4.5.5 INTERPRETING FEATURE REPORT

Error Handling

When receiving a feature report, the local IFAX interprets the seven entries of the
Media Accept Features field (☛4.5.4). The local IFAX, if having detected an error
in an entry, registers the error code. The data in this entry is ignored. Some
examples of errors are as follows:
• A syntax error is detected.
• An unknown parameter (including typographic errors) is detected.
• Image Coding, Resolution, and Paper Size are not defined.
• The entries inconsistent with the default (☛ 4.5.2) are regarded as errors.

Exception Handling

If one or two of Image Coding, Resolution, and Paper Size are not defined (if only
one or two of them are defined), the local IFAX registers the defined parameters.
Undefined parameters are set to the default (☛ 4.5.2).
If multiple combinations are defined for Image Coding, Resolution, and Paper Size
(for example, "200/400 dpi for A4" and "200 dpi for A3"), the local IFAX interprets
them in the following order:
1) Paper Size: The local machine regards all paper sizes as supported.
2) Resolution: The local machine regards the common parameters as
supported. In the case of the above example ("200/400 dpi for A4" and "200
dpi for A3"), "200 dpi" is regarded as supported.
3) Image Coding: The local machine regards the common parameters as
supported.
