Summary: Like the reviewer previous, I use one of my Ricoh printers for specialty inks. Unlike the Epson printers I have had in the past, I have had absolutely no issues with print head clogging. The gel inks are awesome. I purchased this Ricoh to do my "regular" printing and have never had one issue although I have had to leave it unattended for several weeks at a time. I bought this same unit for home.
