The ink may be
dry or the noz-
zles of the print-
heads may be

If the machine has not been used for a long time, print
the nozzle check pattern and perform head cleaning, if
necessary. See p.94 “Maintenance”.

Printed ink is not
dry.
Do not touch the printing surface immediately after
printing. OHP transparencies take especially long to
dry. Take out paper from the main unit tray one by one
, being careful not to touch the printed parts, and then al-
low the sheets to dry completely. See “Copy Paper”,
