<Special Processing>

If the print results on special types of paper are not satisfactory, the following settings may improve the quality of the printouts.
<Special Paper Processing>
When printing on the back side of printed paper, rough paper, or envelopes, the print results may be improved by adjusting the following settings.
<Manual Back Side Print (2-Sided Only)>
If printouts on the back side of printed paper are too light, select <On>. You can specify this setting separately for each paper source.
<Multi-Purpose Tray>
<Off>
<On>
 
<Drawer 1>
<Off>
<On>
If you set to <On>, image quality may be affected or a paper jam may occur when a certain length of time elapses after printing on the front side or depending on the ambient humidity.
<Rough Surface Paper Mode>
When printing on rough paper, especially when color images are printed too light, select <On>. You can specify the settings separately for each paper source.
<Multi-Purpose Tray>
<Off>
<On>
 
<Drawer 1>
<Off>
<On>
If you set to <On>, the printing speed may be slower or image quality may be affected.
<Env. Flap Closing Prevention>
If envelope flaps cling to the envelope bodies when printing, select <On>.
<Off>
<On>
If you set to <On>, toner may not be fixed sufficiently, resulting in faded printouts.
<Paper Wrinkle Correction>
Printouts may wrinkle depending on the paper to use. In this case, setting this item may solve the problem. The improvement effect is stronger with <Mode 2> than with <Mode 1>.
<Off>
<Mode 1>
<Mode 2>
<Mode 1> is effective for envelopes, and <Mode 2>, for envelopes and thin paper.
When <Mode 1> or <Mode 2> is specified, printed images may be blurry.
<Paper Curl Correction>
If the printed paper curls, set this item. The improvement effect is stronger with <Mode 2> than with <Mode 1>. First try with <Mode 1>.
<Off>
<Mode 1>
<Mode 2>
Setting a greater improvement effect may result in faded printouts or slower printing speed.
<Reduce Ppr. Sticking at Output> *
When performing 2-sided printing in color, paper may stick together at the output. Setting this item will slow down the printing speed of prints that may easily stick together, to reduce sticking.
<Off>
<Mode 1>
<Mode 2>
The improvement effect is stronger with <Mode 2> than with <Mode 1>.
<High Humidity Mode>
Print density may be uneven when the machine is used in an environment with high humidity. In this case, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On> and use the machine in an environment with low humidity, printed images and text may be blurry.
<Low Humidity Mode>
When using the machine in an environment with low humidity, printed images and text may be blurry. In this case, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, print density may be lower or uneven when the machine is used in an environment with high humidity.
<Reduce Ghosting 2>
If continuous printing involves generation of ghost images, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, print density may be uneven.
<Rdc Condens. (Consec 2-Sd Prt)> *
If the printed images are faint due to moisture condensation when performing 2-sided printing, setting to other than <Off> may solve the problem.
<Off>
<On>
If you set to <On>, the print may be faded or the printing speed may be slower.
<Correct Void>
If printing on thin paper produces void in the leading edge of the paper, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, printouts may be faded.
<Reduce Waterdrop Pattern>
If print density is uneven in a way that the print looks like a water drops pattern, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, print quality may be affected.
<Prevent Fogging>
If white areas are lightly colored, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, print density may be lighter.
<Correct Color Mismatch>
If color mismatch occurs, setting to <On> may solve the problem.
<Off>
<On>

Toner may peel off the printed page depending on the paper type or the environmental conditions. In this case, setting this item may solve the problem.
<Off>
<On>
If you set to <On>, ghost images may appear in blank areas.
<Auto Detect B&W/Color Orig.>
When black and white print data is mixed with color data, specify whether to prioritize the print speed or to reduce the toner usage of the cyan, magenta, and yellow toner cartridges when printing data.
<Mode 1>
<Mode 2>
<Rdc. Faint Print After Rplc. Cart.>
Printouts may be faded immediately after replacement of toner cartridges with new ones. In this case, setting this item to <On> may solve the problem.
<Off>
<On>
If you set to <On>, the setting will become effective with next replacement of toner cartridges.
Immediately after cartridge replacement, a certain amount of time is required for toner to be evenly distributed inside the cartridge.
<Prevent Black & White Printing Noise>
The machine may make an unusual noise during continuous black and white printing. In this case, setting this item to <On> may solve the problem.
<Off>
