PRECAUTIONS

There are caut io nary notes throughout the text to help you avoid personal injury or equipment damage.

W ARNING

Signals a precaution which, if ignored, could result in serious or fatal personal injury. Great caution should be exercised in performing procedures preceded by a WARNING heading.

Always observe the measures listed below when performing repair or maintenance procedures.

CAUTION

Signals a precaution which, if ignored, could result in damage to equipment.

WARNING

1. Always disconnect the product from both the power source and host computer before performing any maintenance or repair procedure.

2. No work should be performed on the unit by persons unfamiliar with basic safety measures dictated for all electronics technicians in their line of work.

3. In performing testing described in 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 the power supply and other electronic components.

CAUTION

1. Repairs on E PSON products should be performed only by an EPSON-certified repair technician.

2. Make certain that the source voltage is the same as the rated voltage listed on the serial number/rating plate. If the EPSON product has a primary AC rating different from the 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 befor e rem o ving or replacing printed circuit boards and/or individual chips.

4. 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 components recommended by the manufacturer; introduction of second-source ICs or other nonapproved components may damage the product and void any applicable EPSON warranty.

1.5 Interfaces

This section is divided into printer and scanner interface specifications. See the following section for printer interface details or see “Scanner interfaces” on pag e22 for scanner interface details.

1.5.1 Printer Interface

PARALLEL

BUSY signal is set h i g h b e fore setting either -ERROR low or P E hig h , and held high until all these signals return to th eir 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. Specification

4. Extensibility Request:

The printer responds affirmatively when the extensibility request values are 00H or 04H, which mean

00H Request nibble mode reverse channel transfer

04H Request Device ID;

Return data using nibble mode reverse channel transfer

Device ID:

The printer sends the following device ID string when requested.

PREVENTING DATA TRANSFER TIME-OUT OF HOSTS

Generally, hosts abandon data transfer to peripherals when a peripheral is continuously in the busy state for dozens of seconds. 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 the idle state, the parallel interface goes into the ready state. Be aware that an interrupt signal such as the -INIT sig nal only takes affect on the parallel interface 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 point-to-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 communi c ation and data that received it by the time it is able to take synchronization by magic string (1284.4 synchronous comm ands) is d i s carded.

Off An initial state is compatible interface and never starts IEEE1284.4 communication even if magic strin g s (1284.4 synchronous commands) are received .

low-ink state and continues printing. When the cartridge is completely empty, the printer indicates an ink-out error and stops printing.

If the printer f ails t o prop erly l oad paper , it indicates a paper-out error.

If the printer fails to prope rly eject pap er, it indicates a paper jam.

If the printer detects that one of the ink cartridges i s not installe d, it indicates a no-ink-cartridge error.

When the total amount of waste ink reaches the limit, the printer indicates a maintenance request and stops printing.

Install a new ink cartridge.

Load paper and press the Load/Eject button.

Press the Load/Eject button. If this does not clear the error, remove the paper by hand.

Install a new ink cartridge.

Replace the waste ink pads and reset the waste ink counter with the adjustment program. See Chapter 5 for details.

Turn off the Stylus

Fatal error

A carriage control or CG access error has occurred.

Scan and turn it back on. If the error does not clear, service.

NOTE: Do not re-install used ink cartridges. Doing so confuses the

ink-level detection function and may cause a serious problem in the printhead.

1.9 Options

The optional Auto Document Feeder and optional Transparency Unit designed for use with the GT-7000 scanner may also be used with the EPSON Stylus Scan 2500 under the following restrictions.

1.9.1 Local Copy

ADF

If a document is loaded in the ADF tray, the Stylus Scan loads and scans that document. If a document remains on the document glass, a copy is not produced normally. Even if multiple copies are selected, the Stylus Scan ignores this setting and produces only one copy per document sheet.

TPU

The TPU cannot be used in Local Copy mode. The Stylus Scan ignores the TPU in this mode.

1.9.2 Scanning

ADF

Same as the GT-7000.

TPU

If the Stylus Scan receives transparency scanning commands, it will turn on the TPU lamp and scan the transparency after the warm-up period. The Stylus Scan ignores the ADF in this mode. After scanning, the TPU lamp remains on until the TPU is turned off or until the Stylus Scan receives reflective document scanning commands.

If the Stylus Scan receives reflective document scanning commands, it will scan the document normally.
