Hello,
I just bought and sell a Canon IR C4080i, when I tested it, it fully works. But when I delivered it to my customer, it doesn't work. I had an error everytime I would print. At the beginning I thought it was a software problem, so, I reset some components of the printer via the service mode.
But when I turn it ON, the printer shown an error code, an this error code, changed everytime I turn it off and on again.
Then, I saw in internet that this error codes was hardware problem, so, I decided to open up the back cover of the printer to access to the motherboard. Given the dust on the components, I decided to remove all the cards, clean the contacts and try to turn the printer ON again. And it was working ! Then, I made factory reset via the UI of the printer, and after a while, the printer turn OFF and ON again.
But now when I want to print or copy, the printer jamming immediately... I hear the paper feed in the printer, but some seconds after, the printer stop with paper jam alert on the screen without error codes, and when I open the fusing unit drawer to eliminate the paper jam, I can see the sheet placed on the fusing unit just before the fusing rollers, and the sheet is not print (no toner on it) or crumple.
And since the factory reset, when I try to scan with the feeder on the top (not with the glass) I have scan paper jam error immediately I put my paper sheet, and the only way to make it disappear, is to turn the printer OFF and ON again.
I tried to print/copy with A3/A4, to change the paper format in the paper drawer, I cleaned all the sensor, I have a finishing unit (staples) and I try to remove/unplug it, but nothing work. I have access to the service mode, and I can change some hardware parts if needed.
I 'm really desperate. When I tested it was working well (no paper jam), and when I deliver it, all this problem appears, I conclude that the first one was due to the dust, but I don't understand why it jamming instantly... The printer wasn't hit during the transportation, we just make roll it on the asphalt for some meters to bring it to my customer's office.
I really hope you could help me.
Thanks a lot for all.
Alexandre
