AR-407 with f2-31

[axyun]

Customer called with quality problem + I told them that on last service call they would need the drum + blade + developer. I called them several days later and they said they ordered the items online. That bugged me but I agreed to do the service anyway. They called again when items were delivered and wanted me there as soon as possible. I got there third day after delivery and when I did they said the janitor( it's a daycare/school) had installed the drum and blade but they needed service because there was excess toner in machine and jam light on with no paper jammed.
I vacuumed machine and there was no paper jam but after blowing out transport sensor the jam message went away and now there was f2-31. They said they had also just replaced toner. I couldn't remember if this was a drum id sensor type code or the one you get when the sponge roller in the hopper needs replacement. I took out the toner and the sponge roller was intact. I took apart PCU and cleaned out recycler unit and cleaned both sensors and reinstalled drum + blade. Did sim 14 and f2-31 came back. I changed developer and did 25-02 sim and got abnormal dev ref EE-EU.
They said the seller told them drum was OEM and I assumed it was but didn't see the box around. I told them i would get back to them tomorrow after I did more research on f2-31. I am assuming machine was working but with poor quality before someone (janitor?) replaced drum + blad + toner and then machine went crazy. I know this is a long story but I wanted you to have all details.
I know there must have been other f2-31 posts on here but when I searched for F2 got no results and not sure if i am using the search feature on here properly. I did an error code search but there were 120 frames and that seemed too ridiculous to go thru. Any help is very much appreciated. If I had a toner and dv unit I would try swapping but I don't and my next move would be to swap drum as maybe some defect. Also they had drum unit out for a day or two with drum fully exposed which couldn't be helpful. Frank/ActionPhotocopy

Re: AR-407 with f2-31

Once you've cleaned the drum mark and ID sensor, you'll need to run 44-02 to reset the sensors. Until you do that, you won't get past the F2-31. Next you'll need to re-run 25-02. If it still comes up EE-EU (overtoning), you've probably got a worn toner feed roller that's dumping toner by the ton into your developer. I hate to tell you this, but you'll have to change the toner feed roller and seals, then change the developer again.

I suppose you could try to de-tone the developer with 50% fill prints, but not until the toner feed roller is changed. You're aiming for a 25-02 value of ~90 to 95.

Don't forget to bill extra for their stupidity. =^..^=

most of the time it is that sponge toner roller, you can change dev and the very first copy will jam and be overtoned because of excess toner.

I would not trust a customer like this or any of the work they had done or products they bought.

my bet is the sponge roller here, replace it first then do a dev change, if you want to go through the aggravation go into simulations and turn off all sensors in 08 (I think) and run about 50 sky shots of legal to get you back in range.

I would walk away from any customer that did this IMHO

Re: AR-407 with f2-31

I did remove the toner from the hopper to specifically check the sponge roller and it looked fine. I have seen them all chewed up. I did not do the 44-02 as i had forgotten about. I don't think this is a sponge roller problem as when I changed the developer it was not excess toner in the unit. Also the EE-EU is undertoner reference and EE-EL is the overtoner ref. I only know this cause I check the manual when I got back. I suspect this has to do with the drum sensitivity /id sensor and hopefully the sim 14. sim 44-02 and 25-02 will get machine on track
I thought the same thing as you both did that it was a worn sponge roller because they had just added toner though she did say that she couldn't put the whole bottle in as there must have been some in there and maybe she misread the toner message.
The cleaner unit was clogged with a bunch of caked up toner and plenty of toner buildup under the blade. The day started off great I had a good 6 mile run tis morning and felt great. my fist call was a $900 call on a Xerox WC Pro 428. Then things went downhill. My car bottomed on something and $500 of that $900 will go for a rack and pinion job. Then the f2-31. I 'll keep you posted on this. Frank

Re: AR-407 with f2-31

Usually if the sponge roller is bad, allowing too much toner through, the drum will constantly be covered with toner, along with most everything else near the drum unit. Congratulations on being able to dump the toner out of the toner hopper - it isn't fun, easy, or a clean job. The roller only has to be worn enough to allow toner to pass by it. On the other hand, your explanation so far has been pretty thorough so I assume the drum is not being coated with toner.

If the janitor used the vacuum to clean up their mess after trying to get that toner in, maybe the toner density sensor is blown. Did you check the drum sensors to make sure he didn't unplug one while he was replacing the drum & blade?

Is the toner bottle still there? Make sure it is for the AR407 and not the SF2030/2040 model - they both fit, and if the SF was installed will cause the same symptoms you described. It will also suck toner from the DV and fill up the WT bottle.

Re: AR-407 with f2-31

If I'm not mistaken 44-2 and 44-4 is for drum mark sensor and I.D sensor, try to access the simulation and run this program and then adjust VR1 and 2 to plus minus 200. Usually even OEM consumables can work with this machines, I've always encountered overtone with this machine the only thing I do is to increase the value of toner drop (Sim 80-2) in special mode.

Hope this can help...

Re: AR-407 with f2-31

Zootech is right you can get the wrong toner in that way, have seen it done, also TC 44-2 is auto adjusting when you run and execute it, it aint like on the old one, there is no pots on the drum unit to tweak.
Clean both ID and DM sensors with a shot of caned air, and run TC 44-2 and either it will callabrate or it wont, giving some kind of error code F2-## as I recall, non OEM drums, can cause the sensors to mis-read, have seen that once or twice.
One thing on them toner hoppers with that spong foam roller, I have seen them pop out of place just enough to dump, causing that error code, but not be worn out, make sure its installed properly, even made spacers to keep it in place better, flap off of a drum box, hole punch a hole, trim to make as shim washer, install on gear side of the roller, inside hopper next to bearing, puts a bit more presure on rear holder.
Hope this helps

Re: AR-407 with f2-31

Thank you all for the very useful info. I will go back next week and start from scratch. I was there again today and cleaned drum mark and sensors again and checked that the drum mark was in line with sensor though I did not check to se if a sensor was disconnected. I did a sim 14 + sm 44 02 and sim 25 02. Got EE-EU abnormal ref on dev sim again. I also was careless and busted transfer corona wire and my main tool bag was in car which was being repaired so could not rewire.
There was toner dropping onto transport platform and onto transfer corona possibly from bent soft mylar on drum unit which I tried to straighten out. Machine kept cycling and saying maintenance required without going into ready/ Must return next week with corona wire + drum and see if I can ge hold of toner hopper just in case I missed something though spong roller looked good.

Re: AR-407 with f2-31

keep it simple frank, Make sure they have right supplies and foam roller.

Re: AR-407 with f2-31

The toner is generic but I have seen this at other offices and at this one on previous clls and it has worked consistently. Frank

Arcking: I think you're thinking of the SF2030/2040. They're the predecessor, and very similar build (but no VRs).

The generic toner is a warning signal to me. I still haven't heard what your 25-02 or 25-01 readings are. If you're getting 65 or less you have a drive problem to the developing unit, or just really dead/undertoned developer. This may help:

Very light gritty copies. "Add Toner". "Replentishing Toner" indication. Adding toner does not help. Gear noise, on AR-335. Bearings inside mag roller sieze, spinning the magnets & dumping developer. Broken gear 28T in main drive assy. The developer is extremely overtoned, just not stirred. Clean up the toner/developer spill. Replace the main drive assembly (CFRM-0939FC53), developing unit (CBOX-0116FCE1), and developer (AR-336ND).

I've never seen the EE-EL come up on a Cougar, even in this situation. =^..^=
