Around the second week in July we started having issues where our ImageClass MF247dw, MF267dw, and others would hang during a scan job to the connected computer, and eventually time out. I've followed all the recommended fixes I can find, and still several of the effected pc's have this problem on a daily basis, forcing me to uninstall and reinstall the printer/scanner again before they will function. Has anyone been tracking this, and has someone found a fix yet? Included are a couple of links explaining the problem.
