Signals a precaution which, if ignored, could result
in damage to equipment.
DANGER
1. ALWAYS DISCONNECT THE PRODUCT FROM THE POWER SOURCE AND PERIPHERAL DEVICES PERFORMING ANY MAINTENANCE OR REPAIR
PROCEDURES.
2. NOWORK SHOULD BE PERFORMED ON THE UNIT BY PERSONS UNFAMILIAR WITH BASIC SAFETY MEASURES AS DICTATED FOR ALL
ELECTRONICS TECHNICIANS IN THEIR LINE OF WORK.
3. WHEN PERFORMING TESTING AS DICTATED WITHIN THIS MANUAL, DO NOT CONNECT THE UNIT TO A POWER SOURCE UNTIL
INSTRUCTED TO DO SO. WHEN THE POWER SUPPLY CABLE MUST BE CONNECTED, USE EXTREME CAUTION IN WORKING ON POWER
SUPPLY AND OTHER ELECTRONIC COMPONENTS.
WARNING
1. REPAIRS ON EPSON PRODUCT SHOULD BE PERFORMED ONLY BY AN EPSON CERTIFIED REPAIR TECHNICIAN.
2. MAKE CERTAIN THAT THE SOURCE VOLTAGES IS THE SAME A S THE RATED VOLTAGE, LISTED ON THE SERIAL NUMBER/RATING PLATE. IF
THE EPSON PRODUCT HAS A PRIMARY AC RATING DIFFERENT FROM AVAILABLE POWER SOURCE, DO NOT CONNECT IT TO THE POWER
SOURCE.
3. ALWAYS VERIFY THAT THE EPSON PRODUCT HAS BEEN DISCONNECTED FROM THE POWER SOURCE BEFORE REMOVING OR REPLACING
PRINTED CIRCUIT BOARDS AND/OR INDIVIDUAL CHIPS.
4. IN ORDER TO PROTECT SENSITIVE MICROPROCESSORS AND CIRCUITRY, USE STATIC DISCHARGE EQUIPMENT, SUCH AS ANTI-STATIC
WRIST STRAPS, WHEN ACCESSING INTERNAL COMPONENTS.
5. REPLACE MALFUNCTIONING COMPONENTS ONLY WITH THOSE MADE BY THE MANUFACTURER; INTRODUCTION OF SECOND-SOURCE ICs
OR OTHER NONAPPROVED COMPONENTS MAY DAMAGE THE PRODUCT AND VOID ANY APPLICABLE EPSON WARRANTY.

1.3 Interfaces
This section is divided into printer and scanner interface specifications. See the
following section for printer interface details or see “Scanner interfaces” on
page 22 for scanner interface details.
1.3.1 Printer interface
PARALLEL
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
PE signal is at high level during paper-out error.
1. Specifications
Transmission mode 8 bit parallel, IEEE-1284 ECP compatibility/nibble
mode
Synchronization Refer to the IEEE-1284 specification
Handshaking Refer to the IEEE-1284 specification
Packet Refer to the IEEE-P1284.4 Standard for Data Delivery
and Logical Channels for IEEE Std. 1284 Interface
(Draft D1.50)

In/Out Description
The strobe pulse. Read-in data is
preformed at the falling edge of this
pulse.
The DATA0 through DATA7 signals
represent data bits 0 to 7, respectively.
Each signal is high when data is logical
1 and low when data is logical 0.
A negative signal that indicates the
printer is ready to accept data
A high signal that indicates the printer
is not ready and cannot receive data
A high signal indicates a paper-out
error
Always at high level when the printer
is on
The falling edge of a negative pulse or
a low signal on this line causes the
printer to initialize. Minimum 50us
pulse necessary.

PREVENTING DATA TRANSFER TIME-OUTS
Generally, hosts abandon data transfer to peripherals when a perip heral is in
the busy state for dozens of seconds continuously. To prevent hosts from
entering this kind of time-out period, the printer slows down the data reception
rate to around several bytes per minute, even if the printer is in the busy state.
This slowdown starts when the remaining open buffer area decreases to
several hundred bytes. The Stylus Scan enters a continuous busy state if the
input buffer becomes full.

INTERFACE SELECTION
The Stylus Scan has two built-in interfaces; the USB and parallel interfaces.
The interface in use is selected automatically.
Automatic selection
When the Stylus Scan is turned on, it initializes and then goes into an idle
state. During this idle period the printer scans the interfaces for incoming
data. The interface that receives data first is selected.
When the host stops transferring data and the printer is in the stand-by
state for a certain amount of time, the printer returns to the idle state. As
long as the host sends data or the printer interface is in the busy state, the
interface selection does not change.
Interface status and selection
When the parallel interface is not selected, the interface goes into the busy
state. When the printer initializes or returns to th e idle state, the parallel
interface goes into the ready state. Be aware that an interrupt signal such
as the -INIT signal only takes effect on the parallel in ter face when the
parallel interface is selected.
IEEE1284.4 PROTOCOL
The packet protocol described by IEEE1284.4 standard allows a device to
carry on multiple exchanges or conversations which contain data and/or
control information with another device at the same time across a single pointto-point link. The protocol is not, however, a device control language. It does
provide basic transport-level flow control and multiplexing services. The
multiplexed logical channels are independent of each other and blocking of one
has no effect on the others. The protocol operates over IEEE1284.
Automatic Selection
An initial state is compatible interface and starts IEEE1284.4
communication when magic strings (1284.4 synchronous commands)
are received.
On
An initial state is IEEE1284.4 communication and data that received it
by the time it is able to take synchronization by magic string (1284.4
synchronous commands) is discarded.
Off
An initial state is compatible interface and never starts IEEE1284.4
communication even if magic strings (1284.4 synchronous commands)
are received.

Requests
The scanner must support almost all standard device requests. The
scanner does not support vendor specific requests.
Some requests and descriptors depend on the configuration (endpoint
number) of each USB device. Therefore this specification recommends the
configuration where Endpoint 1 is Bulk IN endpoint and Endpoint 2 is OUT
endpoint.
