Digital BW, The Print

Has anyone else noticed  / wondered why the vent holes on the MIS pre - 
filled and Virgin carts for the 1280 are at the "wrong" end? Meaning, 
they are on the opposite end than on the Epson OEM carts.  In this 
configuration I have wondered if the vent holes are being partially 
obstructed by the spring clamps on the underside of the cartridge lids 
inside the printer that hold the carts in place. If the clamps obstruct 
air flow in any way in could effect ink flow. Hence, potential nozzle 
check problems, banding.. etc.

  My guess this is the main reason why Epson puts the vents at the other 
end of the carts.

I don't think there is such a thing as "partial obstruction". The vent
holes just have to infuse 12 cc's of air over the life span of the
cart. Either they are sealed or they are not.
