Common Printing Tasks

Selecting Media

Many types of paper and other print media can be used with the printer, within certain specifications. Using media that does not meet the specifications outlined in this chapter can increase the incidence of media jams, contribute to repair and maintenance costs, and cause premature wear, print quality problems, and problems requiring service. This service might not be covered by the HP warranty or service agreements. Before purchasing media or specialized forms, test a small quantity in the printer. Make sure your media supplier obtains and understands the media and print media specifications in the HP LaserJet Printer Family Paper Specifications Guide. (For ordering information, see Accessories, Options, and Related Products in chapter 8.)
It is possible that media could meet all of the specifications in this chapter and still not print satisfactorily. This might be caused by abnormal characteristics of the printing environment or other variables over which HP has no control, such as extremes in temperature and humidity.
Use only print media that meets the specifications outlined in this chapter. Do not attempt to print unsupported sizes or weights of media or other unsupported media. For more information on supported media, see Supported Media Weights and Sizes for Input Trays on the next page. Always handle transparencies and glossy media by their edges to avoid fingerprints in the image area.

Selecting Media 59

Do not use media that has already passed through the printer or through a copy machine, even if there is no printing on the page. Recycled media can be used with this printer. Recycled media must meet the specifications shown in this chapter.
Supported Media Weights and Sizes for Input Trays
The following table lists the types and sizes of media supported by each input tray. For best results, use HP LaserJet paper or conventional white xerographic paper. The media should be good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, perforations, and curled or bent edges. For a complete list of media specifications, see the HP LaserJet Printer Family Paper Specifications Guide. For more information on orienting the media in each of the input trays, see the appropriate section later in this chapter.

Selecting Media 67

Preprinted Forms and Letterhead
Observe the following guidelines to avoid problems with preprinted forms and letterhead.
Forms and letterhead must have been printed with heat-resistant inks that will not melt, vaporize, or release hazardous emissions when subjected to the printer's fusing temperatures (approximately 374 F, or 190 C). The inks must be non-flammable and must not adversely affect any printer rollers. Forms and letterhead should be sealed in a moisture-proof wrapping to prevent moisture damage during storage. Inks must be completely dry on forms and letterhead before they are used in the printer. Ink that is not completely dry can come off the page during the fusing process.

Recycled Media

Choose recycled media that meets the same specifications as standard paper (see Supported Media Weights and Sizes for Input Trays earlier in this chapter). HP recommends that recycled media contain no more than five percent ground wood.
Envelopes can only be printed from tray 1. The weight of the envelope paper should not exceed 24 lb (90 g/m2) bond; otherwise, jamming might occur. For more information on printing envelopes, see Printing Envelopes from Tray 1 later in this chapter.

z z z z z z

Envelopes should lie flat, with less than 0.25 inches (6.35 mm) curl. Output envelopes to the left (face-up) output bin rather than to the top (face-down) output bin to reduce curl. The optional multi-bin mailbox does not support envelopes except in its left (face-up) output bin. Do not use envelopes with windows or clasps. Make sure envelopes are not wrinkled, nicked, or otherwise damaged. Envelopes with a peel-off adhesive strip or with more than one flap must use adhesives compatible with the printer's fusing temperatures (approximately 374 F, or 190 C). Extra flaps or strips can result in wrinkling or creasing, and can cause jamming. All folds must be well scored and sharply creased. Envelopes must be tightly constructed and should not contain air. Envelopes that contain air may wrinkle as they pass through the printer.

Selecting Media 69

CAUTION Use only transparencies supported for use in this printer, such as HP Color LaserJet transparencies (for ordering information, see Accessories, Options, and Related Products in chapter 8). Using transparencies that do not meet the specifications for this printer can cause poor print quality, media jams, and damage to the printer. Although this printer supports transparencies between 4 and 5 mils (0.10 to 0.13 mm) thick, HP recommends using 5-mil (0.13-mm) thick transparencies. To prevent damage to the printer, transparencies must be able to withstand the printer's fusing temperature (approximately 374 F, or 190 C). Handle transparencies by the edges. Oils from your fingers can be deposited on the transparencies, causing print quality problems.

