Question details
Users encounter 'Error reading a stream' and 'Insufficient data for an image' when trying to open or return to previously opened PDF documents.
- Product
- Adobe Acrobat Pro 2015, Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Opening or revisiting scanned PDFs, especially those stored on a network file server, after the application has been running for a long time.
- Observed behavior
- Acrobat displays stream-reading and image-data errors, preventing the user from viewing or interacting with the PDF properly.
Save your current work and ensure you have administrative permissions on your computer to install updates or repair software components if necessary.
Test Locally and Update Acrobat
Isolating the file to a local drive helps determine if the issue is a network timeout or file corruption, followed by ensuring your software is up to date.
Network latency or brief connection drops to file servers can interrupt Acrobat's ability to read the PDF stream. Moving the file locally bypasses this issue.
Copy the affected PDF document from the network file server to your local hard drive (such as your Desktop).
Double-click the local copy to open it in Adobe Acrobat. Leave it open to see if the error persists.
If the error continues on the local file, go to the 'Help' menu in Acrobat and select 'Check for Updates' to install the latest patches.
Open your computer's Device Manager and ensure your printer and graphics card drivers are fully updated.
Restart Acrobat and Close Unused Documents
Because the error often occurs after extended use, restarting the application frees up system memory and resolves potential memory leaks.
Repair Installation or Recreate the PDF
If Adobe Acrobat components are corrupted or specific scanned files are damaged, repairing the software or rescanning the file can resolve the error permanently.

Frequently Asked Questions
What causes the 'Error reading a stream' message in PDFs?
This error typically occurs when the application loses its connection to a networked file, the PDF file is structurally corrupted, or the PDF viewer experiences a memory leak after running for an extended period.
How can I tell if my PDF is corrupted or if it's a network issue?
Copy the PDF from your network drive to your local computer, such as your Desktop. If the file opens and operates without errors locally, the problem is likely your network connection. If it still intermittently fails, the file itself may be corrupted or the software has a bug.
Can memory leaks cause PDF image data errors?
Yes. If a PDF application is left open for hours or overnight, it may fail to release system RAM. This resource exhaustion can lead to 'Insufficient data for an image' errors when you try to view or interact with open documents the next day.
