Digital BW, The Print

Hello all,   I am new to the forum.


Just bought an Epson R220 printer to use exclusively with B&W MIS 
inks.  

For times when the printer will not be used for a period of time, to 
prevent clogging problems I was thinking about cleaning the system 
before hand.  Paul Roark mentioned buying some spare empty cartridges 
to keep on hand. I was also thinking about some cleaning fluid also.

Can anyone tell me where to buy spare cartridges and cleaning fluid for 
this printer,  and what would the proceedure be for cleaning the system 
with the empty cartridges and cleaning fluid.

As well, is there anything that has to be done before switching an 
Eboni black cartridge with a Photo black. Or is it just a simple in and 
out proceedure?


Feedback much appreciated

Michael
