MX-M4071 - H5-01 code

[MHeon71]

My customers copier is throwing H5-01 code with no jam codes. It occurred on 6/15 with no jam code and I flashe firmware to 4.00 (Latest firmware I had at the time). H5-01 code occurred again today with no jams. Flashed firmware to the latest firmware of 4.11.

When I say no jam codes, I mean the last jam was 5/15/23 and the last POD1 jam occurred 9/21.

The following is what Sharp suggested.

1-Check fusing unit installed 2-Check fusing drive section 3-Check connection state of sensor (POD1) 4-Check harness and connections. 5-Check / replace sensor (POD1) 6-Check / replace PCU PWB 7-Check / replace fusing unit 8-SIM 14 to cancel.

I have taken the fuser apart and inspected and everything looks fine. Harnesses look fine, as well. Has anyone else dealt with this? I am thinking more of a PCU issue than sensor or fuser issue.

Any assistance would be appreciated.

We have one with same symptoms. H5-01 with no jams. Happened almost a year apart with last week being the second time. Far too infrequent for us to spend time figuring out, we'll wait and see.

Clean the connector on both the fuser and main frame with contact cleaner.

There is a bulletin for this where they provide you with cotton tips to clean the connectors.

I have found giving both connectors a good spray with contact clearer has worked every time for me

Re: MX-M4071 - H5-01 code

Have had this a few times with this series, exact same symptoms. Our fix was to replaced the POD1 sensor. Fairly inexpensive fix after you have tried cleaning the connectors (which we do on all Sharps now).

Good luck

I have missed the bulletin on cleaning connectors, but will give that and POD1 sensor a try. It is a school, so I may not see if the fix truly works until late summer.

Thanks for the help.

I had an mxM5070 throwing random h5 codes in a lawyers office in an old house, got them to run a dedicated line problem went away.

I'll second the power. Had one throwing that code with no jams, put a line monitor on and discovered tons of faults.

Re: MX-M4071 - H5-01 code

Faulty sensor has two things that bug me.

- Same machine, two fusers. Those aren't great odds, seeing as how it's the only machine in our fleet that does it.
- Faulty sensor would still register a jam, you'd think.

Re: MX-M4071 - H5-01 code

So far so good after replacing the POD1 sensor and contact cleaner. It is a school, so I may not find out until Fall. If it returns, I will look at the power and update this post.

Re: MX-M4071 - H5-01 code

We had one that was throwing that code and it turned out to be the connector in the machine that the fuser plugs into. Some of the fine wire contacts in the connector were bent out of shape. Not terrible to get the connector out but still not fun. We couldnt really see the problem till we took the connector out and look at up close.

Re: MX-M4071 - H5-01 code

I am with JR2ALTA. Doesn't pass the smell test. If H5-01 is displayed on screen, but there is no paper in fuser, and there are no jams recorded, and sometimes the H5-01 itself isn't logged, something is wrong with software maybe. I am not the sharpest knife in the drawer, but that's what my money is on. For us, this is not a onesie twosie thing. Numerous machines doing this over several years now. Many times fuser is replaced and firmware updated. Still comes back. Each new fuser brings a new POD1 sensor and new contacts on fuser side.

We don't have a line monitor, so cant say for sure on that. My gut tells me that most cases are not that. All these machines are supposed to be on dedicated circuits, but few are. I see copiers on full power strips that are fed by other full power strips, or on extension cords. All working fine with no bogus H codes. The absolute dirtiest place we service copiers somehow doesn't have these codes. Since the bulletin on cleaning contacts came out, I have particularly eyeballed the contacts, and have never seen any that looked like a problem. Would like to see pics of these problem contacts just for my own education and curiosity. Sharp has used this general type of fuser contacts for a long time, so why do they all of a sudden have to be kept pristine.

Sorry. No answers. Only questions and frustration.

Does the machine have a punch-unit?

Has anyone found a solution for this? I've had this same issue on this one machine (mx-5071) for years now, H5-01 no jams recorded and users report it never jams. I'll clear the code then it comes back in a month or so. I've replaced pod1, fuser units, pcu board and even the fuser wiring harness. Today I'm trying a CN update to hopefully take care of any firmware errors, Tech support recomended replacing the fusing unit(again), fusing drive unit, loosening all wire guides on pod1 and the fuser harness but it seems like they are just as lost as me.

[nanohitmen]

have you checked the 23-02 to see if it's being caused by PRI_Jams? Had a similar issue due to clients software not behaving with the MFP.

Is the customer rebooting the copier regularly ?
