Operating Instructions
1. Loading Film and Slides
Use the appropriate film or slide holder for your media type. Ensure the film or slides are clean and free of dust before loading.
- For 35mm film strips, use the film holder. Carefully insert the film into the designated slots.
- For mounted 35mm slides, use the slide holder. Place each slide into its slot, ensuring correct orientation.
- Insert the loaded holder into the scanner's film slot.

Using SilverFast Ai Studio 9:
SilverFast offers extensive features for professional scanning and image optimization.
- Superb Scanning Resolution: The scanner provides a true 7200 dpi optical resolution, producing sharp and vivid images up to 68.9 megapixels.
- Advanced IT8 Calibration: Use the included 3-slide 35mm IT8 Calibration Target (ISO 12641-2 compliant 2019) for precise color calibration. This provides more measuring points for less interpolation, ensuring accurate color reproduction.
- iSRD (Infrared Smart Removal of Defects): This built-in infrared channel effectively removes dust and scratches from your scans. It works by performing a separate infrared scan to detect defects, then intelligently removes them from the final image without affecting important details. Note: iSRD does not work for B/W negatives as infrared rays cannot permeate the silver halide layer.
- Multi-Exposure: This feature increases the dynamic range of your scans, allowing for smoother gradations and fine shadow detail, especially in challenging lighting conditions.
- HDRi (High Dynamic Range Imaging): Captures RAW data from analog originals, including the infrared channel, into a 64-bit color HDRi file or a 32-bit grey scan HDRi file. This helps protect precious pictures against destruction and loss by preserving maximum image information.
- 16-bit Histogram: Provides a graphic representation of statistical visuals, allowing for precise adjustment of black point, white point, and midtones. Supports RGB and CMYK modes, combined or separated color channels, and color cast removal.
- NegaFix: Optimizes scans from negative film by providing profiles for various film types, ensuring accurate color and contrast conversion.
- Expert Mode: For advanced users, Expert Mode provides enhanced functionality and control tools for fine-tuning images, allowing for more detailed settings and protective layers.
- Built-in ICC Profile: The 8300i includes built-in ICC profiles for different slide films, including Kodachrome slides, ensuring consistent color representation from scan to print/display.

Using Plustek QuickScan Plus:
For quick and easy digitization, QuickScan Plus provides a simplified interface. Select your media type (positive or negative), desired resolution, and output format, then initiate the scan.
3. Saving Scans
Both SilverFast and QuickScan Plus allow you to save scanned files in various formats, including JPEG, TIFF, and RAW (HDRi for SilverFast). Choose the format suitable for your needs (e.g., TIFF for maximum quality, JPEG for smaller file sizes).
Maintenance
1. Cleaning the Scanner
Regular cleaning helps maintain scan quality and prolong the scanner's life.
- Exterior: Wipe the exterior with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Film/Slide Holders: Clean holders with a soft cloth or compressed air to remove dust and debris.
- Scanning Area: Use a can of compressed air to gently blow away dust from the film scanning area. Avoid touching the glass surface directly with your fingers. If necessary, use a lens cleaning cloth specifically designed for optical surfaces.
2. Dust Prevention
To minimize dust accumulation, store the scanner in its protective carrying case when not in use. Always handle film and slides by their edges to avoid fingerprints and dust transfer.
