Always store toner cartridges on their side with the top side up. • If a toner cartridge other than a SHARP-recommended toner cartridge is used, the machine may not attain full quality and performance and there is a risk of damage to the machine. Be sure to use a SHARP-recommended toner cartridge. • Keep the used toner cartridge in a plastic bag (do not discard it). Your service technician will collect the used toner cartridge. • To view the approximate amount of toner remaining, continually touch the [COPY] key during printing or when the machine is idle. The percentage of toner remaining will appear in the display while the key is touched.
