Ricoh 3260c

[mailderrick]

I have been servicing this machine for them since the beginning of the year and so far has gone well..until monday. In the beg. of the year(Jan.) we rebuilt the fuser unit and 2 drums. then a month or so later did the other 2 drums and had minor calls from time to time on basic jams ,and things of tht nature.
Currently no paper goes through this machine.
This machine jams mostly 2 different ways. It doesn't matter if it is copy or a print or what tray it is from . If you send a single page job it gets stuck in the "switchback assembly"(if that is the correct name of the guide assembly to the left of the fuser unit) but does not make it out of that assembly
If you run a multiple page job it goes through the "switchback assembly" and down into the duplex assembly and the leading edge stops right under the duplex rollers. These 2 jams are very consistent and no pages come through the unit at all. No one claims to have done anything to warrant this and i am kind of stumped. My friend(I took along second trip for adice and is Ricoh trained) suggested a possible bad clutch on the switchback assembly as well as a spring that may be stretched out attributing to this. I am wondering why the 2 different types of jams though and why sometimes it goes all the way through that assembly, unless just by coincidence the clutch is slipping more on single page jobs. Any thoughts? i am lost. Fuser seems to check out fine and they were using the machine very heavily for the last 9 months. Total color page count was around 150,00 B&W approx 380,000

very common problem. Slide the fuser unit out and take the black plastic cover off the top of the exit rollers(2 screws). You will probably find the shaft that drives the rollers is popped up and out of place on one side or the other. Push it back down past the tab and problem should be solved.

Also there is a one-way ply in the exit section they may be slipping. It is item 19 in section 52 of the PL. B132-7028

thank you for the advice. I will pull the fuser out and look for the cover and check out the shaft. Also we manually tested the clutch yesterday and it does slip at times. The sping that sits by that one way bearing also doesn't look right and rollers in the exit assembly are bad. Is there aprt number fo rthe whole exit assembly so i can knock out a few birds with one stone. Thank you for the link to the manual. I have a few manuals on this machine already but if i have trouble or need a manual i will go there.

ok , we are meeting there today to take a stab at it as we could not get there yesterday. One more question i wanted to ask. The unit (that the one way bearing sits on) moves on the back side(of the machine) up and down and the front part of that unit is more stable and solid. I assume that is normal but trying to figure out if it is supposed to sit like that or if there is something missing. I may be able to go to a liquidation place to take a peek and see if it is the same but if someone here has a lot of experience with this machine it may save me time. We also noticed that where the guides are that send the paper to the duplex unit .. on the under side towards the front of the machine there is a notch on the metal like a spring should be there; however looking around i do not see a place that a spring would connect to that would make sense. Just a few thoughts and we will follow through on all the input so far and when it is resolved i will follow up so that everyone knows what this odd problem was. Thank you.

The sloppiness is normal, once it's inserted into the machine the pins in the rear lock into the frame to keep everything aligned. Yes, there should be a spring on the hinged silver metal guide plate on the bottom. I've always just replaced the whole assy once I start having issues with that exit unit (usually start getting nicks/burrs in the black plastic guides and catches the paper). Saves a lot a grief and time. Part # B1324430

Check for paper in the connectors on the rear frame of the machine too, this can cause all manner of silly jams and errors.

There is a lot off bulletin at that unit (exit unit) so change the hole unit, that will save you time in the future !

After waiting for a part to arrive from Ricoh that never made it , finally a guy sent me a working one from his almost new machine. I installed it only to find it jamming under the black paper guide flap in the paper exit assembly with the next page at the registration rollers. It is now very consistent. Every page everytime gets past the fuser and then right under the black flap of the paper exit(maybe an inch) and jams...any ideas? I'm stumped

[Llama God]

So are there witness marks on the paper or does it just time out? What jam sensor does it show at?

[mailderrick]

in the log from i think number 8? trans snr 1 all the way to (hmm i forget now) but 22? it shows paper late....i also tried to clear those by clearning the jam log..turning off the machine and back on but they were still there..then next time i went in..i had a newer tech with me that accidentally cleared system memory and now i have to figure out how to get the password back in(they had the copy screen password protected and now it shows to enter a code but no codes seem to work). Also before that happened another tech was having me check smc reports and clear..except when i executed..they all said failed. I am not super familiar with all of the tech rep in this machine and was going by this guys help who has been a ricoh tech for 25 years..however he can be difficult to get ahold of and even with his help and suggestions from other techs and another ricoh tech i took with me previously...this machine is still down. Are there any sensors known to go bad that would cause this?or mechanical parts? and even though the guy that sent me the exit assembly claimed it was working and new...the spring that attaches to the solenoid plunger was missing..i am sure it is necessary..i temp blocked the black flag in the up position just to try to get 1 single side page through.

I've had issues with the sensors on the fuser beside the cleaning roller. Try running the machine until it jams, check the latest jam code, swap those sensors around (there are two the same, next to each other) and see whether the fault either disappears altogether or changes to a different sensor.

The sensors I mean are on page 114 of the service manual, item 3, part number AW010118.

[mailderrick]

ok.. i will do that. also do you know how i can reprogram the user pin code that they had in..right now it still asks for the code which was 7000# and now nothing i try seems to work.

User tools - system settings - administrator tools - address book. It's in there.
