I just got back from a 10 day business trip and Left Harvey on to take care of business. I am happy to report no nozzle drop anywhere. While I was gone temperatures outside were in the 90's and humidity inside was around 35%. Before this would have done BK and LLK in.
I took a fellow readers suggestion and purchased a 36" roll of standard printing paper and cut it into 10" wide rolls. I did a no cut on the machine, marked the original date on the first test pattern and when I got back, I had a nice ribbon of successful test patterns.
I was concerned that I may have needed to print something more than a test strip to keep the nozzles cleared. Like printing a picture every third day, but so far the test strip seems to do the job.
