Re: White Streaks When Printing Yellow

Thanks for the advise everyone.

Luca72 I have not tried to clean the doctor blade so I will follow your instructions and post the results.

Thanks

Luca72 you were RIGHT!

The doctor blade clog was causing the yellow streaks to appear on the prints. I follow your instructions put the PCU back into the machine ran solid yellow prints and they were perfect!
Thank you so much for sharing your expertise with me. I appreciate it a ton!

Have an awesome rest of the week.

Re: White Streaks When Printing Yellow

come on, it's the doctor blade clogged, with your fingers, turn the gear of the development group back and forth, about twenty times, also give a few taps along its entire length, under the development group with the screwdriver handle between one turn and the other 'other, if it does not disappear completely> replace, you may notice this even from the pm

I give you a suggestion to turn the developemer unit by hand, without breaking your fingers (especially in winter), you can recover one of these gears, from the drive unit of a scrapped machine, and keep it in the tool case...ciao
