Auto Paper Selection Setting The paper types* that the Auto Paper Selection function will select can be specified. Select one of the following settings: • Plain Paper • Plain and Recycle Paper • Recycle Paper The Auto Paper Selection function will not select any paper types other than the paper types specified with this setting. * The paper type set for each paper tray using "Paper Tray Settings" (page 6-13) in the system settings (general). Detect Standard in Auto Color Mode When the color mode is set to auto in copy mode, the discrimination point for detecting whether originals are color or black and white can be set to one of 5 levels. To make it easier to detect a black and white original, adjust the setting toward [Black & White]. To make it easier to detect a color original, adjust the setting toward [Color]. Fusing Control Settings These are used to control the toner fusing temperature according to the weight of the paper. These settings apply to plain paper, recycled paper, punched paper, pre-printed paper, letterhead paper, colored paper, and user type paper. You can select "16 to 23 lbs." or "23+ to 28 lbs." ("60g/m2 to 89g/m2" or "90g/m2 to 105g/m2"). • Be sure to use only paper that is in the same weight range as the weight range set here. Do not mix plain or other paper that is outside the range with the paper in the tray. • When settings are changed, the changes will take effect after the machine is restarted. To restart the machine see "TURNING THE POWER ON AND OFF" (page 1-14) in "1. BEFORE USING THE MACHINE ". SYSTEM SETTINGS WEB PAGE (ADMINISTRATOR) Interval of Image Quality Adjustment The machine automatically performs Image Quality Adjustment at regular intervals in order to prevent changes of color after repeated color printing. This setting is used to select the interval of Image Quality Adjustment. The interval becomes shorter and Image Quality Adjustment is performed more frequently in the following order: Setting 1 (Long), Setting 2, Setting 3, Setting 4, Setting 5 (Short) Guidelines for selection If you print mostly business documents in black and white, Setting 2 (factory default setting) or Setting 1 (Long) is recommended. If you often print photos, Setting 3 or higher is recommended. • When Setting 3 or higher is selected, more toner is consumed than usual, and when a job is being printed, printing may take place more slowly. • Image Quality Adjustment can also be performed whenever you notice that the color has changed. See "Image Quality Adjustment" (page 6-10). 6-73 Contents
