1515 leaves dev on copy

[Blazer1087]

Hi everyone....I have a 1515 that the cust has put about 15,000 copys on the PCU before they complained about gritty copies. I replaced the PCU yesterday and they called back today with the same problem. Its leaving develeper on front and back of the copy. They are using OEM supplies. Could this be a transfer roll problem? Thanks for your help

Sorry about the question:
Did you vacuum the equipment? The gap below the PCU?
You can see that when you close the tray and than open it again there is dust(developer dust).
I tell you this because i have seen that very often.

I did vacuum out the dev residue in the PCU area and it came back, especialy on the ledge above the transfer roll.

Just see the transfer roller...

I'd agree. Make sure the PCU counter has reset correctly too, it might not have noticed it had a new PCU fitted.

The last time I had seen something like this, the quenching lamps were out. That will cause an excess buildup of charge on the drum surface and start pulling developer.

[ricoco]

Yes. TonerMunkeh is right. You can also see that.
If that happened it could be increase more toner that it need.

I have also seen incorrect transfer current or transfer cleaning cause this.

[Blazer1087]

the transfer is set at the default setting, tried lowering it but no differance. Not sure if PCU counter had reset correctly, I'll check. I never thought about the quenching lamp being a problem...wouldnt a SC come up if it wasent working?

[teebee1234]

No SC code would be generated since it's not monitored. The output check for the quenching lamp is SP5804-003. If the output check is ok, try to observe them with the front door open, bypass the interlock and power on. I think there is enough gap to observe if they come on during initialization.

[Blazer1087]

I will check this today , thank you.

[Blazer1087]

Forgot to let you know that it was the quenching lamp, one of the led's broke off somehow so none of the lamps would work. thanks for the help

BOOM, Headshot! Every once in a while this blind squirrel finds a nut.

Now can you help me with my MPC3000 problem?

I just posted a suggestion to it.
