BN-20 print head questions

Post by SEW » Mon Feb 23, 2015 4:19 pm

I have a couple questions regarding the BN-20 print head and life expectancy.

The BN-20 uses, as far as I understand it, one (1) DX7 print head using 8 channels with 180 nozzles per channel (so 1440 nozzles in total) and a maximum dpi of 1440?

What is the average life expectancy specification (in dots per print head or dots per nozzle?) for a BN-20/DX7 print head, assuming standard operating conditions and standard maintenance, please?

Also, as far as I understand it and calculated, CMYK usage of the BN-20/DX7 is about 0.005 cc/inch^2 for C and Y and 0.01 cc/inch^2 for M and K (rectangular print area, single "colour" use), respectively?

Thank you very much in advance!
