Sharp mx-2700n is ghosting the black and i would like to know how tocheck & clean drum and transfer felt cleaning assembly

You want to note the frequency of the ghost image. the drums are 1.5 inch round and the fuser rollers are a little bigger like 2 inch round and then the y1 trans belt is way bigger like 19 inches and the y2 belt is like 6 inches. If th ghost only happends with one color you could be pretty sure your problem is with that single drum. if it happends in multiple colors look at the other options first.

y2 and fuser you can see when opeing the right side of the machine
y2 is the wider rubber belt that is lower and the fuser is the hot hting at the top with that flip down cover.

y1 belt comes out with 4 blue screws after the front and right side of the machine are open, the toner waste container is out, and you line up the u shaped thing in the middle. turn in the direction indicted untill you see the green stick apear in the back threw the u.

The drums come out after you remove the developer units. with the machine off Open the front cover remove the toner waste container and loosen the two blue captured screws on either side of the plastic piece that covers the drum units. once those screws are loose check to make sure that the primary transfer unit is disengaged. there is a u shaped thing in the middle that needs to line up. if it is not lined up then rotate the blue screw in the direction indicated until it is. flip the whole plastic bar up if it catches in the middle don't force it rotate that screw. if it catches on the sides then just push it harder the sides make a pop noise sometimes before they give. each of the developer units have a flip up cover that gives you access to another blue captured screw. Pull on the cover from the bottom up then loosen the screw and the developer units will pull towards you. after you pull a dv unit the corresponding drum unit comes out by pressing a button down. the drum units are rebuildable in this machine. there are two blue plastic screws in the end holding a bronze bushing, and two silver plastic screws holding a cover on. there is a snap on side cover that will release the grid. and then three blue screws to get the wiper out. in general on sharps it is ok to pull out blue screws, but never ever pull out red screws.

Let me know if you need more hlep.
