Media Selection Guidelines
NOTE More detailed specifications are in the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801 (See "Related Documentation and Training Media" later in this chapter).

Paper
To achieve the best possible print quality and avoid paper jams, follow these guidelines for selecting paper:

· Use only copier grade paper that meets all specifications in the paper
specification guide. Avoid paper with embossed lettering, perforations, or texture that is too smooth or too rough. · Colored paper should be of the same high quality as white photocopy paper. The pigments must withstand the fusing temperature of 392° F (200° C) for 0.1 second without deterioration. Do not use paper with a colored coating that was added after the paper was produced. · Pre-printed forms must be printed with non-flammable, heat-resistant inks that do not melt, vaporize, or release hazardous emissions when subjected to the fusing temperature of 392° F (200° C) for 0.1 second. · A small sample of a new print media should be tested before purchasing large quantities.

Envelopes
CAUTION To prevent severe printer damage, do not use envelopes having windows, clasps, snaps, or synthetic materials. Envelopes can be printed only from the MP Tray. Choose envelopes that are well-constructed. They should lay flat and be sharply creased. They should not be wrinkled, nicked, or otherwise damaged. Envelope adhesive must be compatible with the heat and pressure of the fusing process.

1-8 Product Information

Adhesive Labels
Product 1 Information Use the following guidelines when selecting labels: CAUTION This printer does not support use of labels with any exposed spaces. Previous LaserJet family printers could safely print on label stock with exposed spaces running lengthwise down the sheet. Do not attempt to print on label sheets after any of the labels have been removed from the sheet. Damage to the printer may result.

· Labels must be arranged on the carrier sheet so that there are no exposed
spaces on the sheet. Using label stock with spaces between rows or columns of labels can often result in labels peeling off during printing, causing serious jamming and possible printer damage. · The top sheet (printing surface) must be of copier quality and provide good toner adhesion. · The carrier sheet (backing sheet) must be compatible with the temperatures and pressure of the fusing process, and must be coated for easy release of the top sheet. · The adhesive must be stable at the 392° F (200° C) temperatures encountered for 0.1 second in the fusing process, and must not produce emissions that exceed exposure levels or threshold limits established by OSHA and other safety agencies. Adhesives must not come into direct contact with any part of the printer. NOTE The MP Tray is recommended for printing adhesive labels. A wide selection of suitable labels is available through Hewlett-Packard. A list of available sizes is located in the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801.

Transparencies
Overhead transparencies used in HP LaserJet printers must be able to withstand the 392° F (200° C) temperatures encountered in the printer's fusing process for 0.1 second. Suitable transparency film is available through Hewlett-Packard. Refer to the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801 for details. NOTE The MP Tray is recommended for printing transparencies.

Product Information 1-9

Storing Print Media
Follow these guidelines when stacking and storing print media:

· Store paper in its ream wrapper until ready to use. · DO NOT store cartons or reams directly on the floor where they will absorb
a higher moisture content. Instead, place cartons on a pallet or on shelves.

· DO NOT store individual reams in a manner that causes them to curl or
warp along the edges.

· Re-wrap partially used packages of media before storing. · DO NOT stack more than six cartons on top of each other. · Stack each carton upright and squarely on top of the one underneath. · DO NOT place anything on top of media, regardless of whether the paper is
packaged or unpackaged.

· Store envelopes in a protective box to avoid damaging the envelope edges. · Keep stored media away from temperature and humidity extremes. · DO NOT store printed documents in vinyl folders (which may contain
plasticizers) or expose the documents to petroleum based solvents.

Shipping Print Media
When shipping print media through different environments, plastic wrap all cartons on the shipping pallet. When shipping media across bodies of water, wrap individual cartons as well. Packaging must protect the media from physical damage.

Service Approach
Repair of the printer normally begins with use of the printer's internal diagnostics in conjunction with the troubleshooting procedures in Chapter 7. Once a faulty part is located, repair is generally accomplished by assembly level replacement of Field Replaceable Units (FRUs). Some mechanical assemblies may be repaired at the subassembly level. PCA component replacement is not supported by Hewlett-Packard.

