ARM257 puking developer

[Akitu]

Hey guys!

I have an ARM257 that's dumping developer. I've already observed the problem to be the seal on the DV unit folding in as they're prone to do on this series; I originally attempted removing the seal and it was fine for 24 hours. I replaced the entire unit afterwards and it was fine for 24 hours. Machine has had the complete maintenance package performed, drum, charge assembly, cleaning assembly, transfer assembly and now 3 packs of developer between all the dumping.

Has anyone seen this problem persist through a complete consumable swap? Of course the problem machine just happens to be 4 hours away, so testing is not readily possible.

Re: ARM257 puking developer

The Gazelle's (AR-M208, an early predecessor) were prone to dumping developer. After a while we learned to replace the drum and blade with the developer change, and it lasted longer. I seem to recall that there was some change to the right door also.

It's a good idea to try to retrieve some of that developer from the paper feed units, otherwise you'll have no end of feed problems.

Does it do a good 25-2 developer stir (between 85 and 110)? How is the fill at completion of the developer change? What is the Gamma setting? I think I would take a close look at the 46-xx image quality settings, and perhaps try returning to the defaults. =^..^=

i never face this problem since i clean the td sensor every time during pm cycle.

Might want to look at the mylar that is just under the drum unit, attached to the body of the machine. Have seen these damaged that will cause your problem. Also if the tray 1 rollers cover plate is not properly screwed down have also seen this cause that same issue.

Good luck.

Consumable swaps are always done symmetrically (drum, blade, charge, dev) at same time unless otherwise specified (MXM365 is a fine example, 600k dev life 300k drum). Feed problems were addressed on site (almost 2 full DV units worth of DV dumped out, lots of clean up).

I'm wondering if your idea on the 46 sims might be my problem, I completely clean out the dev units (including TD sensor) yet it's always representing as 70-80 and coding EE-EL upon first initialization. Kicker is it appears totally fixed for upwards of 24 hours as I initially noted, which is making it more bizarre. I run 30 sky shots and it normalizes to right around 95-100.
I'm wondering if my HV PWB might be having some hiccups, tested voltage on site and everything is as it should be.

Mylar was intact Bil, I had seen that once before (the last time I had an issue with a 257/317 puking developer in itself)

Tray 1 rollers have not been changed yet, so the cavity was never opened.

Thanks for the tips gents, I'll be sure to check it out!

Given the issue described here, this may not help but I would suggest swapping out the main charger assembly. I would think that there would be other complaints if there were main charger problems but there have been problems with those charge assemblies. With the long travel time and the relatively low cost of a MC assembly, it might be worth a try.

I'll give it a shot, what could it hurt? Maybe I just got a defective unit from the factory.

Thanks!

I plead guilty to not reading your original post carefully. I fuss & fume when others do that, now look what happened. My Tuesday morning brain completely missed the sentence that said you had replaced the charge assembly. I even re-read your original post before responding. Can I blame it on being oldrn?

We'll chalk it up to a relapse of Monday-itis.

Re: ARM257 puking developer

Sharp posted a bulletin on the EE-EL code and it relates to the ATC sensor, they came out with a new one to resolve this issue, the PN is RDTCM0020QSZZ, however, I have not had developer dump because of this code. Also, check the transfer corona assembly, make sure it is free of developer on the contacts and is not damaged in any way.

I can't see any bulletins relating to EE-EL codes on this series on the Canadian Sharp Sales/Service Access Point (ssap). Are you able to link the bulletin here? Machine is circa '06 and I have not performed any specific upgrades to parts mentioned in bulletins. That part number also doesn't bring up anything in the parts guide.

Transfer unit on the right door was swapped out completely and I've since cleaned it out of dv the last 2 trips I was up there.

There may be a better way to post this but this may be the bulletin walterman was referring to

As long as it's viewable the format doesn't really matter. One of those ends justifies the means type of things.

Thanks for the bulletin. I'll check that out! That's a fairly recent fix for an older series, I'm impressed!

Akitu - If you want a free copy of the parts and service manual, shoot me an email and I'll send it along.

Paul@justmanuals.com

Very much appreciated Paul, however this is my dealership's primary line so I'm covered on that front.

On an unrelated note, I did email you from my work email in regards to an old thread about NVRam and Ricoh machines. Apparently someone had written a script to read the usernames and passwords from the NVRam? I'd be very much interested in that script/program as we have a refurbished MP161 that came locked down with non-default passwords.

If you need my email address to filter through your records just let me know and I can provide it.

The only thing more that i do (than whats been said) is conductive grease to drum frame shaft. I hate how these quirky calls always seem to be the longest to get to.
