter as “total ink counter”. This counter is added by point system and absorber’s
maximum ability is set at the following reference value.
29500 X 0.012 ml = Approximately 301ml
1-point = 0.0102 ml (the value which is multiplied evaporating rate and 1-dot ink weight 0.02
ml)
29500 = Maximum point number (Maintenance error threshold)
However, considering dispersion of ink absorbing quantity and the number of using nozzles, ink total
value is calculated by the following formula.
301 X 1.1/63% = 526ml (but up to 532ml can be retained)
WARNING
When you perform self- test after completing repairs, it is possible to check the present value of total
ink counter and ink discharge conditions from all nozzles by performing status printing in the built-in
function. Therefore, make sure that the printer has enough value of total ink counter (if the number is
close to 29500 or not). If there is not enough value, the service man is required to judge if it is
necessary to clear EEPROM after replacing the absorber (waste ink pad) or not. Refer to section
1.3.1 if you need to perform EEPROM Clear.
1.5.6
Fatal Errors
When printer detects fatal errors such as carriage control error or CG access error, it goes to this error
mode. Refer to followings for each error.
Carriage control Error: Parallel adjustment malfunction, Home-position malfunction, Timing belt
tension malfunction, shortage of lubricant on the carriage guide shaft, etc.

Printer Mechanism
Unlike EPSON’s previous ink jet printer mechanisms, one of the major characteristics of EPSON Stylus
Color 600 is that the printer has no Engage/Disengage mechanism in order to change over pump
mechanism and paper feeding mechanism. Instead, however, this change-over control is done by the
distinction between turning direction of PF motor and position of present carriage unit. Also, another
major characteristic is that print head is changed to be one unit combined with black and CMY. Nozzle
configuration for black is 64 nozzles (the nozzle pitch of each column is 90dpi and between two
consecutive nozzles in number (e.g. #1 and #2) is 180dpi). On the other hand, CMY nozzle has 32
nozzles (90dpi) for each color. Following figure shows exterior of mechanism.

C206 PSB/PSE Board
The C206 PSB/PSE board is a switching regulator type power supply unit and constantly supplies stable
logic and power voltages to the printer mechanism and the main control board. Also, since this C206
PSB/PSE board has the power switch in the secondly side of the circuit, it is possible to keep supplying
electricity to the C200 MAIN control board for 30 seconds even after the power switch is turned off. Using
this time difference, even when mis-operation is done by the user such as turning off the power during
the middle of printing work, it prevents unexpected trouble with the printhead from occurring, by
transferring the printhead to the cap position before complete shut down. The C206 PSB Board is for
AC100 - 120V input voltage and the C206 PSE Board is for AC220 - 240V input voltage.

2.1 OVERVIEW
This section describes Printer Mechanism, electric circuit board (C206 PSB, C200 Main, C206PNL
board) of Stylus Color 600.
2.1.1
Printer Mechanism
Unlike previous EPSON Ink Jet printers, printer mechanism of Stylus Color 600 does not have exclusive
mechanism to change over paper feeding and Pumping operation. In stead, this control is done by the
turning direction of paper feed/pump motor and position of carriage at that time. Also, unlike previous print
heads, print head of this printer is became one unit combined with black and CMY head. Black head has
64 nozzles, 180 dpi(vertical direction) and CMY head has 32 nozzles, 90 dpi (vertical direction). Also, since
these print head is driven by frequency 14.4KHz, this printer can print double resolution(1440 dpi/100-dpi)
than Stylus Color. Following figure2-1 shows outline of printer mechanism.
Since the head drive frequency of Stylus Color was 7.2KHz, it could be only 720-dpi printing when it
driven by 100 cps carriage speed. It performs two-pass carriage operation when Stylus Color 600
performs the 1440 dpi printing towards the horizontal line.

Printing Mechanism
Basic principles of the print head which plays major role of printing mechanism is the same as previous
models; on demand type MACH head method, but there is some difference in the resolution. (Refer to
figure1-1) Also, unlike Stylus Color II, Stylus 820 and Stylus Color 200 automatic correction type, in order to
fix the dispersion of mufti layer piezo electric element which is used for driving each nozzles, it is necessary
to input the VH value written on the side of print head by using exclusive program when you replace print
head, control board, or the printer mechanism.(However, there are no resistor array for decide the VH
voltage on the main control board.) Following explains print head.
PZT
PZT is an abbreviation of Piezo Electric Element. Print signal from C200 board is sent through
the driver board on the print head unit and to the PZT. Then, the PZT pushes the top cavity
which has ink stored, and make the ink discharge from each nozzle located on the nozzle
plate.
Cavity Set
Ink which is absorbed from ink cartridge go through the filter and will be stored temporarily in
this tank, which is called “cavity” until PZT is driven.
Nozzle Plate
The board with nozzle holes on the printer head surface is called Nozzle Plate.
Filter
When the ink cartridge is installed, if any dirt or dust around the cartridge needles are
absorbed into the head inside, there is a great possibility of causing nozzle clog and
disturbance of ink flow and finally causing alignment failure and dot-missing. In order to
prevent this, filter is set at cartridge needle below and ink is once filtered here.

