Scanning very slowly
x
ý

Adding more memory to the computer can dramatically improve scanning speed,
especially for higher resolution color images. If there is a lot of disk activity when
scanning is the only application running on the computer, this is a good indication
that additional memory is needed.

ý
Communication speed becomes slow in scan mode because a lot of memory is
required to analyze and reproduce the scan image. It is recommended that you set

this mode is not supported by A900.). For details on how to set the mode in your
BIOS, refer to the documentation that came with your computer.
