Nashuatec MP 2500SP Toner Empty troubleshooting Procedure

In this article we will discuss the Nashuatec MP 2500SP Toner Empty troubleshooting issue, how the toner supply unit works, what goes wrong and how to go about fixing it.

Explanation of how the Nashuatec MP 2500SP Toner Supply Unit Works

When a toner bottle is located in the bottle holder unit (A) and the item is placed in completely, toner shutter (B) relocates against the side (C) of the PCU. Once the toner bottle holder handle (D) is put back in the previous location, the cap (E) on the toner bottle is drawn away and saved in place by the chuck (F).

The toner supply system carries toner out from the tube to the development unit. The toner bottle posesses a spiral pattern (G) which assists to advance toner to the development unit.

Whenever the toner bottle holder is released, the chuck releases the toner bottle cap to its appropriate placement to prevent toner from dispersing.

As soon as the bottle holder unit is brought out to add a new toner bottle, the toner shutter shuts to close the opening as a result of pressure from a spring.

    Possible cause of the Nashuatec MP 2500SP add toner message

    1. Empty toner cartridge
    2. Defective toner – (Toner that has gotten moisture in it can clump and not work through the supply unit.)
    3. Defective toner supply unit
    4. Defective toner clutch
    5. Defective developer unit or sensor.
    Those are probably the 5 most popular causes but, off course, with any problem, there is always more things that can come up.

    Probably the easiest and most inexpensive solution past the toner cartridge may possibly be the toner supply unit. Whenever you reverse the toner lock lever the supply unit removes the cap on the toner. As the toner spins, the toner ovals downward into the supply unit within the developer unit.

    Two specific things sometimes happen here. To begin with, the toner supply unit can neglect to set the lid back over the toner cartridge. This may lead to a mess during the time you remove the old toner. Then, when you place the new toner in, the prior lid remains and does not take out the cap from the new toner. The second situation is when the clamp, (F) in the picture, will not open completely around the pull off tab in the middle of the toner cover. Therefore, you’re thinking the toner is locked in and therefore the cap is off even though the cap always stays on.

    To troubleshoot you will have to take out the toner supply unit and the cover from the toner. This might be dirty so it’s best to have an area ready to put everything down which can easily be cleaned. Of course, the first thing to do is check inside the main area of the toner supply unit. Ensure that the cover still isn’t located within it. The next step is to take out the cap from the toner. Then, find out if the clamp will grab the cover and take it into position. If it won’t, occasionally you can bump in a little on the lock lever and it will enlarge the clamp enough to slip over the lid. If that does happen, then you can take it all apart and clean everything out to see if will begin opening all the way up or you can typically, just switch the supply unit.