When the print signal is output from the C200 main board, IC(IR2C72C and IR2C73C:Nozzle
Selector) located on the print head unit latches the data once by 1-byte unit. Appropriate PZT latched
by nozzle selector is pushed in to the cavity by applying common voltage from the C200 main
board. By this operation, ink that is stored in the cavity pops out from nozzles.

Printing Method
This section explains printing method of actual printing such as printing text at various resolution
select/printing mode and graphics printing. In order to prevent white or color banding which are peculiar
problem of ink-jet, new Micro-Weave functions are added to the previous Micro-Weave function. The
number of nozzles and printing mode according to the selected resolution are used separately by a user.
The table below shows relation between selected resolution and printing mode.

Forward Overlap-Nozzle and backward Overlap -Nozzle are described in the [1.Full Overlap
Mirco-Weave] and [2.Part line Overlap Micro-Weave] below.
Following explains operation outlines of new Micro-Weave functions listed above.
[1. Full Overlap Micro-Weave]
In order to print one line at horizontal direction, this printing method is designed to complete a printing
pattern by two-pass carriage operation with two different types of dot. When this two different types of dot
pass one same line twice, it does not print the same dot twice.
The nozzles whose configuration completely match to the black and CMY nozzle are used.
(Usually Micro-Weave type)
Therefore, all nozzles in case of CMY nozzle and #1•`#63 nozzles in the B2 line in case of
black head are its objects. (B1 line is not used at Micro-Weave. Refer to figure1-1 for detail of
nozzle configuration.)
Out of these 4 color nozzle objects, the number of all nozzles which are going to be used are
divided equally into 2 groups.
Paper feeding will be done as many as each number of nozzles which are divided into two
groups and the same number of dots.(for example, if there are two 10-nozzle groups during
360-dpi printing at longitudinal direction, paper feeding of 10/360-inch becomes available.)
At this time, two groups perform Micro-Weave individually and particular lines are passed by
two different nozzles.
Note1) These nozzles which are divided into two groups must be set and divided in order to
be a pair of odd and even number.
2-4
Rev. A
Note2)
Chapter2 Operating Principles
Two groups which are divided according to each elements will be divided either even dot or
odd dot when particular lines(level direction line) are formed and eventually, these lines will be
completed at selected resolution. Following is a conceptual figure when full overlap microweave orms a particular line.

Note 3)
The way firmware decides which nozzle becomes even dot or odd dot is determined
as it is described below.
If the line which is about to be printed is even line:
First dot prints odd dot lines and 2nd dot prints even dot lines.
If the line which is about to be printed is odd line:
1st dot prints even dot lines and 2nd dot prints odd dot lines. Eventually, horizontal resolution
will be the same resolution as selected one.
[2.Part Line Overlap Micro-Weave]
This printing method is to perform Micro-Weave printing, overlapping a part of nozzles which are
used for printing. As a result, a part of raster which is overlapped consists of different browse with
different nozzles. The figure below shows 1-line Overlap at 5-dot sending as an example with
explanation on the next page.

EPSON Stylus Color 600
The difference between Full-Overlap Micro-Weave and Part line Overlap Micro-Weave are
following;
Full-Overlap Micro-Weave:
Printing is performed, judging if nozzles are even or odd dot by 2 different dots with all
different rasters.
Part line Overlap Micro-Weave:
After particular nozzles(only#1, and #6 in the figure2-7) are determined as overlap nozzles,
even or odd dot will be determined like Full-overlap Micro-Weave does.
(Forward Overlap Nozzle is determined as even and backward nozzle is odd.)
Also, nozzles other than particular nozzles can print at even and odd dot just by one
nozzle.
1) Overlap Nozzle
: Head drive frequency is driven half of the ordinal one like 2)
below.
2) Nozzle other than Overlap nozzle : Head drive frequency is twice as much as overlap nozzle.
Usually, the firmware changes over automatically these full overlap Micro-Weave, Part line Overlap
Micro-Weave, and ordinal Micro-weave according to the selection of resolution. Also, when these three
printing modes are performed by the Stylus Color 600, the printer performs top and bottom margin
process in order to control the overprinting volume as little as possible.

Carriage Mechanism
Carriage mechanism is to drive the carriage with print head mounted from left to right or vice versa.
The carriage drive motor in this printer is a 4-phase, 200-pole, stepping motor and is driven by
1-2phase, 2-2phase and W1-2phase drive method. This stepping motor allows the carriage to
move freely to the particular positions which is necessary for various operation, such as paper feeding,
ink absorbing, flashing, ink exchange and cleaning operations. The tables below shows carriage motor
specifications and motor controls at each mode.

The table below shows W1-2 phase drive sequence at each steps when the rotor of carriage motor
makes one rotation. In the Stylus Color 600, in addition to a function that printing is performed with W1-2
drive phase, high speed skip mode which is a function to skip over the blank from the end of the printing
data to the next data starting point with high seed can be also performed by 2-2 and 1-2 phase drive.
W1-2 phase requires 4 times as much steps as 2-2 phase drive, calculating 2-2 phase as standard.
By using this method, it becomes possible to supply constant stable torque to the motor. As a result, it
also became difficult to be influenced by vibration from the printer mechanism during printing.

