Managing HP LaserJet toner cartridges
It is recommended that you use HP LaserJet toner cartridges.
HP has designed the HP LaserJet 3150 product, toner cartridge, and
toner formula to work together to give you optimal image quality and
reliability from your HP LaserJet 3150 product. To order an
HP LaserJet toner cartridge, see “Ordering parts” on page 221.
You can expect a toner cartridge to print approximately 2,500 pages
when you are printing typical business letters with text covering about
5 percent of the page. A page containing graphics uses more toner
and shortens the life of the cartridge.
It is very important to replace the toner cartridge when it is near the
end of its life, which is often indicated by areas of faded print. If the
toner runs out while faxes are being received, the faxes print as blank
pages and you may lose the faxes. You can attempt to reprint these
faxes. See “Reprinting faxes” on page 36 for instructions on
attempting to reprint.
Recycling toner cartridges
To reduce landfill waste, HP has adopted a recycling program for
empty toner cartridges. A postage-paid shipping label can be found
inside the new HP LaserJet toner cartridge box. Since 1990, the
HP LaserJet Toner Cartridge Recycling Program has collected more
than 25 million used HP LaserJet cartridges that otherwise may have
been discarded in the world’s landfills. To join this recycling effort,
follow the instructions provided in the new toner cartridge box.
