    developer change questions

    Hello

    Just looking at changing my developers... the machine is a 2300n done about 35k colour but they are around 3years old at a guess... how many years do they normally last? does the kits have an expiry date?? should I only buy fresh stock? or can I do an ebay buy to save money?

    thanks

    Re: developer change questions

    Personally, I'd stay with fresh developer. Five years of sitting on a shelf can render developer useless.

    You'll get the best possible developer yield printing high volumes. At low volumes you'll need to change developer more often, especially when toner density starts to vary.

    I need to back up a little. Developer is a mixture of ferrite (or starter) and toner. The proportion of ferrite to toner must stay the same within a few percent to maintain image quality. As developer fails is can become overtoned (too much toner), or undertoned (too little toner). The fix for both situations is the same. =^..^=
    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.
