The part what have you searching for is developer housing p.n.604K24226, and you need a fresh developer material, depends on colour 604K18020 Yellow, 604K17990 Magenta, 604K17960 Cyan.
Off course you need a tech to replace them.
Good Afternoon. I have a part that I need to replace on my Docucolor 242 Digital Printer. Problem is, I don't know what the part is, apologies in advance for my lack of knowledge. I included two photos. Here's a brief description. I had to replace a color drum. When I pulled out the color drum on the right side, the part that permanently stays in the drawer right next to the drum has a rubber part or a brush type part that looks like it was damaged. It looks like something that maybe gets worn. Thank you in advance, the photo I posted shows the drawer with the color drum out, that photo is of the part still in the drawer and the damaged area on that part.
