Preventive measure of Image Unit in CLP-300/CLX-2160

The color Samsung printers often need maintenance. You can see the short summary in this article. Removing the block unit. In order to do this you need to pull the detent handle.

(Figure 1)

It looks like it

(Figure 2)

Starting its disassembly:

1. Unbolt the bolt

2. Take out the waste ink absorber

(Figure 3)

Unbolt the screw circled in red circle

(Figure 4)

1. Avert out the worm to the blue arrow direction

2. Then in the red arrow direction.

(Figure 5)

We take out the guide path on the left side from the slot (it is circled in blue), where we remove the screw (Figure 4) in the direction of the red arrow. At the same time we try not to drag it too heavily, you can broke it.

(Figure 6)

Once you removed the guide path from the slot (the screw from the right side and the guide path from the left) push the drum in the arrow direction while holding the IU with one hand, until it engages. 

Lift the right side of the block and then put aside the left guide path.

(Figure 7)

IU disassembled into two parts. We are interested in the toner unit of each color (4 pieces). The photo shows the uneven of toner on Develop Roller.

(Figure 8)

The toner block are easily pulled out. Take it from the both sides and pull on.

(Figure 9)

You need to disassemble the toner block of each color and clean it.

(Figure 10)

Unbolt the screws (5 pieces) which holding the top cover (circled in red circle).

(Figure 11)

Remove the cover

(Figure 12)

Remove the toner waste from the hopper and cover. The dispenser is soldered directly to the cove of the block, so clean it very carefully, trying not deform the dispenser.

(Figure 13)

Carefully cleans the oxide spots from the dispenser, it is best to do with the nail to prevent damage.

Wetting a waste with the alcohol and wipe the dispenser.

(Figure 14)

Now remove the Develop roller to wash it. Unbolt the three screws from the right side of the toner block.

(Figure 15)

Remove the side cover.

(Figure 16)

Remove the remote roller and the snap ring.

(Figure 17)

Remove the Develop Roller, clean it with any solvent. After that rinse it out and dry it. Important note: don't wipe it with a dry cloth, it will lead to the stripes and scratches which will be visible in the image.

You need to this with all toners block.

After the Develop Roller dry out set it in its place. We pour the toner into the hopper and fasten the cover back. When you installing the upper cover (the dispenser), seals that are on each side of the dispenser must be on the top of it, otherwise the toner will pour.
