My MF8280CW printer works just fine and about 5 years old. But, when print output starts,runs,ends it makes a new noise that sounds like plastic parts sliding/rotating against each other and is squeaky oscillating sound. Not serious today but seems like a small dab of silicone lube would fix it.
What should I use for lube, where to apply lube, how to open machine outer case to access the squeaky areas?
Machine out of warranty. I am not paying Canon service to fix a simple squeak. I am a product development design engineer and am very capable repair tech.
Please advise and provide link to repair manual.
