Drum Error - The corona wire on the drum unit needs to be cleaned.
Clean the corona wire on the drum unit. (See Cleaning the corona wire on page 122.)
Cleaning the corona wire: If you have print quality problems, clean the
corona wire as follows:
a. Turn off the machine's power switch.
Unplug the telephone line cord first, disconnect all cables, and then unplug
the power cord from the AC power outlet.
b. Open the front cover.
c. Slowly take out the drum unit and toner cartridge assembly.
CAUTION: We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.
d. Clean the corona wire inside the drum unit by gently sliding the green tab from right to left and left to right several times.
CAUTION: Be sure to return the green tab to the home position (a) (1). If you do not, printed pages may have a vertical stripe.
e. Put the drum unit and toner cartridge assembly back in the machine.
f. Close the front cover.
g. Plug the machine's power cord back into the AC power outlet first, and then reconnect all cables and telephone line cord. Turn on the machine's power switch.
