Cannot scan a document.
1 Is there anything displayed in the LCD?
If nothing is displayed, see the User’s Guide.
2 Is the Alarm light blinking?
If it is blinking, see the User’s Guide.
3 Is the document loaded correctly?
Check that the document is loaded correctly on the platen glass or ADF (→ User’s
Guide).
4 Restart the computer.
5 If using a USB hub or repeater, try connecting the USB cable directly to the computer.
If you can scan documents successfully after connecting the USB cable directly to the computer,
the USB hub or repeater may be broken. Replace if necessary.
6 Are you using a USB 2.0-compatible USB hub?
If you are connecting a USB 2.0-equipeed computer and the printer using a USB 2.0-compatible
USB hub, you may not be able to scan. In this case, connect the USB cable directly to the
computer.
If you want to connect the printer and computer via a USB 2.0-compatible hub, follow the steps
below to modify the INI file. It is recommended that before opening the file in step 1 below, you
make a backup copy of the file in another folder before making any changes to it.
(1) Open the following file in Notepad or another text editor application.
Windows 98/Me:
windows\system\CNCMP50.ini
Windows 2000:
winnt\system32\CNCMP50.ini
Windows XP:
windows\system32\CNCMP50.ini
(2) Below the last line, add the following two lines, then save the file. Take care not to modify any
other parts.

ReadSize=16
7 Is the [Select source] setting in the MP Toolbox, ScanGear MP, or WIA driver set correctly?
Choose between loading the document on the platen glass or ADF.
8 After installing the software, did you install a TWAIN-compatible application?
If this is the case, the TWAIN system file is replaced with something inappropriate and you will be
unable to scan images. If this happens, remove the software and reinstall (→ “Removing and
Reinstalling the software”).
9 Is the machine recognized in the [Scanners and Cameras] Window of [Control Panel]?
Follow this procedure to check if the machine icon is present in [Scanners and Cameras] of the
Control Panel:
1 On the Windows desktop, click [Start], point to [Settings], then click [Control Panel].
(Windows XP: On the desktop, click [Start], then [Control Panel].)
2 Double click [Scanners and Cameras]. (Windows XP: In the [Control Panel] window, click
[Printers and Other Hardware], then [Scanners and Cameras].)
