ITB
Sequence for black band
In the case of continuous prints while no toner is fed to the ITB cleaning blade, the ITB
cleaning blade can be removed. Therefore, toner (width = full width of ITB, length = 1mm
solid black band) is transferred on the ITB to supply toner to the ITB cleaning blade.
<Execution timing>
At post-rotation after the total reaches 100 prints
Sequence for transparency black band
When resistance adjustment agent on the transparency is attached on the ITB, it reduces
transfer efficiency on the attached area. If considerable amount of resistance adjustment
agent is attached on the ITB, it can cause fusion in the ITB cleaning assembly. To prevent this
symptom, toner (width = full width of ITB, length = 80mm solid black band) is supplied to the
ITB cleaning blade.
<Execution timing>
Sheet-to-sheet interval after 15 sheets of transparency are printed continuously
At post-rotation after 7 sheets are printed continuously since the last execution
Sequence for color band
Making prints with low image ratio can deteriorate toner and reduces developing performance.
To prevent this symptom, average image ratio for each color is calculated by ATR control and
appropriate amount of toner (width = A4, length = solid color band appropriate for deteriorated
toner amount) determined by the calculation is transferred to the ITB.
<Execution timing>
When average image ratio per sheet is 2% or less
