Troubleshooting
Solving color quality problems
This section helps answer some basic color-related questions.
Frequently asked questions (FAQ) about color printing
What is RGB color?
Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in nature. 
For example, red and green light can be combined to create yellow light. Televisions and computer monitors create colors in 
this manner. RGB color is a method of describing colors by indicating the amount of red, green, and blue light needed to 
reproduce a particular color.
What is CMYK color?
Cyan, magenta, yellow, and black inks or toners can be printed in various amounts to produce a large range of colors 
observed in nature. For example, cyan and yellow can be combined to create green. Printing presses, inkjet printers, and 
color laser printers create colors in this manner. CMYK color is a method of describing colors by indicating the amount of 
cyan, magenta, yellow, and black needed to reproduce a particular color.
How is color specified in a document to be printed?
Software applications typically specify document color using RGB or CMYK color combinations. Additionally, they 
commonly let users modify the color of each object in a document. Since the procedures to modify colors vary depending 
on the application, see the software application Help section for instruction.
How does the printer know what color to print?
When a user prints a document, information describing the type and color of each object in the document is sent to the 
printer. The color information is passed through color conversion tables that translate the color into appropriate amounts of 
cyan, magenta, yellow, and black toner needed to produce the desired color. The object type information lets different color 
conversion tables be used for different types of objects. For example, it is possible to apply one type of color conversion 
table to text while applying a different color conversion table to photographic images.Incorrect margins Guides in the selected tray are set 
for a different size paper than 
what is loaded in the tray.Move the guides in the tray to the proper positions 
for the size loaded.
Skewed print
(Print is inappropriately 
slanted.)Guides in the selected tray are not 
in the correct position for the 
paper size loaded in the tray.Move the guides in the tray to the proper positions 
for the size loaded.
Blank pages The toner cartridges are defective 
or empty.Replace the toner cartridges.
Solid color pages The toner cartridges are defective.
Your printer requires servicing.Replace the toner cartridges.
