The backs of printed sheets are
blemished. • When removing a jammed sheet, the inside of the printer
may have become dirtied. Print several sheets until they
come out clean.
• If document size is larger than paper size, e.g. A4 docu-
ment on B5 paper, the back of the next printed sheet may
be dirtied.
If rubbed with your finger, it
smears out. The setting of the paper may not be correct. For example, al-
though thick paper is used, the setting for thick paper may
not be set.
• Check the paper settings of this printer.
See p.82 “Types of Paper and Other Media”.
• Check the paper settings of the printer driver.
See the printer driver Help.
