New Epson r3000 prints darker than old Epson 4000

HI Bruce.....just a point of curiosity...is OP me?  My initial problem was that this new printer did not print prints that matched the old 4000.  I agree it doesn't make much sense.  If I can figure out what you are suggesting I will try your steps.....but, it still seems like you are all saying I would do better to calibrate my monitor.  I am beginning to get a bit lost in this discussion.  I think you are all beginning to go beyond my comfort zone.  So, I need a good bottom line.  Try your steps....then get calibration equipment?
