To buy the fix you need this data

Model(correctly a model is indicated on the corps of printer, but not in a report!),
Serial Number (Número de série);
CRUM (chip cartridge);
Firmware Version.

This infirmation can be found the printing: Configuration Report and Supplies Information Report.

-Press ? on panel
-Touch System Configuration or Supplies
-Touch Print

If you cannot print the report, the data is verified through remote access. If the toner is on a chip or does not work, an additional $7 will be charged to generate the reset without CRUM (without the toner chip).

I received the files, now what?

First, prepare the printer to receive the file: With the printer off, hold down the button: [//] Yellow it and hold down the [Moon] button at the same time, after ~ 2 seconds, release both. When you successfully enter the forced mode, a message will appear on the screen {Firmware Download Mode}. The compacted file sent contains: "FIX...", "usbprns2" and INSTRUCTIONS. With the printer  in the way described above, just drag FIX to usbprn2

After this procedure in a few minutes the printer will restart. Remove the toner chip and try printing without a chip. From that moment on, do not use a chip in the toner anymore.

ATTENTION!!!After successfully reprogramming the printer, remove the chip from the cartridge and store it somewhere safe (the chip). In all the cartridges that you are going to use in the printer, the chip must be removed or seal. If you accidentally inserted a new cartridge without removing the chip, the device will be blocked.  To unlock it, do the reset using the same chip..