This W1-2 phase drive (or 2W1-2 phase drive) is called Micro-step and is attached with so called 2/3•EVref
or 1/3•EVref factor, compared with drive current value (Vref100%) which is supplied at 2-2phase drive. This
Micro-Step allows the rotor to have delicate rotation. In the 2-2 phase drive method, it is usually
required to take 4-step sequence in order to rotate the rotor once. However, in case of W1-2 phase,
it is required to take 16-step sequence(in the table 2-4, sequence 0•`15) which is 4 times more than
2-2 phase method to do that. Also, in case of 2W1-2 phase drive which can be seen in the Stylus Color
etc., it takes 2-step to rotate the rotor once. The table below shows relation of rotation direction of rotor and
carriage proceeding direction.

Chapter2 Operating Principles
The figure below shows carriage mechanism. The print head as a core of the printing mechanism is stored
in the carriage unit. This print head keeps the tilt of print head in flexible and adjustable structure by
moving the adjustment lever up and down by the tilt adjustment mechanism. (Refer to chapter 4 for more
details) Also, parallelism adjustment lever is mounted on the left and right side of carriage guide shaft and it
adjusts parallelism degree between platen and shaft when this shaft is installed to the printer mechanism.
After this adjustment is completed and operate PG adjustment lever, it becomes possible to change the
space between platen surface and print head surface into 2 phases; either 1.1mm to 1.8mm. It is possible
to vary the space between platen surface and print head by rotating the axis of carriage guide shaft which
itself is decentralized, with the operation of PG lever. This is the mechanism that user can adjust the
appropriate PG value by himself according to the paper thickness or any other environmental conditions
such as paper curl.
Carriage lock mechanism is to prevent the carriage from being left at uncap position for a long time because
of vibration during the printer transport or mishandling by the users. If the carriage is left at uncap
position and uncap state of the print head for long time, an ink on the print head surface gradually becomes
viscosity. As a result, the nozzle will be unable to discharge an ink. To make matters worse, the
holes(crater) of nozzle may be completely clogged by the viscosity ink and it may not be able to return to
the normal condition just by cleaning operation. In order to prevent this, printer goes to carriage lock state
at the following conditions.
After Power OFF operation:
If the power is turned off on the way of printing or any other performance, carriage lock will be
performed in the end after completing initialize operation.
After power ON operation:
After power is turned on and automatic P-On Cleaning is performed, then carriage lock will be
performed. P-On Cleaning is an automatic head cleaning that is performed when the power is
turned on. The timer IC always calculates printer’s power OFF time by the power of lithium
battery mounted on the C200 main board. P-on cleaning function automatically selects the
cleaning level according to the time which the printer is not in used.
After Eject the paper:
After Load/Eject button is pressed and the paper is ejected, if the data is not input, the printer
performs carriage lock and goes to standby state. However, if the paper is loaded to the printer
inside by Load/Eject button, the printer does not perform the carriage lock operation.

It is a major premise that parallel adjustment is done correctly for the space between head and platen
(PG adjustment value above) which can be changed by platen gap adjustment.
Parallel adjustment should be done when the serviceman mounts the carriage guide shaft on the printer
mechanism during the production process or repair service. In the adjustment, the space between
parallel adjustment lever and gauge should be 1.04 mm.

Paper Feed Mechanism and Pump Mechanism
Mechanisms that send the paper in the hopper to inside the printer and perform constant paper
feed in order to perform printing on the sent paper are called paper feed mechanism as generic name.
In the Stylus Color 600, 4-phase, 200-pole hybrid type pulse motor is used in the PF motor as a motive
power of the paper mechanism and driving is done at 2-2 and 1-2 phase drive method. This motor is
not only used as a power source for paper feed mechanism but also used as power source of pump
mechanism which is necessary for print head cleaning. By using this pulse motor, it becomes possible
to use high speed driver or intermittent drive for the various paper feeds and pump operations such as
paper feed, slight paper feed, high and low speed absorption of pump operations. Following tables(Table
2-7 and 2-8) show PF motor specifications and control method at each mode.

Papers on the ASF (auto-sheet-feeder) supplied by the user are carried to the printer inside by paper
pick up sequence. Unlike the previous models, ASF of Stylus Color 600 has mufti feed prevention
mechanism. Following explains this function and figure below shows its mechanism.
[1. Multi feed prevention mechanism]
When the Load/Eject button is pressed, reversed rotation of PF motor is performed.
The return lever resets papers which are already in the out of stand by position in the stand by position
and make it possible to perform stable paper feeding by picking up the paper again.

When the load/Eject switch is pressed or printing order is input from the PC, PF motor rotates
counterclockwise and makes the CAM rotate towards direction of 1 in the figure above.
When the CAM covers the notch by the return lever, that position is considered as home
position, being monitored by ASF sensor.
When the CAM rotates toward 1 in the figure above, the return lever is pushed by the notch
of CAM and falls towards 2. At this time, the return lever moves to direction 3 by this
motion, and push down the pad which is waiting in the below part. At this time, friction of
pinch roller and pad will be canceled.
The papers which are out of stand by position by the previous paper feed motion are
returned to the paper stand by position by flip over strength of return lever. After this,
PF motor rotates clockwise and the printer goes to pick up sequence.

