    <description>&lt;P&gt;Hello Duckman,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The filter failed message will appear when a Mac has a problem processing a print job. If you are having the issue with only one specific document, it might mean that the data for the document is corrupted for that PDF.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;You can try resetting the printing system on your Mac and then adding the printer back to your Mac to see if you can now print that PDF.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;OL&gt;&lt;LI&gt;Click on the apple in the upper left hand corner of the screen and then click on system preferences. Once in system preferences click on Printers and Scanners.&lt;/LI&gt;&lt;LI&gt;In printers and scanners, right click on a blank portion of the printer list and then select "reset printing system".&lt;/LI&gt;&lt;LI&gt;Click the + at the bottom of the list.&lt;/LI&gt;&lt;LI&gt;Select the MF642 and then click add.&lt;/LI&gt;&lt;/OL&gt;&lt;P&gt;If you continue to have the issue, you can try downloading and installing the printer driver for the MF642 using the link below.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;A href="https://www.usa.canon.com/internet/portal/us/home/support/details/printers/color-laser/canon-color-imageclass-mf642cdw" target="_blank"&gt;https://www.usa.canon.com/internet/portal/us/home/support/details/printers/color-laser/canon-color-imageclass-mf642cdw&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Once the driver has been reinstalled, you can try resetting the printing system one more time and adding the printer back to the list.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Did this answer your question?

      <title>imageCLASS MF642Cdw 'Filter' failed error message</title>

      <description>&lt;P&gt;"Filter failed" message is generated by one PDF, but others print perfectly on my Imageclass MF642CDW. &amp;nbsp;My Imac runs High Sierra 10.13.6 and the PDFs that generate the error were downloaded from Vanguard, but are similar to others downloaded from other sites. &amp;nbsp;Any ideas? &amp;nbsp;How can one PDF be different from another?&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks for the reply. &amp;nbsp;I found a work around by opening the document in question with Adobe Reader instead of the default (Preview). &amp;nbsp;It printed just fine that way, for reasons I still don't understand.&lt;/P&gt;</description>
