Kyocera FS4020DN won't add ink

I just replaced the drum and developer in my Kyocera FS4020DN and put in a new toner cartridge. It says "Original toner installed" and won't add ink - copies are blank.

SOURCE: Kyocera 1810 drum replacement

If you have some mechanical skills and a steady hand you can change the drum. However it worth the money to pay a "pro"to do it. Also you may want to replace the cleaning blade too.

1. Open the front cover - where the toner is.
2. Remove the black cover - 2 screws
3. Remove a little stopper at the bottom of the drum unit + 1 screw
4. Disconnect the drum unit cable.
5. Take off 2 screws which secure the Drum Unit.
6. On top of the Drum unit you should see 2 white plastic stoppers - front and back side ends - You have to push them inside to keep the cleanng blade away from the drum.
7. Remove the MCH assembley - 1 screw.
8. Remove the front separation claws + plate - 2 screws.
9. Remove the Drum Shaft
10. Replace the Drum

There are few details about how to manipulate a Drum - Do not touch the surface, do not expose it to intense light...

SOURCE: i already replace a new toner but there an error msg AP

Hi 
The AP message indicates thet the dev is so low in toner that the machine has to go into a full cycle mode to get the toner levels up.
The error code is telling you that one cycle is not enough. you will have to turn the copier off/on and cycle it at least one more time....more if neccessary

SOURCE: my kyocera km 1500, it says

E33 means the copier is out of toner. Try tuning off and let it cycle a few times, if you ran it completely out some times it takes a few cycles to get running again.

Use only the specified parts to replace the thermal cutout. Never substitute electric wires, as the printer may be seriously

When removing the hook of the connector, be sure to release the hook.

Take care not to get the wire caught.

We have a Kyocera Mita KM 1510 and I am getting an error code C710 and the add toner light is on. I put in a new toner cartridge but the error message and the light are still on. Any suggestions?


C 710 is a Toner Sensor Problem

Defective toner sensor - Replace toner sensor

Poor contact of the toner sensor connector terminals - Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace cable.

Developer problem - Replace developer.

7410 is an error (all numbers following : is the number of pages printed.

If you open the door on the left hand side of the printer, where your waste toner container goes and press firmly on the drum which is located behind the waste toner container and close the printer backup. If the drum is properly seated the error should close.

Kyocera FS-3900DN Ecosys Call Service 2200:0100998 Help please our printer has stopped working


The Call Service 2200 is a drum motor error. The motor or gears might need to be replaced. First remove and re-seat both the developer and the drum unit. The developer is directly under the toner cartridge - lift it up then out first, then open left side door remove the waste bin and press the button on the drum unit just above the waste bin pull the unit out (carefull not to touch the drum surface). Re-seat both units. If this does not work call in a Kyocera Tech.
