H3 ERROR CODE SHARP AL 1631

Exposure lamp error.

A H3 code means that there is a problem with the fuser unit. You can try to clear th code in service mode, but it may come back. You may have a blown thermister or thermal fuse or the fuser heat lamp. Good Luck

all the codes with(H4,H3,.......)can be removed by simulation 14

The H4 code indicates the fuser may have blown the thermistor. It also could be a false error code. Try this series to clear the error and if it returns, then you'll know for sure the fuser is the culprit. To reset press the following buttons:

1. Press this sequence: CLR-Exposure-CLR-Exposure
2. The display will go blank
3. enter "14", press "PRNT"
4. Press "CLR" several times to exit.

Give that a try and good luck.

Please verify your fuser parts components,the heater lamp,thermistors and thermofuse.Your heaterlamp or the thermostat is in open circuit or the thermistors circuit is defectly.

The fuser codes are only H2,H3 and H4. To reset , press C, Exposure, C, Exposure.Display goes off enter 14 press print.

H3 is a heater/fuser problem. Try to reset it by SIM 14. Press Clear , auto exposure, Clear and auto exposure and press copy key. check if H3 has been reset and LED is back to "00".

Try to reset the error code by pressing : C exp1 C exp1 14 start. if the problem still occur then you should change the heater lamp

Hello sir; that's a simple problem whayever you mention all the parts you replace are not necessary, if you can't reset H4,or H3 then you need to replace "THERMISTOR" that is the device to control the temperature, the parts #RDTCT0128FCZZ.

Hi, H3 is abnormal high tempeature in the fuser. Never had issues with the fan, probably you have a 'melt down', inspect the fuser through the sprung loaded flap and see if the three picker fingers that rest on the roller are melted. If they are then you require a fuser rebuild to include both fuser rollers, fingers, bearings and thermal fuse.

Cheers
