11. Appendix
Notes About the Toner
• Proper operation cannot be guaranteed if any third-party toner is used.
• Depending on printing conditions, there are cases where the printer cannot print the number of
sheets indicated in the specifications.
• When operating the machine for the first time, use the print cartridge supplied with this machine. If
this cartridge is not initially used, the following problems may occur:
• "Replacement Required: Print Cartridge" will be displayed before the toner runs out.
• "Replacement Required: Print Cartridge" will not be displayed when the toner runs out, but
instead the printed image suddenly becomes pale or blurred.
• To continue printing after "Replacement Required: Print Cartridge" is displayed, set [Toner End
Option] to [Continue Printing]. However, since any trouble caused by using this setup is outside of
the scope of the manufacturer's warranty, this setup should be used with care. For details about
[Toner End Option], see page 143 "System Settings".
• If [Toner End Option] is first set to [Continue Printing] and then to [Stop Printing], be sure to use a
new print cartridge. If a used print cartridge is installed, there will be a discrepancy between the
remaining toner level displayed and the actual remaining toner, and accordingly, "Replacement
Required: Print Cartridge" will not be displayed at the appropriate timing.
• The lifetime of the photo conductor, which is built into the print cartridge, is taken into account in
displaying "Replacement Required: Print Cartridge". If the photo conductor stops working before
the toner runs out, "Replacement Required: Print Cartridge" may be displayed.
