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.

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
signal’s active edge.

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.

The BUSY signal informs the host computer of the printer’s

Stylus Pro XL Product Description

1.5 MAIN COMPONENTS

The main components of the Stylus Pro XL are:

❏ Printer mechanism (M-4A60)
❏ Main control board (C162 MAIN Board)
❏ Power supply unit (C137 PSB/PSE Board)
❏ Control panel board (C137 PNL Board)
❏ Housing

1.5.1 Main Control Board (C162 MAIN Board)

The Main Control Board (C162 MAIN Board) consists of an H8/3003 16-bit CPU, E05A96 gate array, a
program ROM (4M), a dynamic RAM (4M), a mask ROM (4M or 8M), an EEPROM (1K), and a lithium
battery for powering the protect counters. The reset IC (M51955 and PST 592) is equipped with both a logic
system and a power system. The 8M program ROM is used only for the NLSP (National Language Support
Printer) specification.

Rev.A 1-19

Product Description Stylus Pro XL

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.

1.5.3 Control Panel (C137 PNL Board)

The 14 LEDs on this board indicate the error status (there is no buzzer system); by using the 6 switches in
combination with one another, the printer can operate in each protect operation (color or black cleaning,
cartridge exchanging, self-test, default setting value exchanging, reset, and EEPROM clear operation).

Stylus Pro XL Product Description

1.5.4 Printer Mechanism (M-4A60)

The M-4A60 printer mechanism is equipped with a 64-nozzle black printhead and 48-nozzle color (CMY)
printhead on the carriage unit. Resolution of 720 dpi is possible with special (non-absorbent) paper.

The ink system has both a black pump unit and a color pump unit. Waste ink from each printhead is made to
flow into the individual caps. Power for the pump system and paper feed system is supplied from the paper
feed motor.

Figure 1-11. Printer Mechanism (M-4A60)

1.5.5 Housing

The Stylus Pro XL housing consists of the printer cover, upper case, and the lower case. Attached to the
housing are the front paper support and the ejected paper support with paper separator.

Operating Principles Stylus Pro XL

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.

Stylus Pro XL Operating Principles

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.)

REV.-A 2-3

Operating Principles Stylus Pro XL

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.
