TROUBLESHOOTING AND ROUTINE MAINTENANCE 14 - 24 Replacing the toner cartridge The DCP can print up to 6,700 pages using a high yield toner cartridge. When the toner cartridge is running low, the LCD shows Toner Low. The DCP is supplied with a standard toner cartridge that must be replaced after approximately 3,500 pages. Actual page count will vary depending on your average type of original (i.e., standard letter, detailed graphics). Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. Be sure to seal the toner cartridge tightly so toner powder does not spill out of the cartridge. If you have questions, call your local waste disposal office. We recommend that you clean the DCP when you replace the toner cartridge. It is a good idea to keep a new toner cartridge ready for use when you see the Toner Low warning.
