Life Expectancy of Consumables
Always inspect the components listed in Table 4-1 for wear when servicing the printer. Replace these components as needed, based on printer failures or wear, not strictly on usage.

The estimated toner cartridge life is based on Letter or A4 size paper with an average of 5% toner coverage and a medium density setting. Toner cartridge life can be extended further by conserving toner using the printer's EconoMode feature.

Toner Cartridge Life
The toner cartridge has been designed to simplify the replacement of the printer's major "consumable" parts. The toner cartridge contains the printing mechanism and a supply of toner. When using a typical word-processing application, a toner cartridge will print approximately 2500 pages where the text covers about 5% of the page.
Figure 4-1

Five Percent Text Coverage

When regularly printing pages with less coverage, such as short memos, a toner cartridge should print over 2500 pages. However, if routinely printing very dense print, the cartridge will not print a full 2500 pages.
Note

For best results, always use a toner cartridge before the expiration date stamped on the toner cartridge box.

Saving Toner with EconoMode
Toner cartridge life can be extended dramatically by using the EconoMode printing feature of the printer. EconoMode uses approximately 50% less toner than normal printing. The printed page is much lighter and is adequate for printing drafts or

proofs. EconoMode can be set through your printer driver. See Chapter 3 for information.
Notes

Some software applications may refer to this as "draft mode."

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, we do not recommend their use. The reasons for this are:

· 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. · Hewlett-Packard has no control over the actual print quality of a refilled toner cartridge. The print quality of HP LaserJet toner cartridges influences the customer's perception of the printer. Repairs resulting from the use of refilled toner cartridges are not covered under the HP warranty or maintenance contract.

Recycling Toner Cartridges
In order to reduce waste, Hewlett-Packard has adopted a recycling program for used toner cartridges. Plastics and other material are recycled. Cartridge components that do not wear out are reused. HP 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.

Cleaning the Printer
To maintain the print quality, thoroughly clean the printer:

· Every time you change the toner cartridge. · After printing approximately 2,500 pages. · Whenever print quality problems occur.
Clean the outside of the printer with a lightly water-dampened cloth. Clean the inside with only a dry, lint-free cloth. Observe the warnings and cautions below.
WARNING!

Before you begin these steps, unplug the printer to avoid shock hazard. When cleaning around the front door area, avoid touching the heating element. It may be HOT. (For heating element location, see Figure 6-14.)

Cleaning Printer Components
CAUTION

To avoid permanent damage to the toner cartridge, do not use ammonia-based cleaners on or around the printer. Do not touch the transfer roller with your fingers. Contaminants on the roller can cause print quality problems.

Cleaning Spilled Toner
Defective toner cartridges can develop leaks. In addition, after a paper jam has occurred, there may be some toner remaining on the rollers and guides inside the printer. The pages that print immediately after the jam may pick up this toner. Clean spilled toner with a cloth slightly dampened in cold water. Do not touch the Transfer Roller with the damp cloth or with your fingers. Do not use a vacuum cleaner unless it is equipped with a micro-fine particle filter.
Note

If toner gets on your clothing, use cold water to remove it. Hot water sets toner stains into fabric.
