Posted: Sun Mar 13, 2016 7:28 pm Post subject: White Voids on Plotwave 500? |
|
|
Hello everyone, I have a chargeable customer thats experiencing these random white voids on a Plotwave 500, I'm still learning OCE's, if this was a KIP I'd totally be turning my attention to the transfer/sep unit.
I have already changed out all the corona wires, trans/sep and charge, also swapped the main charge unit with another just to test, no difference.(don't have that ability for the trans/sep unit). I have checked the dev bias and the pin on the drum, also checked out the encoder, all good.
OCE support as mentioned maybe it's the hard drive (I don't think this is a digital issue, by the looks of the pages they look analog), but thats nearly $2500, One of my fellow tech's have suggested it maybe be the developer toner running out? This machine has roughly 250k sq ft on it, never had a dev toner replaced yet.
This is a intermittent issue, it comes and goes. Sometimes we can print 100 pages and it only happens once, other times it happens not at all out of 20-40 pages.
I have attached a photo of the problem. Also the voids don't stay in the same place, random as well....any help would be really appreciated.

Have you tried swapping out the encoder? |

I have not, I did turn off the encoder via service mode, there is a service test I found to do that. (no change)
But I definitely could if the 360 encoder was the same part number as the 500 encoder, I'll look that up right now. _________________ KIP 3000/3100,5000,6000,8000,7700, 7770, 7100/7170, Color 800

Excuse me, i made a mistake. I have a 360 PW in my demo room.
Just checked and yes the encoders are the same part number, going to remove off my demo unit and bring out to customer to swap. Will update after, thanks. _________________ KIP 3000/3100,5000,6000,8000,7700, 7770, 7100/7170, Color 800

Swapped Encoder, no change.
I'm thinking maybe High Voltage Board? But unfortunately I can't swap out my demo 360 board with the customers board. Different part numbers for the pw360-pw500. _________________ KIP 3000/3100,5000,6000,8000,7700, 7770, 7100/7170, Color 800

I've had the same exact problem with PW500, 340, and TDS 750.
It's the Drum! I'm assuming it hasn't been changed yet. Make sure you put a little conductive grease on the ground when changing, If that doesn't do it then it's definitely Developer. But you almost never have to change it. Oce will say otherwise but I've never changed it in the Year I've worked on them and we have about 20 in the field. |

Is the coating wore off the end of the drum or the drum ground not making good contact? If the developer is going bad the customer will notice the waste bottle filling up inbetween waste bottle changes. _________________ "If you mess with a thing long enough, It'll break" |

Wanted to post a UPDATE;
It was the developer:
I was in OCE training last week for the Colorwaves and started chatting with the trainer about this issue.
What was happening was, the developer was losing it's charge in the developer unit, and falling down and onto the transfer/sep wires/unit. Causing a short and thus the random/intermittent white voids.
I am new to OCE's and Plotwaves, but knew from my KIP experience it seemed like a transfer/sep issue. I was not aware or didn't really think about, how long developer lasts inside a Plotwave (this customers plotwave had about 220k sq ft and had the original developer) obviously KIP doesn't use developer and uses toner inside it's developers.
It was a good learning experience. And the customer is happy they stuck with me and waited so we didn't start throwing parts in the machine. Some of the OCE tech support guys were recommending HD's ($2500) and High Voltage Board ($1500, which was my next guess too). Since this was a chargeable customer. _________________ KIP 3000/3100,5000,6000,8000,7700, 7770, 7100/7170, Color 800
