Print cartridge storage Do not remove the print cartridge from its package until you are ready to use it. Always store the print cartridge in the proper environment. The storage temperature should be between -20°C and 40°C (-4°F to 104°F). The relative humidity should be between 10% and 90%. CAUTION: To prevent damage to the print cartridge, do not expose it to light for more than a few minutes. Print cartridge life expectancy The life of the print cartridge depends on the amount of toner that print jobs require and the length of life for the components inside the cartridge. When printing text at approximately 5% coverage (typical for a business letter), the HP print cartridge lasts an average of 12,000 pages. The page-yield specification that HP provides is a general guideline. Actual yield can vary according to usage conditions. At any time, you can verify life expectancy by checking the supply level, as described below. Checking the supply level Check the supply (toner) level by using the product control panel, embedded Web server, or HP Web Jetadmin, or by printing a supplies status page. Using the product control panel 1. From the Home screen, touch Administration. 2. Touch Information. 3. Touch Configuration/Status Pages. 4. Touch Supplies Status Page. 5. Touch Print. NOTE: If you are using non-HP supplies, the supplies status page might not show the remaining life for those supplies. Using the embedded Web server 1. In a browser, enter the IP address for the MFP home page. This goes to the MFP status page. 2. On the left side of the screen, click Supplies Status. This goes to the supplies status page, which provides print cartridge information. Using HP Web Jetadmin In HP Web Jetadmin, select the MFP. The device status page shows print cartridge information.
