 What is PDF?
PDF (portable document format) is a universal file format that anyone, anywhere can open with free Adobe® Acrobat® Reader™ software. PDF files display exactly as created, regardless of fonts, software, and operating systems. You must have the full version of Adobe Acrobat software to create PDFs.
 
 How Can I Get Adobe Acrobat Reader?

To view PDF files, you must have Adobe Acrobat Reader or the full version of Adobe Acrobat software installed on your machine. Click here to download the free Adobe Acrobat Reader, then follow the instructions on Adobe's Web site. Adobe Acrobat Reader is available for a variety of platforms and languages.

 
 Need Help?
Solutions for common problems reported to DEQ's Webmaster are outlined below. If you need further assistance, look in Adobe Reader's "Help" section on the menu bar at the top of the Adobe Reader screen. Still need help? Contact DEQ's Webmaster.
 

 Problem 1: The PDF file won't open, or the file opens, then "freezes."

NOTE: If you get a message that says "URL not found" when you click on the PDF document, the problem is not with the PDF, but with the link. Contact DEQ's Webmaster.


Solutions: (You likely will not need to do all of these. Try them in order and try to open the document after each one.)

   
A. Be sure you have Adobe Acrobat Reader installed on your machine. If you don't (or aren't sure), click here to download the free Adobe Acrobat Reader.
   
B. If you already have Reader, be sure you have the most recent version installed on your machine. If you don't (or aren't sure), click here to download. The Adobe Reader on your desktop or in your list of programs will tell you what version you have (e.g., Adobe Reader 7.0). Make sure you uninstall all previous versions of the Reader before installing the new. (If you have the full Adobe Acrobat software package, be sure to open documents using this software rather than Reader only.)
   
C. Check the file size. The file size is listed for PDF documents on DEQ's Web site. Files larger than 1.5 mb may be difficult to open over a telephone modem. Large documents have been divided into pieces for easier downloading. If the document is still too large for your modem, contact DEQ's Webmaster. Also verify your connection speed setting in Adobe Acrobat. Open the Edit dropdown menu and click on Preferences to view your Internet Connection Speed. If your Internet connection is by telephone, the connection speed should be set between 28 and 56K, depending on the speed of your model. If your Internet connect is by cable or ISBN, the connection speed should be set on 256K.
   
D. Change the default settings in Adobe Acrobat Reader.
 
  • Open Adobe Acrobat
  • Go to Edit/Preferences/Internet
  • Turn off (uncheck) 'Allow speculative downloading in the background'
  • If problem persists, go back to Edit/Preferences/Internet and turn off 'Allow fast web view' as well
   
E. Force PDF documents to open in an Acrobat window instead of in a browser window.
 
  • Open Adobe Acrobat
  • Go to Edit/Preferences/Internet
  • Turn off (uncheck) 'Display PDF in Browser'
   
Note: You only need to change the default settings in Solutions D and E once. These changes will apply to all PDF documents you open from the Web until you change them back.
 
F. Save the document to your computer, then open from there.
 
  • Right click on the link to the PDF document
  • Choose "Save Target As"
  • Navigate to where you want to place the document on your computer
  • Open from your computer
   
Note: Solutions E and F can cause a different problem (see Problem 2, Solution C) if the document has external links. Only apply solutions E and F if necessary. If you must apply Solutions E or F to solve Problem 1, and the document also has external links that won't work, contact DEQ's Webmaster.
 

 Problem 2: Links in the PDF file don't work.

Solutions: PDF files have many types of links. If none of the links work and you cannot navigate at all (the document is frozen), try steps B through E for Problem 1, above.

If the document is not 'frozen,' determine what types of links don't work.

 
A.

Bookmarks. The most common links are bookmarks (found to the left of the PDF document when viewed on your screen). These help you navigate within the document. They are similar to an electronic table of contents. (Occasionally, bookmarks may also be set up to link you to a different document [an external link]).

If one or more bookmarks do not work (you click and nothing happens), but you can navigate manually by scrolling or clicking on arrows, the problem is likely in the book marking. Contact DEQ's Webmaster.

If most bookmarks work, but a few don't and you get an error message, the bookmarks are likely serving as external links. See 'external links' below.'

   
  If you already have Reader, be sure you have the most recent version installed on your machine. If you don't (or aren't sure), click here to download. The Adobe Reader on your desktop or in your list of programs will tell you what version you have (e.g., Adobe Reader 7.0).
   
B.

Internal Links. A document may contain links that help the reader navigate within the document. These usually appear as hyperlinked text and when you click on a link you jump to elsewhere in the same document.

If one or more internal links do not work (you click and nothing happens), but you can navigate manually by scrolling or clicking on arrows, the problem is likely in the links. Contact DEQ's Webmaster.

If you get an error message when clicking on a link, it is likely an external link. See below.

 
C.

External Links. A document may contain links to other PDF documents, to documents in other formats (e.g., Word), or to other Web pages. These usually appear as hyperlinked text, but when you click you jump to a different document or Web page.

If one or more external links do not work (you click and nothing happens [no error message]), but you can navigate manually by scrolling or clicking on arrows, the problem is likely in the linking. Contact DEQ's Webmaster.

If one or more external links don't work and you get an error message, the link is not finding the document or Web page is it searching for. You will likely get one of two error messages.

  • URL Not Found. The URL the link linked to likely changed. Contact DEQ's Webmaster.
  • Specified File XXXX Does Not Exist. The program is looking in the wrong place for the file or the file has been deleted. You will need to open your document in the browser for the link to work.

If you saved the document to your hard drive, simply go back to the original Web link and re-open in the browser by clicking on the link.


If you have your preferences set to open in the Acrobat window instead of the browser window (see Solution E, Problem 1 above), follow the steps listed in Solution E, but turn on 'Display in Browser.' This will apply to all PDF documents you open from the Web until you change it back. Go back to the original Web link and re-open the document from the Web.

If the links still do not work, there may be a problem with the links. Contact DEQ's Webmaster.

   
  Note: Solutions E and F can cause a different problem (see Problem 2, Solution C) if the document has external links. Only apply solutions E and F if necessary. If you must apply Solutions E or F to solve Problem 1, and the document also has external links that won't work, contact DEQ's Webmaster.
