Toner end recovery
The copier enters the recovery process in the following cases:
1. The front door is opened and a toner cartridge is removed or inserted.
This is regarded as an ordinary replacement procedure for the toner cartridge.
•
When the door is opened, the copier moves the next-to-be-replaced color
toner cartridge to the replacement position.

•
Replace the toner cartridge.

•
The copier enters the toner replenishment confirmation mode after the toner
cartridge is replaced.
NOTE: If recovery is needed for two colors, the copier proceeds with the next
color if the door is opened or if the user specifies at the operation panel
that the first color should be skipped.
2. If the copier is turned off and on, it assumes that toner cartridges for all colors
have been replaced and enters the toner replenishment confirmation mode for
all colors.
Toner replenishment confirmation mode
1. For color toners, the copier moves the toner cartridge of the first color to be
subject to toner replenishment confirmation to the toner end sensor detection
position (K, then Y, then C, then M). The copier does not use the toner end
sensor for the K toner (it uses V
SP
). However, it moves the revolver to the toner
end sensor when confirming toner replenishment for the K toner.
2. The copier rotates the toner cartridge for a certain period.
3. The machine checks whether toner is present. For the C, M, and Y toners, the
copier uses the toner end sensor. For the K toner, the copier measures V
SP
.
4. The copier moves the toner cartridge for the next color to the toner end sensor
detection position and performs steps 2) and 3).
5. When the toner replenishment confirmation cycle ends, the copier moves the
toner cartridges to the detection position for the toner end sensor. The copier
then checks again whether toner is present. If toner is found to be not present,
the copier returns that cartridge to what it was before the toner recovery
procedure started (toner near end or toner end).
6. The copier resets the toner near end and toner end states and resets the toner
end related counters (pixel and sheet counters)for cartridges which the
machine detects to be full.
Toner replenishment confirmation mode takes several seconds for the C, M, and Y
toners and 20 to 30 seconds for the K toner.
