CHAPTER 5 PERIODIC MAINTENANCE
NOTE:
*There are many factors that determine the actual toner life, such as temperature, humidity,
type of paper that you use, the number of pages per print job, etc.
*The amount of toner used varies according to what is printed on the page and the print
density setting.
*The more that is printed, the more toner will be used.
*If you change the print density setting for lighter or darker printing, the amount of toner that is
used will change.
*Wait to unpack the toner cartridge until immediately before you install it in the printer.
