70/71 series Developer problems

[ihatefinishers13]

Alright folks, I've about had it with developer pull issues. The 50/70 and 51/71 series has been wreaking havoc on our tech's.

Mostly black, but occasionally color DV keeps getting pulled. It used to be that the process units were the culprit due to the mylar under the blade... then it was the MC PWB that would fix it... now it's the DV units that sometimes fix it, but also ends up being the process unit AGAIN.

We replace the DV because of Zebra Striping (DV is pulled), so we wait until it comes back as we've had it be a fluke sometimes. Most other times though, we have to replace the DV unit AND the process unit because if we do one, the other ends up also being the problem not long after.

Anyone else have DV pull issues everywhere?

The only other time in my 8.5 years that we had this kind of issue, it was the waste boxes causing it on the 4141 series.

My guy... I've been fighting those Phoenix DV pulls for years. *CRIES*

I just replaced a process unit YESTERDAY for one of my clients MX6070.

Although I haven't experienced these issues with the Phoenix2 boxes. :\

If someone knows the answer, I would love to have it.

We have, knock on wood, only had this happen to us a couple of times and it was because of the charge grid shorting out, not one of our MK kits have made it anywhere close to PM all have the classic Sharp crappy charge grids. We had it happen on an MX5071, yellow developer pull due to charge grid shorting and the other was an MX-4070v, Bk developer pull due to charge grid shorting.

A dirty erase lamp LED will cause this everyday. But yes, it's known to happen no matter what.

Is the same happening on the new BP series of copiers?

No, nothing on the BP series yet... just the ADF front paper guide... cheaply made.

In case you don't know, It's mounted on the machine so changing the process unit doesn't matter.

BP Series have a charge roller and not the grid system like previous sharps, so I am optimistic about BP Range.

No coronas on the BP series, now charge rollers so I doubt it will happen. In saying that I have a BP70C65 which has done almost 1.2million in a year and I haven't had it happen....

Re: 70/71 series Developer problems

I had problems like the one described, but in all cases problems caused by toner. Bk toner boxes had hardened, rock like pieces inside that went down to DV units. In all cases I had to replace developer and completely clean DV unit and hopper units.
Never color, only Bk toner.

I used to carry a Mr. Coffee coffee strainer we had such of problem with this. LOL Take the DV material out and strain it. Vacuum the DV unit really well and you were good for awhile. But hasn't happened in years now.

Good luck

What company were you getting your toner from?

OEM Sharp toners. Used to drive us crazy! Seemed to mostly affect the black as mentioned before but I have seen the colors do it also.

Yeah, they were my favorite, they were the only ones taken. Which model did you use?

Re: 70/71 series Developer problems

have you seen the bulletin for the new dev units? the dev spillway hole is larger and makes the dev amount less likely or over fill / over tone. perhaps this is an issue? then charger arcs and it pulls all the dev.
CCE-2027R... crap only applies to 50 and 60 ppm copiers
