I have had a 4880 for years now and until very recently did not use the printer a lot.
We have now been putting the printer through its paces and have been using it for production of album spreads.
I have noticed that the flushing box assembly and the pump cap assembly have gotten pretty dirty. I do clean periodically with Piezo Flush to keep them maintained.
Two questions when is it time or when can you know to replace these 2 items?
Secondly I started to get vertical banding in my prints. In the past I normally perform a head alignment once or twice and then I am good to go. Not so. I keep on getting the vertical banding returning after doing the alignment and then maybe printing one spread.
