MX-2300N Keeps Jamming (POD_1N, H5-01)

[engineerboy93]

Picked up a MX-2300N today and it keeps jamming. When I first started the machine it had an H5-01 error. I cleared that out and tried to run a copy through and it jammed up. I ran 22-03 and it shows up POD_1N, two times. I've read from another thread that it might be a white gear on the ITB? Does anyone else have any experience with this code? I noticed the print are ready for the fuser but z-fold before the fusing unit.

Any insight is appreciated, thank you.

Check to make sure ppd1 is working properly. They are a reflective type sensor that fail quite often.

You "picked up" a machine, as in purchased from elsewhere? If it wasn't powered down correctly, chances are your fuser has a flat spot prohibiting paper from rolling past it appropriately. The alternative as you note is the main drive gear for the primary transfer belt cracking, preventing the belt from turning.

In cases of the primary belt, paper will contact it but not advance further; accordion folding is unlikely.

Thanks. I'm going to wait for more opinions and make a list of things that should be checked. Yours is on the list. Hopefully something simple and cheap. It does have a low paper count, 56k on the meter.

More than likely primary drive gear is bad.

Yep, I got the machine for free and it is all full of toner too! (100-75%) The last job stored is dated 2012.

Anyways, I checked the fuser and the upper roller appears to have a flat spot approx .5" times the length of the roller. (Added to parts list). Kudos on the roller!

I'm also going to check the white gear and the PDD1 sensor.

I've noticed one more thing, strange... It makes this thumping noise for approx 30 secs after I close the side door. The thump sounds like it comes from the internal finished, and it looks like it because the follower jumps a little with each thump. The thumps come about 1-2 seconds apart.

This ties into the flat spot on the fuser. Replace your fuser.

Makes sense. I am going to replace the roller, it appears the innermost roller is the only one with the flat spot.

Wow, just looked. The fuser unit is about the same as just the rollers. That does not make any sense, oh well it must be done anyways.

Some Sharp rebuilds don't make sense. If you can get a whole unit for nearly identical cost as a part, might as well go for it.
Fuser replacement should alleviate your jamming problems as well as your noise.

Exactly. I did find a place that has the sharp roller kit for about 100 bucks. Shame, had this machine been stored properly... Well, I cannot really complain because I got this machine for 30 dollars (fuel cost).

Alrighty, well thanks for the help. Thank you everyone, got many answers for a machine that I have ZERO experience on. I'll update this post after I get the roller kit installed (about a month).

I'm also going to check the gear and sensor. I feel that if the machine had H5-01 when I got it that probably the owners just stored it and then the fuser deformed. So probably replacing the fuser or rollers will not completely stop the jams.

The H5-01 codes are because of multiple jams in the fuser.

Yup, I checked it out in the service manual. I'm just wondering what was causing the jams, and this is assuming the roller didn't develop a flat spot until ages after the consecutive jams.

After the first jam, if not removed, than code cleared by opening/closing door, the next page through will cause a jam and then the H5-01 will pop up.
The first jam could be bad paper, paper loaded incorrectly, ??? If the customer had cleared the H5 code with the diag, then that's where the multiple H5 codes came from if they didn't correct the first jamming problem.

Code history only showed 1 H5-01, I cleared it out and ran a test copy and jammed. I checked for additional codes, POD_1N was the resultant code. My assumption is the thing jammed so many times and the customer gave up on the machine and bought a new machine. I say this because the last known job was 2012.
You're probably right, bad paper or even paper dust caused the jams. When I open the back I'll know more. Thanks for your valuable and extremely helpful insight.
