Dirty or Bad Primary Charge Roller

As with most of the newer Samsung models, the error codes are all in English and are self-explanatory. The
biggest problems you will run into are paper jams, and a dirty scanner. Keeping the machine clean with
periodic maintenance will take care of most of them.
This modification is for the modification of the Samsung ML-1210 engine specifically the Lexmark
E210. This modification will allow not only all of the ML-1210 cartridges to be tested, but the SF-5100
cartridges as well!
It is very simple to modify these printers so that they accept all versions of these cartridges for
testing (Including the SF-5100). That being said, please be aware that this will almost certainly void
the warranty of the machine. Perform the following modification at your own risk.
1.
Remove the two top silver screws. The top cover will come loose. Lift up and remove the top cover.
2.
Remove the three black screws from the laser unit. Carefully flip up the laser unit so that the metal tab
is exposed.
You can see that with a total of eight slots, and the possibility of using more than one tab at a time,
Samsung has quite a few options for cartridge variations!
3.
Remove the tab screw and tab.
4.
Replace the laser unit. Make sure that the alignment tabs are in their proper location, and that the
cables are snug. Install the three screws.
5.
Install the top cover. Make sure that the back section of the cover is locked in place. Install the two
silver screws. The machine is modified! Run a few test pages to ensure all is aligned properly.
