The number of pages you can print with one toner cartridge varies 
depending on the type of documents you usually receive or copy. A toner 
cartridge will print about 2500 pages/A4 size of standard business 
communications at a typical print coverage of 4% (equivalent of CCITT 
No. 1 test chart). The first toner cartridge installed in a new image drum 
unit will have a decreased yield because the image drum unit itself has to 
be filled. 

If your fax machine displays TONER LOW or REPLACE TONER 
CART., replace the toner cartridge with a new one. However, if the print 
density is high enough, you can continue to use the toner cartridge without 
replacing it until the print density becomes too low.
