• Selector 1: Prevention of stains on back side of leading edge of paper in borderless printing
Setting this selector to "1" reduces the protruding amount of the leading edge of
recording paper to the platen groove to minimize stains that could be caused by ink
mist on the back side of the leading edge. Enabling this function reduces the
throughput than disabling it.
• Selectors 3 and 4: Protection of platen from no-paper printing to prevent stains (Functional
restriction on the paper width sensor)
The setting made by these selectors applies to such printing that is assumed to be
at a high resolution, that is, printing from a PC or memory card, copying, and
printing via PictBridge.
If these selectors are set to "0, 0," the machine automatically determines the
functions of the paper width sensor depending upon the print resolution selected.
Therefore, in low resolution printing, e.g. when the "Fast" print quality is selected,
the paper width sensor is automatically disabled. On the contrary, in high resolution
printing, e.g. when the "Highest" print quality is selected, the sensor is
automatically enabled.
Setting these selectors to "1, 1" disables the paper width sensor to save the
sensing time for higher throughput.
