Epson Macintosh - Manual (Page 55)

See if your Macintosh has enough application memory to run
your software. If you are running other software at the same
time, you may not have enough memory left. See the section on
memory allocation in your Macintosh manual.
The scanner does not start scanning.
See that the
scanner’s READY light
is on.
Make sure the scanner's terminator and SCSI ID are set
correctly.
After clicking the Preview icon, the image does not appear in the
preview window.
Click on the TWAIN preview window.
The scan is not the full width
you
selected in the
preview area.
The EPSON ES-300C and ES-600C scanners restrict the scan
width to 4096 pixels at high resolutions. Choose a lower
resolution for a wider scan.
After scanning and opening several scanned images, your
application software fails and your scanned image is lost.
Save and close the scanned images before scanning a new one.
The size of your image increases after scanning it into your image
editing application.
Your image editing software may be converting the image to
full 24-bit data, which requires more disk space. See your
application software manual for more information.
