Re: i-Series noisy exit rollers

So this is exactly what we all need to see here. Informative and helpful. Not bitching techs reputation.

I have come across six of these I-series the past couple months with the exact same problem. The noise varies a little but the fix is the same. Five of them were new machines that exhibited the noise a week or two after install. Last machine was installed back in 2020 and only has 110k on it but the problem showed up last week. So far the models are a mix of bw & color and range from 250i to 650i. Make a copy or print a demo page and listen closely after the sheet comes out, the noise will continue for 10-20 seconds.

Same problem here. Exit rollers on both color and B&W, and many of the B&W machines lately have had squeaky waste boxes. New machines, freshly unboxed.

Maybe because these machines sat in warehouses or on ships for long periods of time when you couldn't get machines last year.....

I've also had this noise from exit idler rollers on "4" & "8" series but only after a few years of being used.

Re: i-Series noisy exit rollers

Had one that the customer had for 2 weeks squeaking. Turned out to be the black drum unit on the back side.

Re: i-Series noisy exit rollers

Like I've posted on this forum before, really sad that Kon/Min is turning out crap with their new models!

If you go by the 3 strikes and you are out rule:

1st Strike, toner shortage!

2nd Strike, waiting months for "i" series models to be delivered!

3rd Strike, new machines having issues right out of the box!

What's next? How much do they expect dealers & end users to put up with. Canon & Kyocera are starting to look a lot better.....

I know of one Pro-Tech dealership that had been with Kon/Min for over 40 years that dropped dealership and went with Canon instead. My friend is service manager and said Canon's are working well. They are also Kyocera & HP XL wide format dealers.

I'm not sure any manufacturer latest and greatest model is exactly what's claimed probably not.
As long it's Japanese it should be something that you can sell to your clients.
Then we've got toner and machine shortage and KM response was really bad but imho it really depends on price as quality nowadays isn't what most of people are demanding. I would love to maintain KM brand machines but nothing against other brands too.

I hear you brother. I'm sure all OEM's have their troubles. Don't get me wrong Kon/Min is my favorite brand but most of my machines are 4 & 8 series. I'm hanging in with these older models as long as I can. Have only sold a few "i" series.
In all fairness to Kon/Min I've serviced all brands in the 40+ years in this business and Kon/Min has been the best OEM by far! This is what makes it so sad to see them go down hill...

Re: i-Series noisy exit rollers

I performed this same fix on a C-360i just last week.. great information though, and thanks for posting it! I didn't know where the squeak was coming from, so I ended up taking the exit section out to find it. Good to know you can lube it without taking it out.

And, yes, the machine shortage is over, and I'm not having as much trouble getting toner, but what a LOUSY thing to do to your loyal dealers. A company with the breadth and scope of KM should have sent out numerous updates to their dealers, throughout the fiasco. But alas, the Japanese are just too proud...

Agree about the Japs. Funny how they will not admit to a problem until they have a solution for it.

Re: i-Series noisy exit rollers

I have had multiple i series machines with the squeaky exit rollers. The lube fix is a winner for sure. Watch out for the plastic gears on the waster toner and waster transfer boxes. In fact, now whenever I work on one of these machines I apply lubrication to all these components as a matter of course.

Re: i-Series noisy exit rollers

Can confirm that i had some C300i with this problem, but i had more noisy exit rollers on C3350i or 4050i.
I don't know if it was already posted on other threads, but related to noises, we had a C250i with noise during paper pick up on trays, turns out that konica modified a holder on the paper feed section (AA2J563104).

What sort of noise was this coming from pickup holder? Iv got one with a squealing noise lower down in the machine, rear side, inline with bypass tray, and cannot pinpoint where its coming from.

Re: i-Series noisy exit rollers

Had a C450i with a noisy exit - ran it whilst pushing down the lower exit rollers, so that they weren't turning - the squeak stopped, stripped down the exit unit completely, cleaned and lubed everything - the noise went, came back a week later. put another exit unit in - the problem went away, for about 2 weeks. Again, pushed down the lower exit rollers, and squeaking stopped. removed the 18/28T gear p/no AA7N2313000 and ran the device, the squeaking stopped, so cleaned the shaft and inside the gear, and lubed both - the squeak went - for 2 weeks

So as a last resort, I'd run out of ideas, i ordered the fuser drive unit, which also drives the exit unit . it's been in for 8 weeks now - and no squeaking
