Toner Near-end/End Detection
If Vt level 6 is detected 5 consecutive times, near-
end is detected.
Toner is supplied after the copy job:
If supply recovers to Vt level 5, near-end is
cancelled.
Otherwise, toner end occurs after 50 copies
If Vt level 7 is detected 3 consecutive times, toner
end is detected immediately.
Recovery after adding new toner
The machine must recover to Vt level 5 after the
toner bottle has been replaced.
Do not practice disassembly at this time. All PCU related disassembly will be
done later after studying drum cleaning.
