Black toner stopped printing in the middle of a document.

SOURCE: Oki C3530 MFP

Con el cartucho instalado en su posición, tiramos de él para arriba y sacamos todo el alojamiento del mismo. En la parte derecha del mismo hay un cuadradito con una ventanilla de plástico que debe estar totalmente liberada. El problema es que ésta a veces se queda medio tapada y el sensor no detecta el cartucho. Levantar ese plástico hacia arriba todo lo que se pueda ( con algo que tenga punta, un boli por ejemplo) y volver a poner todo el alojamiento en su sitio. Suele funcionar a la primera, y si no, apagar y encender de nuevo la impresora.

Your indication regarding the 100% does not necessarily indicate a damaged chip (sensor).
Many chips do not work by actually sensing the toner but by usage or other tricks.
We cannot be sure about what happened but replacing the drum and affected items
should solve the problem. Needed parts may be found at

Hi

Thanks for using FixYa. Toner sensor error is related to the agitator inside the toner cartridge, it occasionally falls out of its housing so it does not move the toner sensor which is the white plastic piece that moves up and down on the coloured handle, the toner sensors themselves see this white flag if it doesn’t move then the printer thinks the sensor is broken so toner sensor error is flagged and if the flag moves too quickly the machine thinks the toner is empty. To resolve the issue your printer is facing with please check that toner lock lever is in position and follow the following procedure---

Press the cover release and open the printer’s top cover fully. Make sure the Toner Cartridge in question is correctly positioned and the right hand clip is pushed back. While holding it by its top centre, lift the image drum, complete with its toner cartridge, up and out of the printer. On the Right hand side of the toner look for a sensor patch, make sure this is not dirty. If it is dirty clean it with a soft object such as cotton wool. Now look inside the printer opposite to where the sensor patch would sit. There is a black square with a sensor located inside and check that this is not dirty. Now replace the drum and toner, and close the printer cover. Try to print a test page and it will start printing normally.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

THIS SOLUTION IS FOR AN OKI C3400N ONLY

As I'm sure you know, that blinking amber light indicates that:

1. A toner lock is not fully "locked", or
2. A toner is empty, or
3. A drum is empty or near empty

1. Make sure the toner "lock" on all toners is fully engaged - assuming they are

1. Open the top
2. Lift out the entire black assemble including the toner and drum components.
3. Keeping the assembly in the same orientation as you lifted it out, look on the RIGHT end.
4. You should see two metal contact points, near the top at about the same level as the top of the toner.
5. Just below these contact, you should see a small, rectangular hole - about 1/4" square.
6. If you look in there you may see what looks like a small piece of black plastic that covers the hole from inside.
7. If so, take a small pointed object (like a bent paper-clip) and gently reach in the hole and touch the small plastic piece on the inside that is covering the hole.
8. You should be able to gently lift that piece of plastic UP.
9. You may have to try lifting it a time or two, but it should stay UP if you have a new black toner installed.
10. Once you have it UP carefully reinstall the assembly.
11. Close the top and let the printer recycle.
12. You may need to try this a couple of times to get the plastic to stay up on your new toner.
