Figure 5-4. Printouts Missing Dots

Horizontal rows of dots missing on printouts may be the result of a connection problem between the print cartridge cradle contacts and the print cartridge contacts. This is known as an “interconnect problem.” You may be able to solve this problem using the following procedure:

1.Remove and reinstall the print cartridge. Make sure the print cartridge snaps into place in the print cartridge cradle. Retest by printing the printer self-test.

–If all of the rows of dots are printing, no further troubleshooting is necessary.

–If rows of dots are still missing in the self-test printout, continue on to the next step.

2.Remove the print cartridge from the printer and clean the print cartridge and print cartridge cradle contacts. Use a cotton swab lightly moistened with water. Do not wipe the ink nozzles on the print cartridge.
