PRINT HEAD

6Troubleshooting

A dark and heavy coat of ink appears that starts at either side of the page and runs toward the middle. Clean the printhead and use a different type of paper. Refer to “Print quality problems” on page 6-13 for details on how the CLEAN

button works.

In vertical rows of dots, one row is offset from the others or missing. Make a test print (press the TEST PRINT button). If a row is offset, the ink from one of the ink jets is being deflected (A); if a row is missing, one of the ink jets is not functioning (B). Use the CLEAN PRINT HEAD button to clean the printhead; then make several test prints to help clean the paper path.