Chapter2 Operating Principles
In the paper pick up mechanism of Stylus Color 600, same mechanism as Stlylus Color IIs/820
are applied. This mechanism changes adjoined lines of gear by colliding trigger lever with carriage
unit and convey the motive power on the platen to the ASF side(paper roller). The figure below
shows mechanism with explanation.
[2. Paper pick up mechanism]
When the Load/Eject switch is pressed or printing order is input, the carriage unit moves until
the left edge and collides with paper pick up trigger lever. When the carriage collides with this trigger
level, a planetary gear located on the same axis is also pushed at the same time and conveys
the motive power on the platen to the adjoined gear line side for ASF drive.

After papers in the ASF receive controls from pick up and multi feed prevention mechanism, they are
sent to the printer inside. The papers picked up by paper roller in the ASF goes to between platen
and roller support. Also, the eject roller pushes out the paper completely until the end and the roller support
drops the paper in the eject tray. The eject roller is driven with an eject paper notched roller as pair where is
located on the paper eject roller. Paper eject notched roller solves the deflection of paper that is in the
between platen eject notched roller and paper eject roller and always keep a certain space
between print head and paper surface. The figure below shows paper feed mechanism.

Ink system mechanism consists of 1)cap mechanism, 2)pump mechanism, 3)carriage lock
mechanism, 4)waste ink absorber and 5)ink sequence. Out of these mechanism, from 1) to 4)
are physical mechanism and parts which are mounted on the printer mechanism and 5) ink
sequence is performed automatically by firmware. Also, unlike previous models, since
Stylus Color 600 has no engage/disengage mechanism to change over pump mechanism and
paper feed mechanism, it is one of the major characteristics that pump and platen are always
at work whenever the PF motor is driven. The figure below shows head positions when the ink

Pump, Carriage Lock, Head Cleaner Mechanism
In the Stylus Color 600, there is no switch or mechanism to change over the pump/paper feed mechanism.
Therefore, whenever the paper feed/pump motor rotate, pump drive roller in the pump unit inside rotates.
However, ink absorption/non ink absorption are separated by the roller rotational direction. Also, even if the
pump driver rotates toward ink absorption and the carriage position is in the false absorption position, only
driving in the pump mechanism is performed and actual ink attraction is not done. The figure below shows
process of conveying motive power to the pump drive roller.

The process of conveying the motive power to the paper eject roller by rotating the pinion of PF motor
is descried in figure 2-14. This motive power is conveyed to the Gear C through Gear B.
In the figure above, although the lever in order to drive Gear C, carriage lock, head cleaner mechanism
is shown separately, it is constructed as one unit. Since the engagement of these two parts depends on the
tension of the compression spring, if the lever is burdened, only Gear C and pump roller rotate and no
more motive power is conveyed to the lever part.

Figure 2-15. Pump Roller Rotation and it’s Operation
In the ink absorptive operation such as cleaning, flushing initial ink charge except for printing operation,
ink in the ink cartridge drains to the waste ink absorber(pad) through the cap by the pump unit drive.
In case of printing and flashing drive, ink is popped out by the PZT in the print head, but in case of
absorptive operation such as cleaning and initial ink charge, ink absorption is performed
only by the pump drive without PZT drive after the head surface is adhered to the cap.
The next page explains cap mechanism and relation between printer operation and cap.

Cap Mechanism
In the cap mechanism, in order to prevent ink from being thickened on the head surface, it is controlled
that the head surface stays adherent to the rubber frame of the cap surface when the power is off.
The absorber is spread in the cap and can hold a certain amount of ink which is absorbed from the
head without draining it to the waste ink pad. Also, in the bottom of absorber, there are two valves in order
to control adhesion of head and cap surface, and one exit to drain ink to the waste ink pad.

If the carriage is out of HP(in this case, in the printable area or paper feed position), the valves on the
cap mechanism stays in the position A in the figure above and are always closed. In this condition,
the carriage collides with flag, actual ink absorption and slight ink absorption are performed.
Also, by moving the carriage to further right side and colliding the flag for opening the valves with
the frame, negative pressure is released in the state that head surface and cap are adhered. This
makes it possible for ink on the nozzle plate surface to be ready for leaving from the cap in the stable
condition.

C206 PSB/PSE Power Board
C206 PSB/PSE board is a power supply board with a RCC switching regulator, which generates +42VDC for
drive part and +5VDC for logic part to drive the printer. One of the major characteristic of this board is that
the same secondary switch is used as Stylus Color series printer. By using this switch, the following
difference can be seen as superficial phenomena compared with products applied with primary switch
method, such as Stylus Color IIs, II and Stylus 800/1000 series printer. The table 2-12 below shows
application of voltages generated by C206 PSB/PSE board.
1) Even if the switch is turned off during the middle of printer operation, since the driving
power is turned off after the carriage goes back to the carriage lock position,
the possibility of clogging ink nozzle will be decreased.
2) If the switch is turned off when the papers in the printer are still being carried except for
the papers in the hopper, the same operation mentioned above is performed and the
driving power is turned off after the paper is completely ejected.

