Saved PDF corrupted

Welcome Jerry Huggins,

Thank you for posting. Since the PDF files are being created but appear corrupted when opened, I'd like to gather a little more information while also suggesting a couple of quick checks.  

Could you please let me know: 

• Approximately how large are the affected PDF files (for example, 0 KB, a few KB, or several MB)? 
• Are you able to open the same PDF on a different computer or mobile device? 
• Does the issue affect every scanned document or only certain scans? 

In the meantime, please try these quick tests: 

• Save a new scan to a local folder such as Documents instead of a network drive, USB drive, or cloud-synced folder 
• Open the PDF using Microsoft Edge by right-clicking the file and selecting Open with > Microsoft Edge 
• Check the file size by right-clicking the PDF, selecting Properties, and noting the Size. A file size of 0 KB may indicate the scan was not saved correctly 
• Create a new test scan using a different PDF filename and save location to see whether the issue occurs consistently. 

If the answer is helpful, please click "Yes". If you have extra questions about this answer, please click "Comment".

Problem resolved. Do not utilize the "HP Smart App" for the M234sdw Printer. This will result in a faulty scanned to saved .pdf output for both Wi-Fi and USB. Use instead the "HP App" which will provide a useable saved .pdf
