I looked online and the error means: - Toner empty sensor abnormality (BLACK) - Toner empty sensor output abnormality. I re-installed the cartridge and got the same error. I manually turned the printer off for 1 minute and the error came back. I was able to clear the error message #*C* then running simulation 16. When I re-install the cartridge, the F2-40 error comes back. Any suggestions.
Hi,
If you have reset the machine as described & then re--inserted the same toner cartridge giving you the same error code then I would suspect the CRUM chip that is installed on the toner cartridge is faulty.
If your machine is under a maintenance contract which includes the provision of toner then contact your service provider & they should replace it F.O.C. If you have purchased it yourself then contact the supplier advising them of a faulty cartridge. If you replace the toner with a new one, you must reset the machine as above before you insert the new toner.
Hope this helps.
Dave.

When the Toner Life End LED flips on, requires you to replace the cartridge,
even when there's still toner left in the cartridge. The machine
detects end of life by shining a light through from one side to the
other.
To circumvent the detection mechanism, remove the cartridge and put
a piece of masking tape over or jam a little bit of paper into the clear opening/circle on the right side
of the toner cartridge, and then pop the cartridge back in. Eventually,
you'll start seeing streaks, and then you'll know that the cartridge is
truly empty.

your printer will not operate with the 'color' cartridge missing you will have to install a color cartridge.

minolta printers work on "chips" if the chip atached to the cartridge is not original minolta you better change it.
SOURCE: Toner Sensor Error for Cyan and Toner Out for Black
First, I wouldn't worry about the "K toner out", it might finally disappear once you get rid of the Cyan problem, if indeed you replaced the black toner for a new and healthy one.
Make sure that the cyan toner cartridge is securely fitted in it's drum unit, and the "knob" that opens the toner cartridge is in fully open position. Sometimes when manipulating inside the printer the "knob" might get moved a bit.
Generally, the toner cartridge sensor is connected via the drum unit, so usually the problem is with proper seating of the drum unit and good electrical contact between the metal fields on the sides of the drum unit and contacts protruding inside the printer. Cleaning both of any residue might help.
Once I had a defective toner cartridge, that caused such problem, but it was the contact between the toner cartridge and the drum that was broken. You have to experiment a bit.
I'm pretty sure in this model it is possible to swap two units - if you swap for example cyan with magenta, and observe if the error moves from cyan to magenta or not, you can draw conclusions if the problem is with the toner/drum, or with the printer not seeing the cartridge for some reason (sensor inputs killed by static electricity for example).
Testimonial: "thanks for the feedback, it helps."

Wash it out with rubbing alcohol and let dry. Apparently there is a light sensor that will throw up this error if the bin is dirty.