Figure 2-18 shows block diagram of C206 PSB/PSE board. The process from the input of AC100V to the
output of DC42V and 5V is explained below.
1) Regardless of the state of power switch(On or OFF), the voltage is always applied in the primary
side of the power supply board from the moment or at the state that AC-plug is plugged in.
At this time, F1 plays a role of preventing AC100V from coming into the F1.
L1 and R1-R2 also prevent high harmonic wave noise generated in the RC circuit filter which consist
of C1•`C4 and R1•`R2 from going out, and eliminate the noise from outside here.
2) The AC is full-wave rectified by diode bridge DB1, and converted to
electrolytic capacitor C11.
2 x AC in voltage by smoothing
3) The pressured up direct current makes Q1 On through the starting resistor R31 and starts the primary
side of the circuit.
4) When the primary side is On state, the energy(current) led by the electromagnetic induction through
the trans (T1) does not flow to the secondary side since the diode(D51) on the secondary side
is installed in the opposite direction.
5) When the energy which is charged in the trans is reaching the saturated state, the voltage which
makes the Q1 On becomes weak gradually. At the point that this voltage drops at the
certain voltage, C13 absorbs the current in the opposite direction and Q1 is quickly shut off by
the resulting sharp drop.
6) When the primary side is turned off, the energy charged in the T1 is opened according to the
diode(D51) direction which is installed on the secondary side. Basically, 42 V DC is output
by these circuit operations and the number of T1 spiral coil .
7) +5VDC is generated by pressured down this +42 V DC as power supply. IC51 pressures down the
+42 V DC and generates precise +5V DC by chopping off the output, forming the standard santooth
waveform by the outer RC integration circuit.

The C206 PSB/PSE board has various control circuits to stop output if malfunction on the power supply
board, on the main board or on the duty of printer mechanism happen. Following explains each control and
protection circuits.
1) +42V Line Constant Voltage Control Circuit:
The output level of the +42V line is monitored by a detection circuit consisting of seven Zener diodes.
This circuit prevents voltage from dropping for constant output voltage.
2)+5V Line Over voltage Protection Circuit:
This protection circuit is in the same line as +42V overvoltage protection circuit is located. The output
voltage level of the +5V line is monitored by a Zener diode. This circuit shuts down the circuit operation
forcefully when the voltage level exceeds +9V.
3) +42VDC Line Over voltage Circuit
This ciruit is in the same line as +5V line over voltage protection circuit is located. The output level is
monitored by two Zener diodes. If the voltage level exceeds +48VDC, this circuit stops circuit
operation forcefully.
4) +5V Line Constant Voltage/Constant Current Control Circuit:
The output current is monitored by a +5VDC generation switching control IC(IC51), which also
monitors the output voltage. This information is input to the internal comparator and stabilizes+5V
line. Also, operation of the secondary side switch is explained below.
1)
When the power is turned on, Q1 repeats ON/OFF automatically along with the increase and
decrease of energy on the trans coil at the primary side. While the power is being on, PSC
signal is input to the power supply board from the C200 main board.
2)
This signal turns Q84 on and it becomes possible to discharge energy between 8-9 of T1.
At this time, even if the power is turned off, the electrolytic capacitor keeps Q84 on for a while.
By this electrolytic capacitor, output is hold at least 30 seconds even after the power is turned off.
This time helps the printer to complete the P-Off operation.

[CPU]
The C200 main board is controlled by a 16-bit CPU(TMP95C061AF) running at 25MHz. Gate array
manages most of controls and monitors. Likewise Stylus Color, the D-RAM is applied for RAM
which is used as work area for receiving data and developing the data and CPU manages its control
such as CE, RAS/CAS controls.
[Gate Array]
E05B43 controls following functions.
Rev. A
Motor control :
Each motor performs data transmission(W1-2 phase) that motives
Micro-Step.
Head voltage control: In the ink jet printers, drive voltage wave form(trapezoidal wave form)
in order to drive PZT is formed in the various shapes according to the
types of the printers.
Therefore, it is necessary to form appropriate drive form for each head.
Head voltage control forms necessary waveform for each control
signals and outputs them.
EEPROM control:
The correction value to eliminate the error of each printers at the
production process is installed in the fixed address of IC.
When the power is turned off, the contents set by users is written
instantly, and is red to the RAM when the power is turned on.
Sensor Data:
The sensor detects information at the various conditions, which is
necessary for the printer operation. The gate array recognizes signals
and changes over to the next control.

EPSON Stylus Color 600
Timer Data:
The timer IC that uses lithium battery as power source monitors how
long the power is off. When the power is turned on, it is changed to
appropriate cleaning level according to the time that the power is off.
Serial Data:
The gate array receives serial data through the transceiver IC.
Parallel I/F control:
With the use of IEEE1284 Nibble mode, it became possible not only to
receive the data from the host but also to return various information
which the printer possesses to the host.
[Common Driver IC]
The trapezoidal wave form circuit for head drive is became to HIC from the previous discreate structure.
Because of this, it is not necessary to adjust the adjustable VR on the board during production process.
Various electric charge/discharge control signals are all processed in the HIC.
[CR/PF Motor Drive Circuit]
Constant current drive is performed by the HIC. Out of this, only CR Motor is controlled for Micro-Step
control and HIC becomes possible to flow the appropriate current value at each steps. (PF Motor has only
1-2, 2-2phase drive method). Also, bipolar drive is performed on the 4 cables individually. Following
pages explain each major control circuit.

