Software

The printer comes with helpful software, including printer drivers and optional software. For easy printer setup and access to the full range of printer features, HP recommends that you install the software that is provided. Check the installation notes and Readme files on the printer CD-ROM for additional software and languages. HP software is not available in all languages.
Operating systems and printer components
The printer CD-ROM contains the software components and drivers for users and network administrators. The printer drivers that are provided on the CD-ROM must be installed in order to take full advantage of printer features. The other programs are recommended, but are not required for operation. Check the installation notes and Readme files on the printer CD-ROM for more information. The CD-ROM includes software that is designed for users and network administrators who are operating in the following environments: Microsoft Windows 98 and Windows Millennium Edition (Me) Microsoft Windows NT 4.0 (parallel and network connections only) Microsoft Windows 2000, Windows XP, and Windows Server 2003 Apple Mac OS version 9.1 and later, and OS X version 10.1 or later

The autoselect process changes somewhat if you customize tray 1 operation (as explained in Customizing tray 1 operation) or if you set tray 1 for manual feed (as explained in Manually feeding media from tray 1).
Customizing tray 1 operation
The printer can be set to print from tray 1 if it is loaded, or to print only from tray 1 if the type of media that is loaded is specifically requested. See Paper Handling menu.
Setting TRAY 1 TYPE=ANY TRAY 1 SIZE=ANY
Explanation The printer usually pulls media from tray 1 first unless it is empty or closed. If you do not keep media in tray 1 all the time, or if you use tray 1 only to manually feed media, keep the default setting of TRAY 1 TYPE=ANY and TRAY 1 SIZE=ANY on the Paper Handling menu.

Chapter 2 Printing tasks

Setting TRAY 1 TYPE= or TRAY 1 SIZE= a type other than ANY
Explanation The printer treats tray 1 like the other trays. Instead of looking for media in tray 1 first, the printer pulls media from the tray that matches type and size settings that are selected in the software. In the printer driver, you can select media from any tray (including tray 1) by type, size, or source. To print by type and size of paper, see Printing by type and size of media (locking trays).
You can also determine whether the printer shows a prompt to ask if it can pull media from tray 1 if it cannot find the type and size that you requested in another tray. You can set the printer to always prompt you before pulling from tray 1 or only prompt you if tray 1 is empty. Set the USE REQUESTED TRAY setting on the System Setup submenu of the Configure Device menu.
Printing by type and size of media (locking trays)
Printing by type and size is a way to be sure that print jobs always print on the media that you want. You can configure the trays for the type, such as plain or letterhead, and size, such as letter or A4, that is loaded in them. If you configure the trays this way and then select a certain type and size in the printer driver, the printer automatically selects the tray that is loaded with that type or size. You do not have to select a specific tray (selecting by source). Configuring the printer this way is especially helpful if the printer is shared, and more than one person loads or removes media frequently. Some older model printers have a feature that "locks out" trays to prevent printing on the wrong media. Printing by type and size eliminates the need to lock trays. For more information about the types and sizes that each tray supports, see Supported sizes of print media. NOTE To print by type and size from tray 2, the optional trays, or the optional envelope feeder, you might have to to unload tray 1 and close it, or set TRAY 1 TYPE and TRAY 1 SIZE to types other than ANY on the PAPER HANDLING menu at the printer control panel. For more information, see Customizing tray 1 operation. Settings in a program or the printer driver override control-panel settings. (Program settings generally override printer-driver settings.)

Weight and sizes

See the following table for specifications when printing on custom or heavy paper. For more information, see Paper specifications.
Tray Tray 1 Tray 2 and optional 500-sheet tray
Minimum size 76 x 127 mm (3 x 5 inches) 148 x 210 mm (5.8 x 8.2 inches)
Maximum size 216 x 356 mm (8.5 x 14 inches) 216 x 356 mm (8.5 x 14 inches)
Supported weights 60 to 200 g/m2 (16 to 53 lb) 60 to 120 g/m2 (16 to 32 lb)
Guidelines for heavy paper
Follow these guidelines when printing on heavy paper: Paper heavier than 120 g/m2 (32 lb) should be printed only from tray 1. To reduce curl and other problems, print heavy paper from tray 1 to the rear output bin. To help prevent toner from rubbing off of the paper, some heavier paper types should be printed using a higher fuser mode. At the printer control panel, open the CONFIGURE DEVICE menu. On the PRINT QUALITY submenu, select FUSER MODES, and then select the media type that you want to modify. Select either HIGH 1 or HIGH 2 as the fuser mode. Using these modes helps prevent toner from rubbing off the page, but using them might slow the printer speed or create other problems, such as increased curl.
Guidelines for custom-size paper
Follow these guidelines when printing on any custom-size paper: Feed the paper short-edge first. In your program, set page margins at least 4.23 mm (0.17 inch) away from the edges. Set the custom size in the program, in the printer driver, or at the printer control panel. Make sure that you set the switch in the tray to Custom. See Setting custom paper sizes.
Additional guidelines for small or narrow paper
Follow these additional guidelines when printing on small or narrow paper: Do not attempt to print on paper smaller than 76 mm (3 inches) wide or 127 mm (5 inches) long. To reduce curl and other problems, print very small custom-size paper from tray 1 to the rear output bin. HP does not recommend printing large quantities of small or narrow paper. Printing large quantities of small or narrow paper can cause excessive wear on the print cartridge components that might result in toner leaking into the printer or might cause print-quality problems.

