Digital BW, The Print

I'm using Mis EZN carts in the C86.

Should I leave the power on when not in use, or power it off with the 
C86 power switch?


(All of my other Epsons with oem inks I leave powered on constantly 
and never had a clogging issue).


I "cured" the SLIGHT banding problem by turning off the "High Speed" 
feature in the Epson print driver.

I've only printed 3 8x10's and already I want a CFS unit.
Or, re-fillable carts since this printer will only do 8.5x11".
