I have the latest Adobe reader
Adobe Reader cannot create a PDF (even from a scan).
Acrobat (Standard or Pro) is required for that.
Even with Acrobat the actual "scan" and image output is a process that is exclusive to the scanner and its software.
The scanner/scanner software image output file is handed off to Acrobat for conversion to PDF.
Not having Acrobat means that the PDF created is coming from software bundled with the scanner/scanner software.
That a version 1.3 (Acrobat 4) PDF is created indicates the bundled stuff is, well... "old" .
By design Acrobat creates/saves a PDF to a PDF version that is "one back".
Acrobat Pro has the ability to process a given PDF to be compatible with different PDF versions.
(e.g., the Optimizer facility or Preflights)
If it is important that you have a PDF created to a newer version you may want to consider obtaining Acrobat or updating whatever was bundled with your scanner.
Thanks so much!!
So my scanner inherently has software in it that creates the PDF in the old version. How can I update that? Is it possible? I have downloaded the latest drivers for my scanner and no luck.
The other solution is to purchase acrobat pro that will automatically create the scanned document in a newer version? How does my scanner know to use acrobat and not the scanner's PDF creator?
Drivers from the scanner vendor's site are not what is providing the output PDF.
Typically, a CD or DVD comes with a scanner. Look through those to see what was bundled.
There may be some information at the scanner vendor's website.
Should you install Acrobat then it can "talk" to a scanner provided the scanner uses TWAIN scanner drivers or Windows Image Acquisition (WIA) drivers.
You can use Acrobat to "create pdf from scanner".
Commercial scanner first - you'll want to speak with the vendor that provides service.
Individual scanners connected to local machines - Ayep; same vendor but different models or different vendors -- either would mean individual, piecemeal resolution.
If the devices are "office" equipment then someone-somewhere ought to have custody of the CDs / DVDs that came with the devices (...they are "business assets, no?).
Having the device's software CD/DVD will let you try to determine what may have been bundled that takes the scanner image file output and processes it to PDF (version 1.3). If you can identify what it is you can determine if that software is still available &, if available, does the vendor provide something current.
Or, look through the local machine(s) listing of installed applications.