Reset Circuits
The reset circuit prevents the CPU from running away, which is caused by the unstable voltage in the
logic line during the power ON/OFF. Also, this circuit monitors level of power voltage at the overloading
or malfunction on the circuit and manages the printer to operate normally, keeping the damage to the
printer minimum during the abnormal situations. On the C200 main board, 2 ICs are mounted ; IC for
monitoring the voltage level (logic line) and IC for monitoring the voltage level (power line) and both
are monitored by the gate array and CPU.

The actual operation of the circuit is to keep outputting Low signal until +5V line goes up to +4.2V
when the power is on, and to cancel the reset signal with output of High signal when the voltage goes up
more than 4.2V.

This IC also performs as monitor on the power line same as the reset IC for logic described above.
High/Low is judged at the 33.2V.
[Relation between IC8 and IC9]
Reset signal which is low and output by IC9 is input to the CPU and gate array and system reset operation
is performed. Also, this signal is detected on the IC9(IC for reset monitor, power line) and outputs the

An ASF sensor detects the position of return lever when the power is
turned on, and causes the paper to be picked up by the pick up roller
from the normal initial condition. (Refer to section 2.1.1.3 for detail.)
PE Sensor:
(Photo)
A PE sensor determines if there is paper in the printer. Based on the
signal form this sensor, a particular paper edge treatment such as
Micro-weave printing is performed.
HP Sensor:
(Photo)
A HP sensor detects the carriage home position.
It is used for managing printing position and cleaning, etc.
Thermistor Sensor:
A thermistor sensor keeps stable printing quality, changing PZT drive
voltage(VH) slightly according to changes of environmental
temperature.
Cartridge Sensors:
Cartridge sensors are built into the Bk, CMY cartridge on the carriage
unit respectively to determine if the cartridge is installed or not when it
is exchanged or the power is turned on. In case of Stylus Color 600,
the counter is reset at every time the cartridge is removed.
The figure below shows sensor circuit. Out of the data such as EPW with IEEE 1284 Nibble mode
to be returned to the host, the data to indicate ink consumption is calculated and managed by the

The followings explain about operation of this circuit.
When the printer is on, power is supplied to the Timer IC by applying +5V quickly through
the D4.
This power is also used for the power to oscillate the outer CR3. The oscillation wave form is
input to XIN terminal.
Since the oscillation wave form of CR1 is analog waveform, it is processed into the
pulse form in the Timer IC.
When the printer is turned on, the Timer IC outputs power off time as serial data to the gate
array.
Once the printer is turned off, 3VDC of BAT1(lithium battery) is supplied as power source for
the Timer IC through D1.
Since +5V at the power on is higher than +3V of the lithium battery, the power is not being
consumed from the lithium battery.
2.2.2.5
DRAM Control
In the Dynamic RAM control, output and formation of CAS and RAS control signals become necessary
in addition to the output of CS signal. The CPU TMP95C061AF not only controls that but also perform
the output of CS signal of P-ROM. Refresh timing is performed in the CAS Before RAS.

Print Head Control Circuit
The print head control circuit of Stylus Color 600 has following characteristics.
Common waveform circuit became one HIC.
Micro-vibration mode is added.(when the CR motor is accelerating)
High speed drive 14.4KHz (trapezoidal wave form
Enhanced Nozzle configuration (resolution in the vertical direction)90dpi
(However, black nozzle is 2 lines structure)
Also, Stylus Color 600 has Micro-dot control as dot shooting control. There are total three dot shooting
controls on this printer.
• Normal Dot mode(Single Firing)
• Normal Dot mode(Dual Firing)
• Micro Dot mode
• Micro-Vibration(Not printed)
The control circuit is considered as two divided parts; 1) trapezoidal wave form generation circuit
(common drive circuit) to drive PZT in the head, and 2) Nozzle-selector drive circuit to determine
which nozzle should be used. The Nozzle-Selector is attached to the head unit just like the previous
models. The common drive circuit is became as HIC and mounted on the C200 main board.

[Nozzle Selector Drive Circuit]
In order to motivate the print head to carry out printing, it is necessary to transmit the print data to the
appropriate nozzles, which becomes direct signals to drive PZT. This data transmission is performed
by the serial transport method, however the data output for each black and CMY head is transmitted by the
parallel method. The figure below shows data transmission circuit.

CLK(Clock) pulse considered as source of serial communication is commonly used for both black and
CMY. The serial data transmits data as 64-Clock unit, synchronizing with this pulse. After the data
transmission of 64-Clock is completed, LAT(Latch) signal is activated and is hold temporarily in the
IR2C72C(U101) At this time, since the number of nozzle for Color head is fewer(21-nozzles) and different
from the ones for black head, 0 is transmitted forcefully for the data for 43 nozzle (64-21=43).