Heavy Paper Stock

Heavy paper stock is any paper heavier than 28 lb up to 58 lb (105 to 216 g/m2) bond. Always print heavy paper stock from tray 1. In the printer driver, select Heavy Paper as the paper type on the Paper tab to ensure the correct finish on the media. Also, use the left (face-up) output bin to prevent media jams. For more information on changing the printer driver settings, see the online help.
Do not use extremely heavy paper stock (greater than 58 lb, or 216 g/m2 bond). Misfeeds, mis-stacking, media jams, poor toner fusing, poor print quality, and excessive mechanical wear can result.
Labels consist of three parts: the top or face sheet that the printer prints on, the adhesive, and the carrier sheet (also referred to as the backing or liner). When printing on labels with this printer, observe the following:
Top sheets, which are the printing surface, are usually composed of xerographic paper. Label top sheets must provide good toner adhesion. Carrier sheets must be compatible with the printer's fusing temperature (approximately 374 F, or 190 C) and the pressure of the fusing process. The carrier sheet also must be coated for easy release of the top sheet.

CAUTION

Do not remove labels from the carrier sheet and then print on the remaining labels; printer damage can result.
Adhesives must be able to withstand the printer's fusing temperature (approximately 374 F, or 190 C). The adhesives must not produce emissions that exceed exposure levels or threshold limits established by the U.S. Occupational Safety and Health Administration and other safety agencies. Adhesives must not come in direct contact with any part of the printer. No adhesive should be pressed out of the edges or between die-cuts (the cuts between individual labels). Labels should be arranged so that the carrier sheet is not exposed. Using label stock with spaces between the horizontal rows of labels might result in labels peeling off during printing, causing jams and possible printer damage. Labels might be specifically manufactured to leave a margin around the outside edges that correspond to the outer margins of the printable area. Do not remove the excess top sheet material from the carrier sheet.

Storing a Print Job

The user can download a print job to the printers hard disk without printing it. The user can then print the job at any time through the printers control panel. For example, a user may want to download a personnel form, calendar, time sheet, or accounting form that other users can access and print. To store a print job permanently on the hard disk, select the Stored Job option in the driver when printing the job.

Printing a Stored Job

The user can print a job stored on the printers hard disk from the control panel. 1 Press MENU repeatedly until PRIVATE/STORED JOBS MENU appears. Press ITEM until the desired job name appears. Press SELECT to select the job name. COPIES=1 appears. Press - VALUE + until the desired number of copies appears. Press SELECT to print the job.

Deleting a Stored Job

Jobs stored on the printers hard disk can be deleted from the control panel. 1 Press MENU repeatedly until PRIVATE/STORED JOBS MENU appears. Press ITEM until the desired job name appears. Press SELECT to select the job. COPIES=1 appears. Press - VALUE until DELETE appears. Press SELECT to delete the job.

Storing a Print Job 101

Variable Data Printing
Some applications produce documents containing two types of information: static information like background patterns, and variable information that changes from page to page. In a print job, variable data printing separates the static and dynamic information and sends the static information to the printer only once. Pages print faster because repetitive information does not have to be processed separately for each page.
This feature is automatic. No user interaction is required.

Booklet Printing

Booklet printing allows the pages of a print job to be arranged so that the document can be folded and stapled or bound into a book. Booklet printing is supported in PostScript and PCL5c in Windows 3.x, 9x, NT 4.0, Windows 2000, and using the Booklet Maker for Macintosh.
Duplex printing must be selected in order to use the Booklet Printing feature. Offline Booklet Printing delivers the job to the top (face-down) output bin. The user can remove the job from the printer and bind or staple it. (Right and left binding options are provided for Asian languages.) The user may also insert one full blank page (2 booklet pages) at any location in the booklet. Inline Booklet Printing uses a finishing device like a multi-bin mailbox to staple or bind the booklet. (Booklet Printing requires the document be sent to the left (face-up) output bin instead of the top (face-down) output bin.) The user selects the destination of the print job, and the software places the pages in the proper order for binding. Custom Order allows the user to specify the page sequence.

