Which MFP to choose for intensive and inexpensive printing?

Question

Seal

Gentlemen, the topic has already been chewed many times, but I did not find suitable answers for myself. It is necessary to choose an MFP for intensive use (about 20,000-30,000 pages per month). Budget 30-50000 rub.
I rush between ink jets with CISS and laser ones. The main criteria are the low price of a print, the possibility of refilling cartridges, additional paper trays are desirable.

Answer 1

In fact, you have to start over :).
What and how much are you going to print?
How many are you going to scan?
How much are you going to copy?
How critical are print stops?
How evenly, over the days, will the load be distributed?
After answering these questions, you can begin the selection of equipment.
