    Edit: Run sim. 25-1 and check the toner sensor reading. Somewhere in your manual it should give you the "normal range" for toner sensor for the model that you're working on.


    EDIT 2: If the toner sensor reading is out of range, the question becomes is it over or under toned and WHY?
    If it's over-toned, run a bunch of sky-shots until the the reading is in the normal range. If it's over-toned, run simulation that forcibly adds toner until you get to normal range.

    Also, are you using generic toner? It's also possible that you have a bad toner sensor. Or perhaps something is clogging the toner supply channel.

    I replaced the developer unit and developer and it fixed the F2-64.

    Remove toners and run SIM 25-2 for 15 seconds. (FYI, 25-1 is only for new dv material, not recommended for testing) The displayed values are how much toner is inside the dv unit. The higher the number the lower proportion of toner; lower number = higher proportion of toner in dv unit. These codes appears when this number is below 73 or above 230.
    Running this sim first will tell you if you have too much or too little toner in the first 30 seconds of a call like this and spare you from "chasing ghosts".


    Failing to plan is planning to fail!!!

    You actually have these reversed. 25-1 is for checking toner/dv. 25-2 is only for new dv material.

    That model is very prone to that error code... Check the lower holder for black toner motor... sometimes plastic clip breaks and motor can seperate from drive not allowing toner to be added... after developer change your usually good for 200 copies until toner is needed and the code will return.... also check to see if toner transport pipe is clogged.... do you have a build up on dv unit were toner is added, if so you have a dv unit issue.... hope this helps

    also check this out for toner transport info....MFP-TB-1477
