tu problema esta en el sensor de deteccion de giro de la botella, ese sensor es el que esta a lado izquierdo por un costado arriba, haz esta prueba para que no desarmes toda la tolva, quita la tapa de enfrente y la tapa donde embona el bote del toner para que quede mas espacio, metes la mano y vas atener que hacer una manguerita como extencion de una sopladora, le echas aire a presion al sensor y listo, va a quedar limpio, luego entras a modo servicio y ajustas la funcion de tcr, te va a dar un valor, despues dentro de modo servico te vas a test y ejecutas el full image halftone y sacas unas 5o copias, con esto se va a descompensar la unidad de revelado y va a pedir toner para hacer su autoajuste, vas a ver que el bote gire, si gira ya quedo listo el equipo, si no gira, esta dañado el sensor y te va a marcar el error c-2403, debes de cambiar el sensor, te dejo mi correo, para cualqueir duda, ensamblerman@gmail.com

Este código indica que no detecta el giro de la botella de toner. Al fondo, donde encaja el cartucho de toner, está el sensor PS28, que, en ocasiones se ensucia. Otra posibilidad, me pasó hoy justamente: el receptáculo donde empata la botella tiene tres "paticas" con unas protuberancias que enganchan en la botella y la hacen mover. Esas paticas se abren, o se desgastan, y no hay giro de la botella. Solución: cambiar esa pieza, o, si no, colocar cinta aislante o de enmascarar, alrededor de esa pieza para cerrarla y hacer que agarre el frasco más fácilmente. Para llegar allá, el desarme es grande. La primera vez lo hice siguiendo paso a paso las indicaciones del manual. Escríbeme a copierclinic@yahoo.com, y te envío copia del Field service manual. Saludos desde Bogotá.

1. When an empty toner bottle is rotated while removing it from the machine, the alignment tab goes out of home position. Then, when a new bottle is
inserted, it does not rotate correctly.
A modification is available. Please refer to attached Bulletin Number 5775 and follow the procedures outlined. To view the PDF, Adobe Reader® must be
installed. Adobe Reader® can be downloaded for free from the Adobe® web site at: http://www.adobe.com/products/acrobat/readstep2.html .
Note : To reset C-2403 after replacing the toner bottle, perform the following:
a. Power OFF the main switch (SW2, inside front door).
b. Slide the toner bottle cradle and remove spent toner bottle.
c. Prepare new toner bottle per instructions and place toner bottle in the cradle (line up the two notches at the rear so the cartridge is laying level in the
cradle).
d. Turn bottle completely around and line up the arrow at the 12 o'clock position clockwise or counterclockwise and push cradle in and lock toner door.
e. The power should be re-enabled to ON while holding the Utility key; the Konica Minolta blue screen within 6 minutes, then the white screen with Trouble
Reset. Touch and OK will appear. f. Power OFF/ON and should go to Ready. This procedure may have to be redone several times.
2. Toner bottle is not turning.
Ensure that the toner bottle does not have any manufacturing defects. Also ensure that the pressure spring inside the pressure assembly (p/n 26TA-3332) is
applying sufficient pressure when locked into place.
3. Excessive pressure from the Toner Bottle Door.
Remove the pressure springs (Toner Supply Unit (TSU), item #7 - see attached) located in toner door.
4. The toner bottle position sensor (PS28) may have shifted when the drive section on the back of the machine was removed or installed. As a result, PS28
cannot detect rotation of the toner bottle.
Install a new mounting plate (p/n 50GA33161E) and stopper seal (p/n 447042481) for PS28. These parts prevent PS28 from becoming dislodged. Complete
details are in attached Bulletin Number 6078.
5. Contact between parts around the bottle guide section.
Please install the Toner supply auxiliary cover countermeasure as explained in the attached Parts Modification Notice.
6. If toner bottle is not installed correctly and the customer forces it then it may cause tearing of the drive tabs on the toner bottle. This will cause the bottle
not find the home position generating this error.
Please ensure that the toner bottle is inserted correctly. Refer to Bulletin 5471 for details on a modification to the toner guide assembly
7. Even though the correct procedure was used per Bulletin Number 5471 , there still may be burrson theflange tips at neck of the toner bottle.Also,PS4
and PS28 may not be sensing properly.
Verify the correct operation of PS4 and PS28. Check for burrson theflange tips at neck of the toner bottle. Use Scotch-Brite™ to remove the burrs on the
toner bottle.
Note : The service documentation does not include a procedure for checking PS4 (Toner Bottle Sensor) and the PS28 (Toner Bottle Position Sensor). To
check:
a. Enter the State Confirm mode=>'Service Mode screen'; press [State Confirmation].
b.'State Confirmation screen'; press [Sensor check].
c. 'Sensor Check screen'; press [Check Code] and, when entering the sensor check code in 3-digit format through the copy count setting button, a state
(ON/OFF) or value is displayed in the Result area.
d. For the multi-mode, press [Multi Code] and enter a three-digit multi-code through the copy count setting key. When conducting the sensor check of other
signal sources, repeat stepscand d.
IMPORTANT : Code 57, multi-mode 2, which is not listed in the bizhub 420/500 Service Manual, is used to monitor the output signals ofPS4 (Toner Bottle
Sensor), and multi-mode 3 for monitoring the output signal ofPS28 (Toner Bottle Position Sensor). These sensors are located at the rear of the hopper
assembly at the 11 o’clock position forPS28 and at the 12 o’clock position forPS4. The state of these sensors will switch from 0 to 1 if the bottle is moved
8. Excessive toner misting due to openings in Toner supply holding main body (p/n 26NA32311E).
Clean the partthoroughly with alcohol.Applya coveringlike electrical tape to cover the openings as shown in the attached file.
CAUTION Very Happyo not cover the opening from which the toner is added to the developer.