Ordering Parts
Field replaceable part numbers are found in Chapter 8 of this manual. Replacement parts may be ordered from HP's Service Materials Organization (SMO), or Support Materials Europe (SME).

Phone numbers for the various sources are:
· SMO (Service Materials Organization)
1-800-227-8164 (U.S. only)

· SME (Support Materials Europe)
(49 7031) 142253

· HP's Distribution Center (HPD)
1-303-353-7650

Exchange Program
HP offers remanufactured assemblies for some parts. These are identified in Chapter 8 and can be ordered through Parts Direct Ordering (PDO), or Support Materials Europe (SME).

Consumables
The printer has no consumables other than the toner cartridge, which may be ordered directly from Hewlett-Packard. Refer to Chapter 8 for ordering information.

1-16 Product Information

Toner Cartridge Life
Product 1 Information The toner cartridge (C3900A) is designed to simplify replacement of the major "consumable" parts. The toner cartridge contains the printing mechanism and a supply of toner. At 5% page coverage, a toner cartridge will print approximately 7500 pages (see Figure 1-7). Figure 1-7

Sample 5% Page Coverage When regularly printing pages with less coverage, such as short memos, a toner cartridge should print more than 7500 pages. However, the cartridge may print less than 7500 pages if routinely printing very dense print. NOTE For best results, always use a toner cartridge before the expiration date stamped on the toner cartridge box.

Product Information 1-17

Refilled Toner Cartridges
While Hewlett-Packard does not prohibit the use of refilled toner cartridges during the warranty period or while under a maintenance contract, their use is not recommended for the following reasons:

· Repairs resulting from the use of refilled toner cartridges are not covered
under the Hewlett-Packard warranty or maintenance contract.

· Hewlett-Packard has no control or process to ensure that a refilled toner
cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also cannot predict what the long term reliability effect on the printer is from using different toner formulations found in refilled cartridges.

· The print quality of HP LaserJet toner cartridges influences the customer's
perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled toner cartridge.

Recycling Toner Cartridges
In order to reduce waste, Hewlett-Packard utilizes a recycling program for used toner cartridges. Cartridge components that do not wear out are recycled. Plastics and other materials are recycled. Hewlett-Packard pays the shipping costs from the user to the recycling plant. For each cartridge returned, HP donates one U.S. dollar to be shared by the Nature Conservancy and the National Wildlife Federation. To join this recycling effort, follow the instructions inside the toner cartridge box.

Job Menu
The items available in the Job Menu can also be changed through software applications if an appropriate printer driver is installed. Table 3-7 Item RESOLUTION PERSONALTY Job Menu Items Options 300 or 600* AUTO* PCL PS Explanation For most purposes, 600 dpi is recommended.

Personality means printer language. The printer can switch from its standard personality, PCL, to other personalities, such as PostScript. When PERSONALTY is set to AUTO, the printer analyzes each print job it receives and switches personalities automatically.
When you make another personality the default, the printer stops switching personalities automatically unless a software command specifically instructs it to do so. If the PostScript option is not installed, PERSONALTY will not display in the Job Menu. If you select PS as the default, you may want to set ADV FNCTNS in the Parallel Menu to OFF.

PWRSAVE

OFF, 15 MIN, 30 MIN*, 1 HR, 2 HRS, 3 HRS

Sets the amount of time the printer is idle before the fuser shuts down. The printer automatically starts warming the fuser when you send a print job to the printer, press a control panel key, load or remove paper, or open the top door. NOTE: A ten second interval is also available in Service Mode (see "Service Mode" later in this chapter). I/O timeout refers to the time, measured in seconds, that the printer waits before ending an incomplete print job (it scrolls in increments of 10). This setting allows you to adjust timeout for best performance. If data from other ports appears in the middle of the print job, increase the timeout value. You will not see this item unless the error 21 PRINT OVERRUN has occurred. (See Chapter 7 for error message troubleshooting.)

