QTR-Quadtone RIP

Hi Myron

There are a number of factors affecting the performance of CI systems.

One of the most common problems with cheap CI systems is the quality (or lack of it) of tubing used.  Ink can evaporate through osmosis, causing air pockets within the tubing.  Additionally, the inside of the tubing wall can be rough, leading to a "thrombosis" condition due to the adhesion of small ink particles on the wall of the tubing, and eventual clogging.

It is important to use quality components when making a CI system, especially when it is intended for long term use and when there might be periods CI inactivity.  CI systems are at their best when used constantly.

I have tried two different CIS systems for my R1800 and 2200, both 
eBay cheapies (but more than Paul's $50!).

Both seemed to work well for two or three months, after which I could 
not keep the supply tubes filled with ink.  Even with repeated priming 
and repositioning the supply bottles, air would leak into the tubes 
and eventually cause problems.

In both cases the problem arose in late winter, after several months 
of low humidity in my house, but I can't see how that would break the 
seal either around the attachment to the head or around the supply 
line attachment to the damper/cartridge.

I'll probably give it another try this year, though...  hope springs 
eternal.
