Canceling a print job
A print job can be canceled from a program, from a print queue, or from the  (Cancel Job ) button
on the printer.
● If the printer has not started printing, first try to cancel the job within the program that sent the
print job.
● If the print job is waiting in a print queue or print spooler such as the  Printers folder (Printers or
faxes  in Windows 2000 or Windows XP), try to delete the job from there next.
● If the print job is  already printing, press 
 (Cancel Job ) on the printer. The printer finishes
printing any pages that are already moving through the printer and deletes the remainder of the
print job.
● Pressing 
 (Cancel Job ) cancels only the current job in the printer. If more than one print job is
in printer memory, you must press 
 ( Cancel Job ) once for each job after the job starts printing.
The Ready  light will blink and the  Cancelling print will display in the message area.

Using color
This printer offers great color as soon as you set it up. It provides a combination of automatic color
features to generate excellent color results for the general user, plus sophisticated tools for the
experienced color user.
The printer provides carefully designed and tested color tables to provide smooth, accurate color
rendition of all printable colors.
HP provides free online tools to help businesses of all sizes with their color printing. HPs Office
Color Printing Center (
http://www.hp.com/go/color) identifies solutions and information on creating
finished projects.
HP ImageREt 2400
ImageREt 2400 provides 2400 dots-per-inch (dpi) color laser-class quality through a multi-level
printing process. This process precisely controls color by combining up to four colors within a single
dot and by varying the amount of toner in a given area. ImageREt 2400 has been improved for this
printer. The improvements offer trapping technologies, greater control over dot placement, and more
precise control of toner  quality in a dot. These new technologies, coupled with HPs multi-level
printing process, result in a 600 x 600 dpi printer that provides 2400-dpi color laser-class quality with
millions of smooth colors.
In contrast, the single-level printing process found in the default mode of other color laser printers
does not allow the colors to be mixed within a single dot. This process, called dithering, significantly
hinders the ability to create a wide range of  colors without reduced sharpness or visible dot structure.
Media selection
For the best color and image quality, it is important to select the appropriate media type from the
software printer menu or from the printer driver. See 
Print-media specifications for more information.
Color options
Color options enable optimal color output automatically for diverse types of documents.
Color options use object tagging, which allows optimal color settings to be used for different objects
(text, graphics, and photos) on a page. The printer driver determines which objects are used on a
page and uses color settings that provide the best print quality for each object. Object tagging,
combined with optimized default settings, produces great color from the printer without having to
establish any special settings.
In the Windows environment, the  Automatic and Manual  color options are on the  Color tab in the
printer driver.
Standard red-green-blue (sRGB)
Standard red-green-blue (sRGB) is a worldwide color standard that was originally developed by HP
and Microsoft as a common color language for monitors, input devices (scanners and digital
cameras), and output devices (printers and plotters). It is the default color space that is used for HP
products, Microsoft operating systems, the World Wide Web, and most office software that is sold
today. The sRGB  standard is representative of the typical Windows computer monitor and is the
convergence standard for high-definition television.

NOTEFactors such as the type of monitor you use and the rooms lighting can affect the
appearance of colors on your screen. For more information, see 
Matching colors .
The latest versions of Adobe® PhotoShop®, CorelDRAW™, Microsoft Office, and many other
applications use sRGB to communicate color. Most importantly, as the default color space in
Microsoft operating systems, sRGB has gained broad adoption as a way to exchange color
information between software programs and devices by using a common definition that assures that
typical users will experience greatly improved color matching. The sRGB standard improves your
ability to match colors between the printer, the computer monitor, and other input devices (scanners
and digital cameras) automatically, without the need to become a color expert.

Managing color options
Setting color options to Automatic typically produces the best  possible print quality for color
documents. However, in some situations, you might want to print a color document in grayscale
(black and shades of gray) or to change one of the printers color options.
Print in grayscale or change the color options by using the settings on the  Color tab in the printer
driver.
Print in Grayscale
Selecting the  Print in Grayscale  option from the printer driver prints a document in black and
shades of gray. This option is useful for printing color documents that will be photocopied or faxed.
When  Print in Grayscale  is selected, the printer goes into monochrome mode.
Selecting  Print in Grayscale  in the Print Quality  options on the  Paper Quality tab, will allow you to
change the settings to accommodate the types of jobs that you are printing. The following are the
settings:
● FastRes 1200
: This setting uses FastRes 1200 to provide  fine-line detail at 1200 x 1200 dpi.
● ProRes 1200
: This setting provides ProRes 1200 output with Resolution Enhancement
technology (REt) for improved text.
Automatic versus Manual color adjustment
The  Automatic  color adjustment option optimizes the neutral gray color treatment, and\
 the edge
enhancements that are used for each element in a document. For more information, see your printer-
driver online Help.
NOTE Automatic  is the default setting and is recommended for printing all color documents.
Use the Manual color adjustment option to adjust the neutral gray color treatment, and the edge
enhancements for text, graphics, and photographs. To gain access to the Manual color options, on
the  Color  tab, click  Manual, and then click  Settings.
Change color options
Use the Manual color adjustment to adjust the  Color (or Color Map ) options.
NOTESome software programs convert text or graphics to raster images. In these cases,
the  Photographs  setting also controls the text and graphics.

