Signal Name
STROBE
DATA 1-8
I/O*
Description
I
The STROBE pulse is used to read data from the host
computer. The pulse width must be 0.5 µs or more. Normally,
it is HIGH, and data is latched with the rising edge of this
signal.
I
DATA 1-8 are parallel data bits. When one of these signals is
HIGH, the data bit is 1; when LOW, the data bit is 0. The
most significant bit (MSB) is DATA 8. The signal state must
be maintained for 0.5 µs on either side of the STROBE
signal’s active edge.
10
ACKNLG
O
ACKNLG is an acknowledge pulse with a width of
approximately 10 µs. This signal goes LOW upon the
completion of data reception to indicate that the printer is
ready to receive further data.
11
BUSY
O
The BUSY signal informs the host computer of the printer’s
status. When this signal is HIGH, the printer cannot accept
any more data.
12
PE
O
This signal indicates whether paper is available in the printer
or not. A HIGH level indicates no paper.
13
SLCT
O
Pulled up to +5 V through a 1.0 KΩ resistor in the printer.
14
AFXT
I
If this signal is set to LOW, the printer automatically performs
one line feed upon receipt of a CR (carriage return) code. The
status of this signal is checked only at power on and
initialization.
31
INIT
I
If this signal goes LOW, the printer is initialized. The pulse
width of this signal must be 50 µs or more.
32
ERROR
O
This signal goes LOW if the printer has a fatal error or runs
out of paper.

1.5.2 Power Supply Board (C137 PSB/PSE Board)
The power supply board (C137 PSB/PSE Board) consists of an RCC switching regulator circuit. This board is
equipped with a power switch connected to the secondary circuit. Thus, if the printer is turned off, it can
continue to operate in order to eject the paper and perform the head capping operation. The power on/off
signal is always monitored by the E05A96 gate array on the C162 MAIN Board, and the logic system
recognizes the power switch status.

2.2.1 Printer Mechanism
The printer mechanism of this printer uses a drop-on-demand ink jet system similar to the system
used on all other EPSON ink jet printers. However, the printhead in this system is completely
redesigned to make it more compact and ensure a high level of reliability. The figure below shows
the structure of the printhead and ink supply system.
❏Piezo
When a drive pulse (voltage) is applied, this element pushes the vibration plate,
compressing the cavity for ink injection from the nozzle.
❏ Cavity
Ink supplied from the ink cartridge is stored in this space and is ejected fr
om the nozzles when the vibration plate compresses this area.
❏ Nozzles
These eject ink against the paper’s surface in response to the application of the
print signal. There are 64 (black head) or 48 (color head) individual nozzles
making up the printhead.

Principles of the Printing Operation
The printhead operates in one of two modes to eject ink from each nozzle:
❏
Normal state
No electrical charge is applied to the MLP (Multi-Layer Piezoelectric) element attached to the
back of the cavity, and pressure inside the cavity is kept at a constant level.
❏
Ejecting state
The head data signal is applied to the specific nozzle control line to select the active nozzle for
printing, and the MLP element is gradually charged by the drive voltage. By charging the MLP
element, the vibration plate is bent to compress the cavity. Then, ink is ejected from the nozzle.

Figure 2-3. Principles of the Printing Operation
When the ink charge or printhead cleaning operation is performed, the ink in the cavity is
vacuumed out with the pump mechanism. During printing, on the other hand, the ink is
simultaneously supplied from the ink cartridge and ejected from the nozzle, according to the
change of volume in the cavity.
A thermistor is attached to the side of the color printhead drive board to monitor the temperature,
because the viscosity of the ink varies, depending on the temperature. The detected temperature
level is fed back to the printhead drive voltage control circuit to change the timing of the Tc pulse.
(The Tc pulse is shown in Section 2.3.2.5.)

Micro Dot Printing mode
The Stylus Pro XL printer has a special printing mode, called “Micro Dot Printing mode”. This
printing mode can be selected by a command from the host computer. Using the Micro Dot
printing mode can improve the quality of output. In Micro Dot Printing mode, the ink dot size
became to be smaller than the normal dot size.

