Yep, the fuser fan is he one that fails. You can remove the top and rear covers and then carefully remove the shrouding and whatever else makes it easy to get at.
What you can do if you dont have a fan handy is, remove the silver label on the fan. Behind that label there is a black rubber cap over the bearing in the fan. You can flush that bearing out with alcohol several times and then use a very highly refined oil , to lubricate it. Just pretty much fill up that little hole around the bearing, put the rubber cap back on and then wipe it clean with alcohol and tape it back on.
If you need a fan, Go onto google. Type in ( the parts drop) not parenthesise.and call them, Ask for Britt, I dont work for them, but they are 100 percent professional and will charge you a fair price.
Cleaning and lubing will fix it about 60 percent of the time.

Hey, I know this is an old post, but if anyone else is having fan errors on there 7700, 7750, or 7760 you should replace the three fans to clear the error (part# 7750-Z2 ). Here is a video that shows you how to locate and replace all three fans.

This error code means the life of the black developer is at its end. It is probably time to replace all four developers and the only reset is replacing the engine control board.

The costs will come around 1000usd I recommend you buy a new one.

Phaser 6360 laser failure code 07


Hi,

Yeah I had a look at the website there too, try powering down again and plugging it out for a longer period of time. You need to get the whole machine to reset and loose all saved info in the bios. Also cleaning it out of all loose toner on any contacts might help!

Xerox 7750 fan failure code


That is the fuser fan either running slow or stalled. It is located on the back, looking from the back on the upper left. You will see the slotted opening.
You have to remove the side covers and the top cover to access it, Sometimes taking off the silver sticker in the middle, removing the rubber cap and oiling it will help.
To buy one. Go onto google and search for " the parts drop". Call them and ask for Britt or Joe, they will know what fan and be fair on a price.
Taking your time it should take half an hour to an hour to replace. Not hard, just take your time and make sure you note how you disassemble. You will be fine.

There is a motor in the laser called the polyogon motor, It turns the mirrors in the laser.
It most likely is not starting fast enough.The laser isnt that hard to remove. But if it has failed, it is pretty expensive.
Let me know if you want to attempt to pull it.

I am geeting error code 48 on my phaser 7750dn


that is a fan failure code, Either the Fuser fan ( most likely) behind the back cover near the front.Low voltage power supply fan or rear cover fan is not operating.
Most of the time it is the fuser fan that is not running or even if its running slow it will give you that error code.

Here are the notes
Problem:
    Fan Failure Message (Code / Error 48)
Cause:
    The machine logic detected a failure of the Fuser fan, LVPS fan or rear fan.
Solution: thumbsup.gif Fixed! thumbsdn.gif Did not fix.
  1. Insure there is adequate ventilation around printer. Refer to Section 1 of Service Manual for required clearances.
  2. Follow the procedure in Chapter 3 for this error.
  3. This problem can be very intermittent. Fans can work in diagnostics and fail in the middle of large print jobs. If unable to duplicate problem replace all 3 fans.
  4. Use service diagnostics to verify the Fuser, LVPS, and ROS fans. These fans have a third wire which provides feedback to the Engine Board.
  5. Visually check each or these fans for a build up of dust or toner.
  6. There is a correction to this procedure in the Service Manual. The fans that can cause this error are the Fuser, LVPS, and ROS(laser fan). Not the Rear fan. The rear and bottom (developer) fans are not monitored by the system and won't generate this error.
Parts that may resolve this issue are:
  • FAN ASSEMBLY, FUSER (63%)
  • FAN ASSY; LOW VOLTAGE POWER SUPPLY (45%)
  • FAN REAR ASSEMBLY (Laser Fan) (25%)

Fan Failure Error 54


1 of 2 things.
You need to clean or replace the fan.
You have to remove the back, right side and top cover to access that fan.It is near the back just behind the fuser module.
It could also be the low voltage power supply fan. Most likely the fuser fan.
Once you remove the fan, there is a label on it, remove the label, There is a rubber plug behind the label, remove the plug and drip some lubricant into the fan. Reassembly and it should be ok.
I would recommend replacing the defective fan though.
Here is a very reliable part source.
https://www.partsdrop.com/store/

If you call ask for Britt and specify the model number and that you need a fuser fan and probably order a Power supply fan, Neither are very expensive.
Have both on hand to be 100 percent sure the problem is resolved, But its a 90 percent fuser fan failure code. It operated in a heated area and can dry out faster.
