Solutions
Moiré patterns, such as bands, checks or stripes in the picture after it
is copied, are caused by copying a picture of poor quality, such as a
newspaper photo. To reduce moiré patterns, try placing the picture at
an angle on the glass. Or try placing one or more clear plastic sheet
protectors directly on the glass, and then place the original face down
on top of the plastic sheet. You can also try reducing the copy by 3%.
To reduce or enlarge copies in 1% increments, press and hold down
the Reduce/Enlarge button and then press the Plus (+) and Minus (–)
buttons. To confirm the setting, press Select/Resume.
If you are using special papers, such as glossy, premium, or
transparencies, make sure the Paper Type you selected reflects the type
of paper in the bottom tray. Press the Paper Type button until the
correct paper type appears in the display and press Select/Resume.
Print a self test page by pressing the Menu button until Self Test Page
appears on the display. Press the Select/Resume button to print the
self test page.
If any of the colored bars are missing (cyan, magenta, yellow, or
black), the appropriate print cartridge must be replaced. If streaks or
white lines appear in any of the colored bars, the cartridges need to
be cleared.
Follow the cartridge clearing instructions later in this chapter.
Banding can sometimes be improved by setting Best quality on the
front panel.
