How to improve poor scanning quality on Toshiba All in One Printer?
To improve the scanning quality on your Toshiba All in One Printer, regularly clean the document glass and the underside of the RADF. Ensure you are using a clean original document. Also, verify that the resolution setting in the scanner driver is appropriate for the original you are scanning.
What to do if Toshiba All in One Printer is unable to scan the image?
If your Toshiba All in One Printer is unable to scan images, try the following: If scanning is not possible, shut down your computer, turn off the machine's power switch, and unplug the machine's power cord. Next, start your computer, restore power to the machine, and try scanning again. Make sure your application is TWAIN/WIA compliant. Ensure that scanning preferences are set appropriately for the type of original to be scanned.
Why is the printed image dirty on my Toshiba All in One Printer?
A dirty printed image on your Toshiba All in One Printer may be caused by using paper outside of the specified size and weight range; use copy paper within the specified range. It could also be due to curled or damp paper. Replace any curled or crimped paper with dry copy paper.
How to fix skewed image on Toshiba All in One Printer?
If the printed image is skewed or runs off the paper on your Toshiba All in One Printer, check if the 'Paper Size' options match the size of paper loaded in the tray. Also, click the 'Paper' tab in the printer driver setup screen, and verify if the 'Image Orientation' option is set to your requirements. Ensure that paper is loaded properly. Verify that you have correctly specified the margins in the application you are using.
