folks, finally got the part in via aliexpress. tks to d. spencer parts source ref. i was able to remove the old board on back right side of printer from front. got it all in, powered on, it goes through the initialization phase partially, (before it didn’t go this far as grunting through this phase), but it stopped with a the red light bar on. i tried power down/back on but the initial cycle up stopped short with the large red bar come on midway. the toners all are in properly, the black toner is new and full, but the colors toners might be low, (should not be the cause for the red bar light to illuminate) the door closed, no paper jammed in the track. so can spencer D, or owen G. help. what do i do next, short of wasting this board came all the way from china, and the toner cartridges. tks
