TROUBLESHOOTING Problem The quality of the scanned image is poor. Point to check 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? The scanned image is blank. Is the original placed face up or face down correctly? The scanned image is upside down or on its side. Are Internet fax addresses included in the transmission? The [COLOR START] key indicator is not lit. Are Internet fax or fax destinations included? JPEG was selected for the file type but the file was created as a TIFF file. Did you press the [BLACK & WHITE START] key to begin scanning? Solution 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 originals; however, for originals that contain illustrations, it is best to use the [BLACK & WHITE START] key with the color mode set to [Grayscale], or set the color mode of the [COLOR START] key to [Full Color] or [Auto]-[Grayscale] and then scan. 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. Use the [BLACK & WHITE START] key. If Internet fax or fax destinations are included in the destinations, only the [BLACK & WHITE START] key can be used. Change the color mode to [Full Color] and then press the [COLOR START] key. When [JPEG] is selected for the file type and the image is scanned in Mono 2, the file will be created as a TIFF file. 8-31 Contents