2.2.2 Carriage Drive Mechanism
The timing belt attached to the base of the carriage unit is driven by the carriage motor, causing the
carriage unit to move along the carriage guide shaft left to right, or vice versa. The carriage drive
motor on this printer is a 4-phase, 200-pole, hybrid-type stepping motor mechanism, allowing the
printer to stop the carriage or change the carriage movement at any position. The position of the
carriage is recognized by the home position sensor, and position information is fed back to the
carriage drive control circuit. This carriage motor is driven by the motor driver IC SLA7041 (see
Section 2.3.2.3 for more information).

2.2.3 Paper Feed Mechanism
This printer’s paper feed mechanism can feed paper only from the built-in ASF (auto sheet feeder).
The paper feed drive motor is a 4-phase, 96-pole, hybrid-type stepping motor that directly drives
the paper feed mechanism (paper advancing operation, paper pickup operation). This motor also
drives the pump mechanism, but only when the printer is in the cleaning state. The paper feed
drive method is driven by the 2-2 phase drive method, except the paper feed drive sequence
(2 W1-2 phase).

The pump draws ink from the printhead nozzles and drains it to the waste ink drain tank. The
printer performs this operation to eliminate dust or bubbles in the nozzles. Figure 2-12 illustrates
pump operation. When the paper feed drive motor rotates CW (forward), the color pulley pumps
in the wheel pump unit rotate in the direction of the arrow while squeezing the ink tube to push the
ink inside the tube out to the waste ink drain tank. When the motor rotates CCW (backward), the
black pulley pumps in the wheel pump unit rotate in the direction of the arrow while squeezing the
ink tube to push the ink inside the tube out to the waste ink drain tank.
There are two pump rollers in the pump unit, and the drive power is supplied from the paper feed
motor via the pump drive gear (D/E gear), which is moved by carriage operation. In the pump
unit, the transmission gear drives both the black and color pulley, which are rotated by the
movement of the other.

2.2.6 Cap Mechanism
The cap mechanism prevents the printhead nozzles from drying and keeps bubbles from forming
inside the nozzle while the printer is not in use. The printer performs this operation automatically
when print data is not received or when the printer power is turned off during printing or ink
system operations. (The secondary circuit for the power switch allows this operation to be
performed.) Also this printer has two caps, one for the black head and one for the color head.

gear. When the wiper is raised (against the printhead surface), the hook for securing the carriage to
the home position is raised, too. When the wiper goes down toward the bottom frame, the hook
goes down, too. Both black and color heads are cleaned by this wiper.

The power supply circuitry for this printer is provided either by the C137 PSB Board (120 VAC) or
the C137 PSE Board (220-240 VAC). Both boards are identical in design and functionality, except for
the components in the primary circuit that accommodate the specified input voltage. The input

Operating Principles
Stylus Pro XL
The figure below shows a block diagram of the power supply circuit (C137 PSB/PSE). The power
switch is equipped with a secondary circuit that allows the CPU to remain active for a while after
the printer is turned off. This allows the printhead to return to the capping position after power is
off. The CPU mounted on the C137 MAIN Board always monitors the PSC (power on/off) signal. If
this signal becomes LOW, the CPU resets each device after performing the head capping sequence.
Also, this board employs the RCC (ringing choke converter) switching system. This AC voltage is
first input to the filter circuit for higher harmonics absorption, and then input to the rectification
and smoothing circuit, converting it into DC voltage. This DC voltage is then input to the switching
circuit for the switching operation. Along with the switching operation on the primary side, +35
VDC is generated after passing through the +35 V line voltage detection circuit. This +35 VDC
output level is stabilized. This +35 VDC is also input to the +5 VDC generation circuit to generate a
stable +5 VDC.

to stop the +35 V generation.
2) +5 VDC line over current / over voltage control circuit.
The output current is monitored by a detection resistor (R53) and fed back to the +5 VDC

