Managing HP LaserJet toner cartridges
It is recommended that you use HP LaserJet toner cartridges. HP has
designed the HP LaserJet 3100 product, toner cartridge, and toner
formula to work together to give you optimal image quality and
reliability from your HP LaserJet 3100 product. To order an HP
LaserJet toner cartridge, see “Ordering parts” in chapter 9.
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 “Printing faxes received to memory” in chapter 3 for
instructions on attempting to reprint.
