throw the *********** off niagra falls! Oh,one more chance to solve the problem? tell me! This copier was set up for 90 days to recieve faxes of which it may have recieved 10 test faxes then 2 or 3 real faxes then "ink system failure" 0xc18a0006. This cannot be difficult! As a technition for 40 years,a module swap would seem to resolve any problem. This is not right or fair. I have dozens of pc systems RFU. This one sat idle awaiting a lonesome fax and died without so much as breaking a sweat. No,a chicken did not **** in it! When my Moen faucet has problems,one call to Moen gets me a free overnight fix without a hassle. Why can't HP do as well? Doc Lowe, 512-422-6434; [email protected]; fax512-328-8793.........
