    IRC3220

    Does anyone know what the numbers for drum life under display/misc relate too? I'm wondering if they are the life percentage used. This machine shows no drum life left and 2 drums under misc are at around 295 while the other 2 are around 395. It popped an e00020 for the yellow drum today. I'm wondering if the other numbers are a better guage.

    I thought it was a % of drum life. 0% when new and 100% used, but 295 and 395??
    If you are getting an E020 I'd replace the drum unit. I just use the drum life as a rough estimate, I really go by test page 10. If it don't jam in the fuser you know your fuser is good. Then I look for any weak density. If the drum life used up but the color is solid I leave the drum in. If a color is weak but only 1/2 life I replace it. Just how I do it though for what its worth.

    The number is a percent and is based on drum rotations. The number under display/misc is calculated differently depending on the version of DCON. v35.01 and later show higher numbers than lower versions of DCON do. They last usually into the 200 and 300 percent range but will vary greatly depending on how the machine is used. Ive seen the k pcu make over 600% but its a mess by then. Many also fail in 100% range. Almost always e020s require a pcu to be replaced.

    Thanks for the replies guys. I plan on replacing the drums. Just wondering how those numbers worked.

    To add to the already answered question, the drawback to letting your drums run REAL long is that they tend to get pretty dirty around the ITB, causing slipping and color registration issues. I tend to let mine "soak" till they create copy quality issues, and then ususally I replace them as a set. You can replace one at a time as needed, but that creates extra service visits, and degraded customer confidence in the machine...

    It's usually Cyan and Magenta drums that affect the colour quality...not so much the yellow so I tend to let the yellow go until it begins to dump...but if I go to a machine and my test chart copy looks craptacular then I'll run single colour test charts to determine the quality of each drum and replace if needed.
    iRC3200 drums are hard to pick exactly when they'll start dumping...iRC4080 drums ALWAYS begin to dump at 200% so we have a policy in place that if you attend a machine and the drum counts are at or near 200% then we swap out the drums.

    the drum life is canon cheat it use to be drum rotation when those figures did'nt fit they changed it to dev roller(smaller ie more) - however completey pointless as based on very small coverage ie @5% - best start point do pg 10 test pf it will show straight away ......
