Hi shaw6363,
You can download the latest drivers from the Canon USA website to reinstall the printer. Please click here to go to the Drivers and Downloads page for the PIXMA MX512 (uses the PIXMA MX510 series drivers and software). Once on the page, please do the following:
1. Verify that the operating system detected in the "OPERATING SYSTEM" field is correct, and if it is not, please click the drop-down menu to select your operating system. Please note that you may need to scroll up or down in the list to select your operating system.
2. Next, below the red box labeled "RECOMMENDED DOWNLOADS", locate the CUPS file, then click the SELECT button to the right of the filename. When you do, a dark gray DOWNLOAD button will appear; below that, a checkbox will be shown asking you to agree to the terms of the disclaimer to continue with the download. Please click in that checkbox to agree to the terms. When you do, the dark gray DOWNLOAD button will turn red. Please click on the now red DOWNLOAD button; the file will start downloading. The time for the download process may vary depending on the speed of your Internet connection and the size of the file being downloaded.
Once you have downloaded the CUPS driver file from the website, please also download all other items from the RECOMMENDED DOWNLOADS, DRIVERS and SOFTWARE sections of the webpage. Please be sure to download and the Canon IJ Network Tool from the SOFTWARE section if you are using the printer wirelessly. If you have the printer connected via USB cable, you do not need to download the Canon IJ Network Tool.
Once all items have been downloaded, please double-click on each of the items on your Mac to install them, starting with the CUPS drivers file. Please ensure that the Canon IJ Network Tool is the very last item installed if using the printer wirelessly.
Hope this helps! Should you need further assistance, please call 1-866-261-9362, Monday - Friday 10:00 a.m. - 10:00 p.m. ET (excluding holidays) and a Canon technical support representative will be happy to help. There is no charge for this call.