Chapter2 Operating Principles
After the data transmission by the nozzle selector(IR2C72C, IR2C73C) is completed and a certain time
passes, trapezoidal wave form generated by the common drive circuit once sends electric current to the
PZT for the proper nozzles which are determined in the nozzle selector circuit. This motivates PZT and
ejects the ink in the cavity. The figure below shows normal dot data transmission timing in order to from

PF(Pump) Motor Drive Circuit
IC15(UDN2917) is used for driving PF(Pump) motor. In the IC, Bi-pola drive PWM current control type is
performed, making it possible to provide stable current to each phase of motor. Also, it makes possible to
change over the reference voltage as drive current settings by making 3 combinations(100%,66% and
33%), using 4 current setting ports(input). (Refer to 2.1.1.3 for motor and details about sequence) However,
firmware does not drive Micro-step in the Stylus Color 600. The figure below shows the block diagram of
Unlike using Uni-Pola drive, there is no cable for GND in the motor since Bi-Pola drive is performed in the
PF motor.(Refer to section 2.1.1.2 since carriage motor interior connection diagram has the same
connection as the PF motor’s phase connection. This helps to understand the reason why the direction of
current is controlled freely in each phase by the combinations of high/low control signals.

The current control is performed by output port(46•`49 pin) of E05B43(IC2), its outer resistance circuit and
driver IC15(UDN2917). First, firmware possesses 16 ways of current values as current table out of
combinations made by 5 resistance which are connected to the output ports(46•`49 pin) in the gate array.
On the other hand, signals which are output by combination of these resistance’s on/off are input in the 25
and 44 pins. HIC is driven at the same standard voltage for each A and B phase.
Actual on/off control to send electricity through the motor is performed by the process that SEN1 and
SEN2 terminals (2 and 13 pin) detect the input signal from the gate array which is monitored by the
interior comparator, confirm the current that actually flew the phase as current value again and
perform the feed back to the on/off. The figure below shows relation between input signal to the

4.2 Adjustments
This section describes the detail procedure of each adjustment.
4.2.1
Paper Gap Adjustment
The paper gap is a distance between nozzle surface of the printhead unit and a paper surface and is
adjusted to specified gap at the assembly. Therefore, if the carriage assembly is removed from the printer
mechanism for any reason, this adjustment should be made to fix the gap.
CAUTION
Do not scratch the surface of “PAPER GUIDE, FRONT;B” and “ROLLER, ASSEMBLY, PF”.
Be careful not to damage or make dirty the nozzle surface of the printhead unit.
[Paper gap - Right-hand side Adjustment]
1. Attach both “BUSH, PARALLEL ADJUST” (L/R) to the side frame and align the position mark on
top edge of it to a notch on the edge of the side frame.
2. Set “LEVER, PG” to front side (Position “0”).
3. Move the carriage assembly to the middle, and put the thickness gauge at the position specified in
he figure.
4. Move the carriage assembly over the thickness gauge.
WORK POINT
The thickness gauge must be placed on a flat surface of the ribs of “PAPER GUIDE, FRONT;B”.
During adjustment, always pull the timing belt to move the carriage assembly.
5. Shift the position of “BUSH, PARALLEL ADJUST, RIGHT” to backward (Gap: Narrower) until when
the thickness gauge starts sliding together with the carriage assembly when you move it to right
and left for about 20mm.
6. At the point of above step, shift the position of “BUSH, PARALLEL ADJUST, RIGHT” for one notch
to forward (Gap: Wider).
7. Then, confirm that the thickness gauge do not slide when you move the carriage assembly, with
either “LEVER, PG” is at position “0” or “+”.
[Paper gap - Left-hand side Adjustment]
8. Repeat the above step 2 to 7 with “BUSH, PARALLEL ADJUST, LEFT”.
[Gap Confirmation]
9. Repeat the step 3 to 4 again.
10. Confirm that the thickness gauge do not slide when you move the carriage assembly to right and
left for above 20mm.
11. Shift the position of “BUSH, PARALLEL ADJUST, RIGHT” for one notch to backward (Gap:
Narrower) and confirm that the thickness gauge is sliding by moving the carriage assembly. If not,
return to step 1 and repeat adjustment again.
12. If the gap is correct, shift “BUSH, PARALLEL ADJUST, RIGHT” for one notch to forward (Gap:
Wider).
[Fixing “BUSH, PARALLEL ADJUST”]
13. Fix both bushes with 2 screws (1 each : No.1).
When the paper gap adjustment complete, confirm that the overlap of printhead nose and “CLEANER,
HEAD”.
1. Move the carriage assembly next to “CLEANER, HEAD”.

