I CAN'T FIND THE POSITION OF THE connectors for

Most common problem is the electrical connector on the fusing unit or the connector that the fusing unit connects to inside the machine is broken. So when you push the Fusing Unit in to the machine the connector moves out of position and doesn't connect properly.

Main motor issue check fuser unit (hot part) check paper jams durum installed correctly image units etc

The fuser needs to be removed from the copier first. If you have the part it is not to hard to take the fuser out. Turn the copier "OFF" first & unplug the copier, remove the transfer unit from the right side, then remove the back panel of the copier ( 5 screws ), then unplug the fuser unit ( 3 connector ) , then reove the top right cover ( 2 screws ), then you can see the 2 top screws & the bottom 3 screws, remove them and the fuser should pull out toward you. Replaced the broken fulcrum arm and reinstall the fuser in revese...... Good Luck

The value of R024 and R025 is represented by color codes 'red red yellow' which means 100k ohm and 1/4 watts resistors.

This means there is a problem in the fuser unit area.
Remedy
Check the fuser unit gear if its broken. Replace if out.
Check if the separator pawls are out of position. Adjust to its position.
Check if the fuser separator spring is out. Return it to its place.

It sound like you have a thermistor that either has a buildup on it or it is not contacting the fuser roller. I would remove the fuser, disassy and clean every component. Reinstall and usually the problems go away. Let me know if you need more assistance.

H2 or 2H is related to a fuser under heat or overheat.
Try this first,

Performing a Fault Reset 14 will reset your WorkCentre and will help to clear error codes.

1. Find the pink Clear button on the Control Panel of the WorkCentre.
2. Find the button below the word Auto.
3. Press these buttons in the following sequence: [Clear], [Auto], [Clear], [Auto] NOTE: All of the lights on the Control Panel should go out and the LED Display should go blank. If the lights do not go out, then repeat step 3 until they do. It may be necessary to increase or decrease the pace of the [Clear], [Auto], [Clear], [Auto] sequence.
   
4. Press the [10's] key one time and the [1's] key four times to enter '14' in the LED Display, as if you were to make 14 copies.
5. Press the green [Start] button.
6. Press the pink [Clear] button two times.
7. The WorkCentre should now warm up and come to ready.
8. If the above steps do not clear the error code, repeat steps 3 to 6 a second time.

If this does not clear the problem the fuser will need replaced.
