Resolution guidelines
The table below shows the recommended resolutions in dots
per inch or pixels per inch for the image types and printing
or display methods. You may want to experiment with your
scanner settings, possibly using a cropped version of your
image to save time, until you achieve the desired results.

The resolution that you use to scan an image (input
resolution) does not have to match the dots per inch of your
printer (output resolution). Input and output resolution are
two quite different measurements.

Data format
The data format specifies the number of bits used to
represent the tone of a pixel. The data format can be set in the
range of 1 bit to 8 bits per pixel per color.
Scanning Functions
Scanner settings
As the value increases, more tones and colors can be
captured in the scanned image as shown in the following
table:
Data format
1 bit/pixel/color
2 bits/pixel/color
3 bits/pixel/color
4 bits/pixel/color

Interface error
Initialization
The interface setup is wrong, or the scanner is not properly
connected to the computer.
The scanner can be initialized (returned to a fixed set of
conditions) from hardware or software.
Hardware
Software
initialization
initialization
* When the power is turned on
* Whme scanner parallel interface receives
an INIT signal (pin 31 goes low)
* When the scanner receives a SCSI Reset
signal at the SCSI interface
1 * When the software command ESC Q
(initialize the scanner) is received
* When the SCSI Bus Device Message is received
When the scanner is initialized, the scanner terminates the
scanning operation, and the carriage returns to the home
position (rear of the scanner).
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
One of the following problems occurred:
Ll The fluorescent lamp needs to be replaced.
Ll The transportation lock lever is not released.
Ll The scanner is broken.
Ll There is a problem, such as an open cover, with the
optional transparency unit or the optional automatic
document feeder.
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:
Ll Incorrect setup of the interface
Ll Inappropriate selection of the scanner functions
When this error occurs, check that the transportation lock
lever is released and check any options installed; then push
the RESET button. If the scanner still does not operate
properly, try turning the scanner off and then back on. If the
scanner still does not operate properly, or if this error occurs
repeatedly, consult your dealer.
Ll Incorrect setup of your computer or software
Option error
Ll Incorrect operation of your software.
This indicates a problem such as a paper jam with an
installed option unit.
Also see the documentation that came with your software,
computer, and printer for possible solutions.
When this error occurs, check the option unit and correct the
cause of the trouble.
Indicator lights
If an error occurs, the scanner stops operating and the
READY and ERROR lights show the type of error.

Command error
The scanner received incorrect commands from your
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.
Options
Automatic Document Feeder (B813001)
The automatic document feeder (ADF) option allows you to
stack up to 30 sheets and scan them automatically. This is
especially helpful for optical character recognition (OCR)
scanning. The ADF replaces the scanner cover but still allows
scanning of individual items.
Note:
The ADF (B823011) for the ES-1200C may also be used.
Transparency Unit (B813071)
The transparency unit option allows you to scan slides,
negatives, and transparencies up to 8.5 x 11.7 inches. The
transparency unit replaces the scanner cover but still allows
scanning of individual items.
