I have the same "grinding" problem with a print head that keeps moving back and forth and not working that other people on here describe. Every solution talks about cleaning the glass, however, they don't tell you how to actually lift the top frame off to GET TO the glass. I'm not talking about the little strip of glass on the left, I'm talking about the Big Enchilada, giant piece of glass that covers the top. I've gotten as far as undoing all the screws, taking the left strip of glass off and the front button panel completely off. It LOOKS like the plastic frame around the glass should lift right up -- except that IT DOESN'T. I am at my wits' end...would someone please instruct me from here???

Try unplugging the printer and opening the door where the printing heads are, and make the sure belt that moves the print carriage back and forth is not broken or damaged. Pull the belt so that the print carriage is moved to a different position than where it usually parks, and that may unjam or reset the mechanism. The grinding sound might be coming from the scanning mechanism, or the scanning sheet feeder. Try manually turning the wheels for the feeder and make sure they turn.
This generally occurs when the tracking ribbon becomes dirty and the print head travel cannot be tracked. Open the cover as you would to change your ink cartridge and locate the clear plastic strip behind the print head. Very gently wipe the ink residue from the strip using a cloth damp with water. You should be able to move the print head manually enough to clean the entire strip. Again be very careful as the strip hooks on the left side and is very difficult to reattach.
The 6A00 is a Canon generic code for paper path jam.
Solution 1: Move the printhead carriage back and forth a few times.
Solution 2: Check the purge unit: Moving the print head assembly will not clear a purge unit if its jammed with paper, paper clips, push pins, screws, cookie crisp, flower bud pods or the like.
Solution 3: Press the ink pads down in the purge unit. Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

If you will notice that there is a transparent film that the printhead goes through to be able to print. That transpatent film is actually coded to be able to tell the print head in which direction and when to print characters. It is dirty and you need to take like a q-tip with isopropyl alcohol to clean it so it knows where to print and does not go back and forth to find a position to print. God bless you.
That is a print head position fault.
The stainless steel print block that holds the print head shaft may have ink in it not allowing the print head to pivot back and forth.
There may be one of the cables keeping the print head moving freely.
The machine was powered off or lost power and the wiper is stuck between the print head and the drum.
You pretty much need to take the covers off to determine the problem. And it may require removing the print head itself. I would not recommend that.
What you can do to prevent the problem in the future is make sure the printer is level front to back and side to side.
There is a possibility that the print head itself has failed, but that is the least likely problem, albeit possible.
Grinding noise is most likely caused by the carriage lock getting stuck and holding the print head at the home position. The noise is caused by the toothed belt that pulls the head back and forth, skipping over the splines on the motor drive wheel.
If you have been able to print since the problem occurred, chances are that it has freed itself up and will be fine.
Regarding the loss of cyan & magenta output, follow the solution given in my previous posts to complete a manual under-head cleaning cycle. This should get you going.
