Canon Scanner LiDE 300 Flatbed Scanner

The CanoScan LiDE 300 is a flatbed document & photo scanner from Canon.  

1. It’s designed to scan documents, photos, receipts, magazines, etc. — anything that fits on the flatbed glass up to A4 / Letter size.  
2. It’s compact and lightweight, so it’s suitable for home, school, small office or personal use — especially if you have limited desk/ shelf space.  

Key Features

• High resolution scanning

1. Optical resolution up to 2400 × 2400 dpi — which allows for detailed scans of documents and photos, preserving sharpness and color fidelity.  
2. Using the included software, selectable resolution can go from 25 dpi up to 19,200 dpi (interpolated) for special use cases, though optical 2400 is the “true” hardware resolution.  

• Color depth and quality

1. Uses a CIS (Contact Image Sensor) with an RGB LED light source for scanning.  
2. Supports 48-bit input color depth (16-bit per color channel) internally, and can output at 48- or 24-bit on Windows; Mac output is 24-bit (8-bit per channel).  
3. For grayscale scans: 16-bit input, 8-bit output.  

• Speed & Convenience

1. Fast scanning: a full A4/Letter colour scan at 300 dpi takes ~10 seconds.  
2. Photo (4″×6″) at 300 dpi: ~5 seconds.  
3. 4 “EZ” buttons on the unit — quick one-touch scanning for common tasks (PDF, auto-scan, copy, send) without needing to open software menus.  

• Usability & Design

1. Powered via USB: both data and power come from a single USB connection — no external power adapter is required, which makes setup simpler.  
2. Supports maximum scan size: A4 / Letter (≈ 21.6 × 29.7 cm / 8.5″ × 11.7″) — good for standard documents, essays, photos, etc.  
3. Compact footprint (approx. 250 × 367 × 42 mm) and light weight (~1.7 kg) — handy for small desks or mobile setups.  

• Software & Extra Features

1. Includes scanning software (on Windows, macOS, and even with Linux support in some cases), allowing you to scan to PDF, JPEG, TIFF or PNG files.  
2. Features like auto image corrections (dust/scratch reduction, fading correction), auto scan mode (automatically detects document/photo and adjusts settings), and ability to send scans directly to the cloud (e.g. cloud storage) — helpful if you scan often and want ease.  

Limitations / What to Know

1. Because it uses a CIS sensor, depth-of-field is limited: scanning bulky or very thick items may not be ideal — only flat or near-flat materials will scan sharply.
2. Maximum scan size is A4 / Letter — larger documents or oversized photos won’t fit.
3. If you push the resolution setting extremely high (interpolated 19,200 dpi), “extra” detail is artificially generated — real detail is best at the 2400 dpi optical resolution.
4. It’s not a multi-page automatic-document-feeder (ADF) scanner; you have to place each page manually on the glass.
