Cannot Solve Printing or Copying Problems
Try the following problems in order starting at the top until you solve the problem.
❏ Make sure you match the paper type loaded in the printer and the paper type set on the printer to the paper
type settings in the printer driver.
“Paper Size and Type Settings” on page 38
❏ Use a higher quality setting on the control panel or the printer driver.
❏ Reinstall the ink supply units already installed in the printer.
Reinstalling the ink supply units may clear clogging in the print head nozzles and allow the ink to ow
smoothly.
However, because ink is consumed when the ink supply unit is reinstalled, a message asking you to replace the
ink supply unit may be displayed depending on the amount of ink remaining.
❏ Use the Print Quality Adjustment feature.
