[Correct Blurry Image]
[Menu] [Adjustment/Maintenance]
Depending on the paper type or the usage environment of the machine, there may be blurry stains on the printed
paper. If so, specifying this setting may improve the situation. First, specifying [Mode 1] may correct the problem. If
this does not correct the problem, select [Mode 2], [Mode 3], and [Mode 4] in that order.
* When this setting is enabled, the print density may decrease or the print speed may be slower.
