Ricoh aficio 2105 duplex jam

[Serviser]

Hi people. Have problem with jam in duplex entrance. Mashine is general clean, but if you try to copy two sided every paper stay at duplex (jam code 21 and 73). I clean all complete, replace clucth, even put my duplex in another mashine, its works like new!!! so, somthing else is in problem, but I cannot find what. Any ideas???

dear duplex do not drive,,,,,, check the duplex conector some spark here,

Check duplex conector on duplex, and on rear side of mashine. Duplex works on another mashine....

I have found that in those faster machines, you can actually get suplex jams because of slick rollers in the papaer tray that is being fed from. The timing difference soesn't show up till it hits the duplexer. Check your rollers and the torque limiter in the tray.

Jimbo, thats exelent discover, but, try from 1,2,3 and 4th tray - all same.

Fuser exit switch, probably! How many copies on meter?

[schooltech]

It doesn't sound as though the duplex is the problem. Check to see if the fuser exit sensor is working perfectly. I've had quite a few of those stick. It is a reed sensor of-sorts, and they can have problems.

Feed sensor 21- duplex transport sensor 2
S42 Duplex Transport Sensor 2 Detects the position of paper in the duplex
unit.

INPUT CHECK
class3 no3 bit switch 3
0 (LOW) 1 (HIGH)
3 Duplex Transport 2 Sensor Paper detected No paper
sensor #57 (middle sensor)



Feed sensor 73- inverter tray paper sensor (stay on)

Try setting the machine in copy face down exit and copy single sided. That will tell you if the problem is in the duplex feed/inverter area or the duplex output/copy interleaving area.
This is in user tools.

I think Fridge meant face up, because face down goes to the inverter

Nooo, I meant face down.
In this mode you only use the left side of the duplex.

If it works in this mode the problem will probably be in the duplex transport, or the interleaving of duplex sheets and sheets from the trays (relay clutches and feed clutches).

If it still jams the problem is in the inverter or the duplex feed/stack area - B,C,F

[iMind]

OK sorry, but if he tries it with face up with no jams, that would eliminate feed stations, although I think theres no problem with them.

How many copies has the machine done?
Could be that the motor is under stress due to worn units.

I'm not sure if you have seen this from the troubleshooting RTB00 but it may go towards helping track the problem down.

Codes numbered 1 to 35
Indicate the paper did not get to a specific sensor within the allotted time.

Jam codes between 53 and 73
Indicate the paper got to the specific sensor on time but did not leave the sensor within the allotted time.

Jam code 21

Paper did not activate the Duplex Transport Sensor 2 in time.

• The page activated the first duplex transport sensor correctly but
did not activate the second transport sensor within the allotted
time.
• Verify correct operation of the second transport sensor using
SP5803-3, bit 3.
• If the sensor is working correctly, check the paper path for
obstructions.
• Turn on the fusing/duplex motor using SP5804-44 and then
check the operation of the duplex transport clutch using SP5804-
49.
• Check the drive belt and the associated rollers.

Thanks all for help!
When masine works one-sided, no mater face up or down, evrything is ok, there is no jams.
When turn duplex on, every copy enter in duplex, then go outside and stop. Jam code 21 is because they dont reach duplex transport sensor 2
Jam code 73 is because they dont leave duplex invertor sensor.
I have this two codes mixed. I put complete duplex unit in another mashine, and I dont have this problem, so duplex is ok, right?

Here is picture where paper stay

Now that sounds more like a connector problem.
