What does code H 3 mean when the copier is turned on?


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

H 4 code flashing


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.

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.

How to locate and replace copier exhaust fan


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

Andy
