| If you use this mode, printing quality may become lower depending on the paper type (especially when using thin paper) or environment (especially in wet environments).
Special Mode V | Off, Mode 1, Mode 2, Mode 3 | Depending on the paper type or environment, vertical streaks may appear on printed paper. In this case, change this setting. The effect becomes greater as the number goes up.

| This setting is available when
| <Paper Size> is set to <B5>, <A5>, <STMT>, or <EXEC> <Paper Type> is set to <Plain (60-90 g/m2)>, <Plain L (60-90 g/m2)>, <Recycled>, <Color>, <Rough 1 (60-90 g/m2)>, or <Envelope>
| As you select an option that has stronger effect, printing speed becomes slower.
Special Mode Z | Copy: Off, Mode 1, Mode 2, Mode 3, Mode 4 Fax: Off, Mode 1, Mode 2, Mode 3, Mode 4 | Depending on the paper type or environment, vertical streaks may appear on printed paper.

| (low) |  | (high)
| Change of paper type or environment may reduce the streaks, even without changing the setting.
| As you select an option that has stronger effect, printing density becomes lower. Outlines of printed text or images may be less clear, or images may be slightly jagged.
Special Mode B | Off, Mode 1, Mode 2, Mode 3 | After replacing the toner cartridge or when using a toner cartridge after a long time, vertical streaks may appear on printed documents. In this case, change this setting. The level of improvement according to the setting option is as following.

Special Mode J | Off, On | Printed paper may be spotted when printing thin lines or light images. In this case, set this setting to <On>.
| If you use this mode, the following problems may occur.
| The output is less fine. Toner smears even on unnecessary parts. Toner consumption increases.
Special Mode K | Off, On | Depending on the environment (especially in low temperature environments), toner may not be fixed sufficiently and output may be less clear. In this case, set this setting to <On>.
| Change of environment may improve the toner fixation, even without changing the setting.
