Konica 3688H Printhead

The Konica 3688H printhead, also known as the Konica Minolta KM1024 3688H or REVO-E, is a robust, shear mode, piezo on-demand inkjet printhead. It supports both binary and 8-level greyscale printing modes and has 1024 nozzles with a droplet size of about 6 picoliters. The native resolution is around 360 dpi, making it suitable for high-quality UV and other inkjet printing applications. It is a widely used printhead in large format and industrial printers.

Compatibility & application

•     Your printer model is explicitly listed as compatible with KM1024 3688H (e.g., AOjet APro 320F, Docan, Inktec models).
•     Your inks are UV or solvent and rated for Konica piezo heads (not extremely high viscosity or abrasive).
•     You need high-speed, wide-area printing (signage, floors, PVC, glass, wood) rather than ultra-fine photo detail.

Technical specs fit your needs

•     Nozzles: 1024 (twice the KM512 family).
•     Droplet size: 6 pL, good balance of speed and quality for most industrial uses.
•     Native resolution: 360 dpi; physical resolution around 720 dpi with driving electronics.
•     Grayscale: Up to 8-level gray mode in addition to binary mode.
•     Heater: Integrated heater is present (verify firmware/driver supports it).

Condition & authenticity

•     This printhead is original / new / genuine Konica Minolta and provides a serial or batch code.
•     On product listing or invoice clearly specifies model: KM1024 3688H / REVO-E (not just “Konica 3688H” generically).
•     No signs of prior use: no dried ink, no damaged nozzles, no worn signal tape connectors in photos or upon receipt.
