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. 7.
¶ 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. 103.
¶ If white streaks or missing dots appear on printed pages, perform the print head cleaning operation.
See p. 104.
¶ 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 cleaning the print head five consecutive times, replace the
BJ cartridge. See p. 105.
¶ If the following print quality problems occur in the entire printing area, check for the most probable
cause and remedy as listed below.
