HP Color Laserjet M452, repeating print defect 28mm

[Barry_TSE]

CAN YOU IDENTIFY WHAT MIGHT BE THE CAUSE OF A REPEATING 28MM PRINT DEFECT?

You sure it's 28 mm ?

Troubleshooting manual has repeating defects of 22,6  23,6  29,6  35 mm

It's odd. Rollers are usually consistent defects. In this case, I measured the defect as wandering between 27 and 29 mm.

What's 1 or 2 mm among friends?  What is the suggested component to look at?

My guess is the transfer roller.  I will give that a try
