I hope you still have your copier and have not yet sent it in. I had the same problem and when I called Canon Tech support, they told me to go buy a new CANON brand toner cartridge that costs from $150 to $180 each to see if it would fix the problem. Obviously, if this did not fix the problem, I cannot return the toner for a refund. I was using a knock off brand that cost me $40.

I found that the problem is a metal shutter that is inside the machine behind the toner cartridge. It is a metal shutter about 1/4 inch by 4 inches that moves up and down to protect the user from the laser. Your shutter is not moving up out of the way of the laser. What I did was grab the center of this shutter with a hemostat (or long thin pliers) so that it bends this shutter just a little bit, then I pushed the shutter upwards with a butter knife. This little bend in the metal shutter causes the shutter to stay in an upright position by friction of metal on metal. Now it copies fine, even with an offbrand toner cartridge. It saved me hundreds of dollars on repairs or replacement parts.

I think that Canon tech knows about this, but they make more money when they replace a whole new laser unit for you or charge you for repairs.

Well chance are they will make you send it back, they will most likely NOT come out since you bought this product from Staples or Office Maxs. If they do tell you that they are coming out , tell them that a Premier Authorized Imageclass Canon dealer, adviced the service technician that they should bring a Laser unit with them or repair yours. Yes we areCanon Authorized Dealers- for the Imageclass series.

The problem with these units are that the Shutter on the laser unit " the spring" breaks or pops off and refuses to open the shutter when the cartidge is installed. So chances are this is a defect from Canon an is a common problem. So tell the Technician from Canon to " BRING A LASER UNIT"

I changed my toner cartridge today and now it's not copying

Having 2 (defective?) cartridges that behave in exactly the same way seems too unlikely to me. So I have to ask the obvious question....did you pull the seal to release the toner? If it's an original there should be one, if it's remanufactured, there may or may not be one on it.

Printing and copying almost blank pages

Ussally drum/toner would fix, will not be fuser, I would suspect Hi voltage board or laser unit, In australia these machines carry a 2 year return to base warranty.

Try reseting the drum counter, this also resets Bias voltage, might be your problem. open front cover with power on and press set, arrow to change drom and select yes.

Otherwise it would be a high voltage board problem, possibility alsoexist that it could be laser unit

Check status page for "71" errors, menu * 2 8 6 4 very very fast, machine will beep "maintence displays" then 77 to print out status page, 99 to return to normal.

Can not receive faxes or blank pages com thru!

Can you make a copy and get a good print? Does the blank pages come from different people? If you still get a blank from making a copy, then try a different toner and or drum unit. Hopefully it is still under warranty.
