➤Solution 1: A scan cannot be performed if the scan area is set too small (less than 64 x 64 pixels). Increase the size of the scan area

➤Solution 2: A scan cannot be performed unless a scan area is specified. Specify a scan area

➤Solution 3: A scan cannot be performed if the required memory is larger than the free memory. Change the resolution (➜ p. 19) or scan area

(➜ p. 30) until the required memory is lower

Problem: The “Insufficient Memory” error message appears when scanning

➤Solution 1: Select the smallest possible area and rescan

➤Solution 2: Lower the resolution and magnification settings for the output device to the lowest possible values (➜ p. 19)

➤Solution 3: Rescan after closing all the application programs other than the one used to start Plug-in Module CS-U

➤Solution 4: Rescan after you have restarted the application program used to start Plug-in Module CS-U

➤Solution 5: Quit the application program used to start Plug-in Module CS-U and increase the memory allocated to it. Click the application program icon once. Then open the [File] menu, choose [Get Info], and choose [Memory] from the submenu. Increase the memory in the Preferred Size box to at least 16,000 K.

➤ Solution 6: Increase the amount of RAM as required
