1.3 Interface
This printer provides both parallel and serial interface as standard.
1.3.1 Parallel Interface (Forward Channel)
[Transmission mode]
[Synchronization]
[Handshaking]
[Signal level]
[Adaptable connector]
BUSY signal is set high before setting either/ERROR low or PE high and held high until all these signals
return to their inactive state.
BUSY signal is at high level in the following cases.
During data entry (see Data transmission timing)
When input data buffer is full
During -INIT signal is at low level or during hardware initialization
During printer error (See /ERROR signal)
When the parallel interface is not selected.
ERROR signal is at low level when the printer is in one of the following states.
Printer hardware error (fatal error)
Paper-out error
Paper-jam error
Ink-out error

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.

1.3.2.1 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.

1.5.4 No Ink-Cartridge Error
Following reasons can be the causes when printer goes this error mode.
Chapter 1 Product Description
according to the ink cartridge exchange operation.)
When the printer is turned on for the first time.
(This is a normal error state and it returns to the normal state after installing an ink cartridge
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
However, considering dispersion of ink absorbing quantity and the number of using nozzles, ink total
value is calculated by the following formula.
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)
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.
CG Access Error: Short circuit, etc.

1.7.1 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.

1.7.3 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 m echanism of St ylus Color 600 does not have exclusive
mechanism to change over paper f eeding and Pumping operation. In stead, this cont r ol is done by the
turning di r ec tion of paper feed/pump motor and posi tion of c ar r iage at that time. Also, unlike previous print
heads, print head of this pri nter is became one unit com bined with black and CM Y head. Black head has
64 nozzles, 180 dpi( vert ical di r ec tion) and CMY head has 32 nozzles, 90 dpi (verti c al direct ion). Al so, si nc e
these print head i s driven by frequency 14. 4K Hz , this printer can print double resoluti on( 1440 dpi/100-dpi)
than Styl us Col or. Following f igure2-1 shows outline of printer mechanism .
Since the head driv e frequency of Stylus Color was 7.2KHz, it c ould be only 720-dpi printing when it
driven by 100 cps carriage speed. It perf or ms two-pass carriage operati on when Sty lus Color 600
performs the 1440 dpi pri nting towards the horiz ontal line.

2.1.1.1 Printing Mechanism
Basic principles of the print head which plays major r ole 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 autom atic correc tion type, in order to
fix the dispersion of mufti layer piezo electri c element whic h is used for drivi ng eac h noz z les, it is necessary
to input t he V H val ue wri tten on the side of print head by usi ng exclusive program when you replace print
head, control boar d, or the printer mechanism.(However, there are no resistor array for deci de the VH
voltage on the m ain control boar d.) Following explains print head.
PZT
Cavity Set
Nozzle Pl ate
Filter
PZT is an abbreviation of P iezo Electric Element. P r int signal from C200 boar d is sent through
the driver board on the pr int head unit and to the PZT. Then, the PZT pushes the top cavity
which has ink stored, and make the ink discharge from each nozzl e located on the nozz le
plate.
Ink which is absorbed f r om ink car tridge go through the fi lter and will be stored temporarily in
this tank, whic h is called “c avi ty” until PZT is driven.
The board with nozzle holes on the printer head surface is called Nozzle Plate.
When the ink cart r idge is instal led, if any dirt or dust around the cart r idge needles are
absorbed into the head i nsi de, there is a great possibility of causing nozzle clog and
disturbance of ink flow and fi nally causing alignm ent fai lure and dot-missing. In order to
prevent this, filter is set at cart r idge needle below and ink is once fi ltered here.

by nozzle selector is pushed in to the c avi ty by applying common voltage f r om the C200 m ain
board. By this operation, ink that i s stored in the cavity pops out from noz z les.

