You can control the resolution and density of the fax reproduction when sending or copying documents.

jWhat is resolution

Resolution de®nes the quality of the document reproduction. STANDARD is enough for most text documents. Documents with very ®ne print should be set to FINE. Documents with photographs should be set to PHOTO.

To scan documents that contain photos, use the PHOTO setting. With this setting, areas of the document that contain photos are automatically scanned with 64 levels of grey, rather than just 2 levels, black and white. Photo resolution is 3.85 lines/mm. This results in a much better reproduction of the photograph.

jDensity control

You can adjust the scanning density by changing the DENSITY CONTROL setting in the USER SETTINGS (see p. 85). For light originals choose the DARKER setting. For dark originals choose the LIGHTER setting.
