Connect the USB cable to the Printer

Connect the flat end of the USB cable (1) to the computer (type-A receptacle). Connect the other end of the cable to the printer (2) (type-B receptacle). Note: The USB connector will only fit in one-direction into the type-B receptacle on the printer.

When you see P07 error code on your Canon printer, then you should know that it`s due to ink overflow issues. However, there is nothing to worry because your printer already has a system which you can use to clean the excess ink.
Change your USB Cable or the USB Port

Alternatively, you can also use a USB cable recommended by Canon. If it`s not the cable, then check your USB port. If your camera doesn`t connect to your PC, then try plugging it again into a different USB terminal. Most PCs and laptops feature multiple USB ports.

The easiest way to connect the Canon printer to the computer is via a USB cable. It`s the traditional method of connecting devices. One end of the USB remains connected to the printer, and the other must be connected to the computer`s USB port.

Canon printers produce error codes for one of several reasons: The settings for your printer might not be compatible with the document you`re trying to print. The loading bay for your paper might have become lodged with paper or you`re using the wrong type of paper.
According to Canon, Error 06 indicates a fault of the sensor cleaning module.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
About the difference from a hard reset

Hard resets delete all the registered files, such as the form data saved in the RAM of the printer, but soft resets do not delete them. Cancel printing from the computer. Press [ ] ( Reset). Select [Soft Reset] using [ ] and [ ], and then press [OK].

Error Code 51.1 says Printer Error No Kidding.lol
ANSWER : Sometimes turning off and on will allow you to print a few pages. The error is a beam detect error. The only real fix is to replace the laser scanner unit. Could be a loose connector on the scanner or DC controller from the scanner. That’s unlikely. You could try the only other free fix which is to open the scanner assy. and clean all the mirrors inside. The dust could obstruct the laser beam enough to cause the detect error.
