Canon MF6180dw

This product has settings called Special Mode to solve print quality troubles. This function can be executed in the following user mode.

• Menu> Adjust / Maintenance > Special mode

Special mode	Options	Details
Special Mode U	OFF ON	Due to the paper type (for example, heavy paper) or usage conditions (for example, dry conditions), toner smudges and spatters appear on the output. When this occurs, set this setting to <On>. • The print quality may become lower when this setting is enabled, depending on the paper type used (for example, thin paper) or usage conditions (humid conditions).
Special Mode V	OFF Mode 1 Mode 2	If damp paper is used to print, the ejected paper may curl up (the printed side may curl up). In this case, change this setting. the improvement effect is increased in the following order. <Off> -> <Mode 1> -> <Mode 2> (low)                          (high) Paper curls and creases can be minimized by changing the paper type and usage conditions, without needing to change the setting. The more effective the setting becomes, the slower the print speed.
Special Mode X (only for media printing and printing from PS/PCL printer driver) (D1370 only)	OFF Mode 1 Mode 2 Mode 3	Depending on the paper type or the printing environment, liner ink stains may appear on the printed document. If it happens, change the setting of this item. The improvement effect is increased in the following order. <Off> -> <Mode 1> -> <Mode 2> -> <Mode 3> (Effect: Weak)                          (Effect: Strong) If you change the paper type or the printing environment, liner stains may not appear on the printed paper without any setting. The stronger you make the improvement effect, the lower the print density is. It may cause to blur the outlines or enhance the roughness. If you cannot solve the problem even setting this item, try to set the <Special Mode D> to <On>.
Special Mode Z (only for copying)	OFF Mode 1 Mode 2 Mode 3	Due to the paper type or usage conditions, vertical streaks appear on the output. When this occurs, change this setting. <Off> -> <Mode 1> -> <Mode 2> -> <Mode 3> (low)                                                (high) Streaks can be minimized by changing the paper type or usage conditions, without needing to change the setting. The more effective the setting, the lower the density becomes. Additionally, the outline of text and images may be reproduced less clearly, and images may appear slightly jagged. If you cannot solve the problem even setting this item, try to set the <Special Mode D> to <On>.
Special Mode B	OFF Mode 1 Mode 2 Mode 3	Vertical streaks appear on the output after the toner cartridge was replaced recently, or the machine has not printed anything for an extended period of time. When this occurs, change this setting. The effect becomes greater as the number goes up. <Off> -> <Mode 1> -> <Mode 2> -> <Mode 3> (low)                                             (high) If you change the paper type or the printing environment, liner stains may not appear on the printed paper without any setting. If you turn <On> this item, the printing speed will be reduced.
Special Mode C (only for printing received fax and report printing)	OFF ON	Due to the paper type or usage conditions, vertical streaks appear on the output. When this occurs, set one of the following settings to <On>. Noise can also be minimized. Streaks can be minimized by changing the paper type or usage conditions, without needing to change the setting. If you turn <On> this item, the printing speed will be reduced.
Special Mode D	OFF ON
Special Mode G	OFF ON	Depending on the paper type (rough-textured paper, especially 16K size), the output capacity may deteriorate. When this occurs, change the setting to <On>. When <On> is set, the printing speed may decrease during continuous printing. The paper transfer is carried out in the maximum speed, therefore the operation noise will be louder. If you set <On> to any of <Special Mode V>, <Special Mode C>, or <Special Mode D>, this option setting will be invalid.
