Not meant to bash... just look at everything first and the price last. If you budget shop for a production machine you will get what you got. I've seen to many people get a machine on price alone and then get burnt because it would not perform up to their expectations or future needs. There is no worse feeling then cutting your first set of business cards and finding out the sheets bounce around +/- 1mm and your margins look like a 5 year old cut them.
I don't have much problem about sheets bouncing +- 1mm. It's already the case with my CPS900 (it's even worse, it can even go up to 2,5mm sometimes. But 1mm is the norm. And I am not talking about paralelism). But I like the CPS900.
My choice is :
Reconduct the CPS900 for 3 years (it's dirty cheap and I know what I can expect. What I scare is the service, I will be one of the last on the planet to have the machine and it's going to be a problem to repare it properly, at least quickly). To reconduct the CPS900, I have to take a DP Line or a varioprint 4000. The 4000 is not bad but I am sure to have the same problem as the CPS900(be one of the last to have the machine, it's already difficult to find someone who own one). The DP line is expensive but for what I have seen, you get the best quality it's possible to get on B&W. I just wonder if it would hold the quality over time(way too much plastic to my liking, and it seems a little bit light builded).
The second choice it to take a C7000 with a KM B&W (125 pages/min). It's not perfect, and not the cheapest choice. But the quality price seems good. And I will be able to win money(I can't work at loss)on both.
The situation with the Xerox 4112 doesn't seems to improve (the quality is only getting worse over time. The specialist is going to come again(I can't count how many time he have been here, +- 20 times on 8 month). But I start to wonder what the problem is, absolutely everything was replaced recently exept the motor).
And my varioprint 2090 is really getting old. I have to replace it.
KM is warned, we have been in trial with canon in the past and they lost (for a CLC4000). Some condition will be writed on the contract.
Another solution is also possible : stop the business.
Of course, it would be nice to hold a varioprint 6250 with a DP line for the black & white and a nexpress with another sytem in back up. But I am really not sure about the volume. I prefer to work a little bit harder and be sure to pay the bill. And if things imrove, it's always possible to buy something (they struggle to sell anything at the moment)
