to use and where to load each profile.) KONICA MINOLTA recommends that
you use these specialized host profiles for CMYK print jobs to manage the
amount of toner put on the page. They are useful when working with Microsoft
ICM2 for Windows, Apple ColorSync, CorelDRAW, Kodak KCMS, Adobe
PageMaker, Adobe Illustrator, Adobe Photoshop, and other applications.
Gray Treatment
Process gray can be turned on or off for each element of the job:
Color printing/Black & Gray—prints all 100% black and intermediate grays
with black toner only.
Color printing/Composite Black—prints 100% black and intermediate
grays with a composite of all four toners.
Troubleshooting Color Problems
The magicolor 7300 color matching system is optimized for the sRGB
Standard, which is the standard used with many common applications such
as Microsoft Office. In most cases, you do not need to make any adjustments
to the default color settings to achieve the best results.
If you have trouble with color, however, there are several things to check.
1
Mechanical Problems. Print quality problems that are caused by
mechanical problems are usually drastic—colors that change from page
to page; colors that are off-register; colors that aren’t anything like you
expect.
Are all four toner cartridges installed properly?
Do all four toner cartridges have toner?
Are the print units installed properly?
Are the printer doors closed?
Instructions for checking all these mechanical issues are included in
chapter 10, “Troubleshooting.”

Resolution. If images look grainy or if your page is printed with black
toner only, the Color Options may be set for Black & White printing or the
resolution may be set wrong.
If Color Options is set to Black & White, all text and graphics print in
100% black.
If the resolution is set to Standard, text prints well, but images may
look grainy or unclear. It’s a good choice for text documents.
If the resolution is set to High, images are sharp and clear. Printing
takes somewhat longer at High resolution, but it’s the best choice for
the delivery copy of a document containing images.
