Question about Canon imageCLASS MF6530 Monochrome Laser Copier/Printer
There may be a much more simple reason :
Reason : the shutter of the laser is not opened by the cartridge. (I had same problem, and solved it). This is a defect of this printer and it results in blank pages. Solved in five minutes. Try it. If it does not work for you, it cannot do any harm.
Open the door and remove the toner. look inside and you will see in the upper part a rectangular window in the metal bar. This window is shut by a metal plate behind when the door is open. Try to raise it with a knife. This is the problem. Now, this shutter is here only for legal reasons (security to prevent the laser beam going out when door open, but when the door is opened the power is shut so...). Cut a piece of plastic just the width of the opening, fold it at angle in the form or an L, then place it on the left side of the opening, so that the shutter can no longer go down. A piece of scotch to fix it in place and you are done.
Now, if it works and you are grateful, I am interested in empty cartridges.If you have some tell me. Thanks.

I was able to fix the problem using a combination of the advice above. Being a novice at this, the advice was a little unclear to me so let me see if I can explain what I did in hopes that it will help someone else.

I also had the same problem and today managed to fix it. I am nowhere near an experience printer fixer so I have no idea whether this will work for others, but this no-print issue seems to be pervasive so I thought I would share what worked for me.
Here's what I did:
(1) Turn off and unplug printer.
(2) Open the left cover (this is the door where you put the toner cartridge in).
(3) Remove the toner cartridge.
(4) Using a flashlight, you will be able to see a small rectangular flap or shutter that sits just behind where the toner cartridge normally sits. The shutter might be about 3 inches long and one quarter inch high. I don't know for sure, but I assume that this is the "laser scanner shutter door" referred to by Colbert.
(5) Take a flathead screwdriver and GENTLY insert it beneath the shudder and GENTLY move the shutter up. When I did this there was some resistance and the shutter seemed to be stuck. I moved it up and down a couple of times and it seemed to move easier. I also followed the shutter door over to the right and up a little, where you can sort of see where the toner cartridge arm connects to the arm that opens this shutter. I sort of gently manipulated this arm a couple of times with my screwdriver as well to try to make sure it was free.
I'm not sure if this will work for others, but it worked for me. It only takes a few minutes.

I had the some problem. This is what I did to fix it. When you fully open the toner door you'll see a flap that swings down. Before closing the toner door swing the flap to the close position and listen for something that seems to be opening in side the copier. Keep closing the flap till you hear this noise. Close the toner door. Copier should work fine.

Okay easy to fix, extremely easy actually. First turn off the copier and remove the toner cartridge. Then look inside and on the inside backwall near the top you will see a metal piece and a small metal flap inside. Use a small screwdriver and on either side see if it lifts. If it does, then the shutter arm has broken, but not to worry. Take a small wad of paper, put a piece of tape on it and jam the ****** in the right side propping up the laser shutter. Make sure the paper wad is small enough to clear the laser glass. Reinstall the toner cartridge after you are satisfied the wad of paper is jammed in that sucka tightly. Close the back toner cart door and it's fixed. Turn the copier on and it should print with no hassles from here on in. Worked on mine :D

Just had the same problem... talked my sweetheart through using the comments that were added here - thought I'd do the same for the next poor soul with this problem.
Over the phone I was able to describe the laser "shutter door" location. She used a plastic zip tie piece to hold the door open...
And got her first copy!! Just in time for the week long conference to start.. thank goodness.
Our experience - definitely the stupid laser door.
Thanks everyone for taking the time to input your comments and work arounds... Thanks Canon for nothing.

We have the same problem at our office every time the power goes out. Our solution: Unplug power from the back of the machine for a few seconds. When you plug it back in, press some random buttons. After that, change the density to as dark as it will go. This, I guess, lets more ink out? Anyway, it prints fine after that. No removing of the control panel or anything like that.

Laser Shutter that opens and closes when side door is closed and opened is sticking shut.
Take covers off machine to expose laser unit and open and close side door
and observe metal laser shutter. Remove it and problem solved.

This worked for me, but not sure it will work for all. I took a rubber mallet and pounded the printer on the four sides five times each. I then shook the toner three times. I placed it in and opened and closed the flaps twice. I spun the printer around one time and then voila! It was running just fine.

The best way to take care of the laser shutter problem is to totaly remove it. theres nothing in there that will tell the machine the toner isent in the machine. this is a perment fix. theres a little more work involved but worth it.
you will need to remove the front cover. control pannel and the eject tray.
Hope this helps

OK Guys, I had a slight variation on this problem - -
I also did not get any image printing, even w/ a new toner cartridge.
It seems that the metal connectors that contact the toner cartridge are critical, but my problem was related but, actually lower down than that. There is a little plastic partition that buddies right up with the scanner door flap on the toner cartridge. In my case, the scanner door flap was opening fine, but the secondary flap had a metal contact that was supposed to transmit electricity to a pivot bar that held that secondary flap. All I did was I took a screw driver and pushed the metal connector down so it dragged nicely against the pivot bar - "as it wanted to". I tested it and Voila - It worked. So, the flaw in MF6520 Cannon photocopiers seems to be contacts with and around the toner cartridge, but definitely check all contacts.

You must remove all the covers. Then on the front side.... you can see the arm that actuates the Laser scanner shutter door. It comes off fairly easily . it must be removed then merely file the edges down. A burr develops that needs to be filed down. the edges are really really sharp so be careful. Also I have seen the Arm that opens the Toner shutter door be broken as well.Actually the hinge projection on one side of the toner is what breaks and the arm doesnt swing up quite enough to open the door ... as well as hitting the scanner door.
Hope this helps someone.

When you close the door to the printer, there's something that opens the flap to the laser unit. This makes it so the laser can shine down on the drum. The flap isn't openeing when you close the door. You'll have to look at the flap, and then follow all the mechanisms that eventually lead to the door. There's a break in it somewhere.
