You have non-genuine black toner that is more often to fail in print quality than genuine ones. If you replace black toner with the different one those black vertical lines on the left side will be gone.

Also, your all 3 colour toner cartridges are empty, if you want to print in colour you will need to replace them too,  I would recommend if you are printing only in black&white to purchase a cheapest b&w laser printer.
