Xerox 5000 banding

[gtcrshr]

Hi guys, just found this forum last night and it has a lot of usefull info so maybe some one can help here,

we keep getting uneven colour from the top to bottom of the sheet

for example if i print a purple solid it with be fine in the middle, then look redy/pinky on the two outside edges,

what should i be telling the tech's to replace ? they keep saying its as good as they can get it, is this normal ? am i expecting too much from this calibre of machine !

many thanks and thanks for a great site!

You shouldn't have to tell the tech's what to replace. Just show then the samples and they SHOULD be able to determine the problem(s) from that.

Now if they are telling you this is normal I hope you have a copy of the CED that SHOULD have been given to you (or someone from within your company) at the install. If the 5000 is not performing up to the CED then they need to... 1 get a specialist in to get it fixed or 2 replace the box, just ask the tech about the TOTAL SATISFACTION GUARANTEE.

Hi, thanks for the reply,

i am from new zealand if that makes a difference,

what is a CED ? we never got given anything at all to refer back to,

If i dont tell them what i want replacing all they do is clean them and put them back in, i had to ask them yesterday to put a new fuser heat roller in, this company is run by accountants you can tell !

this is the last machine we will be getting from xerox, have been with them for 12 years and justbeing treated like cr*p now, but thats another story!

CED = Customer Expectations Document. That is the Holy Grail to what Xerox will guarantee your machine will do.

1 - Is your tech from Xerox direct or a dealer?
2 - Does he plug a laptop into the 5000 to communicate with it?

If the answer to 2 is yes then he should see red in any ware part that has reached the life expectancy in the 5000. That means that part need changed, no if and or butts about it!

Do you have your own parts on the shelf? Do you have Charge Corotrons? Have you changed them lately? How much volume do you have on the 5000?

Demand to have a specialist come in and FIX the problems if this guy isn't, call his supervisor and your salesman and let them know about your dissatisfaction with service. Don't pussyfoot around.

From what I gather this is a feature of the 5000. The AP may have resolved this issue but a xerox tech told me they could resolve it until the power got recycled.

ok well thats a new one, never had anything like that from them, but do have the first prints that came off the machine,

gonna kick up a bit of a fuss if this isnt normal (i didnt think it was to be perfectly honest)

only done half a million, from brand new, so a new machine basically,

in answer to your questions , yes straight from xerox, and yes plugs a laptop into it,

there are a lot of problems with this company here, they have been voiced but fall on deaf ears ...

dont have parts like that on the shelf but i can tell them to put that in if you think that would help ?

basically the next step is to get the service manager on the phone and have a go untill they send some one who can fix it, !

can you explain more ?

That isn't a feature of the 5000, it's a service issue. Do you mean by top and bottom of the sheet the lead edge and tail edge, or do you mean the operator side (bottom) and the non-operator side (top)? If it's a lead and tail edge, are you running a auto duplex job? What kind of paper are you running?

My first few guesses would be a fuser issue, developer housing issue or a laser issue. I have a test sheet that I've made that is 11" x 17" with 4 boxes on it, 11" tall and 4.25" wide. Each box is a 40% tint of C, M, Y & K. I run a couple of these through to see if it's a specific color that is creating the issue, and where it is.

I'd be on the phone with the service manager by now if I was in your shoes.

gtcrshr,
Charge Corotrons are a user replaceable item, just like Toner, Waste Toner, Fuser Web and Fuser oil. Go onto Xerox website and download the Corotron test sheet and run it off just for fun. If you see banding in the individual colors you more than likely need to change the corotrons. If you don't have any on the shelf you can switch them around. In other words if you see banding in Magenta but not in Cyan, switch those around and see if the banding shows up in Cyan, and goes away in Magenta you had a bad Corotron.

When you call Xerox for supplies, please make sure you order Charge Corotrons, I keep 8 on hand all the time. They are part of you maintenance contract just like Toner.

One of the other parts that I have had banding show up in is the Drum Module, this is only replaceable by the tech. and you should have 4 of these on hand as well. According to my tech, there should be no car parts for him to haul around. I have every likely part required to make my 8000AP operational on any given day.

Again, if you are not getting the required service keep going higher up the food chain until you get results. Each time you talk to someone make a point to ask who their boss/supervisor is and how to reach them before you hang up.

Xerox service in my experience has been second to none, they don't play around when it comes to the production boxes. The only time I have been down longer than a few hours was when I had 2 of 4 brand new drum modules fail. (I now have 6 on the shelf) On day 2 my service guy brought in a specialist and after several hours on the phone with Rochester NY with the lead xerographic engineer they were able to track it down. The engineer at that time was in the process of clearing her calendar of to fly in the next day to get it resolved. 2 1/2 days is the longest I have been down, most of the time I am only waiting for 2 hours on a bad day..

Keep up the pressure!
