MX-7001N Printing Issues

[Dustin(WOP)]

I have a strange issue, on print only it goes into automatic callibration about every 2 or 3 prints and started right after a paper jam in the fuser? Does the jam have anything to do with it? They also recently installed an ES1000 color callibration tool. It is not going into callibration when they are copying, only on prints. Anyone have any ideas on this?? Thanks!!!
Also they do have MX-PEX2 installed and the HDD says that there is only 2Gig available, however there are no documents stored in there that I can see. What is going on with this?? PLEASE help!!!

Weird one!

First confirm that the fuser is OK. All thermistats are not tripped and there is no paper stuck inside blocking the non contact thermistors. A known issue with machine stopping & saying ' please wait machine automatically adjusting' could be caused by the fuser losing heat and trying to warmup again after a few pages. There is enough heat in the fuser not to cause any H3/H4 codes, but not enough to maintain continuous printing.

This is more than likely going to be a fiery issue, especially if you have a color calibration tool installed. The machine very well could be performing process control to restore toner density between prints. How are the consumable levels? When was the machine fully serviced last?
Run a full colour calibration over the machine in sim.
Perform a system software reload of the fiery (last resort).
You can always disconnect the fiery controller from the MFP and test just using the standard print controller. This will rule out the fiery or engine causing the problem. I've had to do that before in the past. A continuous print test using the standard print controller will immediately show any problems.

This is a weird one. We have a few fiery's out in the field, but never heard of this. There is also nothing in any bulletin on this symptom with this configuration, or any firmware upgrade for the PEX2 that would help.

I'm still thinking.......

Print out the configuration page from the fiery. Check all settings are OK.

Are there any system codes on the side panel of the fiery? It should say '00'. Other codes indicate faulty memory, HDD or main board.

The HDD is used for spooling of print jobs. Unless the print jobs are extremely large, I cannot see how this could be a HDD issue, but the PEX2 & PEX3 both have 80Gb drives installed. I'm not sure if you are looking at a storage partition or the whole drive capacity when you've mentioned only 2Gb remaining.

I'm still thinking this is more of an engine issue. You really need to test the engine by itself without the fiery connected before anything else drastic is done.

Pm was just done on all drums and Devs. I have attached a 22-6 and fiery configuration sheets.

Just a follow up on this problem. Dustin and I were working together on this. After many hours of troubleshooting the problem, what we found was a flat spot on the reverse roller in the LCC. This shouldn't have given us the problem we were having, but it did. What I don't understand is why we never had a misfeed. It would just stop and go into auto adjust mode, then continue printing. Wazza we did check all the things you mentioned, because they all made sense. What we found doesn't make sense to me, but new rollers fixed the problem. If anyone knows why, please let me know. Thanks for the input.

Well aint that the craziest fix ever!

How could a worn PF roller set cause that? You got me stumped there. They look like the original roller set (185K according to the 22-06 printout), so at a 200K life thats not bad.

P.S. Upgrade the saddle unit firmware. There is a special edition for the saddle unit on the FNX4's to give better folding & jam prevention.

Other than that..... well done on the weirdest fix ever! Although logic tells us all that there must be something else going on there....... who knows.
