Ricoh officially lists GH2220 compatible ink as aqueous and solvent. If a UV Imprimante claims GH2220 compatibility, confirm the exact Imprimante configuration and ink supplier avant commande.
Used in compatible sign graphics, textile, coding, marking and compact Imprimante systems where GH2220 is specified.
Send the old head label and Imprimante Modèle avant commande. Do not assume GH2220 can replace a Ricoh MH-Série Tête d'impression.
Têtes d'impression 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 Modèle code on the old Tête d'impression label, such as MH5420, MH5440, MH5320, MH5340, TH5241, MH2420 or GH2220.
Can one Ricoh Tête d'impression replace another Ricoh Modèle? Not automatically. Cable, board, firmware, waveform, ink path, ink port and Imprimante settings may differ.
