1. Use in High-Safety Applications
---------------------------------------------------

This product has been designed and manufactured on the assumption that it will be used in office, personal, domestic, regular industrial, and general-purpose applications.
It has not been designed and manufactured for use in applications (simply called "high-safety applications" from here on) that directly involve danger to life and health when a high degree of safety is required, for example, in the control of nuclear reactions at nuclear power facilities, automatic flight control of aircraft, air traffic control, operation control in mass-transport systems, medical equipment for sustaining life, and missile firing control in weapons systems, and when provisionally the safety in question is not ensured.
The user should use this product with adopting measures for ensuring safety in such high-safety applications. PFU Limited assumes no liability whatsoever for damages arising from use of this product by the user in high-safety applications, and for any claims or compensation for damages by the user or a third party.

4. Notes on Scanning
---------------------------------------------------

- Do not let your computer enter standby mode during scanning. Otherwise, scanning may fail due to the "Error during device I/O" error and so on.

- Do not unplug the power cable or interface cable during scanning. Otherwise, scanning may fail due to the "Error during device I/O" error and so on. In that case, connect the USB cable again and power on the scanner to make the computer recognize the scanner.

- Do not log off your computer during scanning. Otherwise, scanning may fail due to the "Error during device I/O" error and so on.

- Do not stop an application with the job control function ("Ctrl+z") during scanning.
  When you resume the application, it may not operate properly, outputting an error such as "Error during drive I/O". In such a case, exit the application.

5. Notes on Scan Settings
---------------------------------------------------

Notes on the following scanning options are described.

(1) autofeed
  A preceding scan is performed by using the cache memory in the scanner. Because all sheets that are loaded in the feeder are fed, if an application stops the scanning process along the way, the scanned images that remain in the cache memory are discarded. By default, this option is set to "yes". To scan one sheet per scan, set this option to "no".

(2) page-auto
  - When the crop function is used, the function to specify the scanning area cannot be used.
    Options -l, -t, -x, -y are ignored.
  - When paper larger than the specified paper size is scanned, the crop function is not available.

(3) scanning area(-x, -y)
  - If you specify a size that is larger than an A4 size paper for "page-width" and "page-height" when the cropping function is not used, specify the same value for -x and -y.
    Otherwise, the "Document feeder jammed" error may occur.
