MXM1100 - Damp Paper

[Oldslap]

I am having problems with jamming due to, i think damp, paper. It works fine when a new ream of paper is installed. I have also shown the customer condensation in the machine.
When i used to work for Canon we had damp meters to prove damp paper. Does anyone know where i can get one?
All the ones i seem to find on the webb are not really for paper, or are a fortune.

My FAVOURITE machine of all time!! I have been waiting for a post on a Hercules machine.

I look after a fleet of these machines and love them to bits!

I know exactly what you are saying about the jams & the condensation in the machine. Are your jam codes POIND_N by any chance??

I have one client in particular where it gets extremely cold overnight and they have alot of condensation issues in the exit guides after the fuser unit. They were getting ALOT of POIND_N jams when using Xerox Performer Plus paper only. POIND_N jams are when the paper sticks to the drum, passes under the drum pawls & ends up wedged into the process unit or cleaning blade. There is a bulletin on a new Transfer Belt material to help hold the paper down, but all the machines we have, already have the new part number. I even tried adjusting transfer bias voltages to help hold the paper down, so it didnt wrap around the drum. It made no difference.
I attended this particular machine one day with another brand of paper and the entire box was used without a single jam. We put the Xerox Performer Plus paper back into the machine and it jammed within the first 5 sheets, over and over again. The client has obviously changed to a different brand of paper now and the 1100 is working great. They continue to use the Xerox paper in their MX7000N's quite fine.

If you are getting POIND_N jams, try the following:
Make sure firmware is completely up to date, try a different paper brand if possible, Remove the LED fix holder of the PTDL, change 55-01 sw5, bit 5 from 0 to 1 and install the new modified drum separation pawls (PTME-0342FCZZ).

Basically, from what I have seen, the condensation issue is definitely paper related. I have some machines that have never had any condensation in them, even though they are located in a cold, damp basement, but they are using a good quality paper. I have some machines in similar environments, using either Xerox Performer Plus or some cheaper branded paper, that has alot of condensation issues and jams.
My advice is firstly change the paper and do the changes listed above. It has DEFINITELY worked for me. If you have no condensation problems from the paper and using a paper which doesn't wrap around the drum, this machine is a beast that will work great for a long time.

Thanks for the reply - yes they are mainly POIN_D jams.
I have a updated belt on order and will carry out your suggestions. I have had a 950 with the same jam & that was their paper.
This customer have been using this brand of paper for over a year, so it's all a bit awkward.
Cheers

Cant stress enough that the problem with POIND_N jams is the PAPER! Have tried several brands in different Hercules machines. Some work flawlessly, some fail within 5 pages... and will continue to fail. The adjustments and changes to the machine I mentioned will help and/or fix your problem, but some problems will still remain if you still get at least 1 POIND_N jam. Have not seen it for months now, but I definitely know what it is caused by.

Get your client on a different paper and you will have no further POIND_N jams. All of my Hercules machines are running paper that works, and we have no complaints about the machines.

Its as simple as taking a few boxes of better paper to your client and getting them to use it. They will soon see that the machine works fine. Just be diplomatic & realistic.

Oh, I highly agree bro! MXM & MX series machines = best thing Sharp has ever done!

MXM 1100 POIND_N jamS

Hi Guys, we have just installed an MXM 1100 and it has this jam code on it. The machine has done 4000 copies! As you can imagine, I am a little sceptical of the "Its the paper" arguement (I know, "Oh ye of little faith). But is it that simple? It has the latest firmware (came with it but i updated anyway).

[OMD-227]

Hammer,

Trust me mate.... its the paper.

Make sure the Transfer Belt part number ends in Z2. You will find Z2 written on the underside rear of the belt. Turn it by hand until you see it. Thats the latest part number.

Cant do anything else. Perform the changes I mentioned above... it might help with your paper type.

MXM 1100 Damp Paper

Hi Guys, i would just like to update you on the issue i had with POIND_N jams. This was a brand new machine and would jam after 4000 copies. Then jam intermittently after this. Most jams were recorded at POIND_N but a couple of jams at various locations. Turned out to be the registration motor. After the long run, the motor would get very hot and become very tight to turn. This tightness would slow the pages down, put the timimg out and register jams at the various locations, generally at POIND_N. Changed the motor and the machine is running beautifully.

MXM1100 POIN_D jams

Just visited my problem machine with two of Sharp's finest. It does appear to be a paper problem as suspected. The paper is damp as well. We have lowered the fuser temp to 180 from 190 - this seems to have made a difference.
It has been recommended that they try different paper that is not Eucalyptus based (there current paper is) and suitable for high speed copiers.
Time will tell!
They did tell me about the reg motor problem - they think it was a one off, but it is worth remembering.

MXM 1100 Damp Paper

Oldslap, are you in Great Yarmouth? Chris was mentioning he was going there on Thursday to look at a problem, and that he was bringing one of the lads.

[OMD-227]

We haven't had a problem with any of the rego motors as yet, and most of our Hercs have done several million now. On each occasion of POIND_N, it was definitely the paper causing all issues.
A different, not neccessarily more expensive brand of paper, totally fixed these issues.
Will keep the rego motor issue in mind though.
Thanx guys.

[Oldslap]

Yep, that is me!
