<div class="content" name="FAX_GetPageData" uuid="745b56b0-feb8-4bc5-915c-7541c3e77d7e"><p>The <b>FAX_GetPageData (Opnum 7)</b> method is called by the
client to retrieve data in the first page of an outgoing fax job. The
information that is returned in the buffer is an in-memory copy of the first
page of the <a href="46aba9c4-ebb1-4b10-86ac-4bb3025657b9#gt_eddadea9-c278-4d16-9279-f222df2cb735" data-linktype="relative-path">TIFF</a> file.
The value for the <i>JobId</i> parameter can be obtained using one of the
following methods: <b>FAX_EnumJobs</b> (section <a href="6516d564-e0b8-4f19-80b1-70f27eca7f16" data-linktype="relative-path">3.1.4.1.21</a>), <b>FAX_EnumJobsEx</b> (section

<a href="cec559b7-44b6-47a9-b402-7dc5af788f44" data-linktype="relative-path">3.1.4.1.23</a>).</p><p>In response, the server MUST validate that the <i>JobId</i>
is for a valid job. The server MUST validate that the client&#39;s fax user account
has read access to the job. On success, the server MUST return the first page
of data for the <a href="46aba9c4-ebb1-4b10-86ac-4bb3025657b9#gt_c1a6400d-703b-4f9a-a74c-40f1487978d9" data-linktype="relative-path">queued</a>
