    I want to know why there are white dots on paper from where the drum sparks in canon ir advance 8295. What is difference between machines which gets white dots vs machines which have black dots from where the drum sparks?

    Dear Phil
    For digital machines like canon ir 3245, ir 7095 have black dots while canon ir advance 8295 have white dots. I wanted to know what is difference between the two. Both the machines are digital machines.

    I just answered this in your other thread. Basically, the drum is damaged from lack of proper service. The primary corona wires (as well as the other corona wires) need to be replaced at regular intervals. If they're not, you can get black "pepper spots". If you still don't replace them, the primary coronas will arc to the drum damaging the surface of it permanently. Those drums are very expensive, which is why it's cheaper to have your machine cleaned and the charge wires replaced regularly.

    The 82xx series has white dots if the drum is damaged.
    Depending on what technology the laser uses. There are two options.
    Where the laser writes, the toner sticks. With other technology where the laser writes toner is not applied, there are white dots on the drum when the corona damages the drum.

    If it ain't broke, don't fix it

    The Drum cleaning function really does work in the Maintenance area. I have one at around 500k. Very Nice drum and I rebuilt the engine. CLC Drum blade because its better than 8295 Blade / Transfer/ New Developer and new Corona assemblys. During a PM I noticed some intermittant smudge. Ran drum cleaning and it was then all gone.

    ok, it is very simple.
    If OPC is damaged and if graund is exposed(aluminum) then dot will be black. If OPC is just a dirty, then dots will be white. White you can clean but black one never.
