Digital BW, The Print

The patterns of clogging I've had with the 1800 seem to relate to having the high load MIS 7600 or MP-PK next to MK.  The MIS K4-PK seems much better in this respect.

Also, I've had a number of MIS carts develop leaks in the outlets that causes a bubble to form there.  With this air bubble above the outlet the nozzle check is often worse after a cleaning cycle -- very frustrating (and one reason that printer is moth-balled).

I've seen no evidence of clogging being caused by reactions between the simple C6 base and any of the inks we usually use.
