    Pro c651 toner cartridges problem

    After a correct Toner end condition (empty bottle) the m/c is accepting the new bottle (full on the panel) but for some reason after a number of copies you have again the toner end message.If you replace the toner again with a different catridge then everything is ok.
    After seeing this a couple of times and start checking i found that the problem is that for some reason after the new toner installation the toner pump clutch is "locked".Everything else is working toner supply clutch, toner motor , bottle motor except pump clutch.If you test the clutch manually with the output modes is working fine . Even you can fill the hopper mannually if you use a combination in the output modes.
    I believe the m/c is locking only the toner pump clutch for some reason, may be from the serial number of the catridge if the production date is too old.Just a guessing...
    All the toners we using are OEM and purchased from Ricoh.
    Anyone experienced this problem before

    What version firmware is on that machine? There was an issue with toner end conditions that Ricoh addressed with a firmware update. Not sure if that's what's going on with your unit but the bulletin reads :

    The “Pre Near End” Alert Message that appears on the Operation Panel tends to cause the users to replacethe toner bottler earlier than the appropriate timings, and as a result, toner could be wasted. The newfirmware will delay the display of “Pre Near End” to correspond with the “near end” alert timing

    Please update the Engine Firmware to the following version on your next service visit to version 1.66:04 or newer

    For models RICOH – PRO C651EX/PRO C751EX/PRO C751

    BULLETIN NUMBER: D074/D075/M044 – 050

    The most current engine firmware is version 1.70.04

    Re: Pro c651 toner cartridges problem

    All the firmwares are uptoday and that firmware was installed years ago to just save some toner.The problem happened in 3 different machines and with all the different colours.Something similar was happening in the old mpc 6501 series.All the values related to toner density are within the normal range but the machine for some reason refuses to add toner from the bottle to the hopper eventhough the toner end sensor reads 1.On the other hand the toner supply clutch is energised tosupply toner from the hopper to the dev unit.Pump clutch is definetely ok (from the output modes) and because when you replace the cartridge to a likeable one the it starts working.