2.3.2 Operating Principles of the Main Control Circuit
The main control circuit of this printer is the C162 MAIN Board. This circuit is controlled by the
16-bit CPU H8/3003 (IC1), running at 14.7456 MHz. This CPU has a unique architecture capable of
handling data on the data bus at either an 8-bit or 16-bit bus width. Because of this, a 16-bit or 8-bit
data bus width-type ROM is used on this board, increasing the internal processing speed. Also, the
CPU has a unique architecture capable of the refresh control function. A 4M DRAM (2 CAS
method) on this board is controlled by the CPU itself. The CPU controls the serial interface control
(RS-422 for Mac).
Gate array E05A96 (IC2) manages printhead drive control, external Centronics® parallel I/F,
extension CG board and the control panel, and the controls that create the 4-bit signal for the
carriage or the paper feed motor. (The carriage and paper feed motor are controlled by the current
duty data.)
This board also is equipped with EEPROM 93C46 (IC12) to store certain parameters, such as the
printer mechanism control parameter, default setting parameters, as well as a special counter value
used for printhead (ink management) protection.
The timer, IC NJU6355E (IC7), counts each time the printer is cleaned and keeps track of how long
the printer is not used, thereby allowing the printer to be cleared only when necessary.

2.3.2.1 Reset Circuits
The C162 MAIN Board contains 2 reset circuits: the +5 V monitor reset circuit and the +35 V
monitor reset circuit. The +5 V monitor reset circuit monitors the voltage level of the +5 V line,
using reset IC PST592D (IC12), and outputs a reset signal to the E05A96 gate array (IC2) when the
voltage level drops below +4.2 V. The +35 V monitor reset circuit monitors the voltage level of the
+35 V line, using reset IC M51955B (IC8), and outputs a reset signal to the CPU. The reset signal is
generated when the voltage level drops below +28 V, and this causes a non-maskable interrupt
(NMI).

2.3.2.2 Sensor Circuits
The following sensor circuits enable the C162 MAIN Board to monitor printer mechanism status:
HP sensor
The photocoupler-type home position (HP) sensor is attached to the surface of the
printer mechanism to detect the carriage home position. A LOW level from the
signal indicates that the carriage is in home position.
PE sensor
The mechanical switch paper end (PE) sensor is built into the printer mechanism to
determine whether there is paper in the printer or not. A LOW level from the signal
indicates that no paper is loaded.
BCO sensor,
CCO sensor
The cartridge out (CO) sensor is micro switch attached to the bottom of each ink
cartridge holder in the carriage unit. When the ink cartridge is installed, these
switches are pressed and a LOW level from the signal indicates that the ink
cartridge is installed into the ink cartridge holder.
Thermistor
A thermistor is attached to the color printhead driver board to monitor its
temperature by thermister’s resistance value (at 25°C approx. 10kΩ). The CPU
changes the printhead drive signal’s pulse width (charge pulse width) based on the
temperature level.

2.3.2.3 Carriage Motor Drive Circuit
The carriage motor drive IC SLA7041MS (IC15) outputs a constant current to drive the carriage
motor for the printer mechanism. Gate array E05A96EA (IC2) decides the motor phase and speed
and then sends a signal to the carriage motor driver IC (SLA7041MS) using the 4-bit serial
transmission line.
The first bit indicates the direction of the motor rotation. The other three bits are current duty
data for the motor speed of each printing sequence. SLA7041MS can select the reference voltage
itself based on these three current duty data. Also, it receives these signals by 2 serial
transmission lines for 2 motor’s phases (phase A and phase B). Due to this, the carriage motor
can drive the micro step sequence (min. 1/720 inches).

Four-bit serial data is read by the SLA7041MS motor driver with four clock counts from the
E05A96 (IC2) clock. Each bit is read at the falling edges of these clock pulses. Due to this,
received serial data is placed in the shift register and then shifts the latch register. When the
STROBE pulse becomes active from the E05A96 (IC2), the serial data is moved into the reference
voltage selection circuit, and the voltage is changed. Therefore, when the printer is in the
constant speed mode, this STROBE pulse becomes inactive. The following table indicates the
current duty of each carriage motor speed mode.

