  • Page 34 ADF - Technology > Adjustment > Scanner Unit > Dust Detection Control 5-15 ● Scanning glass dust detection control DADF driver PCB In the case of 2-side scanning with this equipment, dust and smudges on the scanning glass (attached when scanning the back side) can cause lines on the image. To prevent this symptom, there is a dust detection correcting function with this equipment.
  • Page 35 ADF - Technology > Adjustment > Scanner Unit > Dust Detection Control 5-16 ● 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.
