Ricoh MP C3300 ADF jams

[jonbonse]

Hi all

A client of ours has an MP C3300 and the ADF keeps jamming just after pickup.
It has new rollers, belt and clutch.
I have tested the reg sensor in SM and all seems ok.

Can anyone help?

Are you getting J53 ADF 3030 Error?
Try replacing these parts:

A294-6700 Sep Clutch.
D541-2241 Sep Roller
AX21-0102 Pickup Mag Clutch
AW02-0141 Input Photo Interrupter.
B789-2114 Feed Belt Roller Clutch
D541-2121 Feed Belt

Now it's mainly J003 jams when copying one simplex sheet, the paper stops as it is half way out the document feeder.

I have tried all the parts in the last post. . . .

I understand there is a bulletin for these jams? Has anyone got it?

Check if all sensors and the reflection areas are clean. It's usually paper dust causing misdetections of paper during operation.

I have cleaned all sensors but not seeing any 'reflectors'. . . .?

Does the machine issue a jam warning or paper mismatch? Check that the original stopper is engaging and disengaging correctly, if it doesn't engage properly the paper can be pushed past the pickup roller or just past the original length detection sensor and cause a mismatch.

You could have a one-way bearing slipping - just saw this yesterday for the first set of transport rollers, which caused a jam "just after pickup" as you described. While turning the transport rollers clockwise by hand, every once in a while I would feel it slip rather than friction. Slid the one-way bearing down to expose the shaft underneath it, scuffed it up with Scotch-brite, and all was well.

Thanks all

The ADF will copy fine if I have more than one page to copy but it always jams in the same place with jam J003 on the very last page.

If I put one page in to copy it will jam in the same place again with J003. . . . .

Sounds like sensor lag on the trailing edge sensor.

Something else to watch for.
The top cover closed sensor may be toggling. I believe it's at the rear on this machine. Use a small rat tail file an make the "metal sensor bracket hole elipse" then move it closer to the cover flag/tab.

People push the top cover closed from the center. Over time I believe the cover becomes concave and the close sensor misses the flag.

I seem to remember having an issue with some warped guide plates on one of these.

Good assessment, on a BH250 u need to put extra weight on the flag to make it fall back quickly enough. Change the sensor with the flag, or try using a wee bit of lubricant to test for that but thats not a good long term fix.

My bad - the paper itself is the reflector while passing by some (none actuator triggered-) sensors. During standby these sensors light into some sort of black housing absorbing the light. If there's too much paper dust it might trigger false alerts during operation.

Re: Ricoh MP C3300 ADF jams

Your problem will be the Original Detection Sensor (AW020141). Go into SP6007-009; Paper Present (Bit O reads "1"; NO Paper Present in Feeder Hopper (Bit 0 reads "0"). Your sensor is not changing back to "0" after the paper feeds - it will always show "1"; hence, if you have 1 original it will feed part way out and show a jam, BUT if you have 3,4,5, etc originals it will always show the jam on the last page through the feeder. Could be the sensor or the sensor flag (under the top cover)hanging up in the cutout area for the sensor.
