<Adjust Image Quality>

This section describes how to adjust image quality for printing.

<Full Calibration>

<Set>

Use this function to adjust the print density to obtain the optimal print results.

<Settings for Auto Full Calibration>

<Set>

You can set the frequency for automatically performing adjustment (calibration) in accordance with the usage condition of the machine or changes in the environmental conditions. Automatically Adjusting the Density

<Adjust Print Position>

<Set>

You can adjust the print position when printing is lopsided or protruding from the print range. Adjusting the Print Position

<Correct High Temp./High Humidity Void>

<Set>

If printed images are left white when printing in environments with high temperature and humidity, setting this to <On> may solve the problem.


When this is set to <On>, drum cleaning is performed periodically.

<Waterdrop Pattern Prevention Mode>

<Set>

If streaks or spots like scattered water droplets appear on printed images, setting this to <On> may solve the problem.


If you set <Waterdrop Pattern Prevention Mode>, the printing speed for the first sheet becomes slower.

<Reduce Waterdrop Pattern>

<Set>

If some parts of printed images are left white, setting this to <On> may solve the problem.


If you select <On>, the print quality may be affected.

<Correct Background Density>

<Set>

Set this item if there are light colors or dirt in the background.

<Reduce Ghosting 3>

<Set>

If afterimages appear on areas that are not printed, setting this to <On> may solve the problem.


Setting to <On> may result in uneven print.

<Reduce Ghosting 4>

<Set>

If afterimages appear when executing a large amount of printing at one time, setting this to <On> may solve the problem.

<Reduce Ghosting 5>

<Set>

If afterimages appear on areas that are not printed, setting this to <On> may solve the problem.

<Reduce Ghosting 6>

<Set>

If afterimages appear in an environment with high or low humidity, setting this to <On> may solve the problem.

<Reduce Stains on Last Page (2-Sided)>

<Set>

If the back side of the last sheet of paper printed is dirty when performing two-sided printing, setting this to <On> may solve the problem.

<Correct Void for Consecutive Printing>

<Set>

If streaks appear in the printed images when performing continuous printing, setting this to <On> may solve the problem.

<Improve Fixing Area Conveyance (2-Sided)>

<Set>

If paper jams occur around the fixing assembly when performing two-sided printing, setting this to <On> may solve the problem.

<Curl Prevention Mode>

<Set>

You can set <Curl Prevention Mode> to reduce curling on the end of paper due to the heat and pressure of the fixing assembly during printing.


If this setting is set to <On>, it may affect the printing quality. If setting <Mode 1> to <On> does not reduce curling, set <Mode 2> to <On>. If setting both <Mode 1> and <Mode 2> does not reduce curling, set <Mode 1> and <Mode 2> to <Off> and set <Switch Paper Feed Method> to <Print Side Priority>.

<White Streak Prevention Mode>

<Set>

If white streaks appear in the printed images, setting this to <On> may solve the problem.


If you select <On>, ghost images may appear.

<Reduce Drum Streak>

<Set>

If the toner of printed images peels off in stripes, setting this to <On> may solve the problem.

<Adjust Paper Separation in Transfer Area>

<Set>

If paper jams occur around the ITB unit, setting this to <On> may solve the problem.

<Correct Plain Paper Color 2>

<Set>

If uneven glossiness occurs on the printed paper, setting this to <On> may solve the problem.

<Envelope Sealing Prevention Mode>

<Set>

If the output paper sticks together, setting this to <On> may solve the problem.


If this setting is set to <On>, the quality of the image may be adversely affected.

<Special Mode for Coated Paper>

<Set>

If some parts of printed images are faint, setting this to <On> may solve the problem.

<Improve Prod. for Specified Paper Width>

<Set>

When printing on a large amount of A4 and A5 paper, this mode may improve productivity.

<Improve Prod. When Diff. Ppr. Sizes Used>

<Set>

When repeating jobs that combine wide paper and narrow paper, setting this mode may improve productivity.


Setting this mode may reduce the print quality. If the paper type of the job is plain paper, set <Mode 1>. If the paper type of the job is plain paper or heavy paper, set <Mode 2>.
