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.

❚If the following print quality problems occur in the entire printing area, check for the most probable cause and remedy as listed below.
