Removing toner from Mg sleeve to prevent drum scratches
If the drum knob is not fastened completely, the PG becomes narrow and causes drum
scratches. Do the following procedure to remove toner adhered to the Mg sleeves.
Step 1. Stick packing tape against the surface of the development rollers to remove
toner.
1-1. Remove old developer from the unit.
1-2. Pull out the developer unit and remove the drum
cleaning unit and OPC drum.
1-3. Rotate the development rollers downwards
using your fingers until the developer is
completely poured out.
Note
 Be careful not to pull the top cover entrance seal
when rotating the development rollers.
 Working with hand gloves is recommended to
prevent oil on your fingers from adhering to the
rollers. Make sure to thoroughly wash your hands
in advance if gloves are not in hand.
1-4. Stick the packing tape against the surface of the development rollers and peel off the
toner. Repeat this procedure. (Vacuuming the toner in advance will make this process
easier.)
NOTE
 Make sure the packing tape adhesives do not adhere to the development rollers.
 NEVER apply solvent to remove toner from the development rollers. Solvent will
dissolve the toner, which will then adhere to the development rollers even more
strongly.
 Make sure to completely remove toner adhered to the development rollers. Toner will
build up on toner particles remaining on the development roller.
