iRAdv C5235i - Random yellow line

**Arhts** · 02-18-2017

Hello guys,

First of all, sorry if my english is not perfect, but I'm trying my best !
So, i recently moved in the Technical Departement of my firm (about 2 weeks) and 2 days ago, an iRAC5235i came back from a customer with a weird issue.
Sometimes, totally random yellow line got printed when we do copy
I can't manage to reproduce this, it's really random. But until now, it appear only when I do copy, never appeared when i print directly something

Take a look to the pdf file

If anyone already encounter this issue or know how to repair this... Lemme know !

Thank you everyone

What are the service counters at? I would check your ITB cleaning assembly and your yellow drum.

Open up the printer and have a look at the drawer where the drums sit, could be just toner wandering around there, it sometimes heaps up on the drawer at the drums.
clean it carefully, beware you don't damage the drumrols... I prefer to use a tonervac.

try and swap the yellow drum unit with another colour and see if the moves, maybe that would eliminate the ITB?

I would Run a bunch if B&W internal prints to see if you get the yellow streaks. For example, print atleast 10-20 Counter pages which only use the black drum/DV. If you don't get any yellow lines, then try 10-20 Color sheets. If the yellow line shows up, I would look at the Yellow Drum/DV unit.

On the other hand, if while doing the internal B&W print you get the yellow streak, then you're definately looking at a ITB issue. Why? The ITB only contacts the black drum while making MONO impressions. It doesn't make contact with the color drums. When you make a color copy/print then all 4 drums are in contact with the ITB.

Hello,

Thank you everyone for your answers. I was off this week and just came back to work
I'm gonna run a few test this afternoon, but I know for sure that problem doesn't come from the yellow drum

I'll keep you update soon !
Thank again

Hi

It may be worth having a look at the yellow laser and its wires, this symptom and solution is a bit like your problem.

Product : image RUNNER ADVANCE C5030 / C5035 / C5045 / C5051
Title :
Banding is Occurring, When Printing in Color

Problem :
Banding only occurs around the color printed area only. Copies and PG test prints look good. Also, Black
and White prints look good.

Replacing both Main Controllers, HDD, Riser PCB, and Memory Dimms do not resolve the banding issue.

Solution :
In this case, there was a pinched wire on the yellow laser. Replacing the laser resolved the issue. Below are
samples of the banding that was occurring.
Note: in this sample there was yellow banding, but this could occur in any color.
