Remanufacturing the HP LaserJet Pro M255 W206A,X series Black and Color Toner cartridges

By Mike Josiah and the Technical Staff at Uninet

First released in December 2019 the M255 series of color laser printers are based on a 21ppm black & color, 600 Dpi engine. (3600 with ImageRET)

The first page out is stated at under 10.5 seconds. Standard installed memory for the M255 series is 128 or 256MB depending on the model.

New cartridges do not come with a drum cover. They use a plastic box insert to protect the cartridge. It’s a good idea to have your customers save these inserts. See Figure 1 The starter cartridges that ship with the printer are rated for 700 pages CMY and 800 pages K.

The end caps are plastic welded, and the DB has a left-hand threaded screw, but once past the welds are not that difficult to do.

3) Slide the screwdriver inside the end cap to the place indicated and gently pry again until the end cap comes free. See Figure 4

Figure 4

4) Remove the end cap See Figure 5

Figure 5

5) Remove the drum from the cartridge. Doing this now will make separating the two halves easier See Figure 6

Figure 6

6) Start to separate the two halves. You will see a small black plastic tab on the drum gear Assembly that blocks you from removing the waste chamber. Press down opposite the tab while pulling the end cap out to separate the two halves. See Figures 7 & 8

Figure 7

7) Remove the PCR. Clean with your preferred PCR cleaner and place aside in a clean area. See Figure 9

Figure 9

8) Remove the two wiper blade screws and the wiper blade. See Figure 10
