Help please. Aficio 270

[TEKK09]

I've seen a similar problem on the 1045s. It was the diverter gate sticking on the cushion that it sits on at home position. The cushion gets gummy with time.

[Davide]

Yes, you’re right. The edge of paper is deformed. This happens also with the long way and any size of paper.
No, it is not possible any kind of regulation with idle rollers, the tension between rollers is ok, if I try to add some more the paper begins to bend.
AsTEKK09 says seems like “the diverter gate sticking on the cushion that it sits onat home position”
BUT I cleaned, eviscerated, checked theinverter dozens of times and I’m sure that everything runs freely (and strangely that there are no cushions at all, at least in this inverter)
I tried to test one by one via SP the inverter and duplex solenoids and everything seem to be ok with them, but I was thinking to replace all the sensors involved with new ones (just to be sure they are ok)


Please where I can find those sensors?
Kat*n and Precisi*n roll*r don’t seem tohave it.
I’ ve got the parts numbers of course and they should be:

Duplex Unit
AW01 0048 Photo sensor - GP2A28N1
AW02 0102 Photointerruptor

Interchange Unit
AW02 0086 Photointerruptor
B300 4506 DC Solenoid Gate Pawl Upper
B300 4511 Dc Solenoid Gate Pael Lower


Thanks for your time…

You have the optional interchange unit in the machine since you have a duplexer installed. Open the interchange cover and look at the guides. At the front and rear the plastic fulcrum pins have to be seated into the little holes. This is a real cheezy unit and they come out of place very easily, which causes jamming issues just like yours A look at the parts catalog of the interchange unit will probably help. (B300) product code. Another thing. The inverter harness is really short. Make sure the connector is fully seated and the harness is intact, although your problem appears to be entirely mechanical.

[Davide]

Thanks,I’ll bear in mind. Tomorrow I will check again paying attention to your recommendation .
In the meantime any other suggestion will be very appreciated.

I had the similar problem with a cl7000. Turned out to be a board problem. when i changed the sensor it still did'nt work.I ended up changing the inverter unit for another and it worked fine.

[Davide]

Nothing,still the same. Checked once again guides and plastics but without success.
Yes, the problems appears to be mechanical since the leading edge of paper (entering the inverter) is deformed.
So nothing remains to me, I have to renovate my search,

(Duplex Unit)
AW01 0048 Photo sensor - GP2A28N1
AW02 0102 Photointerruptor

(Interchange Unit)
AW02 0086 Photointerruptor
B300 4506 DC Solenoid Gate Pawl Upper
B300 4511 Dc Solenoid Gate Pael Lower

OR

Duplex unit(A896) and Interchange Unit (B300)

Kind of an old machine to be putting that amount of dough re me into, don't you think?

You mentioned the cushions were non-existent in your diverter....is it possible it's something as simple as a solenoid adjustment?
Do you have a WORKING model with a similar assembly? If so, I'd compare action of the good one vs. the screwy one, maybe it will become obvious what's wrong with the bad one? Could the plastic entry of the diverter be warped? As prev. tech. stated, the assembly is a cheap POS.
Also, can you try pushing the diverter gate down a fraction of an inch, AS IF it has its cushions in place? Maybe it's sitting a tiny bit too high....wouldn't take much deviation to cause a lead edge crash every time the paper is the slightest bit curled.

[Davide]

For what I can see solenoids adjustments are not possible (at least in this series, aficio 270).
They basically turn into on and off position, that’s all.
I thought it was possible for me to compare\use as donor machine an aficio 220 but unfortunately is in bad conditions and the duplexer is missing.
Yes, the plastic entry of duplexer could be somewhat “ bent ” (though I’ve done my best to remediate) but the point is that paper still can enter with no problem for some centimeters and halts only subsequently.
I think that although SP has confirmed solenoids and sensor are ok something in the inverter is a “ false positive”
I have no other ideas. All plastics are ok and can move freely.
One more thing.

Today I’ve noticed a couple of times that paper tends to enter the inverter gate UNDERNEATH the black plastic guide.
Does it have to be considered regular?

I’ll make asap a photo to be more clear.

thanks for you attention and patience

Yes I do.
And often (if not regularly) a brand new one is (and at the end, must be) an option (together with some liters of gasoline, at least in this case)
I don’t like particularly enigma or waste my & my neighbor time tryng to resolve desperate problems.
But forsome reasons that I will not explain in this circumstances, this time happens that I have to do my best to get a solution, otherwise I wouldn’t ever considered to open a thread, ask for help, steal some of the valuable time of forum members.
I have too much respectfor my neighbor.