Booklet Printing 103

To download Type 1 fonts, Adobe Type Manager must be loaded and turned on.
HP LaserJet Utility (Macintosh)
HP LaserJet Utility allows control of features that are not available in the driver. The illustrated screens make selecting printer features from the Macintosh computer easier than ever. Use the HP LaserJet Utility to do the following:
Customize the printers control panel messages. Name the printer, assign it to a zone on the network, download files and fonts, and change most of the printer settings. Set a password for the printer. From the computer, lock out functions on the printers control panel to prevent unauthorized access. (See the printer software help.) Configure and set the printer for IP printing.
Managing Fonts and Forms on Disk 107

Using Color

Controlling Color Output with Printer Drivers
By varying the amount and pattern of the four toner colors applied to a page, the printer can produce more than 16 million colors. Use the printer drivers (the software installed with the printer) to control the color output for text, graphics, and photographs. The printer drivers enable computer applications to communicate with the printer and to use all of its features. Access to the printer drivers depends on the computer system. For example, in a system using Microsoft Windows, use the application's Print Setup command to access your printer driver. For specific instructions on accessing the printer driver, see the online help files for your operating system.
Applications override most printer settings, such as media size, copies, and media source. When possible, use application settings for adjustments.
Controlling Color Output with Printer Drivers 109
The color features of the driver are available on the properties page. Access the driver properties as it pertains to the specific operating system or application in use, then select the Color tab.

ColorSmart II

HP ColorSmart II technology optimizes the color and halftoning for each element in a document (such as text, graphics, and photographs).
HP ColorSmart II uses the Screen Match setting to reproduce all elements in a document. HP ColorSmart II uses a smooth halftone for photographs and raster graphics, and uses a detail halftone for text and vector graphics.This setting provides consistent color treatment for everything on a page. When Transparency is selected in the Paper tab of the printer driver, HP ColorSmart II chooses specialized colors to provide the best projection quality. HP ColorSmart II is also the most reliable setting for PANTONE* color reproduction. For more information on using PANTONE colors, see PANTONE Colors later in this chapter.

Manual Mode

For custom color printing jobs, you can turn off HP ColorSmart II defaults and set color adjustments manually. The Manual mode allows you to adjust the color settings for text, graphics, and photographs separately by manipulating the available settings. The following settings apply to all types of media:
HalftoneChanges the method used to produce lighter shades of solid colors. SmoothWorks well for solid areas, gradients, and photographs by smoothing out fine color gradations and providing accurate color reproduction. DetailWorks well for text, multiple-colored text, line art, and detail-oriented graphics by providing sharper edges.
Color AdjustmentChanges the color settings for elements on the page. Screen MatchColor is optimized for reproducing of sRGB monitor colors. (The term sRGB is generally used to define RGB, red/green/blue, color output for monitors.) This setting maximizes the similarities between the appearance of the printed document and the document as it appears on the monitor. Screen Match is the printer default input color source. VividSaturation of colors is enhanced to produce high-impact color appearance. OHT(Overhead Transparency) For optimized color quality for projection.
All settings in the printer driver will remain in effect until they are changed. The online help describes in more detail the printer color settings and options, and their effect on your output.
Controlling Color Output with Printer Drivers 111

ICC/CMS

Some applications and operating systems support specific color management systems (CMS):
ICC (International Color Consortium) is an international standard for color profiles that describe the color characteristics of devices, such as printers. ColorSync 2.x is Macintosh's color management system for System 7 and 8. ICM is Microsoft's color management system for Windows.
For information on downloading and selecting color profiles, see the online help. If you are generating customized color profiles, use the same printer driver settings for both generating the profiles and printing.

Black and White

Selecting Black and White in the Color tab allows your color documents to be printed as black and white documents with shades of gray. This setting allows you to view preliminary copies of slides and hard copy output quickly and still interpret your color information. Printing in black and white also works well for color information that you wish to photocopy or fax.
Automatic PANTONE Matching
The printer has a PANTONE Spot Name color matching utility. PANTONE has certified the printer and has mapped the PANTONE Spot Color names to the printers CMYK values. This color matching utility uses the certified mapping to provide the best PANTONE color matching for the printer. For the color matching utility to function, applications must pass the PANTONE names to the printer. Some applications substitute CMYK values to the printer if they cannot provide PANTONE names. If your application does not pass the PANTONE names to the printer, then the utility will be bypassed and color matching will depend on proper ink emulation. Selection of the proper ink emulation depends on the source of the palette (SWOP (Standard Web Offset Printing), EuroStandard, DIC, or None). The palette used for obtaining PANTONE CMYK values and the driver emulation mode setting should match.

