Question about Xerox Phaser 7400/DXF Laser Printer
I have a Xerox Phaser 7400 that has been refurbished so it is not under warranty by manufacturer. It is a network printer, so has multiple users. The problem is that it stopped printing, with a message saying that waste cartridge needs to be replaced. I shook out the cartridge, but printer still insisted I replace the cartridge. I bought a brand new waste cartridge and installed it, but it is still saying to replace waste cartridge. I don't know if this particular detail helps, but I also noticed at one point of messing with the waste cartridge, that a spring came loose out of nowhere. I have no idea what the spring went to, or what it was a part of. Did that have anything to do with the errors I'm getting? Please help. All the printing in our workplace is at a halt until we can get this figured out. Thanks in advance.
I just fixed mine. You need part #604K47890 Gear Coupling Assembly Kit. Cheapest I found was $6.99 at www.sparepartswarehouse.com plus $13.95 s/h. Remove the waste cartridge & you can see the white plastic gear. I tried to disassemble the printer (using service manual) in order to replace this part. Good luck. It looks like you need to take the WHOLE thing apart. Easier method is to get a drill or dremel & grind away the thin metal to make the whole slightly larger. Just be careful with the dust/particles. I did this & it worked perfectly.
