TROUBLESHOOTING PROBLEMS RELATED TO SCAN RESULTS Problem The scanned image is clipped. The quality of the scanned image is poor. The scanned image is blank. The scanned image is upside down or on its side. Point to check Is the original scan size setting smaller than the actual original size? Is the original printed matter such as a book or magazine? When scanning a color or grayscale original, is the color mode set to "Mono2"? Is a destination included that has [TIFF-S] selected for the format? Is the original placed face up or face down correctly? Are Internet fax addresses included in the transmission? Solution Set the scan size to the actual original size. If you have intentionally set a smaller size than the actual original size, note carefully the placement position of the selected scan size when placing the original. For example, when scanning an 8-1/2" x 11" (A4) original using a 5-1/2" x 8-1/2" (B5) setting on the document glass, align the original using the document glass scale at the left edge to fit the area you wish to scan into the 5-1/2" x 8-1/2" (B5) scanning area. ☞ 1. BEFORE USING THE MACHINE "PLACING THE ORIGINAL ON THE DOCUMENT GLASS" (page 1-46) Use the following method to reduce the occurrence of vertical patterns (moiré) When the original is printed matter, vertical patterns (moiré) may occur. Touch the [Exposure] key in the base screen to open the exposure setting screen. The [Moiré Reduction] checkbox appears in this screen. This checkbox can be selected to reduce the moiré effect. (only in scan mode and USB memory scan mode) It may also be possible to reduce the moiré effect by changing the resolution setting or shifting the original (or changing its angle) slightly on the document glass. Setting the color mode to "Mono2" replaces the colors in the original with either black or white. This is suitable for text-only documents. To scan a document that includes illustrations or other images, set the color mode to [Grayscale] or [Full Color]. If you wish to send an image scanned at high resolution to scan mode destinations, send the image in a separate transmission. When a broadcast transmission is performed that includes both scan mode destinations and Internet fax destinations that have [TIFF-S] selected for the format, the resolution will remain fixed at [200X200dpi] even if a different resolution setting is selected. Reload the thermal paper correctly and send the fax again. When using the document glass, the original must be placed face down. When using the automatic document feeder, the original must be placed face up. Send the image to the scan mode destinations in a separate transmission. When both scan mode and Internet fax destinations are included in a broadcast transmission, the original transmission orientation of Internet fax takes precedence, and thus the file may not appear in the correct orientation when viewed on a computer. 8-41 Contents
