Digital BW, The Print

Hello,

For some weeks I am printing with  K4 inks (Epson R2400)and Ink 
Republic CIS system.
I print daily, but the yellow head is clogged constantly. I don't know 
if the problem is the K4 yellow ink or the cartridge( I have changed 
it several times). Now I fix it,  warming up the cartridge and the 
tubes, with a hair dryer and it gets solved the problem for some hours.

Somebody that he use K4 inks with MIS cartridge can tell me if he has 
some problem with the yellow ink?

Thank you.

I doubt it is the ink. It sounds more like a problem with the way the 
tubes are arrainged. Warming the tubes makes them more flexible, and 
might temporarily allow ink to flow, but when it cools might close 
again. Have you sent an email to Ink Republic yet?

Since this isn't really a technical group, I would suggest that this 
discussion be taken to the printers and printing forum at 
http://forums.dpreview.com/forums/forum.asp?forum=1003 There are a 
lot of Ink Republic users there, so one of us should be able to help. 
You might want to take a picture of the tubes and "carts" to help see 
if there is a problems. The other thing you might want to look at is 
if the printer top cover is pinching the tubes, try printing with the 
cover open, and don't ever use the tubing clamps to lock off the 
lines, this can cause a permanent crimp in the tubing if they are 
left clamped for too long.
