When printing there are grey streaks which are printing onto the paper.

Gray streaks are normally caused by the black toner.

Some streaks that initially appear grey are actually very light blue and are caused by the cyan toner.

Hello @lcstudio

 

Try the following 

 

Make sure printer its directly to wall outlet 

Print a supplies status page to ensure that all toners have sufficient material available (if one or more its out replace)

Ensure that its only when printing , try to do an scan and a copy to isolate 

Print a demo page from reports menu

Process 2 cleaning pages from the service menu on the printer(printer will request paper on tray 1)

Process 3 color calibration from the system setup>print quality>color calibration >calibrate now

print another demo page so you can compare the two pages

If you see an improvement repeat the process 

If same issue try the following 

Send a print job to unit from tray 1 as soon as you see the whole paper is inside the printer open right door remove the fuser and remote the transfer belt , review if you can notice the line on the belt or not , at the same time remove all the toners each toner has a green drum review if you can notice the line on the toners 

Share your results