Following explai ns operat ion outlines of new Micro-Weave functions listed above.
[1. Full Overlap Micro-Weave]
In order to print one li ne at horizontal direct ion, thi s printing method is designed to complete a pr inting
pattern by two-pass carriage oper ation with two di fferent types of dot. When t his two diff er ent types of dot
pass one same line twice, it does not print the same dot t wic e.
FOL means Full Overl ap M icro-Weave.
POL means Part line Overl ap M icro- Weave
Forward Overlap-Nozzle and backward Overlap -Nozz le are described i n the [1.Full Overlap
Mirco-Weave] and [2.Par t line O verlap Micro-Weave] below.
The nozzles whose confi gur ation com pletely match to the black and CMY noz z le are used.
(Usually Micro-W eave ty pe)
Therefor e, all nozz les in case of CMY noz z le and #1•`#63 nozzles in t he B 2 line in c ase of
black head are i ts objects. (B1 line is not used at Micro-Weave. Refer t o figure1-1 for detail of
nozzle configuration.)
Out of these 4 color nozzl e objects, the number of all nozzles which are going to be used are
dividedequally into 2 groups.
Paper feeding will be done as many as each number of nozzles which are div ided into t wo
groups and the same number of dots.(for example, if t her e ar e two 10-nozzle groups during
360-dpi printing at l ongitudinal direction, paper feeding of 10/360-inch becomes available. )
At this time, two groups perform M icro-Weave individually and particular lines are passed by
two diff er ent nozzles.

Two groups which are divided acc or ding to each elements will be divided either even dot or
odd dot when particul ar lines(level directi on line) are formed and eventually, these lines will be
completed at selected resol ution. Following is a conceptual f igure when full ov er lap mi c r o-
weave orm s a part icular line.

Note 3) The way firm ware decides which nozzle becomes even dot or odd dot is determ ined
as it is described below.
If t he line which i s about to be printed is even l ine:
First dot pr ints odd dot lines and 2nd dot prints even dot lines.
If t he line which i s about to be printed is odd line:
1st dot prints even dot l ines and 2nd dot prints odd dot lines. Eventual ly, horizontal resolution
will be the same resolution as selected one.
[2.Part Line Overlap Micro-Weave]
This print ing method is to perfor m Micr o- Weave printing, overlappi ng a par t of nozzles which are
used for printing. As a result , a part of r aster whic h is overlapped consists of differ ent browse with
different nozzl es. The fi gur e below shows 1-line Over lap at 5-dot sending as an example wi th

1) Overlap Nozzle : Head driv e frequency is driven half of the ordinal one like 2)
below.
2) Nozzle other than Overlap nozzle : Head dr iv e frequency is twice as much as overlap nozzle.
Usually, the fir mware changes over automatically these full over lap Micro- Weave, Part line Overl ap
Micro-Weave, and ordinal Micro-weave accordi ng to the selection of resolution. Also, when these three
printi ng modes are perfor med by the St y lus Color 600, the pr inter performs top and bot tom m ar gin
process in order to contr ol the overprint ing v olume as little as possible.
The difference between Ful l-Overlap Micro-W eave and Part line O verlap Micro-Weave are
following;
Full-Overlap Mi cro-Weave:
Printing is perfor med, judging if nozzles are even or odd dot by 2 differ ent dots with all
different rasters.
Part line Overlap M icro-Weave:
After par ticular noz z les(only#1, and #6 in the figure2-7) are deter mined as overlap nozzles,
even or odd dot will be determined like Full-overlap Micro-Weave does.
(Forward Overlap Nozzle is determined as ev en and bac k ward nozzle is odd.)
Also, nozzl es other than particular nozzles can print at even and odd dot j ust by one
nozzle.

2.1.1.2 Carriage Mechanism
Carriage m ec hanism is to driv e the carriage wit h pr int head mounted from left to ri ght or v ice versa.
The carriage dr iv e motor i n this printer is a 4-phase, 200-pole, stepping motor and is driven by
1-2phase, 2-2phase and W1- 2phase drive method. T his stepping mot or allows the carriage to
move freely to the particular posi tions which is necessary for various operation, such as paper feeding,
ink absorbing, flashing, ink ex c hange and c leaning operations. The tabl es bel ow shows carriage motor
specifications and m otor control s at eac h mode.