The printhead drive circuit for this printer is composed of the following two parts:
❏
❏
Common drive circuit (trapezoidal drive pulse generation)
Head drive circuit (nozzle control built on the printhead)
SED5620D, the 64-bit thermal head driver in the head drive circuit on the carriage, is used as a
nozzle selector to drive the printhead nozzles selectively. Print data is converted into serial data by
gate array E05A96 (IC2) and is output from port BSO (pin 20) to the black head drive circuit or
output from port CSO (pin 24) to the color head drive circuit. Then, head driver SED5620D latches
the head data when gate array E05A96BA outputs the BLAT or CLAT signal, and the latched data
becomes 64-bit parallel data for the black head, or 48-bit parallel data for the color head. One bit
corresponds to each nozzle.
When data transfer and nozzle selection is complete, gate array E05A96 outputs the common drive
pulse BPWC or CPWC (charge pulse) and BPWD or CPWD (discharge pulse) to the common drive
circuit. The common drive circuit then generates the trapezoidal pulse and applies it to the
printhead as a common drive pulse. After this, the nozzle selected by the head data is activated to
inject ink.
In the Micro Dot Printing mode, the gate array E05B09 arranges the puise width of CPWC and
CPWD to became small size of injection ink dot.

2.3.2.6 DMA Controller
Data from the host computer is received automatically by the STB signal via the external Centronics
interface. The data is input to the input buffer on the DRAM (IC5). At this time, E05A96 detects the
rising edge of the external STB signal and outputs the STBDMA (strobe DMA request) signal to the
CPU. When the CPU detects this signal, the DMA controller in the CPU sends a bus request to the
bus controller in the CPU, and then the CPU releases the bus line. Due to this, external data is
transported into the memory, bypassing the CPU.

Operating Principles
2.4.1 Ink Operations
Various ink operations can be performed selectively by the printer.
1 Power On Operation
This operation is performed when power is turned on.
2 Cleaning Selection Mode
This operation cleans each nozzle to ensure that the nozzle fires and that no dots are skipped
during printing. Cleaning selection is performed by pressing the cleaning switch (Alt +
Load/Eject or Economy/Condensed) while the printer is in PAUSE status.
3 Micro Absorbing Cleaning Operation
This operation prevents an increase in the viscosity of the ink inside the printhead by ink
absorbing discharge.
4 Power Off Operation
This operation ensures the carriage is in the home position when the printer turns off, and
prevents the disengage gear from turning continuously when the printer turns off. Power off
operation is performed when the secondary side switch is turned off.
5 Print Start Operation
This operation eliminates ink from the nozzle surface, and is performed when the printer
receives print data while in the standby state.
6 Refresh Operation
This operation prevents an increase in the viscosity of the head ink.
7 Standby Operation
This operation prevents an increase in the viscosity of the head ink.
8 False Absorbing Operation
This operation absorbs ink inside the cap, and eliminates ink from the nozzle plate.
9 Ink Cartridge Replacement Operation
This operation is performed when the Alt button is pressed for more than 3 seconds; the carriage
then moves to the ink cartridge replacement position.
10 Wiping Operation 1
This operation eliminates dust from the nozzle plate before performing the ink absorption.
11 Wiping Operation 2
This operation eliminates dust or ink from the nozzle plate after performing the ink absorption.
12 Rubbing Operation
This operation removes dust or ink that adheres to the head surface.
13 Disengage ON Operation
This operation sets the switch lever to the position where it transmits the PF motor drive to the
pump mechanism. It also moves the carriage to the home position where the lever is set to the
specified position.

Operating Principles
Stylus Pro XL
14 Disengage Off Operation
This operation resets the switch lever to the position where it transmits the PF motor drive to the
pump mechanism. It also moves the carriage to the flushing position, where the lever is reset to
the specified position.
15 Micro Absorbing Operation
When the cartridge is removed, it is possible for a small amount of air to form small air bubbles
that can block the ink from the nozzle. This operation eliminates small air bubbles from the
cavity of the printhead.
16 Carriage Lock Set
This operation prevents the carriage from moving out of the home position if the printer is
turned off or is pauesd. This operation is performed when the carriage is in the ink system home
position and no paper is loaded.
17 Carriage Lock Reset
This operation resets the carriage lock lever.
18 Refresh Operation (Performed when Loading or Ejecting Paper)
This operation prevents an increase in the viscosity of ink inside the black head while paper is
being loaded or ejected. When paper is loaded or ejected, just the black head is ready, and the
color head is capped. The refresh flushes the black head only.
19 Adjust Lever Position Moving Sequence
This operation is performed when the Alt and Font buttons are pressed simultaneously while the
printer is paused.
20. Transportation Sequence
This sequence is performed to clean the printhead when the printer is transported to the market.

