DR-313 DR313 Color Developer Drum (A7U41TH) Original

The DR-313 Colour Developing Drum (A7U41TH) is a high-precision imaging component designed for OKI Pro series laser printers such as the Pro6410, Pro8432 and ES9540, capable of processing up to 300,000 pages in CMYK with multi-layer organic photoconductor (OPC) drum technology for professional continuous printing workflows in graphic design and mid-scale production departments. Its 4-station independent developing structure generates precise electrostatic transfer in cyan, magenta, yellow and black tones with uniform gradients and 5-25% coverage across the full spectrum, ideal for vibrant advertising materials, packaging mockups, creative graphics and executive presentations that demand perfect colour registration on papers up to 320 g/m². This drum ensures consistent printing in 30-100 daily user environments, maintaining impeccable colour alignment where every shade defines professional quality in complex visual compositions and medium-high impact communications.

The DR-313's engineering incorporates optimised photosensitive layers with 75,000 cycles per colour and a non-contact electrostatic cleaning system that removes toner residue without mechanical wear, supporting speeds of up to 45 ppm on A4 and 22 ppm on A3 with 1200 x 1200 dpi native resolution in ProQ mode. Its refined charge corona geometry prevents electrostatic build-up on coated, textured and synthetic papers with no density loss in continuous runs, while 175°C fusing technology supports automatic duplex modes and basic finishing such as hole punching or stapling. Perfect for reproducing rich colour gamuts in corporate brochures, multicolour backgrounds in catalogues, detailed marketing diagrams or point-of-sale displays, this colour developing drum handles intensive cycles without banding, ghosting or colour shifts on LED groupware printers.

In medium-volume professional business printing applications, the DR-313 A7U41TH Drum optimises operations in sectors such as creative agencies, brand design, editorial production and in-house marketing, where drum accuracy determines the colour consistency of medium run lengths, the perceived quality of promotional materials and the effectiveness of professional visual communications. Its integration with OKI Pro controllers enables centralised multicolour cycle tracking and predictive fleet management, preserving productivity in hybrid environments with mixed CMYK streams. Design teams select it for its sustained performance that transforms creative files into physical prints with vibrant colour and accurate registration, making it the essential component for continuous production visual communications and professional colour accuracy.
