Is there a way to get in and lube the gears or something?

Reset the calculator: Locate the reset button on the bottom or in the battery compartment and press it .
Clean the printer head: Use a soft, dry cloth to clean the printer head and ensure that there is no debris or paper stuck in the printer mechanism .

you are looking for resources to properly align the gears. I found a few resources that might be helpful:

Did you lube the sway bar mounting pads? If these are urethane, they will squeak like crazy without silicone lube.

id try lubing the feed rollers well the metal bars where they contact the chassis and lube gears and stepper motors. its been awhile since ive had my phazer. i traded it last year to my church pastor but try that. radio shack sells a teflon lubricator part no. 64-2301a and im certain amazon also sells them. ONE drop goes a LONG way. its also a miracle worker for pc fans, and household appliances as well as automotive where its not high heat. even bearings.

hope this helps you a tad sorry i cant be more of a help here but thought id pass a few personal experience in fixing electronics/mechanical tips along.

1- might be the scanning rail -- if you can open and lube LIGHTLY slide scanner back and forth ( w power off)
2- caould be Drum, some make a whistling/ hollow sound

have a mechanic check gear lube in the transmission

I would oil it. Printers need lube too. I would use graphite lube because it is thick and wont spread except from where you put it.

Good luck!

The problem actually is probably due to needing lucubration. I would apply graphite lube to any rollers or gears in the user serviceable area. print 100 blank pages to make sure that the lube is spread thoroughly through the printer.

Good Luck!

Probably paper dust stuck in the gears, you can try to blow it out with some compressed air, it could be due to differing humidity levels now that it is getting colder - I wouldn't worry too much over it, some noise is normal. Clicking, grinding, popping, however - that could mean something is about to go. But slight squeaking shouldn't be too much cause for worry, there's alot of moving parts in there to keep well lubed up... ;)

Take it apart, and clean and lube the components.

Most likely you need to replace the fuser assembly itself.
You can order it piece by piece, but you would have the cost of a heat roller, perssure roller, thermistor, gear and bushings. And that prices out more then a new fuser itself.
They can be purchased for the 200-230 dollar range.
If thats the route you want to take let me know. I can write out the instructions for replacement. It's not to hard to do.
