I have a relatively old Office Jet 5610 All in One printer/fax. The problem I have is that once it a week it automatially dials the following fax number - 13452105. It also dials this number if we have a power cut or if I switch off the mains. These call charges are appearing on my phone bill. My question is this - how do I stop the Office jet from auto dialling this number. I have no idea of who the number belongs to. If I dial the number I just get a fax squelch sound. Any help/advice would be much appreciated.
