It reads low heat error....what does that mean?

Dear
low heat error means the temp. of fusser assy. was not achieved during the specified time. some times occur during low voltage supply and reset after s/w OFF-ON.
Open heat error means there is no electrical connection to the heater heater of the fusser assy. It has tob either repaired or replaced with new one. mostly the thermostat is responsible.
Thanks.

Remove the fuser lamp and put it back in place, it is not heating properly.

Pls do the following

[Low Heat Error]

There is a problem in the fuser
unit.

Unplug the power cord and plug it back
in. If the problem persists, please
contact a service representative.

Thank you.........

The "low heat" probably means that something is wrong with the fuser. The fuser is the key piece of printer hardware that heats up to "fuse" toner to paper. You should probably have an electronics repair guy have a look at it.

Low heat means either the fuser is not heating up or it is not sensed properly. you can find a new fuser at www.precisionroller.com but the low voltage power supply could be bad as well.

the fuser is defective and needs to be replaced.

H4-00 means heat roller low temperature detection. It usuallly caused by 3 things :

1. The machine hang : You simply reset the error code by pressing : # * C * then input 14 then start.
2. If the error still displayed, open the side cover, feel the fusing unit ( don't touch, it is hot ), if the
fusing unit feels cold then the problem is the heater lamp ( inside the upper heater roller,
connected with anti heat cable and big connector ), you should replace it.
3. If the fusing unit feels warm or hot then the problem is the thermistor ( connected with small cable
and connector ), replace it.

Kenstar is displaying F8 error

ther is a prob in your fusing unit, chances are the thermistor is not working, if you can still feel some heat in this area, either the lamps are working fine but the sensing device fails to read the actual temp.

you need a tech to correct this prob
