How to Fix Adobe Acrobat Scanner Page Dimension Errors
Question details
The user encounters an error in Adobe Acrobat stating that valid page dimensions are required when attempting to scan a document.

- Product
- Adobe Acrobat 2017
- Device & OS
- not provided
- Scenario
- Scanning a physical document into a PDF file using an HP OfficeJet Pro 8610 or similar scanner directly through Adobe Acrobat.
- Observed behavior
- Acrobat blocks the scanning process and displays an error message stating that "valid page dimensions are required," preventing the creation of the PDF.
Ensure your scanner is turned on, securely connected to your computer, and functioning properly outside of Adobe Acrobat. Having your specific printer or scanner model number ready will help you locate the correct drivers.
Update Drivers and Configure Settings via Manufacturer Software
Resolving the dimension error usually requires updating the core scanner drivers and bypassing Acrobat's built-in scan configurations in favor of the manufacturer's native software.
Often, communication errors between Adobe Acrobat and the scanner driver prevent the correct paper size from being detected. Updating the HP utilities and defining the parameters in the native driver application resolves this conflict.
Navigate to the official HP support website, search for your scanner model (e.g., HP OfficeJet Pro 8610), and download the HP Print and Scan Doctor utility.
Install and launch the HP Print and Scan Doctor. Follow the on-screen prompts to automatically detect and repair missing or corrupted scanner components.
From the same HP support page, download the latest driver software and firmware updates for your operating system. Install them and restart your computer.
Open the native HP printer driver application on your computer instead of Adobe Acrobat. Manually configure your scan parameters, ensuring standard options are selected for page size, source, and resolution.
Reopen Adobe Acrobat and attempt the scan again. Ensure the standard page dimensions you configured in the HP software are being recognized.

Scan Documents to PDF Easily with WPS Office
If Adobe Acrobat continues to show dimension errors or driver conflicts, you can bypass the issue entirely by using WPS Office. WPS provides a straightforward, highly compatible built-in tool to scan your physical documents directly into high-quality PDFs.
- 1. Open WPS PDF: Launch WPS Office on your computer and click on the 'PDF' tab on the main home screen.

- 4. Adjust Settings and Scan: Adjust your desired scan settings such as page size and color mode, then click 'Scan' to create your PDF document instantly.

Frequently Asked Questions
Why does Adobe Acrobat say 'valid page dimensions are required'?
This error typically occurs when the communication between Adobe Acrobat and your scanner's driver fails to transmit the correct physical paper size, often due to outdated drivers, corrupted firmware, or software update conflicts.
Can I fix this error without downloading new drivers?
Sometimes you can work around the error by changing Acrobat's scanning method. In Acrobat's Custom Scan menu, uncheck 'Hide Scanner's Native Interface'. This forces Acrobat to open your scanner's native software prompt, where you can manually define the correct page size before scanning.
Where can I find the HP Print and Scan Doctor tool?
You can download the HP Print and Scan Doctor directly from the official HP Customer Support website. Go to the 'Software and Drivers' section and enter your specific printer or scanner model number to locate the correct utility download.
