Canon PIXMA MG6821 User Manual - Page 787

• Images may not be scanned correctly in some applications. In that case, increase the operating system's virtual memory and retry. • When image size is too large (such as when scanning large images at high resolution), your computer may not respond or the progress bar may remain at 0 % depending on the application. In that case, cancel the action (for example by clicking Cancel on the progress bar), then increase the operating system's virtual memory or reduce the image size/resolution and retry. Alternatively, scan the image via IJ Scan Utility first, then save and import it into the application. 787
