Make sure the copier is in "copy" mode.
To get into service mode press the following keys one after the other "P" key - "interupt" key - "clear" key - "interupt" key (do not play around with setting in service mode as this can render your copier useless)
enter 22 and press "start" enter "7" and press start. This should display the admin code.
Restart the copier and you should be good to go.

I'm sorry for not getting back to you sooner - I lost track of this question. If you still need this info here it is :
H3-00 indicates a temperature problem in the fuser unit. not reaching a certain temperature within a certain time.
It could be a thermostat or thermistor problem - both monitor temperature. you could remove the fuser unit and make sure these items are clean - no build up on them. there should be a center and side thermistor.
You can reset the error code in SIM mode by pressing the following keys one after the other "P" "interupt" "C" "interupt" then 14 and start/copy key. confirm if required. make sure the copier is restarted afterwards.
If the error persists then you may need new thermistors.
Hope this helps.
