Operating System Temporarily change settings for jobs that are printed now Permanently change default settings 1 Change configuration settings (For example, to add an optional tray or to enable or disable a driver feature such as "Allow manual duplexing") Mac OS X v.
● Printing multiple pages on one sheet of paper (N-up printing) ● Creating and using Quick Sets ● Reducing or enlarging ● Printing on different paper for the first page ● Changing the print quality ● Restoring the default printer-driver settings For manual duplexing, see Printing on both sides (duplexing manually) .
Printing in grayscale If you have a document that you created in color, it will automatically print in color. Or, you can set the printer to print a color document in grayscale (black and white) only. ● Windows: Select the Print In Grayscale option on the Color tab of the printer driver.
Printing multiple pages on one sheet of paper (N-up printing) N-up printing is the ability to print multiple pages on one sheet of paper. The pages will appear decreased in size. You can specify up to nine pages per sheet, and they will be arranged on the sheet as shown in the following figures if you use the default arrangement.
Printing on different paper for the first page Printing on different paper for the first page is useful if, for example, you are printing a letter that uses letterhead on the first page and plain sheets for the subsequent pages. The size for all pages of the print job must be the same in the printer driver.
Selecting an output location The printer comes with the top output bin and a rear output door for printing to a straight- through paper path. Print jobs emerge from the top output bin when the rear output door is closed. Print jobs emerge from the back of the printer when the rear output door is open.
Printing on special media Printing speeds might be automatically reduced when printing on any special print media. Printing on envelopes ● Load envelopes into tray 1 only. ● Do not load more than 10 envelopes into tray 1. ● The weight of the envelope paper should not exceed 90 g/m 2 (24 lb).
3. Slide the side-width guides in tray 1 outward until they are slightly wider than the envelopes. 4. Place the stack of envelopes into the tray with the side to be printed on facing up and with the short edge leading into the printer. The stamp end must enter the printer first.
CAUTION To avoid damaging the printer, use only labels that are recommended for laser printers. To prevent serious jams, always use tray 1 to print on labels and always use the straight- through paper path. Never print on the same sheet of labels more than once or print on a partial sheet of labels.
CAUTION To avoid damaging the printer, use only transparencies that are recommended for laser printers. To prevent serious jams, always use tray 1 to print transparencies. ● Load transparencies into tray 1 only. ● Select Transparencies as the Type (Windows) or the Paper Source (Macintosh) in the Print dialog box or the printer driver.

5 Color This chapter describes how the printer provides great color printing. This chapter also describes ways to produce the best possible color prints.
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.
Note Factors such as the type of monitor you use and the room's 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.
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 printer's color options.
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.
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.
6 Maintenance This chapter contains information about these maintenance topics: ● Managing supplies ● Cleaning the printer ● Calibrating the printer ENWW 67.
Managing supplies For warranty information about these supplies, see Print Cartridge Limited Warranty Statement . Supplies life The life of the imaging drum depends on the number of black-only or color pages that print jobs require.
Note If the printer is connected to the network, you can set the HP Toolbox to notify you by e-mail when a print cartridge is low or the imaging drum is near the end of its useful life. If the printer is directly connected to a computer, you can set HP Toolbox to notify you when supplies are low.
To recycle supplies, place the used supply in the box in which the new supply arrived. Use the enclosed return label to send the used supply to HP for recycling. For complete information, see the recycling guide that is included with each new HP supply item.
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.
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.
7 Problem solving This troubleshooting information is organized to help you resolve printing problems. Choose the general topic or type of problem from the following list.
Resolving problems that did not generate messages If the printer is not responding properly, complete the steps in the following checklist, in order. If the printer does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the problem, you can stop without performing the rest of the steps on the checklist.
9. Print a short document from a different program that has worked in the past. If this solution works, then the problem is with the program you are using. If this solution does not work (the document does not print) complete these steps: a. Try printing the job from another computer that has the printer software installed.
Checking the network It is recommended that you use the HP color LaserJet 2550 CD-ROM to install and set up the printer on a network. Follow these steps to see if the problem is caused by the network. ● When you printed the Configuration page, an HP Jetdirect configuration page should have printed if the printer is network-enabled.
Solving general printing problems In addition to the problems listed in this section, see Solving common Macintosh problems if you are using a Macintosh computer, and see Solving PostScript (PS) errors if you are using the PS driver. The print job is extremely slow.
The printer pulls paper or print media from the wrong tray. Cause Solution The Source (tray) selection might be incorrect. ● For Windows, ensure that the Source is selected from the Print dialog box (which is part of the program) if possible or from the printer driver.
