SUBJECT: TONER SCATTERING
SYMPTOMS:
1. Toner scattering in the rear of the machine
2. Toner scattering from the filters of the toner hopper
CAUSES:
1. Toner Scattering In The Rear Of The Machine
a) Poor shielding at the connecting area between drum cleaning unit and toner recycling case.
b) The opening in the toner recycling case that joins with the toner collection pipe of the transfer unit is
not an airtight connection.
2. TONER SCATTERING FROM THE FILTERS OF THE TONER HOPPER
a) Poor shielding at the connecting area between the cylinder case and the toner transport coil tube.
b) Toner clogs occur in the tube located between the toner hopper and the cylinder case.
SOLUTIONS:
IMPORTANT: Check the following items before performing the solution below.
1. Check the toner filter [A] and drum filter [B], and clean or replace them as necessary.
NOTE: The toner filter should be replaced every 350k (B070/B071).
The above cleaning/replacements are also effective in maintaining proper machine internal temperature,
which is key in minimizing scattering since slight rises in temperature can cause scattering to occur more
easily.
GENERAL:
2. If toner scattering still occurs, clean the toner transport path.
