C351 and IU's

Thanks. But by colour shift, do you mean that on printouts the colours are not correctly lined up? Because that is what is happening... at least, i think the black is not lined up perfectly with the other 3 colours on printouts. Its like there's a "ghosting" or "blur" but its quite minor.

[laserman06]

That is correct. It is basically color registration. The machine layers the colors on top of each other to produce the finished print. If the registration is off then you do get the blurred print.

Pull all of your image units out.
Clean your LPHs.
Reinstall the IU.
See if it goes through the adjustments and comes to ready, without the P-22

Look in utility and see what kind of life the transfer belt has on it, it may be time to clean or replace it if the above doesn't fix it....... By the way how many total copies does this machine have on it?

Thanks for the info guys. Its monday finally, and i just got in to work so i'll give that a try. (Taking out the IU's and cleaning the LPH's).

The transfer belt should be okay, its not even at half life.

The machine has only done some 60,000 copies. I can give you an exact number in a few, its been a week or more since I remember last looking at the number but thats about the figure I remember it being.

Okay, from the webinterface:

Total
CounterCopy + Print
74055

Okay, I did what you said... the machine sat on 'stabilizing image' for a while, and then went back to P-22 once it finished.

I still think its only the black that's not lining up correctly.

If I understand correctly this began when you replaced the black IU, you have since replaced other IU's but the life has not been reset because the machine never completed stabilization. Try puting the old black IU into the machine wait for stabilization to complete and then check to see if the other color IU's that have been replaced life counters are cleared. If so you just happened to get a bad Black IU. Have it replaced and your set.

Leela, did you solve the P22 problem?

[Leela]

No, unfortunately I haven't. It looks like it may be due to a bad black UI, and I don't have the old one to put back in so there's not much I can really do at the moment

The reason it's not resetting is because of the P-22 code.
The first thing I would check is your black print head which is can be seen right when you pull out the K IU you can see a pin sticking to the right and just make sure it's not loose. If it is you can some epoxy to tighten it up. I've ran to this issue a few times and it's always been that.
To check your IU you can to the tech rep mode and "TEST MODE" and do the "Gradiation" and juts make sure the black looks fine.

OMG, that fixed it.

The little pin thing on K was not only loose, it came right out when I touched it... its totally broken off...

Still, I fiddled with it and got it standing in there (at the right angle by looking at the other IU's) and put the black IU back in... and it works.

P-22 has FINALLY gone away.

The IU Life counters have reset to 0 on all IU's.

And the black prints perfectly aligned with the other colours!

Hooray!!!

ty so much <3

[Tech02]

Glad to hear it. It can be a little tricky but once you figure it out it's pretty easy to fix.