Configuration Menu
Configuration Menu items cannot be changed from software applications. Table 3-8 Item MP TRAY Configuration Menu Items Options FIRST* CASS Explanation Draws paper from the MP Tray regardless of paper size (this setting not recommended for shared environments). The MP Tray operates as a paper cassette. Paper feeds automatically. Paper size must be selected with the [MP[Paper]Size] key because the MP Tray cannot sense the size of the paper. The [MP [Paper] Size] key works only when the MP Tray is set to CASS. Operates only as a manual feed tray. Locks out a tray or a combination of trays so the printer will not draw paper. Lock-out options depend on how the MP Tray is configured and whether an optional 500-sheet Lower Cassette (LC) is installed. When the MP Tray = MANUAL or FIRST or no optional Lower Cassette is installed, no paper sources are available to be locked out. All possible options are: NONE MP PC LC PC MP LC MP LC PC CLR WARN ON* JOB AUTO CONT ON* OFF LOW TONER CONT* STOP

Printer stops and goes offline until operator changes the toner cartridge, presses [On Line], or [Continue].

Operating Overview 3-11

Memory Configuration Menu
This menu contains the items for personality Resource Saving and I/O Buffering. Depending on how the printer memory is configured, any combination of menu items and possible values can appear. When you change an item in this menu, the printer automatically resets, and all fonts, macros and downloaded data in the printer are lost (except data stored on the optional Disk Accessory). Memory Configuration Menu items can be selected only from the printer control panel. Table 3-9 Item IO BUFFER Memory Configuration Items Options AUTO* OFF** ON IO SIZE 10K and up Explanation The I/O buffer is a portion of the printer memory set aside to hold incoming data. When this item is set to AUTO, the memory set aside for I/O buffering is automatically determined by the printer based on available memory. When it is set to ON, the size can be manually adjusted. When it is set to OFF, no memory is set aside. When IO BUFFER is set to ON, I/O SIZE appears in the menu. Use this item to add or reduce I/O buffer memory in increments of 10 KBytes up to 100 KBytes, then in 100 KByte increments. This item appears when a certain amount of memory and a personality SIMM are installed in the printer. If it is set to AUTO, the printer automatically determines the amount of memory to allocate to installed personalities (languages). When it is set to ON, additional memory management item selections appear for each installed personality (see next item). When it is set to OFF, no memory is allocated and personality-dependent resources (such as fonts) are lost when personality changes. When Resource Saving is set to ON, each installed personality (for example, PCL and PostScript) is added as a menu item. You can increase memory in increments of 100 KBytes up to the maximum.

Parallel Menu
Parallel Menu items can be selected only from the printer control panel. You cannot change or override them from your software application. Table 3-10 Item HIGH SPEED Parallel Menu Items Options YES* NO Explanation The speed at which data is transmitted to the printer. YES sets the Bi-Tronics parallel interface to run at a higher data rate supported by newer computers. NO sets the Bi-Tronics parallel interface to run at a slower speed compatible with older computers. Choosing ADV FNCTNS=ON enables bi-directional parallel communication, which allows the printer to send status readback messages to the computer. Setting advance functions to ON may slow personality switching.

Setting the Page Count and Serial Number
The page count and serial numbers are stored in Non-Volatile Memory. If it is necessary to replace the Formatter PCA, the page count should be set to the current value to reflect the age of the print engine. The procedure for setting the serial number is similar to setting the page count. Use the following procedure to set the page count: Before removing the old Formatter PCA, print a control panel self test to verify the current page count and serial number of the printer, if possible. NOTE If it is not possible to print a self test, try to verify the values before replacing the Formatter PCA by following steps 3 through 5, below. After verifying the page count from the old Formatter PCA, replace it with the new PCA as described in Chapter 6.
