Setting of Bk-toner band density at stop
To set the density of toner band to be formed on the Photosensitive Drum for Bk-color while drive
is stopped.
While drive is stopped, the Photosensitive Drum for Bk-color is in contact with the ITB. If the contact
state remains, the coating agent of the ITB penetrates to the surface, causing no toner deposit on
the contact area of the drum. As the result, white lines appear on Bk-color image at intervals of
drum circumference (94 mm). The newer the ITB is, the more likely the component penetrates.
Therefore, toner band is formed on the contact area of the drum and the ITB while drive is stopped
until the number of sheets set in ZAB-TH is fed.
Increase the value when white lines appear. Because toner band becomes darker, white lines can
be alleviated, but soiled back of paper with Bk-toner may occur.
- When white lines appear on Bk-color image at 94 mm intervals
- When soiled back of paper with Bk-color occurs
Enter the setting value (switch negative/positive by -/+ key) and press OK key.
- If the value is too small, white lines appear. If the value is too large, soiled back of paper occurs.
- Be sure to change the value back to the default when replacing the ITB.

When the value of TR-BLT (ITB parts counter) is larger than the number of sheets specified in
ZAB-TH, toner band is not formed so setting result cannot be checked.

Setting of coated paper pickup timing
To set whether to pick up coated paper before or after the start of image formation.
Usually, before the start of image formation, a paper is picked up and fed to the position where it
is in contact with the Pre-registration Roller and stays there.
Set 1 when trace of roller appears on the image on coated paper. Image failure can be alleviated,
but productivity is decreased because the 1st sheet of paper is picked up after the start of image
formation.
When trace of roller appears on the leading edge (76 mm) of coated paper
Enter the setting value, and then press OK key.
When 1 is set, productivity is decreased.
