`“Cannot detect the paper size of the original. Specify the scanning size.”` | The set original was misaligned. | Place the original correctly. Specify the scan size. When placing an original directly on the exposure glass, the lifting/lowering action of the ADF triggers the automatic original size detection process. Lift the ADF by 30 degrees or more.
`“Cannot find "XXX" scanner used for the previous scan. "YYY" will be used instead.”` ("XXX" and "YYY" indicate scanner names.) | The main power switch of the previously used scanner is not set to "On". | Check whether the main power switch of the scanner used for the previous scan is turned on.
`“Cannot find "XXX" scanner used for the previous scan. "YYY" will be used instead.”` ("XXX" and "YYY" indicate scanner names.) | The machine is not connected to the network correctly. | Check that the previously used scanner is connected to the network correctly. Cancel the personal firewall of the client computer. For details about firewall, see Windows Help. Use an application such as telnet to make sure SNMPv1 or SNMPv2 is set as the machine's protocol. For details about how to check this, see "Remote Maintenance Using telnet", Connecting the Machine/ System Settings. Select the scanner used for the previous scan.
`“Cannot specify any more scanning area.”` | The maximum number of registerable scan areas has been exceeded. | The maximum number of scanning areas that can be stored is 100. Delete unneeded scanning areas.
`“Clear Misfeed(s) in ADF.”` | A paper misfeed has occurred inside the ADF. | Remove jammed originals, and then insert them again. For details about jammed paper, see Removing Jammed Paper. When a misfeed occurs, replace the jammed originals. Check whether the originals are suitable to be scanned by the machine.
`“Communication error has occurred on the network.”` | A communication error has occurred on the network. | Check whether the client computer can use the TCP/IP protocol.

`“Insufficient memory. Close all other applications, then restart scanning.”` | Memory is insufficient. | Close all the unnecessary applications running on the client computer. Uninstall the TWAIN driver, and then reinstall it after restarting the computer.
`“Insufficient memory. Reduce the scanning area.”` | Scanner memory is insufficient. | Reset the scan size. Lower the resolution. Set with no compression. For details about the settings, see TWAIN driver Help. The problem may be due to the following cause: Scanning cannot be performed if large values are set for brightness when using halftone or high resolution. For details about the relationship between scan settings, see "Relationship between Resolution and Scan Size", Scan. If a misfeed occurs, you might not scan an original. Remove the misfeed, and then scan the original again.
