Confirm whether your printer needs MH5320, MH5340 or MH5320 Type A. Send the old head label, cable type, current ink, printer model and nozzle test before purchase.
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.
