1. If that does not clear the fuser error, make sure the printer is plugged directly into the wall outlet and not into a surge device or power strip. (A surge device/power strip can cause a fuser error to occur on the printer.) 
2. Look into the printer. Make sure there is no sheet of paper or other item stuck in the fuser unit. 
3. If none of these steps clear the fuser error, the printer will probably need to be serviced as the fuser unit may be failing. 

Symptoms

Error: "920 Fuser Error" Error: "921 Fuser Error" Error: "922 Fuser Error" Error: "923 Fuser Error" Error: "92 Fuser Error"

Notes

These printers are currently not covered by any telephone support.

Causes

The most likely problem is that the fuser unit is failing and will need to be replaced.

The 9-7/970/927 error codes are all Fan Stall error messages. They appear on the different printer models as follows:

4019 printer models:  9 - 7 fan stall error
4029 and Winwriter 600 model printers:  970 fan stall error
4039 and the Optra R and Optra L (4049) printer models:  927 fan stall error

Start by checking the exhaust fan on your printer:

1. Stand in front of your printer. You will see the vent for the fan along the left-hand side of the printer. The fan is just on the inside of that cover.
2. Power off the printer.
3. Open the printer's top lid. Look on the inside of the top lid, along the left-hand side.
4. Look for a metal "circle" or wheel. It will be partially obstructed by a piece of black plastic. That "wheel" is the exhaust fan.
5. The fan can sometimes get stuck. Try spinning it a few times.
6. If it does not spin freely, there may be some sort of obstruction or problem with the fan. See if there is anything obstructing the fan.
• If there is some kind of obstruction, try to remove the object.
• If nothing appears to be blocking the fan, the printer will probably need service to fix the problem. 
7. If the fan seems to spin freely, close the lid and power on the printer.
8. When the printer comes up to the READY status, try printing.
9. If the error does not return, continue using the printer but keep a close eye on it to see if the Fan Stall error returns. We recommend  leaving the printer powered off overnight for the next few days if no one is monitoring it.
10. If the error does not return in a week, your printer should be fine.
11. If the error returns after you power on the printer or within a few days after you get it up and running again, do the following:
• Make sure the printer is plugged straight to the wall and NOT through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer which can trigger a fan failure error. Even if the printer has worked on this surge device for months, you should try operating the printer plugged directly into the wall.

If you are a technician working on a printer that is posting a Fan Stall error, there is another part you can check. The main fan is held in place by a black plastic piece called a "plenum assembly". If this plenum assembly cracks or breaks, it will allow the fan to move around and thus cause a Fan Stall error.

1. Check to see if the plenum assembly needs to be replaced before ordering another fan assembly.
2. If the fan assembly and the plenum assembly both seem to be working as designed, you should check the printer's engine/system board next.

Note: If you are working on a 4019 printer that is posting a 9 - 7 fan stall error, you may want to replace the plenum assembly if you replace the fan unit. This is because of a design change to the fan which sometimes requires that the plenum assembly be replaced as well.

Printer is Making a Squeaking Noise

The most likely sources of a squeaking noise on your printer are:

the toner cartridge
the front set of exit rollers
the lower rear feed rollers

• If you keep extra toner cartridges in stock, try another toner cartridge. You can also try a used cartridge or one from a working printer of the same model. Switch the toner cartridge to see if the cartridge you currently have installed is the cause of the squeaking.
  
  
• Open the lid and look at the front set of exit rollers. Make sure they are clean and no small pieces of paper are caught on a roller. You should be able to turn them by hand using the bottom roller to see if they are causing the squeaking noise.
  
  
• The best way to check the lower rear feed rollers is to look for any small pieces of paper jammed back there. The best way to check those rollers is to open the top lid and remove the toner cartridge. Look all the way into the back of the printer. You can also look to see if anything is jammed by removing paper tray 1. Look up into the slot where tray 1 went. Look all the way into the back to see if a sheet of paper is jammed back there. If the problem turns out to be one of the feed rollers themselves, it will require a technician to replace them.
  
  
• If you have added any additional feed options, like a tray 2 or 3 option, duplex option, or envelope feeder, remove these options and try printing a few pages.
• If the noise goes away when you remove the options, reattach them one at a time.
• If the noise returns on one specific option, a roller on that option may be the cause of the squeaking noise.
• If the squeaking noise continues on the base printer when all of the feed options are removed, the squeaking noise will be coming from a roller in the main base printer part.

Symptoms

Noisy printer Printer is too loud Printer is making a squeaking noise Squeaking rollers Printer squeaks

Causes

Very few printer parts would produce a squeaking sound. A squeaking noise usually indicates a roller of some sort.
