5. Incorrect stacking.
Too many sheets of paper in the output tray.
The output tray capacity depends on the type of paper
and print coverage on the page. It will hold
approximately 60 standard weight printed pages.
Heavily printed pages tend to curl and may not stack
correctly. They may also stain the rear of the page
stacked over them, as they require longer to dry. Always
remove such pages from the output tray as soon as they
are expelled from the printer.

Print heads

When changing the print head(s), take care not to
touch the print head carriage shaft nor the area
under the print head carriage.
1. Printer does not print
Check that you have removed the protective film from
the print head.
2. Print head carriage does not return to the rest
position after a replacement operation.
Check that you have inserted the print head properly, in
the correct position (black, left; color/Photo, right).
Check that nothing is blocking the carriage path.
Check that the print head(s) is/are fixed correctly.
If you have inserted a NEW print head or if you have
replaced the ink cartridge, remember to reset the ink
counter (press and hold PAPER and then press POWER
for at least 2 seconds).
3. Characters are faint.
Run a demo page to check that there is ink in the print
head.
If printing is still faint, clear the print head, holding ON
LINE and pressing PAPER for at least 2 seconds.
Repeat the demo page; if there is no improvement,
replace/change the ink cartridge/ print head.
