After a few days of good nozzle checks, the rot has set in again. For the last two days, I have had a couple of missing segments in the PK cart. Today, that moved to the R cart with about two lines missing. I then ran another nozzle check and then had about 2 missing lines in the R and PK carts. I ran an inksep which showed a blob of ink as well as the inksep. The next nozzle check was good. I pulled the carts to see if any had leaked. So far there is no obvious leak.
I think that we can conclude from this that Larry's technique is not the answer for IJM carts. My take is that IJM carts have an unacceptably high rate of air leaks.
