Black lines on MPC2800

[E Winter]

I've overread that you showroom machine is doing the same issue - that is indeed strange of course. I've checked a brand new MPC2800 and it's doing the same symptome until I set User Tools > Copier Document Server Feautures > Edit > "1sided -> 2sided auto margin" to "0"

Very, very interesting... Could you please check your firmware versions on that machine? If I guess, I'd say you probably have an older firmware version than I have on this machine, and that may be the problem... They must have overwritten something.

My versions are:
Engine 1.55.09
System copy 1.24
Scanner 1.24

Not sure which one of these that would contain the 1-2 side auto margin setting...

Edit: Oh, and those firmware versions are for the customers MPC2800, not the MPC4000. Just for comparison.

probably system copy - our MPC2800 looks up to date except scanner wich is 1.23

I've attached a diagnostic report and non-default scan:

The User Settings should look like this (photo taken from a MPC2500 but it should look the same on the new MPC series):

Yes, that's exactly how my screen looks as well... the settings I mean.

What happens if you change the 1 sided > 2 sided auto margin to 30mm? Do you get a reaction on the copies? (cause I don't)

I'm not ready to abandon my theory about the firmware though... is it possible to "downdate" the firmware, and if so, does anyone have older firmware?


I don't have the diag report and non default settings for the MPC2800 right now, but I'll attach them for the MPC4000 here.

[E Winter]

Our machine reacts like it should if I edit the auto margin value. Usually it's possible to downgrade the FW - maybe you can compare ALL FW versions with the ones on my diagnostic report and try to get different versions via tessa. We're closing in a few minutes but I have these FW versions on my PDA in case you need something via mail.

My collegue just pointed out that the older firmware versions actually are available at Tessa... and when looking at it, it seems I've missed updating system copy to 1.24 which is the newest... that's weird though, I thought I was thorough when I did it earlier today... I'll double-check it.

Thanks for your help Jan, you've been extraordinary! And have a nice weekend, go easy on the booze

[E Winter]

You're welcome - a mate is celebrating his 30's birthday so there might be some more booze than usual^^

Please get back to the thread I you have a fix or need more assistance. Maybe this is kind of an issue wich does only occure with specific combinations of different firmware-modules versions. In this case it should be fine if you update the missing parts to the most recent files.

Well it says that it is a new update from 14-10-2010 version 1.24 on system copy on tessa, but when i try to download it it says file not found. Thats aslo strange very very strange..

[Prodigal Son]

Hmm, I just started up another MPC2800, brand new, that does the exact same thing as well. I compared firmware versions to yours and the difference is:

PCL, PCLXL, Scanner and Websystem where my machine is one release newer than yours. I'm going to try and downgrade Scanner and see what happens.


Edit: My mistake... this machine actually answers to the 1-2 sided auto margin setting... I've changed it to 0 and now the problem is gone. The MPC4000 still doesn't respond to it, but this means I most probably can solve the customers problem at least and worry about our machine later.

Well then don't hold back, if you're gonna drink - go all in

I think I'll just drop this case for the weekend. I'm confusing myself with all the angles and approaches so the best thing would be to let it go and get back to it with a fresh perspective on monday morning. I believe a firmware update could solve the issue though. As usual, in the end!

Have you tried adjusting the front and back margin to 0? That is the top 2 settings in the photo. Also, try in SP mode 6006-3, adjusting your triking edge registration.

Yes. The problem isn't normal copies though, only duplex copies, and only the back side of it.

Also, try in SP mode 6006-3, adjusting your triking edge registration.

I fiddled around with it yesterday a bit, as well as leading edge SP modes, but I couldn't really nail it. Using the SP modes, I can make it acceptable, but not at all satisfying. I might get back to this if the firmware upgrade / downgrade doesn't work on monday.

[Prodigal Son]

Okay, the problem is now solved!

In the end, I had to do an NVRAM reset of all data (5801-1). I tried updating firmware, setting all non-default SP modes to the same as both our working machine and Jans, rebooting a million times, setting SP modes to their defaults... you name it. I then tried uploading the NVRAM data to an SD card, but it kept failing time after time. I looked at the card contents after a failed upload, and there was a folder called NVRAM there, and a file with serialnumber.NVR or whatever the extension was that I can't recall now - it looked fine but still wouldn't upload data.

After consulting with my support, we concluded that something clearly was wrong with the NVRAM data. So I printed an SMC, made a copy of the address book and wrote down whatever I was unsure of. After the reset, all was fine and I could even enter the old settings and all was still okay. There is no explaination at all for the behaviour... some kind of software lockup I guess... the machine actually responds to the 1 sided > 2 sided duplex auto margin too, if I change the setting, after the reset.

Thanks everyone for your assistance - you're fantastic!

Glad you've finally sorted it out

[Assumed both copiers are showroom new machines ??]

Given the above assumption :
What is the common link between these two machines the MPC 2800 and the MPC 4000 ?

With out sounding off beat. The only commonality is to check if it was the same Tech who run-up both machines ?
1. Ask the Tech how he run-up both machines.
2. Have parts been scavenged/swap from old machines into your new showroom machines.