The table below shows W1- 2 phase drive sequence at eac h steps when the rotor of carriage motor
makes one rotation. In the S tylus Color 600, in addition to a func tion that pr inting is performed with W1-2
drive phase, high speed skip m ode whic h is a function to skip over the blank from the end of the print ing
data to the next data starting point wit h high seed can be also perfor med by 2-2 and 1-2 phase drive.
W1- 2 phase requires 4 tim es as muc h steps as 2-2 phase drive, calculating 2-2 phase as standard.
By using this method, it becomes possible to suppl y c onstant stable torque t o the motor. As a result, it
also became di ffi c ult to be i nfluenced by vi br ation f r om the pri nter mechanism during printing.

The figure below shows carriage mechani sm. The pri nt head as a core of the pr inting mechanism is stored
in the carriage unit. This print head k eeps the tilt of print head in f lexi ble and adjustable str uc ture by
moving the adjustment lever up and down by the tilt adjustment mechanism . (Refer to chapter 4 for more
details) Also, parall elism adjustment lever is mounted on the left and r ight side of carriage guide shaft and i t
adjusts parallelism degree between platen and shaft when this shaft is installed to t he pr inter m ec hanism.
After this adjustm ent is completed and operate PG adjustment lev er, it becomes possible to c hange the
space between platen surface and pr int head surfac e into 2 phases; either 1.1mm to 1.8mm. It is possible
to v ar y the space between platen surfac e and pr int head by rotating the axis of car r iage guide shaft which
itself is decentralized, wit h the operation of PG l ever. This i s the mechanism that user can adjust the
appropriate PG value by himself acc or ding to the paper t hickness or any other environmental conditions
such as paper curl.
Carriage loc k mechanism is to prevent the carriage from being l eft at unc ap posi tion f or a long time because
of vibrat ion during the pr inter transport or mishandling by the users. If the carri age is left at uncap
position and uncap stat e of the pr int head f or l ong t im e, an i nk on the pr int head surf ace gradual l y becom es
viscosity. As a result, the nozzle will be unable to discharge an ink. To make m atters worse, the
holes(crater) of nozzl e may be complet ely clogged by the viscosity i nk and it may not be able to return to
the normal condition just by cl eaning operation. In order to prevent this, printer goes to carriage lock state
at the f ollowing condi tions.
After Power OFF operation:
If t he power i s tur ned off on the way of printing or any other perform anc e, carriage lock will be
performed in the end after completing init ializ e oper ation.
After power ON o peration:
After power i s tur ned on and automatic P-On Cl eaning is perf or med, then car r iage lock will be
performed. P-On Cleaning is an automatic head c leaning that is performed when the power is
turned on. The t imer I C always calculates printer’s power OFF time by the power of lithium
battery mounted on the C200 m ain board. P-on cleaning function aut omatic ally 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 ejec ted, if the data i s not input, the pr inter
performs carriage l oc k and goes to standby state. However, if the paper i s l oaded to the print er
inside by Load/Eject butt on, the print er does not per form the carriage lock operati on.

2.1.1.2.1 Platen Gap Adjust Mechanism and Parallel adjustment Mechanism
This mechanism can be set by the users and can prevent vari ous problems relat ed to low image densi ty
or print wit h any dirt by changing the positi ons of PG lever acc or ding to the paper t y pes.

It is a m ajor premise that parallel adjustment is done corr ec tly for the space between head and platen
(PG adjustment value above) which can be changed by platen gap adjustment.
Parallel adjustm ent should be done when the serviceman mounts the carri age guide shaft on t he pr inter
mechanism during the produc tion process or repair servic e. In the adjustment, t he space bet ween
parallel adjustment lever and gauge should be 1.04 mm.

