Printing Problems
THE IMAGE IS TOO LIGHT OR TOO DARK
Check Solution
Is the overall print density too light? ■ Use the setting below to change the overall print density. 
Select "Setting mode (Web version)" - [System Settings] → [Image Quality 
Adjustment] → [Print Image Quality] → [Quick Image Quality Adjustment]. Set 
default setting [2] to [1 (Smooth)] to decrease the overall density, or [3 (Sharp)] to 
increase the overall density. 
This setting can be set separately for color mode and monochrome mode.
Does the image (particularly a photo) 
need correction?
(Windows)
■ Check the settings of the printer driver. 
Correct brightness and contrast with [Image Quality] on the [Color Adjustment] 
tab of the printer driver.  Use these settings to make simple corrections in a case 
such as when image editing software is not installed on your computer. 
COLORS ARE OFF
Check Solution
Did you perform "Registration 
Adjustment"?
■ Ask your administrator to perform "Registration Adjustment".

 [Registration Adjustment] .
 
If the color tones are off, perform [Auto Color Calibration (for Print)] after 
finishing registration adjustment.  (If the colors are still off after calibration, 
repeating calibration may improve the results.)

TEXT AND LINES ARE FAINT AND DIFFICULT TO 
SEE
Check Solution
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 could become faint 
converted to black, select [Text To Black] or [Vector To Black] on the [Image 
Quality] tab of the printer driver. (Raster data such as bitmap images cannot be 
adjusted.)
