Both printers have a 4 picoliter drop size so I don't think you'll 
have any better luck switching.
 When you say "climate control" is this an air conditioner or 
something that can control humidity? If it's the former it may be 
turning your room into a dessicator thereby drying out your inks. If 
it's the latter and you can control the humidity I would check to see 
where it's set. 
As far as fixing the clogged nozzles goes, have you tried the more 
extreme measure I gave you last week? From what I've read in your 
replies it sounds like you initially had a drying clog in the black 
that got compounded when you you reprimed the CIS system-then all the 
channels shut down -am I close? So what your dealing with is an air-
locked and clogged printhead. 
Most remedies you've been given will only handle the clog or a minor 
air entrapment but not both. You'll either need to do something a 
little more extreme or have the head fixed at a shop. Since your at 
the point of replacing it anyway you can't make it worse right? So 
this is what I would do: Take the carts out of printer and attach 
tubing filled with flushing fluid or a 50/50 simple green/distilled 
water mix right on the printhead port. Make sure there's no air in 
the tubing. This is really easy if you have a syringe. Then use 
GENTLE pressure THEN suction in a back and forth manner just like you 
would do to a clogged toilet. Keep at it until it feel like you can 
push fluid though the head-try and get 2-3ml though. Do that to all 
the offending heads. Then put OEM carts in and check your nozzles. IT 
may take a few head cleanings to get everything going. If that 
doesn't fix the problem the printer is beyond help and you can 
confidently take to the shop and say its dead. I've done this with my 
3000 and it works 2/3 of the time. It depends on how bad the clog is. 
But when works it works great.
