Digital BW, The Print

I'm trying to gather some info here, not report a problem. Curiosity, 
mainly:

1) Paper feeding issues? What size/weight paper?

2) Banding issues?

3) Clogging isuues (i.e do you suspect you are getting more clogs 
running this paper then say, an "approved" Epson paper)?

4) Problems with appearance at 100%k

I'm using IP5 greyscale, but since I just sent them the calibration 
targets and got back profiles yesterday, I suspect noone else is 
running Eclipse through an 2200 with IP5.

Please tell me your environment if known, i.e. temperature, humidity, 
clean or dusty, etc. You can reply offlist or on, as you desire.
TIA,
Jim H.
