Digital BW, The Print

I can't say I've had anything exactly like that, but I did have a similar occurrence with a different printer.  Of course, the first thing I'd check is that the refill was correct and K was not put into the midtone positions.

The inconsistencies I've recently dealt with concerned the 2 1400s I've been running from the same computer.  There seemed to be random, suddenly different printing characteristics displayed.  I suspected it was the drivers.  So, I deleted both of them and downloaded a new one from Epson and hooked up only one printer.  The random inconsistencies (mostly) disappeared.  

(The remaining random differences appear to be different in nature and relate to the inability to get totally consistent B&W output from color inks -- thus the minimum 50% K profile noted in my previous post.)

So, if both C88s are driven from the same computer, consider a fresh, single driver, and see if it has any effect on the problem.

Printing continued normally after each of the first two refills. But after the third one, BW2 immediately began to print MUCH darker than BW1 - in film terms I'd say probably two and perhaps three stops darker.  After an overnight cooling off period the results remained the same this morning.  So I swapped the BW2 EZ carts with the third C88 (C88 Color) I have that normally uses regular Epson OEM color carts.  After a couple of cleaning cycles and a purge print to get a good nozzle check, that printer now prints just as dark as BW2 did.

But I'm wondering what it could be?  Has anyone else had this experience with the EZ inks in a C88 - a dramatic and instantaneous change in density?