2.1.1.3 Paper Feed Mechanism and Pump Mechanism
Mechanisms that send the paper in the hopper to inside the printer and perfor m constant paper
feed in or der to perform print ing on the sent paper are called paper feed mechani sm as generic name.
In the Stylus Color 600, 4-phase, 200-pole hybrid t y pe pulse motor is used in the PF m otor as a moti ve
power of the paper mechanism and driv ing is done at 2-2 and 1-2 phase dri ve method. This motor i s
not only used as a power source for paper feed mechanism but al so used as power source of pum p
mechanism which is necessary for pr int head cleaning. By using t his pulse motor, it bec omes possible
to use high speed driver or intermi ttent dri ve for the various paper feeds and pump operations such as
paper feed, sl ight paper feed, high and l ow speed absorption of pump operations. Fol lowing tables(Table
2-7 and 2-8) show PF motor specifi c ations and control method at each mode.

Papers on the ASF (aut o- sheet- feeder) supplied by the user are carried to the pri nter inside by paper
pick up sequence. Unl ike the previous m odels, ASF of Styl us Col or 600 has mufti feed prevention
mechanism. Following expl ains this func tion and f igure below shows its mechanism.
[1. Mult i feed prevent ion mechanism]
When the Load/Eject button is pressed, reversed rotation of PF motor is performed.
The return l ever resets papers which are already in the out of stand by position in t he stand by posi tion
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 rotat es
countercloc k wise and makes the CAM rotat e towards direction of 1 in the figure above.
When the CAM c overs the not c h by the return lever, that position is considered as home
position, being moni tored by ASF sensor.
When the CAM r otates toward 1 in the figure above, the r eturn lever is pushed by the notc h
of CAM and fall s towards 2. At this time, the ret ur n lev er moves to direction 3 by this
moti on, and push down the pad which is waiting i n the below part. At this time, f r iction of
pinch roller and pad will be canceled.
The papers which are out of stand by position by the prev ious paper feed motion are
returned to the paper stand by posi tion by flip over strengt h of return lev er. After this,
PF mot or r otates clockwise and the printer goes to pic k up sequence.

2.1.1.4.1 Pump, Carriage Lock, Head Cleaner Mechanism
In the Stylus Color 600, ther e is no switch or mechanism to change over the pump/paper feed mechani sm.
Therefor e, whenever the paper feed/pump motor r otate, pum p dr iv e r oller i n the pump unit inside rotates.
However, ink absorpti on/non ink absorpti on ar e separat ed by the roller r otational directi on. Also, even if the
pump driver rotates toward ink absorpti on and the carriage position is in the fal se absorption position, only
driving in the pump m ec hanism 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 r oller by rotating the pinion of PF motor
is descried in figure 2-14. This motive power is conv ey ed to the Gear C thr ough Gear B.
In the f igure above, although the lever in order to drive Gear C, c ar r iage lock, head c leaner mechanism
is shown separately, it is constructed as one uni t. Si nce the engagem ent of these two parts depends on the
tension of the compression spring, if the lever is burdened, only Gear C and pum p r oller rot ate and no

The absorber is spread in the cap and c an hold a certai n amount of ink which i s absorbed from the
head without draini ng it to the waste ink pad. Also, i n the bott om of absorber, there are two v al v es in order

If t he c ar r iage is out of HP(in this case, in the printable area or paper feed position), the valves on the
cap mechani sm stays in the position A in the figure above and are always closed. In this condition,
the carriage c ollides with flag, ac tual ink absorpt ion and slight ink absorption are per form ed.
Also, by m ovi ng the carriage t o further r ight side and colliding the f lag for opening the valves with
the frame, negative pr essure is released in the state that head surface and cap are adher ed. This
makes it possible for ink on the nozzl e plate surfac e to be ready for leav ing from the cap i n the stable

