C3851 Abnormal Low Temp. (Heater):

• The temperature of the Heating Roller Thermistor/ 1 (TH1) is lower than a given level of degree for 1 second or more uninterruptedly during
Ready mode, Low Power mode or printing.
• The temperature of the Heating Roller Thermistor/ 2 (TH3) is lower than a given level of degree for 1 second or more uninterruptedly during

Try resetting. To reset a Rank A error follow these steps:
1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
If the error recurrs then do the following:
1 Check the Fusing Unit for correct installation (whether it is secured in position).
2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary.
3 Change Fusing Unit
4 Change PWB-M
5 Change PU1

My dell 5210 is showing a 920.16 Service Fuser Error. How I fix this/trouble shoot?

920 Fuser Error indicates the Fuser is below temperature while printing. The fuser, melts or fuses the toner to the media and has a heat roller and a pressure roller. The heated roller is heated by a halogen lamp or in some cases a solid state ceramic heating element and is subject to failure.

If this is the first time you have seen the error

    1. Power the printer off.
    2. Leave the printer powered off for 20 to 30 seconds.
    3. Power the printer back on. If it comes up to the Ready state, try printing again.
      • If the fuser error does not return, continue using the printer as normal but observe it closely over the next few days to see if the error returns.
      • If the fuser error returns on power-up or if the error returns as soon as you try to print or at a later date, the printer will probably require service to correct the issue.
  1. One thing that you can check as well (since it is a "under temperature" error), is to make sure the printer is not plugged in to a UPS/surge protector. The printer may not be getting enough electricity to heat up the fuser. Try plugin it in to directly to the wall/different outlet and see if the error persists.

If this does not correct it, you need to replace the fuser.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response
Thanks, Joe

I am trying to print out an e-mail and all that prints is the header (From, Date, To, Subject)

Go to and look under support for your model. There's a fix for that problem that you download and install to the printer. Also in internet tools you'll find choices to set for printing from the internet.

I think you have misplaced the cartridges, i.e. , you have placed them into wrong slots.
You may need to contact you local support to get the issue fixed.

You can log into the device from your web browser to set the default subject line of the device.

Set up a 1-touch and you can also enter the subject line there.

When entering the address manually you may need to navigatge a couple of menus in order to find this option.
