These signals represent information

of bits 1 to 8 respectively. Each

signal is at a high level when data is

logical 1 and low when it is logical 0.

10 28 ACKNLG OUT About a 12-microsecond pulse. Low

indicates that data has been received

and that the scanner is ready to

accept more data.

11 29 BUSY OUT When this signal is high, the scanner

cannot receive or send data. The

signal is high:

1) during data entry

2) when the scanner is not ready

3) when the scanner has an error

31 INIT IN When this signal level becomes low,

the scanner is reset to the state

when power is turned on. This level

is usually High. The pulse width

must be more than 50

microseconds at the receiving

terminal.

32 NC Not used

33 GND Twisted-pair return signal ground

3435 NC Not used

36 DIR IN Low indicates the direction is input

Return Pin denotes the twisted-pair return, to be connected at signal ground level.

For interface wiring, be sure to use a twisted-pair cable for each signal, and to

complete the connection on the return side. These cables should be shielded and the

ground connected to the chassis of the host computer and the scanner.

All interface conditions are based on TTL level.

Initialization

The scanner can be initialized (returned to a fixed set of

conditions) in the following ways.

Hardware initialization: When the power is turned on.

When the scanner receives an INIT signal at the parallel interface (pin 31

goes low).

When the scanner receives a SCSI Reset signal at the SCSI interface.

When you push theRESET button.

Software initialization: When the software command ESC@ (initialize the scanner) is received.

When the SCSI Bus Device Message is received.

EPSON ACTIONSCANNER II

ActionScanner II-4 10/95 Scanners

Lights and Buttons

The scanner has three indicator lights and two buttons.

OPERATE light (green) Comes on when the scanner is turned on.

READY light (green)

Comes on when the scanner is ready to scan images. This light

flickers during scanning. When an error occurs, this light and

the ERROR light indicate the type of error.

ERROR light (red)

Indicates when an error occurs. Along with the READY light, it

indicates the type of error.

OPERATE button

Turns the scanner on and off.

RESET button

Resets the scanner after an error occurs. Pressing this button

during scanning stops the scanner and may cause an error in

the scanning software.

Scanner Errors

If an error occurs, the scanner stops operating and the

READY and ERROR lights show the type of error.

Error type READY ERROR

Command error On On

Interface error Off Flashing

Fatal error Flashing Flashing

Command Error

The scanner has received incorrect commands from the

scanning software.

When this error occurs, try to rescan the document. The

scanner returns to normal when it receives correct commands.

Normally you do not need to reset the scanner.

Interface Error

The interface setup is wrong, or the scanner is not properly

connected to the computer.

When this error occurs, check the interface connection. Then

push the RESET button or turn the scanner off and then back

on to reset it.

Fatal Error

This indicates one of the following problems:

One or more fluorescent lamps needs to be replaced.

The transportation screw has not been removed.

The scanner is broken.

Check that the transportation screw has been removed; then

push the RESET button. If the scanner still does not operate

properly, try turning the scanner off, wait 10 seconds, and then

turn it back on. If the scanner still does not operate properly, or

if this error occurs repeatedly, consult your dealer.

Cleaning the Scanner

To keep the scanner operating at its best, clean it periodically.

Before cleaning, unplug the power cable.

Clean the outer case with mild detergent dissolved in water.

If the document glass gets dirty, clean it with a soft dry cloth. If

the glass is stained with grease or other hard-to-remove

material, use a small amount of glass cleaner on a soft cloth to

remove it. Wipe off any remaining liquid with a dry cloth.

Be sure there is no dust on the document glass. Dust can cause

white spots in the scanned image.

Caution: Do not scratch or damage the document glass, and do not use a hard or abrasive brush to clean it. A damaged glass surface can decrease the scanning quality.

Never use alcohol, thinner, or corrosive solvent to clean the

scanner. These chemicals can damage the scanner components

as well as the case.

Scanners 10/95 ActionScanner II-5

Be careful not to spill liquid into the scanner mechanism or

electronic components. This could permanently damage the

mechanism and circuitry.

Do not spray lubricants inside the scanner.

Never open the scanner case.

Replacing the Fluorescent Lamps

The luminosity of the fluorescent lamps declines over time. If the

lamps break or become too dim to operate normally, the

scanner stops working and both the READY light and the

ERROR light flash. When this happens, the lamp assembly

must be replaced. For details, contact your dealer.

Caution: Users should never open the scanner case.