Halftone options
Halftoning is the method by which the printer mixes the four primary colors (cyan, magenta, yellow,
and black) in varying proportions to create millions of colors. Halftone options affect the resolution
and clarity of your color output. The two halftone options are Smooth and Detail .
● The Smooth  option provides better results for large, solid-filled print areas. It also enhances
photos by smoothing out fine color gradations. Choose this option when uniform and smooth
area fills are the most important attributes.
● The Detail  option is useful for text and graphics that require sharp distinctions among lines or
colors, or images that contain a pattern or a high level of detail. Choose this option when sharp
edges and details are the most important attributes.
Edge Control
The  Edge Control  setting determines how edges are rendered. Edge Control consists of two
components: Adaptive Halftoning and Trapping. Adaptive Halftoning increases the edge sharpness.
Trapping reduces the effect of color-plane misregistration by slightly overlapping the edges of
adjacent objects. The following levels of edge control are available:
● Off sets Trapping and Adaptive Halftoning to Off.
● Normal  provides the default trapping settings. Adaptive Halftoning is set to On.
● Maximum  provides the most trapping. Adaptive Halftoning is set to On.
RGB Color
The RGB Color  option determines how colors are rendered.
● Select 
Default (sRGB)  for most printing needs. This setting instructs the printer to interpret
RGB color as sRGB, which is the accepted standard of Microsoft and the World Wide Web
Organization.
● Select 
AdobeRGB  for documents that use the AdobeRGB color space rather than sRGB. For
example, some digital cameras capture images in AdobeRGB, and documents that are
produced with Adobe PhotoShop use the AdobeRGB color space. When printing from a
professional software program that uses AdobeRGB, it is important that you turn off the color
management in the software program and allow the printer software to manage the color space.
● Photo Image
 interprets the RGB color as if it were printed as a photograph using a digital mini-
lab. It is designed to render the deeper, more saturated colors differently than Default mode.
Use this setting for printing photos.
● Device
 sets the printer to print RGB data in raw device mode. To render photographs properly
when this option is selected, you must manage color in the program in which you are working or
in the operating system.
● Vivid  instructs the printer to increase the color saturation in the midtones. Less colorful objects
are rendered more colorfully. This value is recommended for printing business graphics.

Neutral Grays
The Neutral Grays  setting determines the method for creating gray colors that are used in text,
graphics, and photographs.
● Black Only  generates neutral colors (grays and black) by using only black toner. This option
guarantees that neutral colors do not have a color cast.
● 4-Color  generates neutral colors by combining all four colors of toner. This option produces
smoother gradients and transitions to non-neutral colors. It also produces the darkest possible
black.

Matching colors
The process of matching printer output color to your computer screen is quite complex because
printers and computer monitors use different methods of producing color. Monitors display colors by
light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK
(black, yellow, cyan, and magenta) process.
The following factors can influence your ability to match printed colors to those on your screen:
●Print media
● Printer colorants (inks or toners, for example)
● Printing process (inkjet, press, or laser technology, for example)
● Overhead lighting
● Programs
● Printer drivers
● Computer operating system
● Monitors
● Video cards and drivers
● Operating environment (very humid or very dry)
● Personal differences in perception of color
Keep these factors in mind if colors on your screen do not perfectly match your printed colors. For
most users, the best method for matching colors on your screen to your printer is to print sRGB
colors. The printer uses sRGB and automatically optimizes color output.
You can use HP ToolboxFX to print a palette of the MicroSoft Office Basic Colors. The palette can be
used to select the final color you want to use in your printed document.
1. In HP ToolboxFX, select the  Help folder.
2. In the  Print Quality Troubleshooting  section, select Print Basic Colors .
This palette shows the actual printed color that you will get when you select the basic color in your
Microsoft Office application.
