Start key Slightly glossy lines in parallel of the feed direction
sometimes appear on the both ends of wider-width paper
after copying/ printing over hundreds sheets of narrower-
width paper (ex: using A3 after A4R). Specifically in the
high-density area on heavy/coated paper, cloudlike glossy
shading appears occasionally. Refreshing the fixing roller
and/or wiping the surface of the roller can improve these
symptoms.
Level: -5 to +5 (0*) The fixing roller is automatically refreshed after a certain
copies are printed. This mode provides adjustment in
refreshing frequency and time level for refreshing
operation.
Yellow, Magenta, Cyan, When 'color cast' is seen in blank area, this can be
Black: -2 to +2 (0*) corrected by color with this function.
ON/OFF* This mode may improve the output quality of halftone
images when color fading occurs at the tail end of the
image to the feeding direction.
It can be used to eliminate the tiny white grainy dots that
appear on the output paper when copying or printing
halftone images.
1 to 4 (3*) If the dark colored area follows right after the halftone
area, 'white gap' can be appeared near the border in the
halftone area. This can be improved with this function.
ON/OFF* When two-sided copying or printing is made for high
density images on coated paper, gloss unevenness that
looks like sprinkled fine sands may occur on the side that
first passes through the fixing unit.
You can use this feature to reduce the gloss unevenness.
However, it may take a few moments to output the copy or
print because it takes time for the fixing unit to cool down
after copying or printing the first side.
