you have to hit start, it prints a 4 color page and THEN gives a live reading. :)

do you see a good brush (DV particles standing on end) on the mag rollers?
is the toner path clear? can you boot in safe mode and run manual toner add?
could just be a bad ATDC sensor on the IU.

Try a system error reset first.

Thanks, brush and path toner are good,there are toner in cartridge, but I can not add toner in service mode,start buttom lights red,I See call service and yellow, magenta,cyan and black have several error codes, maybe can be a electronic card. How can I reset this code?

If you have a problem in a yellow UI you canīt reset the code , this code reset with the front door and exit again when the machine start to make image adjustment . Try with another yellow UI to do a test .

You can't fix an IU by doing an error clear. If it is defective, it needs to be replaced. I know they are expensive, but that is the risk of being in the copier repair business.
