I'm not sure what kind of environement you've had the printers in, nor what changes in operating systems or upgrades they might have been subjected to. You can do one thing for your system of computers running these. Download Ccleaner free and clean up your computers. Then hold down the Windows logo key and press the R key. When a new window opens type in %temp%. Delete every possible filw from that hidden temp file window that Windows will allow.

Reboot

Uninstall both printers from the control panel and DO NOT allow them to retain any settings

run Ccleaner again

clean temp again
reboot

The go to the respective Support sites for these computers, download the drivers/software and install WITHOUT the computers being connected until prompted.

Get help with this.

Hello, I do not know what OS you have on your PC, so I am going to give you two links to click on. They will take you to both Model's Support Webpages. From there you need to click on the DOWNLOADS button and Choose Your OS. Irecommend that you install ALL of the Most Current Updates for each Printer. Hopefully that will solve your issues. OK?

Power is on to my Canon Pixma MP780, but no display


I got such problem on my MP 780 (grayed boxes on bottom LCD line, no function). It turned out to be missing 1.5V for CPU core. On revese (solder) side of mainboard i found point described as "1.5V". I've powered this from external supply (took about 2 amperes) for few seconds and MP is alive again (without external supply).
