Fix Slow Scanning in Adobe Acrobat 9 Pro with Canon MX925
Question details
The user is experiencing unusually slow scanning speeds when using Adobe Acrobat 9 Pro with a Canon PIXMA MX925, particularly during OCR-enabled PDF scanning.
- Product
- Adobe Acrobat 9 Pro, Canon PIXMA MX925
- Device & OS
- not provided
- Scenario
- Scanning documents to create OCR-enabled PDFs directly through Adobe Acrobat 9 Pro.
- Observed behavior
- The scanning process takes an unusually long time compared to scanning directly through the default Canon software.
Ensure your Canon PIXMA MX925 printer drivers are fully up to date and verify that scanning directly through the native Canon application operates at normal speeds.
Scan via Canon Software and Process in Acrobat Later
Bypass the Acrobat 9 compatibility issue by scanning directly with Canon's native software and importing the files into Acrobat for OCR later.
Adobe Acrobat 9 Pro is an older, unsupported version, making it prone to compatibility issues with newer scanner drivers and operating systems. This workaround avoids the slow communication between Acrobat and the scanner.
Launch the Canon IJ Scan Utility or the default scanning software provided with your Canon PIXMA MX925.
Scan your physical documents using the Canon software and save the output files in a high-quality format like TIFF to preserve resolution.
Open Adobe Acrobat 9 Pro, go to 'File' > 'Create PDF' > 'From File', and select your saved TIFF images.
Navigate to 'Document' > 'OCR Text Recognition' > 'Recognize Text Using OCR' to convert the imported images into searchable text.
Update Drivers and Check for OS Changes
Ensure your system's scanner drivers are compatible with your current OS setup, as outdated drivers can cause communication lag with older software.
Create and OCR PDFs Effortlessly with WPS Office
Instead of struggling with unsupported and slow legacy software like Adobe Acrobat 9, use WPS Office to create, edit, and apply OCR to your scanned documents quickly and accurately.
- 1. Open WPS PDF: Launch WPS Office and open the WPS PDF tool from the main dashboard.
- 2. Import Scanned Documents: Click on 'Open' to import your scanned TIFF or JPEG files, or use the built-in 'Picture to PDF' feature.
- 3. Run OCR: Navigate to the 'Tools' tab and click on 'OCR' to accurately extract and make the text searchable within seconds.
Frequently Asked Questions
Why is Adobe Acrobat 9 Pro scanning so slow compared to the Canon software?
Adobe Acrobat 9 is a discontinued product. Its legacy code often struggles to communicate efficiently with modern operating systems and newer scanner drivers, causing significant lag during direct scanning and OCR processing.
Can I fix the Acrobat 9 compatibility issue permanently?
Because Acrobat 9 no longer receives updates from Adobe, a permanent fix for hardware communication issues is unlikely. The best solution is to use the recommended two-step workaround or upgrade to modern PDF software.
Does scanning at a lower DPI speed up the Acrobat OCR process?
Lowering the DPI (e.g., to 150 or 200) can speed up the physical scanning process and reduce file size, but it may also decrease the accuracy of the OCR text recognition. It is generally recommended to scan at 300 DPI for optimal OCR results.