Adjustment using Adjustment Program
Since the characteristic of printer mechanism and its components are varying, every printer mechanism are
checked and it’s own characteristic information is stored in EEPROM of the main control board as a
compensation parameter for the mechanism control. Therefore, if the combination of printer mechanism
and the main control board is changed, the printer should be adjusted using the adjustment program in order
to maintain optimum performance of the printer.

the check pattern to see the level of head angular.
1. Before performing this adjustment, be sure to perform “VH Setting” (Refer to section 4.2.2.3)
2. At the main menu [SCREEN-4], input “3” to select “Angular Adjust Print” and press ENTER key.
3. Check to see if the lines printed in MAGENTA color is positioned in the middle of two BLACK
lines with the check pattern printed by the program. If the position of MAGENTA lines are
incorrect, input “K” at the main menu and the carriage assembly moves to the middle of the printer.
Then, loosen a screw (No.3) fixing “FASTNER, HEAD” and shift the position of angular adjust
level located at the right bottom of the carriage assembly to either forward (move MAGENTA
line to down) or backward (move MAGENTA line to up).
4. After adjusting the position of angular adjust lever, input “3” to print the check pattern and
verify the angular level. If the level is still not correct, repeat the step 3.
5. If the level is correct, input “K” again and tighten a screw to fix “FASTNER, HEAD”. Then, at
the menu [SCREEN-6], input “Y” and press ENTER key to complete the adjustment.

Chapter 4 Adjustment
4.2.2.5
Bi-D Alignment Adjustment
This adjustment defines the carriage drive control parameters to compensate the variation in mechanism
components characteristic so that the print position become even in bi-directional printing. This adjustment
is required when one of the following service is made:
Replacing the printer mechanism
Replacing the main board (C200 MAIN)
Replacing the CR Motor assembly
Replacing the carriage assembly and related components
The values defined with this adjustment are stored in EEPROM on the main board.
1. If the printer mechanism is replaced, the ink charge operation and the VH Setting operation should
be performed prior to this adjustment. (Refer to section 4.2.2.2 and 4.2.2.3)
2. Connect the PC to the printer and turn on the printer.
3. Go to the main menu [SCREEN-4].
4. Input “4” to select “Bi-d Adjust” and press ENTER key.
5. The program prints the check pattern (one with the compensation value=“0” and another two patterns
each printed with the value “-2” and “+2”). Select the number of the pattern with which the printed lines
are most properly aligned, and input the number and press ENTER key at the menu [SCREEN-7]. Then,
the program print the sample pattern with the compensation value you have selected.
If all patterns printed by the program are completely mis-aligned, confirm the inclination of misalignment
with the pattern printed with the value “0” by checking the relative position of the EVEN line to the ODD
line:
If EVEN line is shifted to RIGHT =
If EVEN line is shifted to LEFT =

Then, once input “Y” and press ENTER key to return to the main menu, and input “E” to select “Go to
SETTING MENU” and press ENTER key. At the setting menu screen [SCREEN-3], input “6” to select “BID Center” and input the approximation number that corresponding to the inclination of misalignment you
have confirmed previously. After changing the reference value for the Bi-D alignment check printing,
input “1” to select “(Production)” and back to the main menu and continue for the Bi-D alignment
adjustment.
6. If the alignment is correct, input the pattern number at the menu [SCREEN-7] and after completing
the sample pattern printing, input “Y” and press ENTER key to define the compensation value.

Chapter 6 Maintenance
6.1 OVERVIEW
This section describes the points and the procedures for maintaining the printer in its optimum condition.
6.1.1
Cleaning
This printer has no mechanical components requiring regular cleaning. Therefore, the points described
below are suggested to be checked for any dirt and make an appropriate cleaning if necessary.
CAUTION
6.1.2
Never use the chemical solvents, such as thinner, to clean the printer. These chemicals can
damage the components of the printer.
Be careful not to damage the components when you attempt to clean the inside of the printer.
Do not scratch surface of “ROLLER, ASSEMBLY, PF”.
(Use soft brush to wipe off any dusts, or use soft cloth moistened with alcohol)
Housing:
Use clean soft cloth moistened with water and wipe off any dirt. If the housing
stained with an ink, use a cloth moistened with a neutral detergent to wipe it
off.
Inside the printer: Use a vacuum cleaner to remove any paper dust.
Service Maintenance
If the print irregularity (missing dot, white line, etc.) has occur or the printer indicates “MAINTENANCE
ERROR”, perform the following operation to clear the error.
Head Cleaning
1. The printer has a built-in head cleaning function and is executable from the control panel.
2. Confirm that the printer is in stand-by state (the POWER indicator is not blinking), and hold
down the cleaning button on the control panel for more than 3sec.
3. The printer perform the built-in cleaning sequence. (during cleaning operation, the POWER
indicator is blinking)
Maintenance Error Clear
Since the printer consumes the ink, not only for printing but also for another operation like cleaning, certain
amount of ink are wasted. Therefore, the printer counts the amount of waste ink and they are collected at
the waste ink pad, and once the amount of waste ink reaches the predefined limit, the printer indicates
“MAINTENANCE ERROR” and the waste ink pad should be replaced as follows:
1. Replace the waste ink pad to new one.
2. After re-assemble the printer, turn the printer on while hold down the following buttons on
the control panel:
•E”LOAD/EJECT” button
•E”CLEANING” button
3. Press “LOAD/EJECT” button again while “PAPER END” indicator is blinking. This clears the
maintenance error condition and the waste ink counter value stored in EEPROM of the main
board.
