Digi - Xerox was never able to get our machine(s) working. My advice to you would be to do the following:
1.) Run a test on a demo machine that is not in the Xerox office. They usually tend to look a little different then engines in the actual field. Find somebody in your area that would allow you to run a couple sheets off as a test.
2.) Choose a past job that is color critical and test the machine on that file, or multiple files.
3.) Keep the sheets in printed order and cut them down. Do not stack them, keep all cuts separate.
4.) Fan out each individual cut pack and check to see if there is color swing. Then put all stacks together and fan out again. If the machine is working "properly" there should be little (and I mean LITTLE), to no color swing.
5.) if you have color swing on your samples, pick a different machine.
I will tell you from my experience, the 7002 (I had 2 of them in here, and the both did it), the 8000AP, and the 700 all have color issues. I replaced the Xerox machines with a
KM 6501, and couldn't be happier. It has very, very, very minor color swings, but not sheet to sheet. I see slight color changes from sheet 1 to sheet 1000, which is completely exceptable.
The 8002 is basically the same engine as the 7002, only a little bit faster. For the price, if the the 7002 has in fact been fixed, it is not wirth the extra money to buy the 8002.
If you are a high quality, color critical shop with jobs for agencies or high end clients, I would recommend running extensive tests. Do not base you decision on the samples Xerox will give, or have goven you. They are doctored to look perfect.
I would be happy to give you a couple files thta i used as test runs if you need something that will show the defect if it is there.
They claim to have remedied the problems, but throughtout my hellacious dealings with Xerox, you can not believe everything they say.
Please contact me if you need more informations, or would like test files.
Good luck!
