Great!

As a reminder, originally the drum stuck inside and I follow some guides here to take the drum out. Then I pull the rotary to "home" position. At that time, I unhook the pressure hook. Then the "problem" happen.

Thank you very much.

Looking at this picture, with the timing so far out, it looks like the drum clamp may have got caught in the disposal hooks. Maybe why your drum was difficult to take out. I think even if you do manage to get the timing in, there may be some under lying issues going on there. Basically, something caused to timing to go out and getting the timing back in won't be the end of your troubles I fear.

Thanks guys and I am still waiting for a services manual from my friend in order to work out what joelsa12 recommended. It looks like a simple problem but end up it is not as simple as I thought.

I will post an update...

Service Manual???

Find the feed clutch, pull off the spring that is conected to the casing around the clutch. loosen three screws on frame that tighten the drive belt with the clutch. do not let the gear on the main shaft turn. this is the disk on the left of the machine that should have the dot right in the middle of the sensor. You can lock it down if you would like, but it is easier to just loosen the belt around the main motor. (disc on the right is attached to this) and turn the main motor with out letting it turn the belt. I would imagine that you put in a different color and the drum had been sitting around for awhile. this caused the clamp to go in the disposal due to the fact that there was a lot of ink built up under the clamp. the whole process should take 5 mins. if that. i am happy that you are getting a manual. most people would not go that far. pm me if you would like to call me and i will tell you how to do it if you can not figure it out.

Great!

You are great, joelsa12.

I will first study what you said and make sure I understand what you described. Then I will do the "5 minutes task". Ha ha ha... I don't think it takes me 5 minutes. Sure I will update the result here.

Thanks!
