    OKI B2540 fuser temp error

    i have checked the thermistor and thermal fuse and have a copy of the service manual. The manual says press the down arrow, then # them T but it also say to "set the 8 bit parameter installation configuration 1 to 1" before pressing the keys. No where in this manual can I find where to set that dip switch Help please from a 20 year tech( who is a little embarrassed to ask how to fix this darn little printer).

      just heard back from OKI and the answer is... press down arrow, then * then # this will give you sos1 and sos2 , press okay, you will get eight bit binary, change left bit from 0 to 1 then ok, press red stop button. Now press down arrow, then # and finally the T button. Power down the printer then power on. Go back in and change the first bit back to 0 and you should have your printer back!

      Now why can't they put that into the service manual!
      BTW I have the service manual if anyone needs it!

          Don't beat yourself up too much. Oki writes some terrible manuals. Incomplete at best. Even when they've rebadged a Sharp, for example, they still write their own abbreviated version of the manual.

          This is good information. I'll add it into my spreadsheet for future reference. =^..^=
          If you'd like a serious answer to your request:
          1) demonstrate that you've read the manual
          2) demonstrate that you made some attempt to fix it.
          3) if you're going to ask about jams include the jam code.
          4) if you're going to ask about an error code include the error code.
          5) You are the person onsite. Only you can make observations.

                              Useful information, thanks.
                              Questions:
                              1) Is the eight bit binary you mention the sos1?
                              2) What is the T button? I have looked in the user manual and could not identify anything that fits.

                              And, please, could I get a copy of the service manual?

                              Best regards, Volker

                                  There are not many Oki b2540 posts, so I'll just ask this question here: I have a b2540 but all but one of my machines are now Windows 7 or 8, 64 bit.
                                  What can I do about a printer driver? Oki doesn't support this.

                                  tks for your input.
