go to step 3. with cleaning cartridge contacts and the ISS..

Just to clarify, you are talking about the ink cartridges or the printheads? I ask because the cartridges are single colors and the printheads handle two colors each. As indicated by other poster, the contacts in the carriage might be dirty, it is easy for ink to contaminate the contacts. If they cannot be cleaned with a dry cotton swab, then you will need to power off the unit and use  a cotton swab dampened with water to clean any excess ink. If the problem persists it might be an issue with the printhead PCA or the contacts may be damaged and require replacement.
