Re: HP 525 MFP Fax Error Codes

The link you posted does not work for me.

Here is the resource that I use:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=uk&docname=buu02549#Error386

I am unfamilliar with error 82, it sounds like its too low to be a normal fax error message.  Checking the M525s support area I found this document:

http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/troubleshootDisplay/?sp4ts.oid=5118272&spf_p.tpst=psiContentDisplay&spf_p.prp_psiContentDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c03332227-12%257CdocLocale%253Den_US&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

From this page it would appear that anything other than a 17 or a 36 is a general communication error.  You should try disabling a feature known as ECM (Error Correction Mode).  ECM is known to cause many issues with modern day telephone lines.
