Remanufacturing the Samsung Xpress M3015DW 

MLT-D118S toner cartridge 

By Mike Josiah and the Technical Staff at Uninet 

The Samsung Xpress M3015 series of printers are based on a 30ppm, 600dpi engine. The first page out is 

stated to be under 8.5 seconds, and all “W” models so far come with Wi-Fi, Samsung Mobile print, Google Cloud 

Print and NFC (near-field communication) features built in. 

All machines released so far come standard with 128MB 

memory and have a duty cycle of 12,000 pages per month. There 

are two cartridges in this engine - the toner (MLT-D118S/L) and 

the drum cartridge (MLT-R116). The standard yield toner (S) is 

rated for 1,200 pages, and the high yield (L) is rated for 4,000 

pages. The drum unit is rated for 9,000 pages. 

The toner cartridges come with an orange plastic 

protector on them. It’s highly recommended that you save and 

re-use the OEM cover until aftermarket covers become available 

(see Figure 1).

STEP THREE 

On the opposite side of the cartridge, slice off the two plastic 

rivets with a Square Xacto-type blade. 

STEP FOUR 

Press in on the tab and gently pry off the end cap. 




STEP FIVE 

Remove the four gears as shown. 

STEP SIX 

Press in on the top cover tab and remove the cover. 

STEP SEVEN 

Remove the two screws on the doctor blade and remove the 

blade. 

STEP EIGHT 

Remove the two white plastic washers on both sides of the 

developer roller. 




STEP NINE 

Remove the developer roller. 

STEP TEN 

Clean out any remaining toner from the supply chamber. Be 

careful to clean developer roller seals. 

STEP ELEVEN 

Clean the remaining toner from the feed roller. 

STEP TWELVE 

Fill the cartridge with toner approved for use in 

the Samsung M3015DW series of printers. 

There is a fill plug, but it’s very difficult to 

remove without damage, so we recommend you 

fill the cartridge through the developer roller slot. 




STEP THIRTEEN 

When a seal becomes available, insert it now according to 

the seal instructions. 

NOTE: You can remove the feed roller by prying out the two black plastic bushings on each side of 

the roller. The top part of each bushing is glued to the bottom of the developer roller seals so care 

must be take not to damage the developer roller seals and to re-glue the bushing back in when reinstalling 

them (rubber cement). 

STEP FOURTEEN 

Install the doctor blade and two screws. 

STEP FIFTEEN 

Install the cleaned developer roller. 




STEP TWENTY SIXTEEN 

Install the two white developer roller washers. 

STEP SEVENTEEN 

Install the five gears in the order shown. 

STEP EIGHTEEN 

Install the gear-side cover. 




STEP TWENTY NINETEEN 

Install the top developer roller cover. 

STEP TWENTY 

Install the contact-side cover. 

STEP TWENTY-ONE 

Using a #29 drill bit, drill out the centres of all four plastic 

rivets (two on each side). 

STEP TWENTY-TWO 

Install four #8 x ¼” self-tapping screws into the four holes. 




STEP TWENTY-THREE 

To replace the chip, the handle plate must be removed. 

STEP TWENTY-FOUR 

Press in on the four (two on top, two on bottom) left tabs and 

start to pry up the cover. 

STEP TWENTY-FIVE 

Continue to gently pry up the cover, working your way 

towards the chip. The chip side of the cover is welded 

in place, so it will come free suddenly. If you pry it up 

gently, it will come off with no damage. 

STEP TWENTY-SIX 

Remove the chip holder by pressing in on the two tabs. 




STEP TWENTY-SEVEN 

On the chip holder, press in on the centre tab. Remove the 

old chip and replace with a new one. 

STEP TWENTY-EIGHT 

Install the chip holder back into the handle cover. 

STEP TWENTY-NINE

bottom areas on the cartridge, and install the handle cover. 

STEP THIRTY 

Make sure all the left side tabs lock, and that the right side 

is firmly held in place. 




STEP TWENTY THIRTY-ONE
