Digital BW, The Print

The cleaning that I'm referring to are the ones after chip resets 
(auto reset chips in the CIS) and the ones that the printer does 
itself from time to time.  I.e.  the ones that you simply can't 
prevent, even if you leave the printer on, as I do.  The timing is 
therefore random, and always occurs just as I am about to do a burst 
of printing.

Sometimes an auto head clean is the best way to deal with this, 
because purge patterns don't seem to make an impact.  However on 
other occasions the auto head clean makes it far, far worse.  Then 
it's a case of waiting for a day or two and doing purge patterns.

If it's a case of freshly refilled carts, I suspect that you'd be 
better of waiting a day or so to let the bubbles rise and then 
printing a purge pattern or two or three.

For a CIS, especially on an 8 cartridge machine where resets are 
frequent, as there's always one chip about to reset, I had wondered 
about the benefits of switching to manual reset chips and resetting 
the lot when one is "empty".
