Here are some suggestions:

  • Specify a darker paper color, for example, change to Color Paper 1 or to Color Paper 2.
  • If the job is printed on paper of different colors, specify the darkest color.
  • If the problem occurs even with the Mode 3 setting (Color Paper 2), increase the CIS LED light intensity by following the procedure below.

Adjustments

  1. Go into the SP mode and adjust the settings of SP1916-003.
    1.00 to 5.00/3.53 (default)/0.001 Step
  2. Try Advanced Settings
    Login > Paper Setting> Edit Custom Paper > Select the paper in use > Change > Under “Advanced Settings” > Select 06 (Color Paper Edge Detection Adjustment).

  3. Do not select a value that is too high.

    • Doing so may cause jams because the CIS detects diffused reflection from the surrounding components, such as the guide plates, for example.
    • The high value could also shorten the CIS service life.