2.2.1 C206 PSB/PSE Power Board
C206 PSB/PSE board is a power supply board with a RCC switching regul at or, which generates +42VDC for
driv e part and + 5VDC f or logi c part to dr iv e the pri nter. One of the m ajor char acteri stic of thi s board is that
the same secondary switch i s used as Styl us Col or series printer. By using this switch, the following
difference can be seen as superficial phenom ena c ompared with products applied with primary swit c h
method, such as Sty lus Color IIs, II and Stylus 800/1000 series printer. The table 2-12 below shows
application of volt ages generated by C206 PSB/ PSE board.
1) Even if the switch is turned off during the middle of pr inter operation, since the dr iv ing
power is turned off after t he c ar r iage goes back to the carr iage lock position,
the possibility of clogging ink nozzle will be decreased.
2) If the switch is turned off when the papers in t he pr inter are still being carried except for
the papers in the hopper, the same operation mentioned above is perf or med and the
driving power is turned of f af ter 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 i n the prim ar y
side of the power supply boar d from the mom ent or at the state that AC-plug is plugged in.
At this time, F1 plays a role of preventing AC100V from c oming i nto the F1.
L1 and R1-R2 also prevent high harmonic wave noise generated in the RC circuit filter whic h c onsi st
of C1•`C4 and R1•`R2 from goi ng out, and eli minate the noise from outside here.
2) The AC i s full- wave rectifi ed by diode bridge DB1, and c onvert ed to
electrolytic c apac itor C11.
3) The pressured up direct c ur r ent makes Q1 On through the starting resistor R31 and starts the primary
side of the c ircuit .
4) When the prim ary si de is On state, the energy(current) led by the electromagnetic induction through
the trans (T1) does not flow to the secondary si de si nc e the diode(D51) on the secondary si de
is installed in the opposit e directi on.
5) When the energy which is charged in the tr ans i s reaching the saturated stat e, the voltage which
makes the Q1 O n bec omes weak gradually. At the point that this vol tage drops at the
certain voltage, C13 absorbs the current in the opposite di r ec tion and Q1 i s qui c k ly shut off by
the resulti ng sharp drop.
6) When the primary side i s tur ned off, the energy charged in the T1 is opened according to the
diode(D51) dir ec tion which is i nstalled on the secondary si de. Basically, 42 V DC is output
by these circuit operati ons and the number of T1 spiral coil .

7) +5VDC i s generat ed by pr essured down this +42 V DC as power supply. IC51 pressures down the
+42 V DC and generates preci se + 5V DC by c hopping off the output, forming the standard santooth
wavef or m by the outer RC integration circuit.

Figure 2-18. C206 PSB/PSE Board Block Diagram
The C206 PSB/PSE board has various control circui ts to stop output if malfunction on the power supply
board, on the m ain board or on the duty of printer mechanism happen. Following explains each control and
protecti on c ircuit s.
1) +42V Line Constant Voltage Control Circuit:
The output l evel of the + 42V line is monitored by a detection circuit c onsi sting of seven Zener di odes.
This circ uit prevents voltage from dropping for c onstant output voltage.
2)+5V Line Over voltage Protection Circuit:
This protect ion circuit is in the same li ne as + 42V overvoltage protection circuit is located. The output
voltage level of the +5V line is monitored by a Zener diode. T his circui t shuts down the circuit oper ation
forcefull y when the voltage level ex c eeds + 9V.
3) +42VDC Line Over voltage Circuit
This ciruit is in the same li ne as + 5V line over voltage protection circuit is located. The output level is
monit or ed by two Zener diodes. If the voltage level exceeds +48V DC, this cir c uit stops circuit
operation forcef ully.
4) +5V Line Constant Voltage/Constant Current Control Ci rcuit:
The output curr ent is moni tored by a +5VDC generation switching c ontrol IC(IC51), which also
monit or s the output voltage. This information is input to the inter nal comparator and stabilizes+5V
line. A lso, operation of the secondary side switc h is explained below.
1) W hen the power is turned on, Q1 repeats ON/OFF automatically along with the inc r ease and
decrease of energy on t he trans coil at the prim ar y si de. W hile the power is bei ng on, PSC
signal is input to the power supply board from t he C200 main board.
2) This signal turns Q84 on and it becomes possible to discharge ener gy between 8-9 of T1.
At this time, even i f the power is turned off, the electrolytic c apac itor keeps Q84 on for a while.
By this elec trolytic capacitor, output is hold at least 30 seconds even after the power is tur ned off.
This time helps the printer to complete t he P - Off oper ation.