To uninstall the HP Toolbox by using Add/Remove Programs in the Windows control panel
1. Click Start. 2. Click Control Panel. NOTE In some versions of Windows, point to Settings, and then click Control Panel. 3. Double-click Add or Remove Programs. 4. Select hp LaserJet Toolbox from the list of programs, and then follow the onscreen instructions.
Managing and configuring printer drivers
Your system or network administrator can use the driver management and configuration solution to configure printer drivers before you install and deploy them within your environment. This is helpful when you configure printer drivers for multiple workstations or printers that share the same configuration. When you preconfigure your printer driver to match the printer hardware, you can gain access to all of the printer accessories through the driver. You can also configure most driver feature settings. Five of the driver features can be "locked." This means that you can choose not to allow users to change the duplex, print color as gray, input tray, output tray, and media type settings. (Some features might not apply to all printers. For example, some printers do not include color printing or duplexing.) The driver management and configuration solution saves time and reduces management costs. Previously, if an administrator wanted to configure printer drivers, the configuration had to be completed at each client workstation. Because the driver management and configuration solution offers multiple configuration options, administrators can create a single configuration, in a central location, that best fits their software installation and deployment strategy. The driver management and configuration solution also gives administrators more control over their printing environment, because they can deploy drivers that share the same configuration across an entire organization. They can use the "lock" feature to support organization initiatives. For example, if a printer includes a duplexer, locking the duplex setting ensures that all print jobs are printed on two sides to save paper. All of the controls can be deployed from a single computer. Two methods are available: HP Web Jetadmin software plug-in Customization utility

1. At the back of the printer, open the door on the stacker or stapler/stacker.
2. Carefully remove any jammed paper.
3. Close the door on the stacker or stapler/stacker.
4. If a jam message persists, a sheet is still jammed. Look for it in another location. Check the front of the accessory and carefully remove any jammed paper. (See Jam locations.) NOTE The output bin must be pushed down into the lowest position for printing to continue.
To clear staple jams from the optional stapler/stacker
NOTE Clear staple jams when the message JAM IN STAPLER appears on the printer controlpanel display. 1. On the right side of the stapler/stacker, turn the stapler unit toward the front of the printer until the unit clicks into the open position. Pull outward on the blue staple cartridge to remove it.
2. Rotate the green cover on the end of the staple cartridge upward, and remove the jammed staple.
3. Insert the staple cartridge into the stapler unit, and rotate the stapler unit toward the rear of the printer until the unit snaps into place.
The stapler needs to reload after clearing a staple jam, so the first few documents (up to five) might not be stapled. If a print job is sent and the stapler is jammed or is out of staples, the job will still print as long as the path to the stacker bin is not blocked.

Solving repeated jams

If paper jams occur frequently, try the following: Check all the jam locations. (See Clearing jams.) A piece of media might be stuck somewhere in the printer. Even a small torn piece of media in the printer path can cause repeated jams. Check that the trays are properly adjusted. (See Loading trays.) The guides should click into place without being too tight against the media. Check that media is correctly loaded in the trays and that the trays are not overfilled. Make sure that the stack is under the tabs and below the maximum-height indicators. See Loading trays. Check that all trays and paper-handling accessories are completely inserted into the printer. (If a tray is opened during a print job, this might cause a jam.) Check that all covers and doors are closed. (If a cover or door is opened during a print job, this might cause a jam.) Try printing to a different output bin. (See Understanding media output options.) The sheets might be sticking together. Try bending the stack to separate each sheet. Do not fan the stack. If you are printing from tray 1, try reducing the size of the stack. If you are printing from the optional envelope feeder, make sure that it is loaded correctly (with the bottom envelopes in slightly farther than the top envelopes). (See Loading envelopes in the optional envelope feeder.) If you are printing small sizes, feed the media with the short-edge first. (See Guidelines for custom-size paper.) Turn over the stack of media in the tray. Also try rotating the paper 180 degrees. Check the characteristics of the paper or other print media that you are using. Use only media that meets HP specifications. (See Paper specifications.) Try using different media to see if the problem goes away. Do not use curled, deformed, damaged, or irregular media. Check that the environmental conditions for the printer are met. (See Operating environment.) Avoid using paper that has already been used in a printer or copier. Try using paper from a freshly opened ream.

Problems with Mac OS 9.x (continued)
A print job was not sent to the printer that you wanted. Cause The print queue might be stopped. The wrong printer name or IP address is being used.
