Question about Canon imageCLASS MF3240 All-In-One Laser Printer
I removed the toner cartridge because the indicator said: replace toner. Usually in a situation like this I remove the cartridge and give it a little shake and the cartridge lasts for a while longer. However, I found it difficult to remove the cartridge in the first place and I am not able to re install it. The right side of the cartridge doesn't seem to fit in place.
Possible the toner is got damaged while removing it with the printer and replace it with the new one.
