Waste Toner Container Detection
Presence/absence of the Waste Toner Container is detected.
Detection timing
1) At power-on
Detection description
Presence/absence of the Waste Toner Container is detected according to the status of the
Waste Toner Container Switch (SW2).
ON: There is a Waste Toner Container
OFF: There is no Waste Toner Container (display user message)
Sensor Flag
[Without the container]
[With the container]

Special Controls
This machine has the following sequences as the special sequence.
Solid black band
Solid color band (Y/M/C/BK)
Black Band Sequence
Image Smear Prevention
Sequence
Solid color band (Y/M/C/BK)
Developing Discharge
Sequence
Black Band Sequence
Control timing: At last rotation after printing of 100 sheets
When performing continuous printing while no toner is fed to the ITB Cleaning Blade, it may
cause the blade to be everted. To prevent it happens, toner is transferred onto the ITB (a
solid black band: width = whole ITB width, length = 1mm) to supply toner to the blade.
Image Smear Prevention Sequence
Control timing: Immediately after generating patch pattern with ATR control under a high
humidity environment.
Toner band for all colors is formed to prevent image smear by supplying toner to the
Auxiliary Brush and increasing sweeping performance for discharged product on the Drum.
Developing Discharge Sequence
Control timing: When the average image ratio per sheet reaches 2% or less
Developing performance can decrease when performing continuous printing with low image
ratio. To prevent this error, the average image ratio for each color is calculated with the ATR
control and adequate amount of toner based on the calculation (width = A4, length = a solid
color band according to the deteriorated toner amount) is transferred to the ITB.
Print Mode Switch Sequence
This sequence is executed when the print mode to be printed next is different from the print
mode currently executed. For this sequence, the operation to be executed differs between
color mode switching and print speed switching. Therefore, downtime differs as well. Up to
28 seconds downtime is expected.
Type
Control to execute switching
Color mode switching
(Color mode, Black mode)
• Drum phase control (when the print mode to be printed next is
the color only)
Print speed switching
(Full-speed, Half-speed)
• Fixing temperature switching
• Scanner Motor / Feed Motor speed switching
• Drum phase control (when the print mode is the color only)
