Core Upgrade Features
1. Smart Hardware Upgrade for Easier Operation
All models equipped with a 7-inch Android touchscreen system (Premium/Premium Ultra):
This feature was not available in previous versions. It allows real-time monitoring and direct control, streamlining the workflow. Technically supports handwriting file uploads and dual-band Wi-Fi (WiFi 5 / 2.4GHz) to prevent work interruptions caused by loose data cables.
Automatic Pen-Switching Function (Ultra only):An industry-first innovation that enables automatic switching between pens. Compatible with calligraphy pens, markers, and other tools with a diameter under 12mm. No manual intervention required—perfectly suited for complex design needs.
2. Massive Capacity & Smart Bulk Processing
Batch Writing Capacity per Load:
1. Premium: Paper tray height of 120mm, supports 1,200 letters + 350 envelopes per load.
2. Premium Ultra: Upgraded built-in power design with paper tray height increased to 240mm, supports 2,400 letters + 700 envelopes per load. Efficiency increased by 25 times, ideal for enterprise-level, large-scale requirements.
Note: The thickness and compactness of the paper directly affect the batch writing capacity. Actual performance is based on the paper tray height.
Printing Thickness and Paper Compatibility:
Premium/Ultra: Automatically adapts to paper thickness and supports all paper types available in the market (previous version had an upper limit of 250g/m²). Easily handles ultra-thick 350g/m² cards and envelopes.
Maximum Printing Thickness: Premium Ultra increases paper tray height to 240mm (compared to the previous version's 8–10mm), supporting the stacking of up to 700 ultra-thick sheets.
3. Blazing Fast Performance & Efficient Production
Premium Ultra Overclocked Speed:Now upgraded to 200 characters per minute (previous version: 145 characters) with 10,000-15,000 RPM high-speed rotation. This improvement boosts processing efficiency by 38%, making it perfect for enterprise-level large-volume tasks.
Industrial-Grade Power System:
Premium: Equipped with 6 industrial stepper motors (previously 2), providing doubled stability and precision, with closed-loop motors on the XY axis ensuring accurate high-speed writing.
Premium Ultra: 8 industrial-grade stepper motors designed for high-intensity, continuous operation with a 50% lifespan increase. The XY motors are extended closed-loop motors for precise high-speed writing.
4. Professional Compatibility & Precision Control
Closed-Loop Transmission Structure:
Uses closed-loop belts and HD linear slides, reducing maintenance costs by 40% and doubling the machine’s lifespan.
The paper lift platform features a 16mm ball screw, improving long-term durability.
High-precision laser-reflective sensors ensure consistent accuracy over long periods, unaffected by dust accumulation.
Smart Paper Detection:
Automatically recognizes SVG file size and text positioning (previous version required manual adjustments). Supports arbitrary sizes within A4 (including 4x6 index cards, #10 envelopes, etc.), achieving near-zero error rates.
5. Enterprise-Grade Expansion & Multi-Machine Coordination
Multi-Machine Control Seamlessly Upgraded: One computer can manage up to 200 iAuto devices (same as the previous version), but with the Premium Ultra’s 12-motor architecture, task distribution speed increases by 30%, and failure rates are reduced by 50%.
6. Enhanced Software Ecosystem for Limitless Creativity
Font Deformation 2.0:
A major upgrade from the previous "font deformation" feature, adding dynamic stroke algorithms and supporting one-click Quantum font imports (previously required manual adjustments). This enables the generation of thousands of handwriting variations.
SVG Streaming Processing:
A one-click multi-file upload system that automatically queues files for printing (previous version required individual file handling). Fully compatible with complex designs in Inkscape, resolving compatibility issues entirely.
7. Wireless IoT Connectivity with Industrial-Grade Stability
WiFi 2.4G/5G Dual Mode Connectivity:
Retaining the wireless functionality of previous versions but optimized for improved signal stability, reducing transmission latency by 70%.
64-bit Exclusive Motherboard & Industrial Power Supply:
Supports a wide voltage range of 110-220V, designed for 24/7 continuous operation, with a 60% improvement in heat dissipation efficiency.
