Normally, the Machine Identification Code "can barely be seen with the naked eye". However, what is being experienced is clearly visible. So, the issue may be related to the Machine Identification Code. If so, something is definitely wrong such that it would print a clearly observable bar on the page.
I searched our knowledge base and found this article for spots when printing for you to take a look at. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-821-2797.
When I print a small yellow dash will print sporadically on the paper. The location varies on the length of the paper but is consistently printing on the width. Only yellow is printing; no other colors.
I have attached a photo with the yellow dashes circled in red.
While this is not highly noticable, I would prefer not having these yellow dashes.
