having a double-dash image that repeats down the entire page.
Closest ID of the problem from the users guide is the "dots" problem.
Used the Tool Box and printed the Pitch Configuration Chart.
My double-dash image measures from "START" to just past a-2 (Xero) by 1/8" - meaning I have a repeating pattern of dashes 1 1/4" all down the page on my prints.
This started while still on the "starter toners" so I changed toner cartridge with the BLACK Dell toner and there is still no change.
So, after running the Pitch Configuration Chart the user guide says:
"Compare the space between the color spots on your output with that on the Pitch Configuration Chart, and then locate the cause of the problem."
So, WHERE do I locate the cause of the problem?
