Scanning Problems
See the following sections.
Cannot scan a document.
Refer to the following section:
The scan is too slow.
|
When connecting the wireless LAN router or access point, check the following.
The distance between wireless LAN router and access points is within 164' (50 m) (may vary on the communication speed or environmental condition).
There are no obstacles between the wireless LAN router or access point and the machine.
There are no microwave ovens or refrigerators near the installation area.
When multiple networks are used, to avoid interference between the channels, each network will be set to a channel that is as far apart from other network channels as possible such as Ch.1, Ch.6, and Ch.11.
If the scan is still slow, turn OFF the machine and wait for at least 10 seconds before turning it back ON.
|
Cannot scan multiple documents to create a combined multi-page PDF file.
|
Start ScanGear MF, access the Preferences dialog box, and clear the check box next to [Automatically Quit ScanGear after Scanning] before you perform a scan. When this check box is selected, you can only perform a scan from the platen glass.
|
<An error has occured.> appears on the operation panel. (When scanning from the operation panel)
|
Close the MF Toolbox and scan the document again.
|
During scanning, a computer connected to the machine freezes or is disconnected.
|
Quit all running applications to increase the memory usage.
|
|
Make sure that the machine has sufficient free hard disk space when scanning documents at a high resolution. To scan an A4-sized document at a resolution of 600 dpi in full color, for example, a minimum of 300 MB of free space is required.
|
|
If an error occurs while scanning a specific image for Photoshop, access the [Edit] menu, select [Preferences], and click [Memory & Image Cache]. Set [Memory Usage] somewhere between 50 and 60 %.
|
|
The scanner driver may not be installed properly. Uninstall the software and install it again.
|
In the event that applications installed from the User Software CD-ROM that comes with the machine are not properly registered in the MF Toolbox.
|
Applications are automatically registered to the MF Toolbox once they have been installed. They are not, however, if installed while the MF Toolbox is open. To access these applications from the toolbox, you need to manually register them to the toolbox.
|
A different application opens when you want to scan a document.
|
Register the appropriate application in the MF Toolbox.
|
Scanned images are spotted or distorted.
|
Clean the platen glass and feeder's scanning area.
|
|
Scanned images cannot be displayed correctly if displayed smaller than the actual size, depending on the application. Scale the images to 100 %.
|
|
Set the display colors to "High Color (16-bit or 24-bit)" or higher in [Display Properties].
|
A scanned image is displayed larger (or smaller) than its actual size on the computer screen.
|
Try one of the following to set the appropriate resolution.
Enlarge or reduce the image size in the application that you are using. In an application such as MS Paint or Imaging, an image may be displayed larger than its actual size and cannot be scaled down.
To solve this problem, scan the image again at a different resolution. If scanned at a higher resolution, the image is displayed larger than its actual size, and vice versa.
|
Cannot scan highlighting marks.
|
Start the ScanGear MF, access [Advanced Mode], and set [Color Correction] to [Color Matching].
