Error 380: Invalid property value

There are a number of different situations in which this error may be encountered.


Error 380 may indicate that there is a problem with MS Sans Serif and Small Fonts. The error may occur after the display of a message such as the following at program start-up:

Following basic windows screen fonts are not found
MS Sans Serif
Small Fonts.


  1. Go to
  2. Click on and download these two files: sserife.fon.ocx and smalle.fon.ocx.
  3. Rename the files to sserife.fon and smalle.fon respectively.
  4. Right click on each file and select Install for all users.
  5. Reboot the computer.

Windows XP Solution

In Windows XP, this problem can usually be solved as follows:

  1. Open the Control Panel.
  2. Open the Fonts folder.
  3. Under the Tools menu, select “Folder Options.”
  4. Click on the “True Type Fonts” tab.
  5. Clear the checkbox (“Show only TrueType fonts…”).
  6. Click OK.
  7. Reboot computer.

Because these fonts come with Windows it is usually not necessary to install them. However, if it is necessary, one source is the Fonts folder on any CFS multi-program CD. Another source is any other Windows computer. The fonts can be copied from the computer’s Fonts folder to a flash drive, then copied from the flash drive to the computer that needs them. The file names for these fonts are SSERIFE.FON and SMALLE.FON.


Arial.TTF is another standard Windows font, the absence of which may cause error 380 when attempting to fill in a form. Check the Fonts folder in the Control Panel and make sure the Arial.TTF font is present. Should you need to install it, this font may also be found in the CFS CD Fonts folder or on another Windows computer.

Hidden Fonts

A font may be present in the Font folder but not visible because the “Hidden” attribute is set. While in the Font Folder, tap the Alt key to show the menu bar. From the Tools menu, select “Folder Options…,” Click the “View” tab, and make sure “Show hidden files and folders” is selected. If you find a font with the “Hidden” attribute set, clear the “Hidden” check box under file properties.

Incorrect Printer

Error 380 may also be caused by the accidental selection of an incorrect printer: for example, when attempting to print labels with a photo printer. Usually, if the user selects “Print” from the File menu and selects a printer other than the default printer, there will be no problem. However, if error 380 is encountered, try setting the Windows default printer to be the desired printer, restarting the program, and trying again.

Adobe PDF Writer Resolution

Error 380 may also be caused by printing to Adobe PDF Writer with the resolution set at “screen resolution” instead of a numeric value, such as 150 or 300 DPI.
