Still have vertical lines going through all colors OKI C931

[JustaPrinter]

I've wasted a lot of money on trying to get this printer to print flawlessly

All rollers in the pathway have been changed

Drums are near full

plenty of toner

transfer belt replaced

lines show on paper & cardstock more visible on cardstock.

Only thing that hasn't been changed is the fuser unit

Was there a time when the printer did not print the vertical lines?

I recently purchased it from a print company who upgraded. So I cant really answer that. Do you think this is just the normal quality for this machine ?

Guessing I'm not the only one to check out our new member's profile to see if it was Dan?
Welcome @JustaPrinter BTW, I've a feeling your posts may get above average number of views because of your handle.

When you purchased it did they say it was running or had problems? and sorry but .... change the fuser unit?

I have no experience with OKI printers but the vertical lines seem like they should not be there. Since you've basically replaced everything else, I would try the fuser. If the lines persist, the only other thing I can think of is to try a different stock? I assume you have tried contacting OKI and that their answer is that what you are seeing is normal?

Take a look at the transfer belt to see if it is marked up, I would get that when toner would build up on the front of the transfer belt cleaner.

If you can open the front door while it is in the middle of printing you can check the image on the transfer belt, if that looks ok then look at the fuser, it might be done. Since it is doing it across all colors its happening at 1 point.

Just as a side note, I used the 931 for envelope printing, I did not do many solids on it.

Se as linhas verticais estiverem em todos os núcleos, você deve pegar um pedaço de papel e limpar levemente os LEDs da imagem que ficam na parte superior da tampa.

tente isso e depois dê seu feedback.

Coincidentally I was just going to say exactly that, you pipped me to the post!
