[Jamming] MXM450N intermmittent jam in duplex and paper making noise

[rayjeek]

I have MXM450N which occassionaly jams. What happens is that the paper makes noise in the ADU, lower part as if it's been obstructed but feeds ok in duplex. However, after few successive duplex copies with the noise produced by the paper it jams with a paper stopping on ADU transport rollers. AINPD_N jam code. We have changed AINPD, APPD1, APOD sensors in the duplex unit with no positive result.
Anyone coming across above should please help.

Re: MXM450N intermmittent jam in duplex and paper making noise

i faced a same problem before.Can you tell me the total meter reading?my client got mx-m450n and complaint that paper jammed (when duplex copying)only in the morning. but afternoon is ok. i visited many times and no luck. i changed ar-du4 whole unit, cluths, main drive motor, pod sensor , paper exit roller , upgrade latest firmware and no luck.
finally, i found the problem. i change the delivery frame unit and every things fine, work until now ...
The delivery frame deformed and cause the paper exit roller(NROLR1315FCZ2) just touching the paper exit follower(NROLP1296FCZZ), they not strong enough when pull the paper back to ADU and ainpd sensor detect late reaching.
afternoon is ok, possible the heat from the fusing make the frame expanded.

Re: MXM450N intermmittent jam in duplex and paper making noise

I would look at the meter also. With the jam code you are showing we almost always wind up repalcing or rebuilding the turnover assembly. Is the paper that is just entering the duplex until crumpled like it didn't make it over the guides?

Good luck.

Like Bil says. This is an old problem going back to the AR-M280's. Replace the delivery/turnover unit. =^..^=

Thanks so much for all your contributions. Will change the turnover/delivery unit.

changed turnover delivery unit today but still having flapping noise caused by paper just around lower ADU transport roller. it jams occassionally with paper stopping in ADU unit when this paper noise occurs. Anymore ideas, please help.

What's the new jam code? =^..^=

Re: MXM450N intermmittent jam in duplex and paper making noise

Not sure how close this is to the AR-M455 but the paper detect switch in the lower part of the ADU may need an extra turn put on the actuator return spring. While doing that, clean the sensor for the same switch.

Not sure how close this is to the AR-M455 ...

Mechanically identical. Electronically, different boards.

Re: MXM450N intermmittent jam in duplex and paper making noise

The new jam code are AINPD_S, or APPD1_S. Paper always stops in the ADU unit on the transport rollers just after the flapping noise produced by paper.
Every sensor/switches have been changed on the ADU. More ideas needed.

Re: MXM450N intermmittent jam in duplex and paper making noise

Two additional possibilities:

Misfeeds (jam code POD2N, AINPDN) in the delivery/turnover. The diverter gate has a 2mm warp, down in the center. Paper cuts are visible toward the center. Toner chunks stick to the diverter gate in the upper left side door. Replace the diverter gate.

Misfeeds (jam code AINPD_N, APOD_N). The trailing edge of the copy gets snagged in paper cuts in the inverter gate when the paper is being inverted for duplex or face down delivery. Replace the inverter gate.

Re: MXM450N intermmittent jam in duplex and paper making noise

I know this is an old thread, but can anyone tell me which manual I need so I can find the part numbers for the turnover unit, diverter and inverter gates for an Imagistics IM3511 (MX350/450). I have a manual I bought from Paul but it seems as if there are several different manuals for parts. Any help is greatly appreciated.

The MXM350/450 manuals come as one piece, the ARM350/450 manuals were broken up into the individual options that made up the copier. If what you're saying is true, the IM3511 is more closely related to the ARM series, in which case you would need the ARP350/450 parts guide as that was the base printer model of this Frankenstein copier sans scanner, duplexer, finisher etc...

for im3511, please refer to ar-m355/351 part guide.tthey are same, just different dv box, drum unit, and thermistor.