The printer does not recognize a DIMM that is installed. Cause Solution The DIMM is not recognized in the printer driver. Set the printer driver to recognize the DIMM. See Enabling memory . The DIMM is not properly installed. Remove the DIMM, and reinstall it.
Pages print, but not all of the colors print, or the pages are completely blank. Cause Solution If one color is completely missing, the sealing tape might not have been removed completely from the print cartridge. Remove the print cartridge for the missing color and make sure all the sealing tape has been removed completely.
The printer prints, but the text is wrong, garbled, or incomplete. Cause Solution If the printer is connected to a computer, the operating system is malfunctioning. Check the operating system. If you do not know how to use the following method, see the documentation that came with the computer.

Secondary light patterns for Printer Status lights This section describes the secondary light patterns that you can display when you experience an Accessory error. Secondary light patterns provide more information about the specific type of error that occurred.
Clearing jams Occasionally, paper or other print media can become jammed during a print job. Some causes include the following events: ● The input trays are loaded improperly or overfilled. ● Tray 2 or optional tray 3 is removed during a print job.
2. Remove the imaging drum by pushing it away from you and lifting it out of the printer. You cannot reach jams by removing the print cartridges. 3. Complete one of these steps: ● If the leading edge of the print media is visible, carefully and slowly pull the print media out of the printer.
2. Complete one of these steps: ● If the jam has already partially entered the printer, see To clear jams from inside the printer . ● If the jam is only in the input tray, remove the jammed sheet by pulling it out by the visible edge. Realign all of the paper in the tray and go to step 4.
To clear jams from output areas CAUTION Jams in these areas might result in loose toner on the page. If you get toner on your clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.) 1. Complete one of these steps: ● If the jammed media is not almost completely visible from the top output bin, go to step 2.
5. Rotate the locks on the fuser to the unlocked position. 6. Grasp the fuser handles and pull to remove the fuser from the printer. WARNING! The parts on the internal surface of the fuser are very hot. To avoid burning yourself, do not touch those parts.
Solving print-media problems For best results, make sure that the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges. For best-quality color printing, use a smooth type of paper.
Solving print-quality problems If your document is printing but the quality is not what you expected, start by using the print- quality checklist. Print-quality checklist General print-quality problems can be solved by using the following checklist: 1.
Light print or fade Toner specks Dropouts Vertical lines Gray background Toner smear Loose toner Repetitive defects on the front Repetitive defects on the back Misformed characters Curl or wave Page s.
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.
Dropouts Faded areas, generally rounded, occur randomly on the page. ● A single sheet of print media might be defective. Try reprinting the job. ● The moisture content of the paper is uneven or the paper has moist spots on its surface. Try different paper, such as high-quality paper intended for laser printers.
Gray background The amount of background toner shading becomes unacceptable. ● Perform a calibration. See Calibrating the printer . ● Use a different paper with a lighter basis weight. See Print-media specifications . ● Check the printer environment.
Loose toner The toner smears easily when touched. ● In the printer driver, select the Paper tab and set Type is to match the type of media on which you are printing. Print speed might be slower if you are using heavy paper. ● Check the paper type and quality.
Repetitive defects on the back Marks repeatedly appear at even intervals on the unprinted side of the page. ● Internal parts might have toner on them. The problem will likely correct itself after a few more pages. ● Clean the printer. See Cleaning the printer .
Curl or wave The printed page is curled or wavy. ● Turn over the stack of paper in the tray. Also try rotating the paper 180 degrees in the input tray. ● Set the correct Type in the printer driver. Heavier paper might take longer to print. ● Open the rear output door to print to the straight-through paper path.
Wrinkles or creases The printed page contains wrinkles or creases. ● Make sure that paper is loaded properly. ● Turn over the stack of paper in the input tray, or try rotating the paper 180 degrees in the input tray. ● Open the rear output door to print to the straight-through paper path.
Random image repetition If an image that appears at the top of the page (in solid black) repeats farther down the page (in a gray field), the toner might not have been completely erased from the last job. The repeated image might be lighter or darker than the field in which it appears.
Note Whenever you are experiencing color-related issues, calibrate the printer before trying any other steps. See Calibrating the printer . Only black prints Missing or incorrect color Color prints in.
Missing or incorrect color One or more colors are not printing, or are inaccurate. ● Perform a calibration. See Calibrating the printer . ● You have changed the color settings manually. Return the color setting to Automatic. See Changing the color settings .
Colors do not match The colors on the printed page do not match the colors as they appear on the screen. ● Perform a calibration. See Calibrating the printer . ● The colors on your computer monitor differ from the printer output. Try selecting Screen Match in the Color tab of the printer driver.
