When copying documents from the ADF or with the ADF or document glass cover firmly closed, the function becomes disabled.
When the function is enabled, manually adjust the background removal. The Auto Background Removal function is disabled. When Background Removal is set to Auto, Level 3 is applied.
When copying documents with slashes or of complicated shapes, documents and outside documents may not be correctly detected.
Do not use the function under a light. Shadows may not be erased successfully.
Widely open the ADF or document glass cover.
If the ADF or document glass cover opens insufficiently, documents and outside documents may not be correctly detected.
Strong light is emitted while copying. Do not look straight the document glass surface.
If there are any problems with the standard level (3), adjust the criteria in the following steps.
If the outside of the document is not erased, increase the value on the criteria.
If dark parts inside the document are erased, decrease the value on the criteria.
