Brand: Brother Model: HL-2040 Problem: cannot print, paper error, red light blink, did not feed paper. What should i do? thanks.

I tried most of the suggested fix with no luck. My last resort, I removed the toner cartridge, removed the toner half and opened the clip holding the drum. I slide the rod out carefully removing BUT remembering how things are inserted on both sides. (PREPARE: rubber globes, isopropyl 99% alcohol, 4 cotton balls and clean brush). The drum is light sensitive so do not exposee it to direct sunlight. I used the cotton balls with 99% isopropyl alcohol to clean the drum, set it standing up leaning just the top part to a wall or box. Clean the rest with brush. After assembly back, use the q-tip on iso. alcohol and clean the corona string (its the part where you slide the blue slider suggested by others). OR just ignore everything and buy a new set of toner drum assy. THIS IS THE ONLY THING THAT FIXED MY HL-2040. I tried most of the suggested fix with no luck.
