5. Replacement In addition to the maintenance procedures described on the following pages the corona charger wires in the transfer charger unit and drum cartridge should be cleaned from time to time whenever print quality problems occur To clean the charger wire in the drum cartridge raise the upper unit open the front door and pull the orange cleaner knob slowly in and out a few times This pulls a cleaning pad along the wire When the printer begins to run low on toner the toner indicator 1 comes on first flashing then staying lit steadily as the remaining toner supply dwindles Nothing is gained by waiting for the printer to run out of toner completely At the earliest convenient opportunity after the toner indicator begins flashing you should replenish the supply by installing a new toner kit To clean the transfer charger wire take the cleaning tool cleaner from the drum kit place it on the transfer charger and slide it back and forth a few times TT Oo gm om If you continue to use the printer eventually the toner supply will be exhausted and the C1 code will be displayed At this point to avoid damaging the developer the printer stops printing To continue printing you must install a new toner kit Always replace all three items in the toner kit toner cartridge waste toner bottle and fuser cleaning pad at the same time In particular if you do not replace the waste toner
