================================================== ===
Brian8506 ???

are these codes in the Service Handbook ?? they are not in the Manual> just check

found this > Jam 010E--delay
from the right and left paper decks

The one-way clutch (FB2-7596-000) situated next to the upper feed roller is bad and causing drag on feed shaft & roller.

The "outboard" one-way clutch FB2-7597-000 (nearest the feeding clutch) and the feed shafts FB2-7598-000 themselves also wear and causes the jam codes. Replace the one-way clutches and the feed shaft to resolve the delay jams. ---CLEAN EXCESS OIL FROM CLUTCH OR REPLACE PART

NP 6050 / 6551 / 6560
E712 = is a communication issue from DF to Printer--RDF-D1
stationary jam or an intermittent type of jam. There will not be a jam code.
Check for shorted orange wire to RDF-D1 switch sw2.

Check to see if reversing roller motor M2 is operating normally.
If it appears erratic, replace M2 and the Driver PCB for M2.

Online Tips

NP-6050
DUPLEX JAMS
Canon 6050 Duplex Jams are sometimes caused by the LTR size paper cutting into the user side deflector on the fuser assembly (the white Duplex deflector which is right after the fuser on the fuser drawer ass'y). What happens is that the deflector is designed with European paper in mind and the American size paper is a bit smaller and causes it to cut into the front deflector and sometime this cut in the deflector causes the edge of the paper to catch and jam. To fix this I have been taken the deflector out and with a hack saw blade carefully cutting around the front and rear deflectors and twisting them off, therefore taking the two deflectors totally off. Canon has come out with a new deflector ( it is black in color ).

DOC FEEDER JAMS
If you find that the document feeder jams when using it to copy a 2-sided original check the pin on the rear side of the left paper feed flapper, it may of broken off. To fix this problem without having to worry about it happing again drill a hole through the flapper the same size of the pin and glue a hex wrench cut to the same length that the pin was. (Here is the key though, the hex wrench must be just slightly larger than the hole, this will prevent any chance of it coming loose.) I have had to do this to 6 NP6050's so far because the flapper has been hard to get. However it works so well I will not be replacing the flappers.

Canon 6050 RDF jams, this is caused by the fact that the machines are designed with European size paper in mind and that it is just a bit larger than US size paper. This causes the American size paper to cut into the front feed paper ribs on the right side cover of the RDF . The paper is actually cutting into the rib and causes jams or the originals to get a dogeared edge. The fix for this is to snip off the front rib or ribs on the right side cover and file them smooth.

Re: Canon NP6050 False Paper Jam

I finally got around to reviewing the information and I appreciate it. I've been a service technician for other mechanical equipment for 35 years, but not for copiers - so I'm not familiar with the terminology of copier parts. If you would patiently walk me through this I'd appreciate it. I can supply photos if need be.

The last two codes set, E713, refer to the sorter. I assume the sorter is the big auxiliary unit that attaches to the side of the copier. I junked it long ago as I had no need for it. But the copier did work fine without it until now. Since it no longer exists, it can't be that.

Here's some additional information that may be relevant: Paper drawer #2 does not function. I had to select drawer #1 manually rather than use the auto select feature or it would jam. However with drawer #1 selected, it always would work fine.

What should I look for first and where to look? Is the problem being reported located in the area indicated by the LCD readout, or is it elsewhere?

------------------------------------------------------------
error codes 713 could have been when sorter was attached//

you are dealing with a product that is over 15yrs old & and had over 300 technical tech pubs
u need an old trained Canon tech to view the situation //

all deck and cassette operations can not be fully explained here !!!/

observation>testing>inspection>removal>inspection> and on & on & on


010E codes = probably need the one -way clutches replaced
Cassette Side Guide VR bracket is probably bent

Re: Canon NP6050 False Paper Jam

I'm happy and proud to say that I solved the problem.

My first thought was that if the LCD report about the right side #2 door section was accurate it should be in that area and nowhere else. But there was nothing to be seen there at all. So I thought what if the door isn't closing properly? It seemed to stay closed OK. Since I know this machine is loaded with sensors, I next asked what it is that senses that the door is closed? I located the optical sensor but I had no way of verifying the operation of it - so I decided to compare it with that of door #3 beneath. I inserted a screwdriver to replicate the action of the door lever to activate the sensor. The sensor for door #3 would beep when I moved the screwdriver around. Then I tested the one for door #2: no beep.

I could see that the sensor itself would be a bitch to access. I decided not to remove it unless it was absolutely necessary, and in scrutinizing it I found the problem. It had come unplugged from the lower wiring connector. Plugging the sensor back in was also tough to do, but after I did it the error report stopped and it's back to normal.

As for the relatively small piece of torn paper that initially started the whole issue, I can only surmise that it must have been lodged in the machine for a long time and eventually got caught in that area. Maybe opening and closing the door jarred the sensor plug loose - impossible to tell.

Persistence pays.

I'll print this out and save it as a reference for the next time this over-engineered monstrosity malfunctions.

Re: Canon NP6050 False Paper Jam

i have the same problem of false paper jam. no paper but indicate jam at lower door. replaced vertical path sensors ps27, ps 36, ps 30 all good.

look for the recent jams the screen displays all 000 000 etc. on the screen. what could be the possible problem?

if i insert a piece of paper on sensor ps36 and ps30 the machine will beep, an indication that the sensors are working. But on Sensor PS27, no beep at all. i already swap the sensor with Ps30 still no beep on PS27. machine indicates Jam at lower right door at power on.

In my case I still have an occasional report that the door is not closed, but now I know with the problem is. It's a mechanical problem involving the closing of the door: if the tab on the door that activates the sensor is not aligned properly it won't activate the sensor. Giving the door a good slam corrects it.

As I mentioned, check the sensor by inserting a sufficiently large object into its path to see if it responds. In my case it wasn't a bad sensor. It can also be either the wiring connection or the hardware piece that activates it.

Re: Canon NP6050 False Paper Jam

i tried your suggestion but the same " open right door remove jam paper" the machine is pointing a jam at the middle right door.

jam at power on. i tried the reset *4* same problem

Here is the jam code

B_JAM0: 0208 010A 010A
B_JAM3: 010A 010A 010C
B_JAM6: 010C 010D 010C

==============================================
17 sensors
u never look at the obvious jam location in this piece of junk printer




Check the spring tension of all sensor flags, and add a wrap if necessary.
another issue in this series is the wiring.

For the 010C jam code, it's typically the fuser drive clutch


I personally would remove the Finisher/
then gut the printer to physically look for any PAPER FRAGMENTS that may be lodged inside connections on Frame Side & on all Removed Assembly s---
