Have the peripheral devices that are

Problem Point to check Solution
The image is grainy. Are the printer driver settings
appropriate for the print job?
Check the settings of the printer driver.
When selecting print settings, you can set the print
mode to [Normal], [High Quality]. When you need a very
clear image, select [High Quality].
Windows:
The resolution setting is selected in the [Advanced]
tab of the printer driver properties window.
Macintosh:
Select the resolution in the [Advanced] menu of the
print window. (In Mac OS v10.5, select the resolution
on the [Color] menu in the print window.)
The image is too light
or too dark.
Does the image (particularly a photo)
need correction?
(Windows)
Check the settings of the printer driver.
Brightness and contrast can be corrected by performing
[Color Adjustment] on the [Color] tab of the printer
driver. These settings can be used for simple
corrections when you do not have image editing
software installed on your computer.
Colors are off. Did you perform "Registration
Adjustment"?
Ask your administrator to perform "Registration
Adjustment".
➞ System Settings (Administrator) > "Device Control" >
"Other Settings" > "Registration Adjustment"
If the color tones are off, perform "Auto Color
Calibration". (If the colors are still off after calibration,
repeating calibration may improve the results.)
➞ System Settings (Administrator) > "Printer Settings" >
"Auto Color Calibration"
Text and lines are faint
and difficult to see.
Was color data printed in black and
white?
(Windows)
Check the settings of the printer driver.
When color text and lines are printed in black and white,
they may become faint and difficult to see. To have
color text or lines (areas) that are faint converted to
black, select [Text To Black] or [Vector To Black] on the
[Color] tab of the printer driver. (Raster data such as
bitmap images cannot be adjusted.)
