C360 randomly gives message to remove paper from glass when there isn't paper on the glass. Happens when customer attempts to feed paper thru doc feed. Paper is pulled thru just far enough to see it under the lid, then stops. The paper isn't jammed, the feeder just stops, then panel display the message to remove paper from glass. Not sure if this is related, but customer is now having to fax from the glass, single page at a time, but the fax is sent several times. Tx report indicates all are sent successful. Customer was previously using 4 wire, suggested 2 wire, but that didn't fix the problem. Considering bad fax card?? Any suggestions? (PS- don't hold it against me, but I'm not a tech.
I'm the sales rep, but I think it is extremely important, for myself anyway, to know the tech side of things.) Appreciate any troubleshooting ideas!
