Troubleshooting

Checking an unresponsive

printer

If your printer is not responding, make sure:

The power cord is plugged into the printer and a properly

grounded electrical outlet.

The electrical outlet is not turned off by any switch or breaker.

The 

Ground Fault Circuit Interrupter

 (GFCI) has not tripped.

From the back of the printer, press the GFCI Reset button

located above the printer power cord.

The printer is not plugged into any surge protectors,

uninterrupted power supplies, or extension cords.

Other electrical equipment plugged into the outlet is working.

The printer is turned on.

The printer cable is securely attached to the printer and the

host computer, print server, option, or other network device.

Once you have checked each of these possibilities, turn the printer

off and then back on. This often fixes the problem.

Door A will not shut properly

Make sure the green paper jam clearance lever behind Door A is

in place:

Press down on the white release lever beneath Door A at the

top of the printer, and then open the door.

Press the A1 green lever down to its normal position.

Close Door A.

Solving color quality problems

This section helps answer some basic color-related questions and

describes how some of the features provided in the Quality menu

can be used to solve typical color problems.

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 can be combined to create yellow.

Televisions and computer monitors create colors in this manner.

RGB color is a method of describing colors by indicating the

amount of red, green, or blue needed to produce a certain 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 programs typically specify document color using RGB

or CMYK color combinations. Additionally, they allow users to

modify the color of each object in a document. For more

information, see the software program Help topics.

How does the printer know what color to print?

When a user prints a document, information describing the type

and color of each object is sent to the printer. The color

information is passed through color conversion tables that

translate the color into the appropriate amounts of cyan,

magenta, yellow, and black toner needed to produce the

desired color. The object information determines the

application of color conversion tables. 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.

Should I use PostScript or PCL emulation printer software?

What settings should I use for the best color?

The PostScript driver is strongly recommended for best color

quality. The default settings in the PostScript driver provide the

preferred color quality for the majority of printouts.

Why doesn't the printed color match the color I see on the

computer screen?

The color conversion tables used in Auto Color Correction mode

generally approximate the colors of a standard computer

monitor. However, because of technology differences that exist

between printers and monitors, there are many colors that can

also be affected by monitor variations and lighting conditions.

For recommendations on how the printer color sample pages

may be useful in solving certain color-matching problems, see

the question, “How can I match a particular color (such as a

corporate logo)?”

The printed page appears tinted. Can I adjust the color?

Sometimes a printed page may appear tinted (for example,

everything printed seems to be too red). This can be caused by

environmental conditions, paper type, lighting conditions, or

user preference. In these instances, adjust the Color Balance

setting to create a more preferable color. Color Balance provides

the user with the ability to make subtle adjustments to the

amount of toner being used in each color plane. Selecting

positive or negative values for cyan, magenta, yellow, and black

(from the Color Balance menu) will slightly increase or decrease

the amount of toner used for the chosen color. For example, if

a printed page has a red tint, then decreasing both magenta

and yellow could potentially improve the color balance.

My color transparencies seem dark when they are projected.

Is there anything I can do to improve the color?

This problem most commonly occurs when projecting

transparencies with reflective overhead projectors. To obtain

the highest projected color quality, transmissive overhead

projectors are recommended. If a reflective projector must be

used, then adjusting the Toner Darkness setting to 1, 2, or 3 will

lighten the transparency. Make sure to print on the

recommended type of color transparencies.

What is manual color correction?

When manual color correction is enabled, the printer employs

user-selected color conversion tables to process objects.

However, Color Correction must be set to Manual, or no

user-defined color conversion will be implemented. Manual

color correction settings are specific to the type of object being

printed (text, graphics, or images), and how the color of the

object is specified in the software program (RGB or CMYK

combinations).

Notes:

Manual color correction is not useful if the software

program does not specify colors with RGB or CMYK

combinations. It is also not effective in situations in which

the software program or the computer operating system

controls the adjustment of colors.

The color conversion tables—applied to each object when

Color Correction is set to Auto—generate preferred colors

for the majority of documents.

To manually apply a different color conversion table:

From the Quality menu, select Color Correction, and then

select Manual.

From the Quality menu, select Manual Color, and then

select the appropriate color conversion table for the

affected object type.

How can I match a particular color (such as a corporate logo)?

From the printer Quality menu, nine types of Color Samples sets

are available. These are also available from the Color Samples

page of the Embedded Web Server. Selecting any sample set

generates a multiple-page printout consisting of hundreds of

colored boxes. Either a CMYK or RGB combination is located on

each box, depending on the table selected. The observed color

of each box is obtained by passing the CMYK or RGB

combination labeled on the box through the selected color

conversion table.
By examining Color Samples sets, a user can identify the box

whose color is the closest to the desired color. The color

combination labeled on the box can then be used for modifying

the color of the object in a software program. For more

information, see the software program Help topics. Manual

color correction may be necessary to utilize the selected color

conversion table for the particular object.
Selecting which Color Samples set to use for a particular

color-matching problem depends on the Color Correction

setting being used (Auto, Off, or Manual), the type of object

being printed (text, graphics, or images), and how the color of

the object is specified in the software program (RGB or CMYK

combinations). When the printer Color Correction setting is set

to Off, the color is based on the print job information; and no

color conversion is implemented.

Note: The Color Samples pages are not useful if the software

program does not specify colors with RGB or CMYK

combinations. Additionally, certain situations exist in which the

software program or the computer operating system adjusts

the RGB or CMYK combinations specified in the program

through color management. The resulting printed color may

not be an exact match of the Color Samples pages.

What are detailed Color Samples and how do I access them?

Detailed Color Samples sets are available only through the

Embedded Web Server of a network printer. A detailed Color

Samples set contains a range of shades (displayed as colored

boxes) that are similar to a user-defined RGB or CMYK value. The

likeness of the colors in the set are dependent on the value

entered in the RGB or CMYK Increment box.
To access a detailed Color Samples set from the Embedded Web

Server:

Open a Web browser.
In the address bar, type the network printer IP address.
Click Configuration.
Click Color Samples.
Click Detailed Options to narrow the set to one color range.
When the Detailed Options page appears, select a color

conversion table.

Enter the RGB or CMYK color number.
Enter an Increment value from 1–255.

Note: The closer the value is to 1, the narrower the color

sample range will appear.

Click Print to print the detailed Color Samples set.
