Adobe will disable support for authoring with Type 1 fonts in January 2023. See the Postscript Type 1 End of Support help article for more details.
When you open a document in Adobe InDesign CS, Adobe InDesign CS returns the message "Missing Fonts. The document [file name] uses one or more fonts which are currently not available on your system. The text will use a substitute font until the original font becomes available."
The document was created in InDesign 2.x.
The Info section of the Find Font dialog box shows "0" for Character Count or "None" for Pages, indicating that the font isn't used in the document. (Choose Type > Find Font, select the font, and click More Info.)
You have two versions of the same font installed (for example, a TrueType and an OpenType fonts from Adobe version of Times New Roman).
Do one or more of the following solutions:
Solution 1: Upgrade to InDesign CS2.
You can purchase upgrades from Adobe Authorized Resellers and from Adobe directly:
-- To locate an Authorized Reseller, visit the Adobe website at http://partners.adobe.com/resellerfinder/na/findreseller.jsp or call Customer Services at 800-833-6687.
-- To purchase an upgrade from Adobe, visit the Adobe Store at http://store.adobe.com/store/products/master.jhtml?id=catInDesign, or call Customer Services at 800-833-6687.
Solution 2: Export the document to InDesign Interchange (.inx)format, and then check the font information.
1. In InDesign CS, choose File > Export, and choose InDesign Interchange from the Save As Type menu.
2. Click Save.
3. Open the .inx file in InDesign CS.
4. Choose Type > Find Font, select the font, click Find First, and check More Info.
Solution 3: Determine if the font was applied to a space character or a text box, and then replace the font.
1. Open a copy of the document.
2. Choose Type > Find, select the font, and click Find First.
3. If the font is applied to a space character or text box, replace it with a different font, and then click Change.
InDesign returns a message that fonts are missing if a font is applied to a space character, if a font is applied to a text frame, or if two versions of an installed font have the same name. CoolType groups font families according to technology, so an OpenType font from Adobe and a TrueType font with the same name are grouped together as one family. It's uncommon for OpenType fonts from Adobe and TrueType fonts to have the same name. For example, OpenType fonts from Adobe have a .pro or .std suffix to distinguish them from other fonts. OpenType fonts from Adobe that have TrueType outlines essentially use the same technology as TrueType fonts.
This issue doesn't occur in InDesign CS2.
Exporting to InDesign Interchange format removes features that aren't in InDesign 2.x, but doing so can salvage corrupt data.
