As I get my R2400 tomorrow I've studied posts which discuss it and other Epson printers. Conclusion, great printer but avoid letting it sit idle as heads clog. During longer periods between print jobs, would a print or two, scheduled weekly be effective to avoid print head clogging? Twice weekly? Biweekly? Perhaps printing a standard test print using all colors and containing large text date and leave it at the printer. Couple of 4x5 prints maybe? Is weekly adequate? Anyone using such a regimine? Effective? Keep it on always?
