I just got this printer from a friend. They could not get rid of the error code 6000 and neither can I. Opening the cover does not result in the cartridge moving to the center. What to do?

The E744-6000 error code means there is an error with the the Wi-Fi module. If you have not already done so, I recommend you reset your unit using the steps below. By resetting the printer`s power, the print buffer is cleared and certain sensors are reset.
E, 1, 6 (LED display)

The ink has run out. Replace the ink cartridge and close the paper output cover.

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.
Description. Support Code 6004 generally means that there may be foreign material (such as scraps of paper) inside the printer. However, if no such material is found, your printer will require service.
Solution. There are several reasons for Error 5100 to appear, including a paper jam, an improperly seated ink tank, and more. Encoder (Timing) Strip on the printer needs cleaning. Manual cleaning can be done on some models.
E, 1, 6. Ink has run out. Replace the ink cartridge and close the Scanning Unit (Cover). If printing is in progress and you want to continue printing, press the machine`s Stop (Reset) button for at least 5 seconds with the ink cartridge installed.
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.
Error code E05

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.

Error Code 52.1M
ANSWER : Magenta laser error. The spinning motor bearings cause the squeal and that slows it down causing the error. You could try opening it and lubricating the motor shift with a drop of synthetic lubricant. Do not use more than a drop.
