C454e HELP PLEASE

[PieterShaun]

Good day people..

I came here in desperate need for help please.

I stay in a small town in SA, nearest agent that can help me is 250km from me.

I am having trouble with my machine.

I did replace 2 new drums yesterday, and this is how my colors look. It prints greenish etc on normal prints.

I tried to do a gradation, but upon stabilizing is shows Stabilize NG. Then in Utility mode, Stabilize could not be done there is an error state.
Machine shows no error.

I did clean glass, cleaned TB, and I did clean sensors.

Here is pictures attached for full tone and half tone test. I cannot see why I cannot do gradation.

All levels for dev units are above 6.75%

Would really appreciate all the help I can get.

Are the drums original? Which ones did you change? Start testing with the yellow one, swap the drum with the cyan one and test to see if the effect changes color if it is not the development unit.

Looking at your print examples you have some depleted developer in the colour units.

I suspect that this machine is not genuine Konica Minolta toner too.

Thanks for the reply man..

Yep I Use generic as for Minolta is far form me, and the pricing is ridiculous. And they are always stock shorted.

In service mode it says dev unit are above 67%? Can it be that is low, pardon my Question. Appreciate all the help I can get. My main problem that bothers me, is why Cant I do an gradation...

cant calibrate if it cant make solid colors without the zebra stripes.
its really that simple.
replace the DV units and hope for the best with inferior toner.
ive never had a DV unit recover after the diag stripes appear.

Thanks for the input, appreciate it. Will start replacing the 2 and so forth... Thanks again.

Bro, your developer units are well consumed with non OEM toner. The developer levels are low. If you want to go for compatible parts do use CET products that are of good enough quality.

You will be surprised.
Just recently we recovered 2 depleted color 8 series DV units by adding developer from other used ones.
Bird page was awful mess before, washed out and faded with nasty stripes and then voila...like new machine again

use a scale when doing this ,refill to known full weight. run a bunch of solids, see if units maintain toner levels. reset and stabilize, run gradation.

ya know what, i need to apologize, its been a really really long time (think analogs) since i had to McGuyver DV levels to get a good image.
i have always worked for dealers that only deal with OEM parts and supplies. ive been spoiled by the ability to order anything i ever needed for a machine and have forgotten about indy dealers that dont have a multimillion dollar company that lets them "try" new parts just to see if it fixes it and able to absorb the cost without making a dent.
i think ive become an elitist prick that just wouldnt have the confidence to use aftermarket supplies since konica would never support their use.
i need to remember to try on other peoples shoes once in a while.

A Humble man is the wisest of all because they "have seen a thing or two" but sometimes we forget our hard struggles from the past.

You are a wise man.

And he really is. Amen to that brother 👏

I actually worked for said multi million dollar company, but if i could do it faster for free by improvising, well you know.

If you have some old developer units laying around you can 'top up' the depleted units with a funnel or as I do roll up some paper to make one.
