# Imprimante Ricoh SP C252DN
Cet article couvre deux opérations sur la Ricoh SP C252DN sous Linux : l'installation du fichier PPD pour exploiter toutes les fonctionnalités de l'imprimante, et la reprogrammation des puces de toner pour réinitialiser les niveaux d'encre.
## Installation du fichier PPD sous Linux
Un fichier PPD (PostScript Printer Description) décrit les capacités d'une imprimante : résolutions disponibles, options de finition, polices intégrées, etc. Les systèmes Linux s'appuient sur ce descripteur pour exposer les options d'impression avancées au système et aux applications.
### 1. Ajouter l'imprimante via JetDirect
Lors de l'ajout de l'imprimante, sélectionner le protocole **JetDirect**.
![Sélection du protocole JetDirect](20230313-201028.png)
### 2. Choisir un pilote générique temporaire
Choisir `Generic` > `Generic PDF Printer`. Ce pilote servira de base avant l'installation du PPD spécifique.

### 3. Télécharger le PPD Ricoh
Télécharger le fichier **PPD** depuis le dépôt suivant :
[https://git.abonnel.fr/cedricAbonnel/richo_c250dn_c252dn/src/branch/main/ppd](https://git.abonnel.fr/cedricAbonnel/richo_c250dn_c252dn/src/branch/main/ppd)
### 4. Installer le PPD
Dans la liste des imprimantes, ouvrir l'imprimante nouvellement ajoutée, cliquer sur l'icône `Paramètres` (![roue crantée](20230313-202024.png)) puis sur `Informations sur l'imprimante`.
![Informations sur l'imprimante](20230313-201543.png)
Cliquer sur `Installer le fichier PPD`, sélectionner le fichier téléchargé, ajuster le nom et l'emplacement si besoin.

Fermer la fenêtre avec la croix.

### 5. Vérifier les options d'impression
L'imprimante apparaît désormais avec ses options avancées dans la boîte de dialogue d'impression de n'importe quelle application.

## Reprogrammation de la puce de toner
Les cartouches de toner Ricoh Aficio SP C250SF / SP C250DN / C250e / C252DN intègrent une puce EEPROM qui signale les niveaux d'encre au firmware. Reprogrammer cette puce permet de réinitialiser ces niveaux après un rechargement physique du toner.
### Matériel et port de communication
L'opération se fait via un Arduino communiquant en I²C avec la puce. Les images ci-dessous montrent le port de communication de la cartouche et le câblage à réaliser.

### Code Arduino
Adapter la valeur de `EEPROM_I2C_ADDRESS` selon la couleur de la puce à reprogrammer :
- `83` — noir (K)
- `82` — cyan (C)
- `81` — magenta (M)
- `80` — jaune (Y)
```cpp
// This code updates Ricoh toner chips for Ricoh Aficio SP C250SF, SP C250DN, C250e, etc.
// Update EEPROM_I2C_ADDRESS to the chip you want to reprogram:
// 83 = K (black), 82 = C (cyan), 81 = M (magenta), 80 = Y (yellow)
#define EEPROM_I2C_ADDRESS 83
#include <Wire.h>
// Blank data for K, C, M and Y chips (128 bytes each), dumped from replacement chips.
