Troubleshooting Canon MP Navigator EX with the PIXMA MP500

Tips & Tricks for Using Canon MP Navigator EX with the PIXMA MP500The Canon MP Navigator EX software is a useful complement to the PIXMA MP500 all-in-one printer, giving you control over scanning, image correction, and document management. Although the MP500 is an older model, with the right setup and a few practical techniques you can still get reliable, high-quality scans and streamline document workflows. This article covers installation and compatibility notes, practical scanning tips, image and OCR tricks, troubleshooting, and workflow suggestions to help you get the most from MP Navigator EX and the PIXMA MP500.

Check OS support first. Canon MP Navigator EX was designed for older Windows and macOS versions. On modern systems you may need compatibility mode or third-party drivers.
For Windows:
- If you have Windows 7/8/10 (32‑ or 64‑bit), look for the Canon MP Navigator EX installer specific to the MP500 from Canon’s support site or reputable archives. If an official installer for your exact OS isn’t available, install the closest supported version and run the installer in Compatibility Mode (right-click > Properties > Compatibility) set to Windows 7.
- Install the latest MP500 driver before MP Navigator EX. Printer drivers and software often work best when installed in driver → software order.
For macOS:
- Older MP Navigator EX releases supported macOS up to certain versions. On modern macOS, try native Image Capture for basic scanning, or use a compatible TWAIN/SANE driver (e.g., SANE backends, VueScan) if MP Navigator EX won’t run.
USB connection: Use a direct, quality USB cable and plug directly into the machine (avoid USB hubs) to prevent scan interruptions.

Use the correct scan mode:
- Document scanning: choose “Document” mode for multi-page text, set resolution to 300 dpi for OCR or 150–200 dpi for simple readable copies.
- Photo scanning: choose “Photo” mode with 300–600 dpi (or higher for archival needs).
Preview first. Always use the Preview function to crop and adjust the scan box—this saves time and yields cleaner scans.
Deskew and auto-crop: MP Navigator EX can detect and straighten slightly skewed originals—enable deskew for multi-page documents.
Color vs Grayscale vs B/W:
- Text documents: use Grayscale or Black & White for smaller file sizes and better OCR accuracy.
- Photos and color documents: use Color and a higher DPI.
File formats:
- PDFs for documents (multi-page PDF supported).
- TIFF for high-quality archival images (lossless).
- JPEG for everyday photos (smaller files).

Clean the scanner glass. Dust, smudges, or fingerprints cause artifacts; use a lint-free cloth and glass cleaner applied to the cloth (never directly on the glass).
Originals placement: Align the document against the top-left guide on the scanner bed for predictable cropping and consistent results.
Use the right resolution:
- 150–200 dpi — readable text, small files.
- 300 dpi — recommended for OCR and standard document archiving.
- 600 dpi — photo detail or text with small fonts (larger file sizes).
Color correction and auto-enhancement:
- Use MP Navigator EX’s “Auto Correction” for quick fixes.
- For photos, check color balance and saturation manually if the automatic result looks off.
Reduce moiré and pattern issues when scanning printed halftone photos by scanning at a higher resolution (600 dpi) and then downsampling.

Use MP Navigator EX’s built-in OCR for basic editable text conversion. For higher accuracy:
- Choose 300 dpi or higher when scanning text intended for OCR.
- Prefer Grayscale for text OCR (clean contrast helps recognition).
- Use plain, high-contrast originals (black text on white background).
Languages: Confirm the OCR language setting matches the document language.
Post-OCR proofreading: Always proofread OCR results—older engines can misread characters, especially with unusual fonts or degraded originals.

Creating searchable PDFs: Scan at 300 dpi and enable OCR (if available) to create searchable PDFs.
Combine scans into one PDF: Use MP Navigator EX’s multi-page PDF feature or scan separate pages and merge them into a single PDF within the software.
File size management:
- For long documents, use mixed settings: text pages at 300 dpi grayscale, occasional color pages as needed.
- Compress PDFs after creation if file size is a concern (many PDF utilities can reduce size while keeping acceptable readability).

Batch scanning: Use the auto-scan or multi-page options to scan stacks of single-sheet documents quickly (manually replace pages between scans).
Naming convention: Create a naming template (e.g., YYYYMMDD_Project_Page) to keep files organized and searchable.
Folder automation: Set MP Navigator EX to save scans directly into project folders or cloud-sync folders (Dropbox/OneDrive) to automate backups.
Integrate with editing tools: Send scans directly to image editors (Photoshop, GIMP) for advanced retouching instead of trying to perfect everything in MP Navigator EX.

Scanner not found:
- Confirm USB cable and port; try a different cable or port.
- Reinstall MP500 drivers first, then MP Navigator EX.
- On Windows, check Device Manager for driver errors; on macOS, check System Report > USB.
Crashes or hangs:
- Run the program in Compatibility Mode (Windows).
- Reinstall after removing all Canon software (use cleanup tools if available).
- Try alternative scanning software (Windows Fax and Scan, Image Capture on macOS, or third-party apps like VueScan).
Poor scan quality:
- Clean the glass, increase DPI, or enable image correction.
- Re-scan with adjusted contrast/brightness.
OCR failures:
- Increase dpi to 300+, use grayscale, ensure clear text, and correct skew.

If MP Navigator EX won’t run on your OS, consider:
- Native OS tools: Windows Fax and Scan, Windows Scan app, macOS Image Capture.
- Third-party apps: VueScan (broad driver support and advanced options), NAPS2 (open-source, strong OCR), or ExactScan (macOS).
For better OCR accuracy and features, consider dedicated OCR software such as ABBYY FineReader.
