    So place an original in the glass and make 20 copies. When it is done do it again.

    Do this procedure a few times and check if speed is slowing down.

    Than put heavy paper (heavy 2 at least) and run it for 50 or more. Would the symptom appear ?
    Machine is still at customer place.I can't try this now.
    This week we will replace it with another one, then we'll be able to make a detailed analysis.
    As i remember symptom start accuring after 25 copies or prints.
    Consequent batches of 20 should work ok because device has a time to heat up fixing unit again.
    I will let you knoow when i try ...

    It sounds like the down sequence is cutting in too much...plain paper shouldn't be taking that much heat away from the fuser. The speed shouldn't drop that much based on plain paper.

    See the info below
    They use only A4 plain paper and we checked few time paper type in machine.
    Yes, i agree... According to the manual it shouldn't drop so much with plain paper.

    unless I misunderstood him, I think he meant driver settings for the customer that is printing.

    if the driver is set to paper type heavy 2 for example the machine will behave as if heavy 2 is in the tray even if it is plain.

    double check the driver settings.

    I didn't check driver setting. I will at next visit.
    But the same problem appearing with copiing too ...not just with print.

    Re: IRA8295 slowing down during printing

    basically what you need to do is:

    put some plain paper on stack bypass and register it as heavy 2.

    Than make copies from the stack bypass - (no need for printing).

    All of these (and the 20 batches test) are mostly to specify if error happens due to DC or not.

    If machine runs heavy 2 in the speed it should run without drops in speed - it will mean that mechanically everything is fine.

    I would try heavy 3 and some other kind just to be sure...

    ah fair enough. I'd check the spooling settings too while I was there and make sure the computer is doing the heavy lifting rather than sending the job for the printer to do the spooling, that can cause slow printing too.

    have you flashed the firmware? i.e. ran a full replace rather than just an update? it could be worth doing if for nothing else than to rule it out as a cause of the problem.

    I'd also double check the tray settings in the machine if you haven't already done so, I've had it in the past where users go fiddling with the individual tray settings in the machine and wonder why it stops working properly

    Re: IRA8295 slowing down during printing

    Hi,

    It sems that we solved the problem...
    Funniest thing is that we're not sure what was the problem ...

    When we unplugged the finisher from the main unit, machine sudenlly start to work normally.
    Without temperature drops and without slowing down the speed...

    After 500 copies we plugged in the finisher again and gues what , machine still working properly!!!

    We have to guarantee to the customer that it will work so if
    someone have a logical explanation I'd be grateful.

    I'm still thinking that some of main PCB's have some issue. DC or Main Controller ...


    And thanks for all your previous suggestions ...

    Re: IRA8295 slowing down during printing

    Rule number 1 that I have learned from working on Canons...turn it off...unplug it from the wall for a couple of minutes then plug it back in and turn it on. Years ago I went on a call escalation identical to this but it was an IRC3200 with external finisher. Tech replaced all sorts of boards and stuff. He turned it off to service it, but did not unplug it. I unplugged and rebooted, and there you go

    Thanks for the tip ... those are the moments when I become nostalgic for analog machines.
