Error 6502 mainly indicates an error in the sensor position of the ink tank. This means that your printer is unable to recognize the ink cartridge chips when the error code 6502 generates. Because of this, your printer will stop printing or scanning. In most cases, the LED blockage is another reason.
If you see Support Code 6502, it means that there is a problem with the ink tank position sensor.
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.
This is an error that results from a mistake in the arithmetic or the numeric value executed in a statement. For example, this error message could result from attempting to execute a statement by assigning an integer a value greater than 99 when the variable is set to NUMBER(2).
ORA-06502: pl/sql: numeric or value error: null index table key value. This means that either: Your index variable is not getting initialized, or. Your index variable is getting set to NULL somewhere in the code.
First, try rebooting your computer and turning your scanner off for a few minutes, then back on. Doing this corrects more computer and device issues than you may expect. Besides turning the scanner off, disconnect the power cord – this causes a more complete hardware reset.
In computing, an error code (or a return code) is a numeric or alphanumeric code that indicates the nature of an error and, when possible, why it occurred.
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.

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.
