Konica KM1024i 6988H Printhead

The Konica 6988H Printhead, also known as the Konica Minolta KM1024i 6988H, is a high-speed, piezo drop-on-demand inkjet printhead with 1024 nozzles arranged in 4 lines of 256 nozzles each, enabling high precision and positioning accuracy for high-definition print quality.

Printer & Application Match

•     Your printer is designed for KM1024i MHE 13pl heads or explicitly lists 6988H as compatible (e.g. Agfa Anapurna series, some single-pass UV/solvent lines).
•     Target application: high-speed single-pass industrial printing (textiles, signage, décor) where 45 kHz drive frequency is required.
•     Print resolution requirement: up to 360 npi (90 npi × 4 lines) with 8-level grayscale.

Ink Compatibility

•     Ink type matches head: UV, solvent, or oil-based inks are supported; water-based is not for the 13pl variant.
•     Ink viscosity: 6988H is the 13pl MHE variant, optimized for medium-high viscosity inks compared to 6pl/30pl variants.
•     Confirm ink supplier explicitly states compatibility with KM1024i 13pl / 6988H.

Electrical & Control Interface

•     Your driver board/electronics are for KM1024i MHE (electric board is shared between 6988H and KM1024iMHE-D).
•     Firmware / driver supports independent drive system and up to 45 kHz firing frequency.
•     Connector type, cable length, and signal timing match the Konica KM1024i series standard.

Mechanical Integration

•     Head carriage and mounting allow the KM1024i dimensions: 131 × 18 × 94 mm and ~150 g weight.
•     Print width requirement ≤ 72 mm per head (or designed for multi-head arrays).
•     Adequate ink circulation path and pressure control (head supports circulation, important for precipitating inks).

Thermal Management

•     System can use the built-in heater and control head temperature for your ink viscosity range.
•     Cooling / enclosure design prevents overheating during continuous high-frequency operation.

Availability, Price & Support

•     We provides authentic Konica Minolta heads with traceable batch/serial numbers.
•     We hava clear warranty term (e.g. 6–12 months) and return policy for defective units.
•     Local or regional support available for installation, alignment, and troubleshooting for some country/region.
•     We have price that includes necessary accessories (cables, connectors, O-rings, mounting hardware) or you have them separately.

Mixing & Replacement Rules

•     You will not mix 6988H with other KM1024i variants (e.g. 6pl/30pl) in the same printer unless the machine is explicitly designed for mixed heads.
•     If replacing a single head in an existing machine, confirm that only one head type is used in that carriage position.
• If most boxes are checked and your ink/printer/electronics are explicitly compatible, the KM1024i 6988H is a solid choice for high-speed, high-definition industrial printing.

Quick Comparison: KM1024i 6988H vs Other KM1024i Variants.

The 6988H is essentially the KM1024iMHE-D 13pl head under a different model name for Asia/China markets.

Key practical point:

6988H = KM1024iMHE-D 13pl in function; you can treat them as interchangeable if your machine is designed for the MHE 13pl head, but do not mix different drop sizes in the same printer unless the design explicitly allows it.
