KM-5050 J61 When Duplexing

[k0rpl]

Have a KM-5050 that is giving constant J61's. Already replaced the entire switchback section, and the Duplex Clutch. Page will come out the Center of machine about 3-5 Inches and stop. Remove Jam, restart, and the machine will do the same thing. All switches/Sensors appear to be working in SIM 031/030.

Any help would be appreciated.

try replacing the exit assembly it may be the timing sensor or even the solenoid

[moussmouss]

I am having exact problem right now,only when feeding from LCF.FSW1 and all other paper sensors replaced,exit section replaced,will let you know if I come up with solution for this annoying J-61.

Is it looking for longer than 8 1/2 x 11 paper?

Same here... only gives J-61 when using LCF... will do single side all day. My only solution so far is a note on the copier *PLEASE USE TRAY 1 WHEN DUPLEXING*
The original post here is a year old, someone musta figured this problem out by now...I can't spend more hours in that customers office. Service manager getting suspicious, and that woman is NOT MY TYPE!

i use to have these kind of problems on the falcon II's but it was the one way bearing in the switchback section not allowing the paper to be feed back in for 2nd side printing.

Large Capacity

Yes, but again it ONLY jams when using the LARGE CAPACITY FEEDER when duplexing. Tray 1 and 2 work fine...
And yes I installed the thick mylar spacer update for the sensor, and firmware.
BTW, it will do up to 3 without a jam, but 4 or more will jam.

Had same problem , still had to replace switches , we replace both switches at the same time with mylar backing .

PF 750 Duplex jams j-61

KM 5050 with PF 750 only jams when duplexing. J-61 jam code. Trays 1 and 2 will duplex all day long. Only gets J-61 duplex jams when feeding from the PF 750 LCC unit.
Have done firmware update, and replaced:
On 5050:
Duplex unit
Exit unit
all 3 convey switches (with mylar backing)
"stretched" the springs in duplex and side door.
In PF 750 replaced:
drive motor
all paper feed tires
one way bearing
one way shaft
all clutches
checked connectors thru entire system
the tray hook is not cracked

Any and all help greatly appreciated.
The system can run 1 to 4 duplex ok, but usually jams after the 5th.
sometimes will run up to 20 before jamming.

Don't know if it will help at all but I know that the 30/40/5050's LCT are notorious for the paper feed tray having clips that break and cause a variety of issues, such as skewed paper through the paper path.
Just a thought...

[k0rpl]

I forgot to post this.

I was able to fix my J-61 Duplex jam problem when feeding from a LCC Only.

What I did, was to take the springs that put pressure on the Nylon rollers that contact the gray rubber rollers on the Duplex section. I stretched the springs about 2mm, and that took care of the problem. Been running fine for about six months.

Sorry about the delay.

Re: KM-5050 J61 When Duplexing

replace both clutches in the vertical feed unit part# 302gr44120. both clutches are the same.
this will fix j-60,61,and62s when duplexing from the pf-750.
apparently these clutche get week and slip slightly throwing off the paper timing.
i have fixed at least five machines with this problem.

I, too, have had to replace these clutches. Actually there ate three of them, all identical. =^..^=

Re: KM-5050 J61 When Duplexing

Really i do not know why wasting time for repair just change the wiring connection for Duplex to solve your problem.

part number: 2GR46421
