(Printing assurance 1)
• 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.
