field case, A4-size cassette was selected) > register the paper type as "thin paper"], and register the paper source as one of the options for auto paper selection
functions; then make a copy of A4-size original from the copyboard glass, the registered paper source was not selected in the auto paper selection.
Cause
Thin paper (about 94g to 79g/square meter) is out of specification for the auto paper selection function (as of June 9, 2006).
Taking consistency with other models into consideration, a software modification will be considered so that thin paper can be available for the auto paper
selection function (scheduled in the beginning 2007).
