Operating Principles
2.1 OPERATING PRINCPLES - OVERVIEW
This section describes the operating principles of the printer mechanism and the electrical circuits of the
Stylus Pro.
2.2 OPERATING PRINCIPLES OF THE PRINTER MECHANISM
2.2.1 Principles of the Printing Operation
The printing mechanism for the Stylus Pro XL+ has a drop-on-demand ink jet system, similar to the system in
all other EPSON ink jet printers. The Stylus Pro XL+ printer uses the Micro Dot printing function both with
black ink and super 720 dpi color printing. The type of Micro Dot printing the Stylus Pro XL+ performs is the
same as is available in the Stylus COLOR II and Stylus COLOR IIs/820. However, with those printers,
Micro Dot printing is available for printing with black ink only. The Micro Dot printing mode can be selected
automatically with 720 dpi printing quality using the printer driver settings described in the following table.

Normal Dot Printing
Micro Dot printing mode can improve output quality, because it eliminates banding that can sometimes occur
in normal mode. The dot size in EPSON Micro Dot Printing mode is smaller than the dot size in normal
printing. Normal print mode is mainly used in resolutions of 360 dpi or less.

2.3 OPERATING PRINCIPLES OF THE ELECTRICAL CIRCUITS
The Stylus Color Pro XL+ contains the following circuit board units:
❒
❒
❒
C184 MAIN board (main control circuit board).
C137 PSB/PSE board (power supply circuit board). This board is the same as Stylus Color’s
C137 PNL (control panel board). This board is similar to Stylus Color’s.
In addition to the circuit boards above, part of the printhead drive circuit is built on a separate circuit board
installed in the carriage unit; the printhead is attached directly to this board. The figure below shows a block
diagram of the electrical circuits.
2.3.1 Operating Principles of the Main Control Circuit
The main control circuit for this printer is the C184 MAIN board. This circuit is controlled by a 16-bit
H8/3003 CPU (IC1), running at 14.7456 MHz. The 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, both a 16-bit and an 8-bit data bus
width-type ROM can be used on the board, increasing the internal processing speed. Also, the CPU’s unique
architecture is capable of refresh control. In addition, the CPU controls the serial interface (RS-422 for Mac)
and optional interface (Type B interface).
Gate array E05B21 (IC2) manages the printhead driver, the external Centronics® parallel interface, the
extension CG board, and the control panel. The gate array also oversees the controls that create the 4-bit
signals for the carriage or the paper feed motor. (The carriage and paper feed motor are controlled by current
duty data.) This board also is equipped with a 93C46 EEPROM (IC11) to store certain parameters, such as the
black/color head data, printer mechanism control parameters, default setting parameters, as well as a special
counter value used for printhead (ink management) protection.
Timer IC NJU6355E (IC10) counts each time the printer goes through its cleaning cycle and keeps track of
how much time has elapsed since the printer has been used, thereby allowing the printer to be cleaned only
when necessary. The timer value is backed up by the lithium battery.

2.3.2.1 Reset Circuits
The C184 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 (logic line), using reset IC
PST592D (IC9), and outputs a reset signal to the CPU (IC1) and the E05E21 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 C184 MAIN board to monitor printer mechanism status:
HP sensor
A photocoupler-type HP (home position) sensor is attached to the surface of the printer
mechanism to detect the carriage home position. A HIGH level from the signal indicates
that the carriage is in home position.
PE sensor
A mechanical switch PE (paper end) 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
Micro switches (BCO sensor for the black ink cartridge, CCO sensor for the color ink
cartridge) are attached to the bottom of 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. These sensing
timing is only in the cartridge installation mode and one minute after the carriage holed to
prevent from miss censoring owing from switch actuators shock in printing condition.
Thermistor
A thermistor is attached to the color printhead driver board to monitor its temperature using
the thermistor’s resistance value (at 25° C (77° F), the normal value is approximately
10K Ω). The CPU changes the printhead drive signal’s pulse width (charge pulse width)
based on the temperature level.

Operating Principles
2.3.2.3 Carriage Motor Driver Circuit
Carriage motor driver IC SLA7043 (IC15) outputs a constant current to drive the carriage motor in the printer
mechanism. Gate array E05B21 (IC2) decides the motor phase and speed, and then it sends a signal to the
carriage motor driver IC (SLA7043), using the 4-bit serial transmission line. The first bit indicates the
direction of motor rotation. The other three bits (a, b, c) are current duty data for the motor speed for each
printing sequence. (Refer to Table 2-2, below.)
SLA7043 can select the reference voltage itself based on these three bits of current duty data. Also, the driver
IC receives these signals via two serial transmission lines for the two motor phases (phase A and phase B). As
a result, the carriage motor can be driven in micro step sequence (1⁄720 inches, minimum). The SLA7043
motor driver reads four-bit serial data using four clock counts from the E05B21 (IC2) clock.
Each bit is read at the falling edge of the clock pulses. Then, received serial data is written into the shift
register and then shifted the latch register. When the strobe pulse becomes active from the E05B21 (IC2),
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.

