• 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.
• Selectors 5 and 6: Assurance print 1 and 2
Enabling assurance print 1 or 2 causes the machine to mix black ink (pigment-based) and a
little of cyan ink (dye-based) to use in monochrome copy or in monochrome FAX reception
and list output, respectively.
If black ink is not jetted out normally, cyan ink can be substituted for black ink in printing.
This ensures that in list printing (in which data once printed will be deleted) the data will be
preserved as a printout.
• Selectors 7 and 8: Workaround for false jam detection (Functional restriction on the paper width
sensor)
The setting made by these selectors applies to the list and index printing and test printing.
When logo printed recording paper is used, for example, the paper width sensor might
misdetect the paper present state as "no paper loaded" due to the logo's color. Limiting the
paper width sensor functions with these selectors avoids detecting such a false paper jam.