4.1 OVERVIEW
This section describes adjustments required when the printer is disassembled and assembled after
repair. Since this printer has both a black and color head, it needs new adjustments not required for
previous printers. Refer to the following table to perform the appropriate adjustments.
WARNING
❏ Always perform the adjustments in the order indicated.
❏ After performing steps 1-5, perform a cleaning operation for the black and color
printheads. the cleaning operation is needed because printing sample patterns for the
head angle, Bi-D alignment, and the head gap increases the viscosity of the ink, and the
printer will not print the correct value. For instance if you replace the black head, you
must do the following adjustments in the order shown:
(1) Black head angle, (2) black-color head vertical, (3) head gap, (4) Bi-D alignment.
❏ After removing an ink cartridge, always install a new cartridge immediately. During
adjustments and testing, use cartridges designed exclusively for service
(Monochrome: 1020626, CMY: 1020627).

4.1.1 Destination Data Writing Operation
The setup value that specifies the printer destination is stored in the EEPROM on the C162 MAIN
board. Therefore, this setup value must be written into the EEPROM when the MAIN board or
EEPROM chip is replaced.
CAUTION
Before writing the destination data writing, set the interface to parallel.
1.
Connect the PC to the target printer using a parallel interface cable and turn the printer on.
2.
Execute BASIC on the PC, and run the program “VERxxx.BAS.” You see the following menu.

4.1.2 Bi-D (Bidirectional Printing) Alignment Adjustment
The bidirectional alignment is required when the printer mechanism, main board, or printhead
(board) is replaced. Performing this adjustment determines a compensation value to rectify any
deviation in the print position. This deviation could be caused by the different print speeds, which
are due to tolerances in the mechanical components, or to differences in print timing between
odd-numbered lines and even-numbered lines in bidirectional printing. The printer stores the
compensation data in the EEPROM on the C162 MAIN board and refers to this data when
performing bidirectional printing.

4.1.4 Black Head Angle Adjustment
The black head angle adjustment is required when the black head is replaced or disassembled. If
this adjustment is not correct, a white banding problem may occur, or the color head timing may
not match the black head timing. The following figure illustrates the black head angle adjustment.
The black head angle is adjusted with linear and angular spacers. A linear spacer is attached to both
sides of the head base, and an angular spacer is attached only to the right side of the head base.
Spacers for the black head come in different shapes for the thickness needed. The following figure
shows the relationship between the shape and thickness.

This adjustment calibrates the vertical position between the black head and the color head. Align
the top nozzles (both nozzle #1 on the black head and nozzle #1 on the color head). You can make
this adjustment by using only the linear spacers for the black head. This adjustment is required
when the black head or the color head is replaced or disassembled. The following figure illustrates

In Figure 4-10, the vertical position is correct when both the magenta line and the black line
are aligned (as shown in position OK (0)). If the vertical position is correct, turn off the
printer. If the black and magenta lines are not aligned, perform the vertical adjustment as
described in steps 5-10.
WARNING
❏ The number shown in the sample indicates the thickness level compared to the current
linear spacer. (See * .) There are 11 linear spacers with 11 different thicknesses.
❏ The linear spacer is attached by two pieces, one on each side of the head base. Therefore,
when you need to replace one linear spacer, always replace both linear spacers at the
same time.
❏ When replacing the linear spacer, place it under the angular spacer.
*
If necessary, replace the linear spacer. For instance, if your pattern is similar to the pattern
shown under –2, replace the linear spacer with a thinner linear spacer. If your pattern is similar
to the pattern shown under 2, replace the linear spacer with a thicker spacer.

