LPI has had a number of cases where a broken tab (or tabs) on the secondary transfer assembly which results in faded or washed out print on either right or left side of the page, or across the entire page in the case of both tabs broken. (Pic shown with both tabs correct/not broken)
There are two locking mechanisms in the printer that secure these two tabs and pull the secondary transfer assembly tight against the transfer belt as the right door is closed.
Example of “color band test” shown faded down right side from a printer that had the front tab broken:
