This is generally what we've been seeing. It is important to clean the plastic vertical tube that sits between the dev unit and toner hopper. It's held on by 2 screws to the rear frame of the machine (above where a toner pump would be, on the old models).

If this piece isn't cleaned out, it dumps all of its toner into the new dev unit, and soon the hopper is clogged again.

The sub hopper was clean, I removed it and checked.

I recently installed a 2504ex this had a failed yellow dev unit after only about 10k.
Dev unit was replaced a few days later machine asks for yellow toner even tho bottle is full.
My last visit hopper looked fine.

Ahh yes looks like a similar issue.

what i did in total due to a few visits

new Y pcdu
new hopper due to old one faulty
cleaned the TD sensors
cleaned and checked the sub hopper
changed the toner bottle so it went to 100% full

Its strange how the toner issue goes down to nearly empty even with a nearly full bottle and the only way to get round it is to fit a new bottle, This I have done on a few machines.
