The Linx 8840 is engineered for demanding production lines where reliability, flexibility, and low total cost of ownership are critical. It supports printing up to six lines with variable character heights (from 1.8 mm to 20 mm), and runs at high speeds (up to 9.10 m/s in single-line mode) to match fast-moving lines.With an IP55-rated stainless steel enclosure, it resists dust and wash-downs for reliability in tough environments. The sealed printhead and AutoFlush system reduce cleaning frequency, while the Easi‑Change service module enables self-service maintenance at up to 18-month intervals. Fluid refilling is mess-free and error-proof, with 0.5 L ink and 1 L solvent cartridges changed while printing. The system includes a 7″ icon-driven touchscreen, complete with product image-based message selection, drag-and-drop layout editing, and multi-language support. Internal memory stores up to 1,000 messages, with USB backup and logs. Remote monitoring and control are available via Linx PrinterNet and Ethernet interfaces. It handles variable data like dates, times, batch numbers, sequential numbers, and provides vision-system-friendly fonts, rotated/tower printing, and graphic import capabilities—ideal for complex industrial coding.
