Whether from scanner, or print from my windows, or MAC, printer is skipping every other print line. I have performed all cleanings.

Click here to view an enlarged view of the timing strip.
The timing strip is a clear, plastic strip approximately 1/4 inch in height positioned horizontally across the center of the unit, just in front of the carriage drive belt. The timing strip contains many thin black vertical lines that help determine the carriage position during operation.
During certain uncommon tasks such as the removal of a paper jam, it is possible to inadvertently touch a lubricated area on the printer's chassis causing a small amount of grease to be deposited onto the timing strip.
Grease on the timing strip may result in poor print quality including; mis-aligned or distorted characters, vertical lines or, in some cases, an inoperable error condition (such as 5100) or knocking / grinding noise.
In most cases, it is easy to remove the grease from the timing strip using common household items. If you wish, you may follow the steps below to remove the grease from the timing strip.
Items needed:
-Clean, unused cotton swab
-Small amount of Isopropyl Alcohol or window cleaner
-Flashlight or other light source

It looked like there was a smudge on he timing strip I cleaned that off and the printer still skips every other line. This was not a gradual issue, one day printer worked fine, the next it started skipping lines.
