CHARGE CORONA
1. Clean the corona wires with a dry cloth. Do not use sandpaper or solvent.
2. Clean the charge corona casing with water first to remove NOx based
compounds. Then clean it with alcohol if any toner still remains on the casing.
3. Clean the end block with a blower brush first to remove toner and paper dust.
Then clean with alcohol if any toner still remains.
4. Do not touch the corona wires with bare hands. Oil stains from fingers may
cause uneven image density on copies.
5. Make sure that the wires are correctly between the cleaner pads and that there
is no foreign material (iron filings, etc.) on the casing.
6. When installing new corona wires, do not bend or scratch the wire surface.
Doing so may cause uneven charge. Also be sure that the corona wires are
correctly positioned in the end blocks. (See Charge Corona Wire Replacement)
7. Clean the grid plate with a blower brush (not with a dry cloth).
8. Do not touch the charge grid plate with bare hands. Also, do not bend the
charge grid plate or make any dent in it. Doing so may cause uneven charge.
After installing new wires, reset SP2-001-1 to 2-001-6 (corona voltage and current)
to the defaults. Then do SP2-962 (process control initialization).