The color head angle adjustment is required when the color head is replaced or disassembled.
If this adjustment is not correct, a white banding problem may occur, or the black head timing may
not match the color head timing. The following figure illustrates the color head angle adjustment.
The color head angle is adjusted by the angular spacer. The angular spacer is attached only to the

Adjustments
Angular spacers for the color head come in five thicknesses, each having its own shape. The
following figure shows the relationship between the shape and thickness. Since the color head is
not equipped with a linear spacer, the angle adjustment is decided only by the angular spacer
(specifically designed for the color head), which is placed under the left side of the head base.

Maintenance
6.1 PREVENTIVE MAINTENANCE
Although this printer is designed so that no specific maintenance is required on a regular basis, it is
recommended that you clean the printer thoroughly whenever you get a chance to do so. You can clean:
❒
Outer case
Use a soft, clean cloth, dampened with mild detergent, if necessary.
❒
Auto sheet feeder
If the inside of the auto sheet feeder is dirty (dusty), carefully brush away all dust and dirt using a soft
brush. If the pickup roller of the sheet feeder is dirty, clean its surface with a soft, clean cloth.
❒
Inside the printer
If you notice any dust or dirt that has accumulated inside the printer when you open the outer case for
repair, remove all dust and dirt using a small vacuum cleaner designed for such purposes.
WARNING
❒ Never use paint thinner, trichloroethylene, or ketone-based solvents for cleaning. These
chemicals can damage the components of the printer.
CAUTION
❒
❒
❒
Do not use a hard or abrasive brush for cleaning.
Be careful not to damage the components of the printer when using a vacuum cleaner.
A lithium battery is installed on the C164 MAIN board of this printer. Be sure to observe
the following instructions when servicing the printer or storing the after-service parts:
1. Keep the battery away from any metal or other batteries so that electrodes of opposite
polarity do not come in contact with each other.
2. Do not heat the battery and place it near fire.
3. Do not solder on any part of the battery. (Doing so may result in leakage of electrolyte
from the battery, burning, or explosion. The leakage may damage devices close to the
battery.)
4. Do not charge the battery. (An explosive gas may be generated inside the battery, and
cause burning or explosion.)
5. Do not dismantle the battery. (The gas inside the battery may hurt your throat. Leakage,
burning, or explosion may also result.)
6. Do not install the battery in the wrong direction. (This may cause burning or explosion.)

Maintenance
Stylus Pro Service Manual
6.2 SERVICE MAINTENANCE
Certain maintenance is required when the printer detects an error or when a decline in print quality is
observed.
6.2.1 Printhead Cleaning
If print quality deteriorates, clean the printhead using the built-in printhead cleaning function. The printer also
has an automatic printhead cleaning cycle to ensure the proper nozzle operation for ink injection as well as to
preserve its best condition. Therefore, perform this printhead cleaning operation only if print quality declines
to avoid wasting ink.
1.
Turn the printer on and press the Pause button to pause the printer. Make sure that the PAUSE LED is
on.
2.
Hold down the Alt button and press the Load/Eject button for black head cleaning.
Hold down the Alt button and press the Economy/Condensed button for color head cleaning.
When panel button operation is accepted by the printer, the PAUSE LED flashes during the cleaning cycle.
When the cleaning completes, the PAUSE LED stops flashing and the printer returns to standby mode.
6.2.2 Waste Ink Drain Tank Replacement
The printer counts the total amount of ink drained to the waste ink drain tank and this information is stored in
the EEPROM on the main board (in Protect Counter A). This value is used for ink system operation
management. If the counter value reaches the predetermined value, the printer displays an error (“Waste ink
tank overflow,” see Chapter 1, Section 1.4.4, Error Conditions, Table 1-10). When this error is displayed,
replace the waste ink absorbing materials and reset the protect counter.
1.
Open the upper case and replace the waste ink absorbing materials from the compartment of the lower
case. Reassemble the printer.
2.
Turn the printer while holding down the Alt, Font, Load/Eject, Pause buttons. This resets the protect
counter.
