F26-1 is a L detect error for the dev. It could be a few things. First try a new dev and run l detect in 36 mode. If the error is still there try a TDS sensor. I have also have had the toner hopper not rotating also cause this code so chech that toner is being added. You can do this in 47 mode 01

If you need further instuctions on how to do this let me know

TDS sensor failed. replace the TDS sensor and developer and don't forget to run l-detect.
