Ricoh mp 2000 print out black horizontal lines stain

[eckstan]

My mp 2000 started making black horizontal lines stain each time print out or make a photocopy.
I brought out the OPC drum unit, clean the opc drum, charger roller, and the cleaning blade and then reinstalled all components.
However I got sc302 error after powering The machine and I've to repeat the cleaning process all over, before error code left the screen yet the line stains are still coming out.
I did a replacement of the OPC drum and cleaning blade and yet the black lines kept being printed out.
I've to put off the machine for about 3 hours and upon reprinting there wasn't any stain instead there is a blank lines at an interval equivalent to the circumference of the OPC drum.
Please help me out on what to do

The terms horizontal and vertical are meaningless when talking about copies and print outs. Now can you clarify whether the stains are parallel to the direction on paper travel or not.

The diameter of the hot roller is very close to hat of the drum.

1) print outs of the issue WITH paper feed direction noted would be GREAT to have
2) after replacing parts did you run any calibrations on the machine (init drum?)
3) life used on ALL consumables and service parts
4) TOTAL page counts
5) what does the fuser assmy look like?
6) since on both prints and copy .. rule out optics
7) genuine OEM parts/Supplies or 3rd party/compatibles?
8) I take it you are an End User.Owner?
