Dust detection correction control (continuous lines)

This control detects and corrects lines caused by dust that has been detected between sheets.

Correction is performed symmetrically for lines (caused by dust) detected by scanning glass dust detection.

In the case of detecting lines caused by specified amount of dust, an alarm is displayed to encourage cleaning.

For difference from noncontinuous lines, see the Dust detection correction control (noncontinuous lines).
