Messages Displayed on the Client Computer When You Use the Scanner Function

This section describes likely causes of and possible solutions for the main error messages displayed on the client computer when you use the TWAIN driver. If a message not described here appears, follow the instruction.

Message	Cause	Solution
`“Any of Login User Name, Login Password or Driver Encryption Key is incorrect.”`	The entered login user name, password, or driver encryption key was invalid.	Check your login user name, login password, or driver encryption key, and then enter them correctly. For details about login user name, login password, and driver encryption key, see "Encrypting Transmitted Passwords", Security.
`“Authentication succeeded. However, the access privileges for scanner function has been denied.”`	The logged in user name does not have permissions for scanner function.	For details about how to set permissions, see "Limiting Available Functions", Security.
`“Cannot add any more scanning mode.”`	The maximum number of registrable scan modes has been exceeded.	The maximum number of modes that can be stored is 100. Delete unneeded modes.
`“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 exposure glass cover or the Auto Document Feeder (ADF) triggers the automatic original size detection process. Lift the exposure glass cover or the ADF 30 degrees or more.
`“Cannot specify any more scanning area.”`	The maximum number of registrable scan modes 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 the 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.
`“Error has occurred in the scanner driver.”`	An error has occurred in the driver.	Check whether the network cable is connected correctly to the client computer. Check whether the Ethernet board of the client computer is recognized correctly by Windows. Check whether the client computer can use the TCP/IP protocol.
`“Error has occurred in the scanner.”`	The application-specified scan conditions have exceeded the setting range of the machine.	Check whether the scanning settings made with the application exceed the setting range of the machine.
`“Fatal error has occurred in the scanner.”`	An unrecoverable machine error has occurred.	An unrecoverable machine error has occurred. Contact your service representative.
`“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: Scanning cannot be performed if large values are set for brightness when halftone or high resolution is used. 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.
`“Invalid Winsock version. Please use version 1.1 or higher.”`	You are using an invalid version of Winsock.	Install the operating system of the computer or copy Winsock from the operating system CD-ROM.
`“No response from the scanner.”`	The machine or client computer is not connected to the network correctly.	Check whether the machine or client computer is connected to the network correctly. Disable the client computer's own firewall. For details about firewall, see Windows Help.
`“No response from the scanner.”`	The network is crowded.	Wait for a while, and then connect to the network again.
`“Scanner is in use for other function. Please wait.”`	A function of the machine other than the scanner function is being used such as the copier function.	Wait for a while, and then connect to the network again. Cancel the job that is being processed. Press [Stop]. Follow the instructions in the message that appears and exit the function that is running.
`“Scanner is not available on the specified device.”`	The TWAIN scanner function cannot be used on this machine.	Contact your service representative.
`“Scanner is not ready. Check the scanner and the options.”`	The ADF cover is open.	Check whether the ADF cover is closed.
`“The name is already in use. Check the registered names.”`	You tried to register a name that is already in use.	Use another name.

When there is a problem connecting to the scanner
Message	Cause	Solution
`“Cannot connect to the scanner. Check the network Access Mask settings in User Tools.”`	An access mask is set.	For details about an access mask, contact your administrator.
`“Cannot find "XXX" scanner used for the previous scan. "YYY" will be used instead.”` ("XXX" and "YYY" indicate scanner names.)	The main power of the previously used scanner is not set to "On".	Check whether the main power 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", Settings. Select the scanner used for the previous scan.
`“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.
`“Scanner is not available. Check the scanner connection status.”`	The machine's power is off.	Turn on the power.
`“Scanner is not available. Check the scanner connection status.”`	The machine is not connected to the network correctly.	Check whether the machine is connected to the network correctly. Cancel the personal firewall function 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", Settings.
`“Scanner is not available. Check the scanner connection status.”`	Network communication is not available because the machine's IP address could not be obtained from the host name. If only "IPv6" is set to [Active], the IPv6 address might not be obtained.	Check whether the machine's host name is specified in the Network Connection Tool. For the WIA driver, check the [Network Connection] tab in the properties. Use Web Image Monitor to set "LLMNR" of "IPv6" to [Active]. (Web Image Monitor is a management tool installed on this machine to monitor this machine or configure settings for this machine by using a web browser.)
