Digital BW, The Print

Shall I answer,

this was not a very encouraging letter - can You do the thing for me,
I'll be happy! But as You don't have a CFS/CIS yet I think I can give 
you some advices after building three of them - mostly MIS parts and 
tools.
Piece of a cake if you don't have the thumb in the middle of your 
hand - it will then take some hour longer.

Your Questions and Statement are so many - and thanks for all Your 
advices - I'll think of it when I build my fourth system.

Remember - I have had no problems until now!!!!!!
I look after my babies!

As you seems to know all the solutions I leave to the readers to 
judge! 

And - for your information - I just wrapped the bootles in a 
plasticbag and put a damp cloth in there - it was in the beginning - 
it looked awfull. I have never had the intension to wrap /smile/ my 
whole printer in a big black plastic sack and throw a damp towel into 
that sack - I'm not that sick - ........
And I did use the vacuum method for my pigmented inks - all of them..
It worked well and was clean....

Talking to me could You plese higher the
standard of discussion --- there is a little problem here!

And all Your woories - take it easy - I have it all in mind.
It will not be easy to find the "RR" tubes - But for sure I shall 
have them! I have started looking and have contact with Saint-Gobain -
The whole day went for that!

AND yes I repeat again - I ruined one of my 1290's by putting an 
black cartrige in my Quad 1290 - I took the ship of it for a new set 
of CDF/CIS carts - but I have already ordered a new one I'll have it 
next week - I can afford it - but remember - I was very tired after 
looking for the error "NO BLACK INK AT ALL"! And was angry finding my 
black tube full of grease - at the moment I was black up to my elbows-
---- now repeated again ----are you happy now my friend!/smile/
I'm rather human you know and it's on my account! My pleasure!


You could of cause not do such a stupid thing!


Best Regards to you all
