Bizhub 350 - Multiple issues

[GinaTallmanCPA]

Okay! Got the assembly out, cleaned the foam off of the little arm thing. Took some pictures in case someone someday has the same issue. Now, I'm going to put it back together. I broke one of these connectors (tore the wires out of one side) while I was disassembling it. Does anyone know where I can order a new one? Or can I just stick the wires back in?

Thanks!

Those connectors use a union, with a similar connector on each side. All these items are relatively universally interchangeable. If you separate the remain good connector from the union and take some good photos of the pieces, I will send you a new union and pigtail to attach to your solenoid. Can you do some basic soldering, to attach the pigtail? Send a private message if you're interested. =^..^=

Oh my god I would appreciate that so much! The connection that I broke is not the connection to the solenoid; it is the connection from second to last piece I took out to the toner replenishing drive unit that I removed in step 11 of the instructions from the service manual (see attached). I am not 100% sure I am following what pictures you want, but I was able to remove the light blue piece (where the wires tore out of) from the dark blue piece (which is still in good shape and has the other connection still in it) and here are photos of both of those pieces. The light blue piece is torn up from removing it from the dark blue piece with a thumb tack. I can probably figure out how to solder something (I have a soldering iron at home) but how do you do it with something so tiny? What is a pigtail?

A pigtail is just a short length of wire with the connector already pressed on. My suggestion is to make a few practice splices on extra wire, so you feel good about it before doing the final ones.

It sounds like your haven't done this before, so I'll include maybe too much detail. Please don't take offense:
You'll want some shrink wrap 2.5 to 3mm. It's a plastic tube that shrinks to cover your splice when it's finished. You slip it over the wire in advance, do the splice, then warm it with a match to make it shrink. (I'll send you some.) You'll also want some silver solder. ~0.8mm is about right. And some soldering resin to clean the wire ends.

Cut a 1" section of shrink, and slip it over the wire. Slide it at least 3" down the wires where you are soldering, or the soldering will cause it to shrink too early. Strip ~13mm of insulation off of the two wire ends, and twist then together end-to-end, not side-by-side. Apply a drop of resin (if it's liquid), or a tiny amount of paste type (the head of a pin, it takes only a little). Arrange the wires horizontally so that the shrink wrap is below and away from the soldering iron.

Warm up your iron, until the the solder melts onto the tip. Warm the wire splice from below, feeding solder into the place where the iron is touching the wire. The rosin will bubble, smoke and burn off. You'll see the solder migrating around the wire strands. When solder has filled the joint and gets shiny let it cool. When it's cool, move your shrink wrap into place and shrink it.

Sorry, If that seems condescending. I've burned up a lot of components over the years. The quicker you can get the soldering done, the better. And if you've got something sensitive nearby, you can clip hemostats onto the wire to slow the movement of the heat up the wire.

So here's your kit: gray practice wire, solder, a dab of paste resin, two pigtails & union, & 140mm shrink wrap.

Private message me an address, and I'll mail you stuff. =^..^=

BC, no matter how much time passed you are one of the greatest techs I know! And I know many.

I have made plenty of mistakes along the way, many of them avoidable. Maybe I can help GinaTallmanPCA avoid a few of my mistakes, lol. =^..^=

I guess that I edited too many times. I am now SPAM, and unapproved, lol.

Okay! Thanks to blackcat4866 I have the broken connection fixed, and thanks to femaster the toner assembly (can't recall what it's called) cleaned of foam and reinstalled. I am just following the service manual in reverse order for reassembling, but I have this spring that came off when I was disassembling and I don't remember where it connects to, and I don't see it mentioned in the manual. I know one end connects to this cable coming from the back, and I suspect the other end connects to this metal tab towards the front of the machine, but I am not 100% sure and since there is still quite a bit of assembly to do I didn't want to go any further without being certain. See the red arrow in the photo (it's not a great photo, I couldn't quite get enough light on it, but lmk if a better one would be helpful and I'll keep trying) - is that where the other end of this spring hooks to? I don't see anywhere else it might, but I haven't really turned the machine around so I can get a good look in there, and it is was not easy to reattach it, so I don't want to put more effort in if it's the wrong spot. Thanks!

GinaTallmanCPA I tried to look at the pictures in the manual to help you out, but they were just the typical drawing style. I pulled apart one of the machines at the office here and snapped a picture of each end for you...

femaster Ohhhh I just need to reinstall the next piece and it has that little tab on it. Trying to do things out of order. Okay, great, onward!

Have been there and done that, no worries at all. All I can say is that you are doing an incredible job at resurrecting that old beast, especially for someone that isn't a copier technician. You should be on the home stretch now.

About the only lingering issue, if I remember correctly, is going to be dealing with that service code and the over toned developer that resulted from the stupid little sponge pad. We can deal with that once you get to that point, but I think I should be able to help you to recover that developer without having to replace it.

Thanks 😊 I am having another issue though. I am trying to undo step 8 in the service manual, but there’s this little bracket and I can’t figure out where it goes. In the image it looks like it should go just to the left of the toner hopper unit, but I am just not seeing how it’s supposed to fit there. I’m so close I can taste it but this is baffling me!

[blackcat4866]

Sorry, it has been too long since I've seen one of these. femaster will have to assist you on this. He also has a live machine to look at, which I don't.

I am still watching, and will speak up when I can. =^..^=

i think that goes on after? the plastic cover is installed by the pic here.
good luck!

I ordered new developer femaster before you said you'd help me retone it so I just went ahead and replaced it.

I did 50 copies, they're still a bit smudgy but they are getting cleaner.

Now that that's done I can quit my job and go start a new firm....

Happy friday everyone

when you install a new developer you must run the adjustments, you cant just pop in a DV or DV unit without calibrating or it will never be right and just ruin a new unit.
running copies without doing the adjustments will screw up the ATDC level and it will never print right.