[CPU]
The C200 mai n boar d is controlled by a 16-bit CP U( TMP95C061AF) running at 25MHz. Gate array
manages most of control s and monitors. Likewise Stylus Color, the D-RA M is applied for RAM
which is used as work area for recei vi ng data and developing the dat a and CP U manages its control
such as CE, RAS/CAS controls.
[Gate Array]
E05B43 control s following functions.
Motor control : Eac h motor performs data transmission(W1-2 phase) that motives
Micro-Step.
Head voltage control: In the ink jet printers, dr iv e vol tage wave form(t r apez oidal wav e form )
in order to driv e P ZT is f or med in the various shapes according to the
types of the pr inters.
Therefor e, it i s necessary to form appr opr iate drive form for each head.
Head voltage control forms necessary wavefor m for eac h c ontrol
signals and outputs them.
EEPROM control: The correction value to elimi nate the error of each printers at the
production proc ess is installed in the fi xed address of IC.
When the power is turned off, the contents set by users is written
instantly, and is red to the RA M when the power i s tur ned on.
Sensor Data: The sensor detects i nform ation at the various conditions, whic h is
necessary for the printer operation. The gate ar r ay r ec ognizes signals
and changes over t o the next control.

Timer Data: The ti mer 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 ac c or ding to the time that the power is off .
[Common Dri ver IC]
The trapezoi dal wave form circuit for head dri ve i s became to HIC from t he pr evi ous di screate structure.
Because of this, it i s not nec essary to adjust the adjustable VR on the board duri ng pr oduc tion process.
Various electric charge/ discharge control si gnals are all proc essed in t he HIC.
[CR/PF Mo t or Drive Circui t ]
Constant current driv e is performed by the HIC. Out of this, only CR M otor is controlled f or M icro-Step
control and HIC becomes possible to flow the appropriat e current value at each steps. (PF Mot or has only
1-2, 2-2phase drive method). Also, bipolar drive is performed on the 4 cables i ndiv idually. Following
pages explain eac h major control ci r c uit.
Serial Data: The gate array recei ves serial data through the tr ansceiver IC.
Parallel I/F control: With the use of IEEE1284 Nibble mode, it becam e possible not only t o
receive the data from the host but also to ret ur n various information
which the print er possesses to the host.

2.2.2.1 Reset Circuits
The reset circ uit prevents the CPU from running away, which is caused by the unstabl e vol tage in the
logic line during the power ON/OFF. Also, this circuit monitors level of power voltage at the overloading
or malfunction on the circ uit and manages the pr inter to operate normal ly, keeping the damage to the
printer minimum during the abnorm al situations. On the C200 m ain board, 2 ICs are mounted ; IC for
monit or ing the voltage level (logi c line) and IC for m onitoring the voltage level ( power l ine) and both
are monitored by the gate arr ay and CP U.

The actual operat ion of t he c ircuit is to keep outputt ing Low signal until +5V l ine goes up to +4.2V
when the power is on, and to cancel t he r eset si gnal with output of High signal when the voltage goes up
more than 4. 2V.
[M51955(IC9)]
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 l ow and output by IC9 is input t o the CPU and gate array and system reset operation
is performed. Also, thi s signal is detected on t he IC9(IC f or r eset monitor, power li ne) and outputs the
same Low signal towards CPU/NMI t er minal by being input t o NC5.

