Setting The Resolution And Density - Canon B155 User Manual

Setting the resolution and density

You can control the resolution and density of the fax reproduction when sending or copying documents.
j What is resolution
Resolution defines the quality of the document reproduction. STANDARD is enough for most text
documents. Documents with very fine print should be set to FINE. Documents with photographs should
be set to PHOTO.
j Setting the resolution
To set the resolution, you need to load the document first
(see p. 49).
¶ STANDARD
Press [Resolution] until STANDARD appears.
Standard resolution is 3.85 lines/mm.
When copying, even if you set STANDARD, the
document will automatically be scanned in FINE mode.
¶ FINE
Press [Resolution] until FINE appears.
Fine resolution is 7.71 lines/mm.
¶ PHOTO
Press [Resolution] until PHOTO appears.
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.
j Density 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.