2.3.2.5 Printhead Driver Circuit
The printhead driver circuit for this printer is composed of the following two parts:
❒
❒
Common driver circuit (common drive pulse generation)
Head driver circuit (nozzle control built on the printhead)
The common driver circuit is hybrid IC H8D2778A on the C184 MAIN board. The head driver circuit is IC
SED61110D0A on the printhead unit itself. The printhead drive signals are output from gate array E05B21.
They consist of the common driver control signals (SBDT/SCDAT, SCLK, SSTB, SCLR, BH1C0/CH1C0,
BH1C1/CH1C1, BH1D/CH1D, BHDIS/CHDIS) and the nozzle select signals (BHDAT/CHDAT,
BHCLK/CHCLK, BHLAT/CHLAT, BHNCHG/CHNCHG).
The common driver control signals from gate array E05B21 are translated to common drive voltage pulses by
IC H8D2778A and input to each printhead nozzle PZT. The nozzle select signals are also output from gate
array E05B21 to SED6110D0A on the head unit to select the print nozzles. Then the ink dots are ejected from
the selected nozzles.

Common Driver Signals
The common driver control signals consist of the common voltage control signals (SBDAT/SCDAT, SSTB,
SCLR, SCLK) and the common drive pulse generation signals (BH1C0/CH1C0, BH1C1/CH1C1,
BH1D/CH1D, BHDIS/CHDIS). The common voltages (VH), ranging between the maximum voltage and 0
(V), are split into 256 levels, which are then translated into 8-bit serial data for the common voltage control
signal (BHDAT/CHDAT), which is output from gate array E05B21 to the common driver H8D2778A to fit
with each printhead specifically. The signals are received by SSTB, SCLR and SCLK to the common driver.

Nozzle Select Signals
The nozzle select signals are output from gate array E05B21 to SED6110D0A on the head unit to select the
printhead nozzles. Nozzle select data (BHDAT/CHDAT) is HIGH for selected nozzles and LOW for
unselected nozzles. Nozzle select data translation timing is controlled by 64 clock signals (BHCLK/CHCLK),
one for each nozzle. After the print nozzles are selected, the common drive pulses are input to each PZT on
the selected nozzles via SED6110D0A. Then the ink dots are ejected from each selected nozzle’s PZT.

Normal Dot Versus EPSON Micro Dot Printing Mode
The Stylus Color Pro XL+ can eject ink in two different modes (normal print mode and EPSON Micro Dot
Mode). These modes are the same as the modes used in the Stylus Color II/Stylus Color IIs. (Refer to Section
2.2.1.) However, EPSON Micro Dot Printing in the Stylus Color II and Stylus Color IIs can be used only for
printing with black ink. EPSON Micro Dot Printing in the Stylus Pro XL+ can be used with both black and
color printing.
In normal dot printing, a pair of common drive pulses are translated to the printhead to produce one dot. On
the other hand, one print dot consists of single dot in the EPSON Micro Dot Printing. A single common drive
pulse is translated to the printhead, as shown in the following figure.

2.4 INK SYSTEM MANAGEMENT
This section explains how the ink system is managed to protect the printhead and the ink supply system and to
ensure high-quality output. Ink system operations are controlled by the following counters:
❒
Protect counter
❒
Ink consumption counter
2.4.1 Counters
EEPROM 93C46 (IC11) on the main board stores the counter values used for controlling ink system
operation.
2.4.2.1 Protect Counters
The values of protect counters A and B, C are stored in the EEPROM on the main board, and while the printer
is on, this data is also stored in the RAM on the main board.
❒ Protect counter A
This counter manages the total amount of drained ink. If the counter value
is equal to or exceeds 51,000, the printer indicates an error on the control
panel indicating that maintenance is required.
Notes for Service
Protect counter A is reset:
1. Upon shipment from the factory.
2. After maintenance is performed (whenever you replace the ink drain tank).
❒ Protect counter B, C
These counters set limits to prevent the user from frequent initial ink
charging. The counters values are stored in the EEPROM as flags and are
reset by the EEPROM reset function.
2.4.2.2 Ink Consumption Counter
This counter manages black and color ink consumption. The counter is counted up during printing,
automatically. It also counts compulsory head cleaning and the interval times between usage of the ink
cartridge. This counter is only reset by the installation of a new ink cartridge.

4.1 ADJUSTMENT - 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.
CAUTI
O
N
❏ Always perform adjustments in the order indicated.
❏ After performing steps 1-5, do the cleaning operation for the black and color printheads.
The cleaning operation is necessary, 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

Figure 4-10. Relationship between the Shape and Thickness
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.

In Figure 4-9, pay attention to the position of A and B while you reset the left angular spacer. The
replacement procedure is explained beginning in step 6.

In Figure 4-14, 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 6-10.
CAUTION
❏ 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.
6.
Turn the printer off.
7.
Move the carriage to the center while pressing the carriage lock lever, and remove the two ink cartridges.
8.
Remove the rubber cap that covers a head screw at the side of color ink cartridge, and then loosen (but

CAUTION
After replacing the spacer, always install new ink cartridges before returning the printer to the
user. During adjustment, use the ink cartridges exclusively for service (Monochrome: 1020626,

4.1.7 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 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 C184 MAIN
board and refers to this data when performing bidirectional printing.