Solving Printer Problems
Performing Basic Troubleshooting Steps
This chapter suggests steps to solve common problems that you might encounter while using the printer. If the printer does not work properly, check the following items first:
Is the printer connected to a live power source? Is the printer online? Are the communications cables from the printer to the network or the host computer connected? Are the parallel cables IEEE-1284 compliant? Are any messages displayed on the printer control panel? If you recently replaced a toner cartridge, did you remove the orange tab? Were the printer and its software installed correctly?
For more information on installation and set up, see the getting started guide. If you have questions that you do not find the answers to in this chapter, see the HP Customer Care information in the front of this manual.
Performing Basic Troubleshooting Steps 161

Working with Toner

HP recommends that you use HP LaserJet toner cartridges. HP has designed the printer, toner cartridges, and toner formula to work together to give you optimal image quality from the printer. If toner gets on clothing or carpet, wipe the toner off with a dry cloth and then wash with cold water. Warm water or the heat of a dryer will set the toner into the clothing or carpet.

Media Jam Locations

The following figure shows the locations of media jams in the printer paper path. Figure 15

Resetting the transfer life count without replacing the transfer kit can cause print quality problems and may damage the printer.

Print Quality Problems 195
Cause and Solution Repeating spots or specks of the same size and shape appear on almost all pages in the same area of the page. The repeating defects will generally be dark gray or black. If the defect is not acceptable, cleaning or replacing the imaging drum or the transfer drum might be necessary. If the defect occurs one or more times on each letter- or A4-sized page, the imaging drum should be replaced. If the defect occurs on every other letteror A4-sized page, then the transfer drum should be cleaned. For information on cleaning the transfer drum, see Cleaning the Transfer Drum later in this chapter. If cleaning the transfer drum does not correct the problem, replace the transfer drum or contact a local authorized HP dealer or service representative for service. For more information on replacing the imaging drum or the transfer drum, see the installation guide included with the drum kit or transfer kit. Unwanted marks of the same size and shape appear more than once in the same vertical area on transparencies only. The fuser roller is damaged. Replace the fuser. For more information on replacing the fuser, see the installation guide included with the fuser kit.
(Repetitive defects, continued)

Irregular wavy patterns

Irregular wavy patterns in solid fill backgrounds might indicate that the transfer charger needs to be cleaned. For more information on cleaning the transfer charger, see Cleaning the Transfer Charger later in this chapter.
Cleaning the Density Sensor
Clean the density sensor after replacing the imaging drum and when printed colors are inaccurate.
To clean the density sensor and erase lamp
1 Open the upper door on the right side of the printer. 2 On the inside of the door, locate the density sensor and the density sensor brush. Use the brush to brush off toner particles from the density sensor and the erase lamp. Then replace the brush. Note You can also use a hand wipe to clean the density sensor. To prevent scratches on the sensor, do not use any paper products, such as tissue or paper towels, to clean the sensor. 3 Close the upper right door.
Print Quality Problems 197
Cleaning the Transfer Drum
Perform these procedures only when there is an unacceptable repetitive defect and the only other solution is replacing the transfer drum. Many, but not all, repetitive defects can be removed using the following procedures. Defects that appear as light spots in dark areas of print are more likely to be corrected by this procedure than dark spots in unprinted areas. If the procedures are performed incorrectly or without proper care, the transfer drum can be permanently damaged. These procedures require the following items:

Paper This printer is suited for the use of recycled papers when the paper meets the guidelines outlined in the HP LaserJet Printer Family Paper Specifications Guide, HP part number 5010-6394. This printer is suited for the use of recycled paper according to DIN 19 309. The user guide is provided on CD-ROM, which allows the same high-quality information to be provided without consuming the large quantities of energy and natural resources required to produce traditional paper manuals.
