Just from experience... if people are having clogging after the printer
being idle try checking the capping springs, on the1160 there should be two.
Also sometimes if you have used windex on the pad this can leave a surface
of windex on the head. Try parking the head to the left before a cleaning
cycle. Maybe takes two cycles. Also from experience, the capping pad does a
better job if the head is not in the + position.
