Print quality problems
If the printout is unsatisfactory, consider the following suggestions:
❚ Most paper has a right side and a wrong side. If the print quality is poor, try
turning the paper over and printing on the other side.
❚ If characters and images are blurred, check that you are using the correct
kind of paper, see p. 6.
❚ If ink gets on the printer’s platen, the reverse side of the printed page will
have smudges. In this case, clean the platen area with a soft dry cloth.
See p. 89.
❚ If white streaks or missing dots appear on printed pages, perform the print
head cleaning operation. See p. 90.
❚ If the quality is not crisp and clear after cleaning the print head, repeat the
head cleaning procedure again. If output is still not satisfactory after clean-
ing the print head five consecutive times, replace the BJ cartridge. See p. 91.
