Ricoh lists TH5241 as compatible with UV, solvent, aqueous and other ink systems. The printer's waveform, ink path and curing or drying system must match the ink being used.
Used in compatible sign graphics, label, textile, DTG and compact industrial UV printer systems where TH5241 is specified.
Confirm the head label shows TH5241, and send photos of the cable side and ink connection before ordering. Gen5i is not a substitute for Gen5 or Gen6 unless the printer maker specifies it.
Printheads are precision components. Use trained technicians, antistatic handling, correct cables, clean ink path, matched waveform, stable negative pressure and proper maintenance procedure. Do not touch the nozzle plate or electrical contacts.
Can I choose by the name Gen5, Gen6 or Gen5i only? No. Always confirm the exact Ricoh model code on the old printhead label, such as MH5420, MH5440, MH5320, MH5340, TH5241, MH2420 or GH2220.
Can one Ricoh printhead replace another Ricoh model? Not automatically. Cable, board, firmware, waveform, ink path, ink port and printer settings may differ.
