check you developer lifespan ...

The code references an abnormal low toner density in the black IU.

Check the toner bottle to ensure that it is feeding toner into the sub hopper unit under the bottle. Sometimes users will insert the bottle incorrectly and not lock it properly in place...the lever on the front of the toner hopper for that bottle is moved down to the left to remove and insert the bottle. When moved to the upper position, it both locks the bottle in place and opens a cover on the bottom of the bottle.

It is possible the toner hopper itself is not functioning as well. Either the motor drive is not working, that is, broken, or there is a problem with the printer control board that it is connected to. This is a rare problem and not very likely.

Also, it is possible the image unit itself is defective...the sensor could be at fault...or its not pushed in correctly to make an electrical connection.

Try searching the forum and you will find the code usually happens if a drum or dev count has been reset without actually replacement. You also have to do the clearance of the counters before closing the rh door.
Always search the forum before asking for assistance, as often the fix has been posted before.

This code will occur if you relplace the drum unit w/o replacing the developer. Emujo

Ooops...disregard my last...I somehow thought the machine was a C250....different beast all together.

This is another case of all the techs guessing because the poster did not think any extra info was needed, like a meter count and when , if ever the drum was changed. If you are a user, call a tech.

From an end user or an untrained tech in a 3rd world country this would be understandable and forgivable but you're right FixTheCopier, some of our "professional" colleagues...........
