Using Help The printer driver has Help dialog boxes that can be activated from the Help button in the printer driver, the F1 key on the computer keyboard, or the question mark symbol (?) in the upper-right corner of the printer driver. These Help dialog boxes give detailed information about the specific printer driver. Help for the printer driver is separate from the Help for your program.

HP Toolbox

You must perform a complete software installation to use the HP Toolbox. The HP Toolbox provides links to printer status information and help information, such as this user guide; and tools for diagnosing and solving problems. You can also view explanations and animations of light messages on the control panel. See Maintenance for more information.
Software for network installations only
This software is available only when the printer is connected to a network. HP Web Jetadmin HP Web Jetadmin is intended for printer management in commercial and enterprise networks. While the HP Toolbox is used to manage a single printer, HP Web Jetadmin is used to manage groups of printers and other devices. Download this software from the HP website at http://www.hp.com/go/webjetadmin. The HP Web Jetadmin website provides HP Web Jetadmin software in many languages. HP Web Jetadmin is available only if the printer is connected to an Internet protocol- (IP-) based network. This browser-based software can be installed on one of the following supported platforms: Microsoft Windows 2000 or XP Red Hat Linux SuSE Linux
Starting HP Web Jetadmin After you install the HP Web Jetadmin software, you can start it in a supported Web browser on any computer by typing one of the following Web addresses: http://server.domain:port/ where "server.domain" is the server hostname and "port" is the port number that you selected during installation. (The default port is 8000.) This information is available in the url.txt file, which is stored in the folder where HP Web Jetadmin is installed. http://ipaddress:port/ where "ipaddress" is the IP address of the computer on which HP Web Jetadmin is installed. For settings that appear in both the printer driver and HP Web Jetadmin, changes that are made in the printer driver override changes that are made in HP Web Jetadmin.

Software for Macintosh

For Mac 9.1, the Apple LaserWriter 8 driver must be installed to use the PPD file. Use the Apple LaserWriter 8 driver that came with your Macintosh. For Mac OS X, use Print Center to print. The printer includes the following software for Macintosh computers.

1. Make sure that print media is loaded in the printer. 2. On the File menu, click Page Setup or a similar command. Make sure that the settings are correct for this document. 3. From the File menu, click Print, Print Setup, or a similar command. The Print dialog box opens. 4. Select this printer and change settings as necessary. Do not change any settings, such as page size or orientation, that you set in the Page Setup dialog box. 5. If this print job is for a standard size and weight of paper, you probably do not need to change the Source is (tray), Type is, or Size is settings, and you can go to step 7. Otherwise, go to step 6. 6. If this print job is to be printed on a non-standard size or weight of paper, select how the printer pulls paper. To print by Source (tray), select the tray in the Print dialog box, if possible. To print by Source (tray) when this setting is not available in the Print dialog box, click Properties, and on the Paper tab, select the tray in the Source is field. To print by Type or Size, click Properties and, on the Paper tab, select the type or size in the Type is or Size is field. (For some paper, such as letterhead, you will set both the Type and Size.) Always print by Type for special print media such as labels or transparencies.
7. If you have not yet done so, click Properties. The printer driver opens. 8. On the various tabs, set any settings that you want that did not appear in the Page Setup or Print dialog box. For more information about printer-driver settings, see Features in the printer driver. 9. By default, the printer prints to the top output bin, which is the best location for most print jobs, including transparencies. For labels, heavy paper, or other special print media, lower the rear output door on the printer. 10. Select the Print command to print the job.
To print from the Macintosh OS
1. Make sure that paper is loaded in the printer. 2. On the File menu, click Page Setup. 3. Make sure that this printer is selected on the Format for pop-up menu. 4.

This chapter describes how the printer provides great color printing. This chapter also describes ways to produce the best possible color prints. The following topics are covered: Using color Managing color options Matching colors

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 ImageREt 2400

Image REt 2400 provides 2400 dots-per-inch (dpi) color laser-class quality through a multilevel 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 HP's multilevel printing process, result in a 600-by-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.

Cleaning the printer

During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.

To clean the engine

Note The following procedure must be performed from the HP Toolbox. To clean the engine when the computer is running an operating system that does not support HP Toolbox, see the latebreaking Readme on the root of the CD-ROM, or visit http://www.hp.com/support/clj2550. 1. Make sure that the printer is turned on and in the Ready state. 2. Open the HP Toolbox. 3. On the Troubleshooting tab, click Maintenance, click Cleaning Page and then click Print. A page with a pattern prints from the printer. 4. At the printer, remove any print media that might be in tray 1. 5. Remove the page that printed and load it face-down into tray 1.
6. At the computer, press Clean.

Calibrating the printer

The printer automatically calibrates at various times. You can adjust the calibration settings by using the HP Toolbox. Environmental differences, aging print cartridges, aging toner, and an aging imaging drum might cause fluctuations in image density. The printer accounts for this with image stabilization control. The printer automatically calibrates at various times to maintain the highest level of print quality. You can also request a calibration by using the HP Toolbox. The printer does not interrupt a print job to calibrate. It waits until the job is complete before calibrating or cleaning. While the printer is calibrating, it pauses printing for the time that is required to complete the calibration.
To calibrate the printer at the printer
Press (GO) and (ROTATE CAROUSEL) simultaneously to start a calibration.
To calibrate the printer from the HP Toolbox
Note This procedure applies to Windows operating systems only. Macintosh users should calibrate the printer manually using the procedure above. 1. Open the HP Toolbox in one of these ways: On the desktop, double-click the HP Toolbox icon. On the Start menu, point to Programs, point to HP color LaserJet 2550, and click HP Toolbox.
2. On the Troubleshooting tab, click Diagnostic Tools (on the left side of the screen). 3. Click Color Calibration.

Resolving problems that did not generate messages

5. Print a Demo page from the HP Toolbox. If the page prints, the problem is with the printer driver. Try printing from the other printer driver. For example, if you are using the PCL 6 printer driver, print from the PS printer driver. 6. Try printing from a different program. If the page prints correctly, the problem is with the program from which you were printing. 7. Restart the computer and the printer and try printing again. If the problem is not resolved, choose one of these options: If the problem is affecting all printed pages, see Solving issues with all printed documents. If the problem is affecting only pages printed in color, see Solving issues with color documents.
Solving issues with all printed documents
The following examples depict letter-size paper that has passed through the printer shortedge first. These examples illustrate problems that would affect all pages that you print, whether you print in color or in black only. The topics that follow list the typical cause and solution for each of these examples.
Light print or fade Gray background

Toner specks Toner smear

Random image repetition (light)

Light print or fade

A vertical streak or an incorrect or faded color area appears on the page.
The print media might not meet HP specifications (for example, the paper is too moist or too rough). See Print-media specifications. One or more print cartridges are low. If you are using non-HP print cartridges, no messages appear on the printer control panel or in the HP Toolbox. The imaging drum might be low or empty. Print the Supplies Status page to check the remaining life. Replace the imaging drum if it is low or empty. If none of the print cartridges or the imaging drum is low or empty, remove the print cartridges one at a time and inspect the toner roller in each to see if the roller is damaged. If so, replace the print cartridge. If the light printing is on the left side of the page, the carousel might be dislocated. Service is required. If the problem is not resolved, see If the problem is not resolved.

Toner specks

Specks of toner occur randomly on the page. The print media might not meet HP specifications. For example, the paper is too moist or too rough. See Print-media specifications.
The paper path might need cleaning. See Cleaning the printer. If the problem is not resolved, see If the problem is not resolved.
