I hope I am posting in the right section... I have a Canon Pixma mp830 Office All-In-One, and I am having trouble faxing. We've went through the troubleshooting, unplugged the machine (and plugged it back in,) restarted the machine, and made sure the phone cable is plugged in the right spot. but we keep getting error reports. The fax never follows through. Has anyone run into this before with Pixma machines and have found a solution? Or does anyone know printers enough to still throw more options at us?? Any help would be greatly appreciated.

Have you had any experience with faxing before? Canon has pretty good support. If you search their web site using the exact wording of the error message, or at least a few words in a row in that message, you are likely to find useful troubleshhoting information. If you are using a DSL or ADSL high speed internet connection, if the telephone port on the Pixma is connected to the same telephone line as you use for your DSL or ADSL, you MUST use a DSL or ADSL blocking filter inline between the phone line source and the Pixma port, otherwise the dial-up modem inside the Pixma cannot work properly for faxing. If the Pixma has two phone line ports, make sure the phone line source is connected to the LINE port, not the Phone port - some dial-up modems will not connect properly otherwise. In some areas these days, you must use an area code with all phone numbers even if they are local - if you are supposed to use the area code with local calls, you must use the area code with the fax software. A USB connected device may not work properly unless you plug it into a USB port it is more likely to work properly in, or you may have an IRQ sharing problem.

@Tubesandwires: "Have you had any experience with faxing before?" Of course! I am sure Canon support is good, but when your warranty runs out, you have to pay for it. At least phone support. I wanted to post here before I started an email ticket because I generally get faster responses through forums. I don't see how it could be a USB issue when everything else works fine (printing, scanning.) Anybody else have any suggestions? Thanks in advance.

It's likely there is nothing wrong with the Pixma that would require a physical repair. I have a 1999 Canon printer that works fine, and I have had older Canon printers as old as the early 90s that worked fine. I suggested looking on the Canon web site to see if you can find a solution related to your error message(s). If that doesn't help, you need to state the exact error message(s) you are getting, and when you are doing what. The dial-up modem, which is what your fax software uses in the Pixma, will probably not work properly if it is sharing the IRQ it uses with anything else. If you have a desktop computer, take a look in System Information (Start - Run - type: msinfo32 , click OK) on the left side under Hardware Resources - IRQs. If the dial-up modem is using the same IRQ as another device in a card slot, try moving the card to another slot. If you try that, unplug the case, or switch off the AC power to it while doing that. Do not use the PCI slot on the end closest to the middle of the mboard for anything but a PCI video card - that slot is forced to share it's IRQ with the video and that usually causes problems.