2.2.2.2 Sensor Circuits
The following sensor circuits are mounted in the Stylus Color 600 and selects appropriate operations
based on the returned information.
ASF Sensor: An ASF sensor detects the position of return lever when the power is
(Photo) 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: A PE sensor determines if there is paper in the print er. Based on the
(Photo) signal form t his sensor, a partic ular paper edge treat ment such as
Micro-weav e printing is performed.
HP Sensor: A HP sensor detects the car r iage home posit ion.
(Photo) It i s used f or managing printing posit ion and cleani ng, etc.
Thermistor Sensor: A thermi stor sensor keeps stable printing quality, changing PZT dr iv e
voltage(VH) slightly acc or ding to changes of envi r onmental
temperature.
Cartridge Sensors: Cartridge sensors are built into the Bk, CMY cartridge on the carriage
unit respectively to determine i f the cartridge is i nstalled or not when it
is exchanged or t he power i s tur ned on. In case of Stylus Color 600,
the counter i s reset at every time the cartri dge is removed.
The fi gure below shows sensor circuit. Out of the data such as EPW with IEEE 1284 Nibbl e mode
to be returned to the host, the data t o indicate ink consumption is calculated and managed by the
counter of the fi r mware. Therefore, it is omi tted here.

The followings expl ain about operation of this circui t.
When the printer is on, power is supplied to t he Timer IC by appl y ing +5V qui c k ly through
the D4.
This power is also used for the power to oscillate the outer CR3. The oscillation wave form is
input to XIN t er minal .
Since the oscillation wave form of CR1 is analog wavef or m, 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 t o 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 t he lithium batt er y, the power is not being
consumed fr om the lithium battery.

Also, Stylus Color 600 has Micro- dot control as dot shooting control . There are tot al three dot shooting
controls on this printer.
• Norm al Dot mode( S ingle Firing)
• Norm al Dot mode( Dual Firing)
• Mic r o Dot mode
• Mic r o- Vi br ation(Not printed)
The control c ircuit is considered as two divided parts; 1) trapezoidal wave for m generati on c ircuit
(common drive circ uit) to driv e P ZT in the head, and 2) Nozzle-sel ec tor drive cir c uit to deter mine
which nozzle should be used. T he Noz z le-Selector is attached to the head unit just lik e the prev ious
models. T he c ommon driv e c ircuit is became as HIC and m ounted on the C200 main board.

If ink comes into contact with your skin, wash it off with soap and water. If irritation occurs,
contact a physic ian.
A lithium batter y is ins talled on the main board of this printer. Be sure to obser v e the following
instructions when servicing t he battery:
Keep the battery away from any m etal or other batt er ies s o that electrodes of the opposite
polarity do not come in c ontact wit h eac h other.
Do not heat the battery or put it near fire.
Do not solder on any part of the batter y. (Doing so may result in leakage of electroly te from the
battery, burning or explosion. The leak age m ay affect other dev ic es c los e to the battery.)
Do not charge the battery. (An explosive may be generated inside the battery, and cause burning
or explosion.)
Do not dismantle the battery. (The gas inside the battery may hurt y our throat. Leakage, bur ning
or explosion may also be resulted.)
Do not install the bat tery in the w r ong dir ec tion. (This may c aus e bur ning or ex plos ion.)
CAUTION
Danger of explosion if t he battery is incor r ec tly replaced. Replace only with the same or equiv alent type
recommended by the manufacture. Dis pos e the used batteries ac c or ding to government’s law and
regulations.
Risque d’explosion si la pile est remplacée incorrectment. Ne remplacer que par une pile du m ême type
ou d’un type équivalent recom mandé par le fabric ant. Eliminer les piles déchargées selon les lois et les
règles de sécurité en vigueur.
CAUTION
Never remove the ink c ar tridge from t he c ar r iage unles s m anual s pec ify to do so.
When transporting the printer after installing the ink cartridge, be sure to pack the printer for
transportat ion without rem ov ing the ink cartridge.
Use only recommended tools for disassembling, as s em bling or adjus ting the printer.
