“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

ZiT

signal at the parallel

interface (pin 31 goes low).

When the scanner receives a SCSI Reset signal at the SCSI

interface.

Software initialization:

When the software command ESC @(initialize the

scanner) is received.

When the SCSI Bus Device Message is received.

Problems and Solutions

The problems you may have while using the scanner often

involve the operation of your software and computer.

Problems fall in the following major categories:

Incorrect setup of the interface

Inappropriate selection of the

scaflner

functions

Incorrect setup of your computer or software

Incorrect operation of your software

Incorrect loading of documents.

Also see the documentation that came with your software

and computer for possible solutions.

Indicator lights

If an error occurs, the scanner stops operating and the

Ready

type

of error.

Command error

The scanner has received incorrect commands from your

scanning software. When this error occurs, retry the scanning

operation. The scanner returns to normal operation when it

receives correct commands. Normally you do not need to

reset the scanner, which is done by turning the scanner off

and then on.

caution:

Whenever you

turn

ofthe

scanner, wait at least 20 seconds

befoe

turning it back on. Rapidly turning it on and

@can

damage the scanner.

Interface error

The scanner may not be properly connected to the computer.

Check the interface

co~eCtions.

Then turn the

scanner

off

and back on to reset it.

The interrupt settings or the port addresses for the interface

board may not be set correctly or may conflict with

other

installed expansion boards.

Fatal error

This error indicates one of the following problems:

The fluorescent lamp needs to be replaced.

Paper is jammed in the document feeder.

There is no document

the document feeder or the

document was not loaded correctly.

The software may not be set up properly.

Check to see if the fluorescent lamp is on. If not, the lamp

may need to be replaced. Contact your dealer or a.qualified

service person for assistance.

Turn off the scanner and remove any paper that may be

jammed in the document feeder. If the scanner still does not

operate properly, or if this error occurs repeatedly, consult

your dealer.

Make sure the document is loaded correctly in the document

feeder, and then resume scanning.

Check to see that your software is installed correctly. Also

make sure you have selected the correct device driver for the

scanner. See your software manual for details.
