Consumables Question about KM c280

[Guest]

I just purchased a used Konica Minolta Bizhub c280 with a total meter reading of 84,687 (46,075 BW 38,612 color). Looking at the consumables page inside the web connection interface it shows the fusing unit, image transfer belt and roller around 33%-15%. Does that sound correct since most of those units have a life of 300,000 or more? Example the fuser has 15% but I see it should have a life around 523,000 so I would expect to see something like 60-70% left.

Other than that so far I am happy with the unit.

Thanks

Re: Consumables Question about KM c280

Yield is based on minutes of running time, not actual number of images, and here's why:

Let's say you typically print 10000 pages at a time. At 28ppm that's:
357 minutes run time + 30 second run up + 30 seconds run down = 358 minutes = 0.0358 minutes/page

Now let's say you typically print 2 pages at a time. At 28ppm that's:
0.07 minutes + 30 seconds run up + +30 seconds run down = 1.07 minutes = 0.535 minutes/page

So here's the spectrum: for let's say a total of 100,000 prints it could take anywhere from 3580 minutes to 53500 minutes, depending on how many prints you're doing at a time. Clearly that a pretty wide range. The wear on the components start the microsecond run-up start to the microsecond run-down ends. You should be seeing the point about now. Obviously the components are going to last longer if you can do the 100k in 3580 minutes rather than 53500 minutes. So how will the manufacturer figure out how the components will last based on your specific usage? They figure the life of the consumables based on minutes, whether it's minutes printing, or minutes running up/down, it's all the same (wear).

Now, in real life nobody does all continuous runs of 10k prints, and nobody does all 2 print runs. So the actual number of copies will vary, to get the actual yield in minutes. If you print off the consumables page you'll see a number in the right column, that's minutes. Does that make sense? =^..^=

Wow, I never knew that. Makes a lot of sense. One question is the column that list the minutes is that minutes remaining or minutes used. Currently my Drum Unit for Cyan is 3141M and Black is 5900M.

Thank you for the very detailed post.

Re: Consumables Question about KM c280

The number you see listed is minutes used. Each component has three flagged values: Warn, Life, and Stop
Warn is a warning on the screen
Life is recommended replacement
Stop is no further copies can be made until replaced

Waste Bottle: Life 45K (actual prints, self detects)
Drums: Warn 5676, Life 6244, Stop 6811
Black Developing Unit: Life 600K, Stop 600K
Color Developing Units: Life 120K, Stop 123K
Ozone Filter, Primary Transfer, Secondary Transfer: Warn 20008, Life 22008, Stop 24009
Bypass Rollers, Tray #3 Rollers: Life 300K (actual prints)
Fuser: Life 550K, Stop 580K
DF Rollers: Life 200K (actual originals)

Some of these units are chipped, and self reset. Others require a Life value reset. See your manual for details. =^..^=
