f Put the new toner cartridge firmly into the drum unit until you hear it lock into place. If you put it in correctly, the lock lever will lift automatically. Troubleshooting and routine maintenance h Put the drum unit and toner cartridge assembly back in the machine. C Note Make sure that you put in the toner cartridge correctly or it may separate from the drum unit. g Clean the corona wire of the drum unit by gently sliding the blue tab from right to left and left to right several times. 1 Note Be sure to return the blue tab to the home position (a) (1). If you do not, printed pages may have a vertical stripe. i Close the front cover. Note DO NOT turn off the machine or open the front cover until the LCD returns to the standby state. Replacing the drum unit C The machine uses a drum unit to create print images on paper. If the LCD shows Replace Parts Drum, the drum unit is near the end of its life and it is time to buy a new one. Even if the LCD shows Replace Parts Drum, you may be able to continue printing without having to replace the drum unit for a while. However, if there is a noticeable deterioration in the output print quality (even before Replace Parts Drum appears), then the drum unit should be replaced. You should clean the machine when you replace the drum unit. (See Cleaning the laser scanner window on page 138.) IMPORTANT While removing the drum unit, handle it carefully because it may contain toner. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once. 145
