OKI C9800 CYAN TONER SENSOR ERROR

SOURCE: OKI 9800 with "342" error code

problem might be with toner recycle coil which runs around the back of the belt unit. as the cyan unit is the furthest down the line if any blockages occur it can back up and lift the drum unit up. check the square opening of the recycle unit on the cyan end. Make sure you change waste toner unit when prompted or you might break a gear (big job) Karl Oki engineer

On the base of machine after removing drums and transport, there are 4 sets of 3 pins that connect to left hand bottom of each drum, these can get toner on them and not make proper contact, each set of 3 pins just pop out with the help of a flat blade, out of base to be cleaned. in yout case just switch the set under the cyan with another lot from different colour.

I am taking it that you are using genuinne non imported oki drum and toner. If this doesnt fix your problem then you must have fauly drum/toner

Hi i have the solucion a error of sensor black oki c3100. For two times i have the problem and a long time study the problem. it´s the solucion. Because i spanish the solution is in spanish languaje.
Desmontar la tapa semitransparente redonda del lateral.
El sensor lleva un iman incorporado que dice a la impresora cuando el toner se a agotado. El polvo de impresion lleva impurezas o las ponen a proposito y hacen que el iman no pueda levantar la leva que hace contanto con el sensor. Con un destornillador limpiar las impurezas que estan pegadas al iman por dentro del toner. Cerrar y listo. YA FUNCIONA JAJAJAJAJAJAJAJA.

Did you remove the plastic tape from the new cartridge?
