konica 222 feed problems

Re: konica 222 feed problems

And it has plastic casing (#Hansoon).

Errrr.... I said and meant "Cage" not case. The cage is where the little needles ("rollers") are sitting in holding them in place.

Apologies Hans, My bad. Misunderstood it.
Do you remember a case where plastic cage is used?

No problem Pal.

Not sure what you mean exactly but when you're not hinting at chickens in a transport cage, is this going the 50-Shades-of-Grey direction? LOL

Re: konica 222 feed problems

There is an electromagnetic clutch in the main feed drive assembly, behind the paper trays, that has a nasty habit of failing. This is where your problem likely stems from. You need to remove paper trays, bypass and both feed assemblies to get at it. Also remove the back cover to get at the connector. The drive assembly is held on by five screws.
The clutch part# is 9322 1500 12.
Hope this helps

replaced feed tires in both units and cleaned one ways. first tray works fine second tray still doesnt work. would you still think it could be that clutch since tray 1 works fine now

There are clutches on the 2nd tray feed unit. One turns the feed roller and one turns the vertical rollers. If the paper is not leaving the tray it may be the smaller clutch. If the paper is getting out of the tray and to the vertical roller it may be the bigger clutch. There is also a dual gear assembly with a one way bearing. Remove it and clean it up.

this copier has me wanting to find a new profession. after replacing all feed tires and one ways the 2nd tray worked fine but the fisrt tray will make a copy then jam in tray. i took out bypass and feed units and replaced clutch that sits behind bypass. no change in drawer 1 still jams and now drawer 2 makes a gear grinding noise and doesnt work at all now. took everything apart 5 times and dont see a reason for the grinding noise in tray 2. didnt touch the feed unit just replaced clutch and now it grinds. everything seams to turn freely bypass works fine. i know you cant see the machine to know whats causing the grinding noise but hope someone has had this happen before and might have a idea. does mot grind out of tray 1

Re: konica 222 feed problems

BH222feed.jpgCheck or change items 32 and 33 make sure 32 is not put on backwards. There were several mods for cracking trays which can cause miss-feeds. Check to see that no wires were nicked or pinched by the bypass mounts.
You did mention in the beginning that this was a used machine sale. If it were me I'd be looking to swap it out at this point.

I use a Small flat file to ruff up the shafts it they are worn out.

Re: konica 222 feed problems

Ah! An opportunity to step up on my soapbox!

You may have slipping one-way bearings in the feed units. Quite often, these one-way bearings are not treated correctly.

You'll want to soak out the one-way bearing (aka Torrington) in alcohol, and run a Q-tip around the opening. When it's dried a little add a single drop of light oil (like Triflow) to the bearing.

Check the shaft for wear. It's OK if it's smooth or shiney, but not OK if it has worn down in size/diameter. If the plating has peeled off you'll need to replace the shaft. It is common practice (and completely wrong) to score up the shaft with steel wool or green scrubbie. This action damages the shaft, forcing you to replace it. The one-way bearing needs the maximum surface contact with the shaft, and scoring up reduces the surface contact, and reduces the shaft size.

Some techs replace these one-way bearings every other tire change, or even every time. =^..^=

Hey Allan, just referring to what blackcat said about shaft . see his post above, this is from the same thread. Everyone has his own method for getting things done and that is perfectly fine as if it produces the desired results. But i have to agree with blackcat on this one. I guess if you clean it from dirt and grease and lube the one way it should be fine. if the shaft is worn, you will have to replace it. But rearly do i replace a shaft, only on very high volume machines and not because they have problem, but for maintenance purposes .

Yes i do clean out the clutches and even replace them and entire feed units if the shafts and bushings are worn out. I have fixed tones of feeding problems like this. If a shaft is shot its shot and needs to be replaced. Sometimes the shafts would get a high mirror polished surface and the clutch does not grip on there . By filing it a bit it gives a textured surface that would let it grip again you don't even remove 5 microns from it. You need to be care full to clean the shaft with contact cleaner before and after.

Re: konica 222 feed problems

this copier has me wanting to find a new profession. after replacing all feed tires and one ways.

Pulling hairs, it happens to all of us at some time or the other, this is your's.

You said you replaced the roller clean, then replace the roller in tray 1 and it worked but now jams again. see the parts list attached and check that every thing is in it its place correctyly, especially the springs and the actuators. make sure they are moving freely and spring back easily. pay attention to item number 9 which i believe is the feed actuator, it has a spring on it. check this actuator if it is not bent or piece broken from it. maginfy the drawing so you can see where all the parts are exactly.
There are four sensors on this pickup/feed section, make sure they are sitting firmly and not loose.
IT is picking up ok, therefore CL4 is ok,therefore you should replace CL2 which is the feed.
Check all the items that has one way bearings, turn them on the shaft with your hand and make sure they are not slipping. If it does not slip when you turn by hand then they are fine.

Also, where exactly does the paper stop when it jams, and does it happens every time it makes one print or copy.
ARE there any jam codes. look at the list and see the one that is the most recent and post.

tray 2. put back the old clutch that you replace and see what happens, is it the correct clutch. compare with the old clutch part numbers.

According to the parts list, there is only one clutch in the drive unit and i think you replaced it already.

If the problems are intermittent, you could have pinch wiring, or faulty engine pwb.

Lastly.. can you swap tray 1 with 2 or are they diffrent units. don't know the machine really, but looking at the drawings.

Lots of konica techs out there that knows these machines. what would you do.


neil greenhough i see from his posts, has lots of experience with these machine, his input would be nice here.
