Vertical streaks in Cyan

[sarahgracie]

 Hi there, 

My Xerox Phaser 7800 is printing white streaks in Cyan only. I have cleaned all the printhead lenses and replaced the Cyan imaging unit with no help. I'm at a loss for what to do next. 

Thanks,

Sarah

If you assuming a very well cleaning of the printhead lenses, it remains a problem from yhe Developer Housing  (who can have some debris on developer material) and it means you need a tech to replace Developer material or even Developer Housing plus Developer material.

I suggest you to use a single color feature for each color through the copy mode then you will pretty sure if it happening only on cyan or not
if yes so Sounds is a developer housing issue as gabiene said or it could be too a faulty led prinhead “it happened “ .
