Mpc3002 with no feed from ardf

[CraiginAK]

Having issues with a MPC3002 that most times lately will not recognize paper in the ARDF3060. Supposed to get the beep when paper is put in but no beep and thus no feed. It will just copy from glass like nothing in doc feeder. Occasionally it will beep and then it will feed fine but 9/10 nothing no feed. It knows when lid over df tires is open and in test mode can get most things run but the p/u rollers. I've checked the two things on df that let the copier know its closed and they both are doing what supposed to not knocked out of position. I just updated firmware which I figured wouldn't help but thought might as well. Any suggestions be most welcomed.

Did you check original set sensor?

I was just on a MP C2050 today with the same symptom. Short blast of canned air in the original set sensor - no more problem. Damned dust getting into doc feeders.

I did clean the original set sensor and tried checking in test mode but couldn't get it to register when moving arm. However not sure if this is result something else or just sensor being bad. Going check book tomorrow see if another one like it in feeder so I can swap it for testing. I'm assuming its the one on bottom towards back that the paper pushes the arm into when placed in df.

It is the one where the feeler arm hangs down from the feed cover. The paper pushes the feeler out of the sensor just before it gets to the stopper. The one in the paper table is the trailing edge sensor for the last original.

Re: Mpc3002 with no feed from ardf

Yes that's the one I cleaned and as far as I can see as paper goes in it pushes arm into the original sensor which it is doing. The trail edge sensor is same as is couple the width sensors so will try switching around see if can get any where with this thing.

Wouldnt the sensors at the rear of the df that detect the adf is up or down - the sharkfin ones - do this also? pretty common for them to break off....Im just not sure off the top of my head if they would stop the machine beeping or not....

Re: Mpc3002 with no feed from ardf

I think it could but this one is intact as is the other one on other side on bottom that tells lid is down.

I hope you checked that the cable coming out of the doc feeder was properly connected to the machine.
And maybe double check that the actuator for the sensor that detects when the document feeder is closed is in good shape.

Re: Mpc3002 with no feed from ardf

Yes checked connector and it seems to know when df is closed and opened so I think those sensors are working. Going try switching around some sensors tomorrow see if can figure out what's going on.

Try an input check on the original sensor (SP 6-007-9) and make sure it is doing what it is supposed to when you load paper. The fact that you dont get a 'beep' tells me the original sensor is not working or the flag that hangs down is not doing its job.

I missed that in your original posts, sorry about that.
Sounds a little bit like the cable that runs between the doc feeder and the machine is going bad (metal fatigue in the wires from opening and closing the doc feeder) or maybe the the circuit board in the doc feeder is failing, but I've only seen either of those happen once, and only on older machines. So that's kind of unlikely.

Re: Mpc3002 with no feed from ardf

I have the exact same fault, what was your fix please?
The fault is intermitent, i've fitted a new original detect sensor.

[CraiginAK]

Re: Mpc3002 with no feed from ardf

Yes the original detect switch seems to have fixed it. I haven't heard anything back since changing it.

The original detect switch, do you mean the photointerrupter?
