CHAPTER 6 MAINTENANCE CHAPTER 6 MAINTENANCE MAINTENANCE Toner Cartridge A new toner cartridge contains enough toner to print approximately 6,000 A4/Letter-size single-sided pages at about 5% coverage (if the print density is set at level 8). You can check the current page count or the number of printed pages with the MODE switch (PAGE COUNTER). For further information, see "MODE Switch" in Chapter 4.  Notes Toner consumption varies according to the image coverage on the page and the print density setting. • The greater the image coverage, the greater the toner consumption. • If you change the print density setting for lighter or darker printing, toner consumption varies accordingly. To adjust print density setting, see "Checking the Printed Test Pattern or Demo Page" in Chapter 2. Toner Empty Message Check printed pages, page counter, and display messages periodically. If the display shows the following message, the printer has almost run out of toner or the toner is not evenly distributed inside the cartridge. 16 TONER EMPTY Although you can print between 30 and 100 additional pages after the toner empty message first appears, be sure to replace the toner cartridge with a new one before it becomes completely empty. You can select the printer's action when the "TONER EMPTY" message appears, whether to stop or continue printing. See "ADVANCED MODE" in Chapter 4. 6-1
