Epson DX5 / DX7 Eco-Solvent Printhead Guide

Resource Center › Knowledge Center

The Epson DX5 and DX7 are the dominant eco-solvent printheads used in Roland, Mimaki, and Mutoh wide-format printers — both have 1,440 nozzles (180 × 8 rows) and 1,440 dpi resolution, but they are not interchangeable due to different printer board interfaces. The DX5 (9–12 month lifespan) is used in older Roland VS and BN series, Mimaki JV33 and JV150, and Mutoh ValueJet 1204. The DX7 (10–14 month lifespan) has improved solvent resistance and a smaller minimum drop size (1.5 pl), and is used in Roland VG series, Roland RA-640, Mimaki JV300 and CJV150 later models, and Mutoh ValueJet 1638X. Always confirm your specific model number and serial number before ordering — Roland and Mimaki made running production changes within series that affect head compatibility. Genuine OEM DX5 and DX7 printheads ship same day from Doral, FL before 2PM EST.
