NF3004-VA30A Tentative Printhead Under development High speed thermal printhead (300 dots / inch) NF3004-VA30A NF-VA30 series are the thermal printheads developed for high-speed / high-resolution printing for the market of bar-code printer & scale-printer, based on “step-free” structure. These printheads realize ultra-highspeed printing with long life & high reliability. zApplications Barcode printers Label printers Packaging printers ATM Ticket printers Scale printers zFeatures 1) High dot reproducibility with step-free structure. 2) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time. 3) Even without history-control, high-speed printing more than 300mm/s can be achieved at 300dpi with clear print image. With history-control, 500mm/s printing is also possible at 300dpi. zExternal dimensions (Unit : mm) DOT No.1 6±0.2 (26) Min. 4.3 (3.5) (7.792) Max. 48 Max.φ20 124±0.5 108.4 Max.5 #2 TYPE OF PRINTHEAD #1 #26 #6 #25 JST B6PS-VH HIROSE HIF3FC-26PA-2.54DS Max.10 #1 3-M3 EFFECTIVE DEPTH 3 100±0.2 2.8±0.2 7.3±0.3 17.8±0.2 (21.3) 25±0.5 (36) 10±0.2 14.208±0.2 φ3 H10 EFFECTIVE DEPTH 3 φ3 H10 LENGTH 4 EFFECTIVE DEPTH 3 40±0.3 (22) 80±0.3 DOT No.1 Note: No heat history control function inside the thermal printhead.
