Konica ineo 227 - stained outprints

[Shakur]

Hello everyone,
I have a KM 227 mono, after 110k outprints it started to make problems with outprints quality.
Changed develop and drum, it helped for 2 weeks, then same problem.
Anyone got ideas? SKMBT_C28022051310120.pdfSKMBT_C28022051310121.pdf

You replaced OEM developing unit and drum, whole complete units?
What kind of toner used, OEM or some replacement?

That's dev loss - either the compatible parts are crap or the air ducts and toner filter is stuffed with dev/toner. A lack of ventilation can cause this. Somethimes HV issues can also lead to dev loss. It's not necessary the HV board - sometimes it's charge leakage from a bad drum/corona/charge roller/contacts.

Doesn't this unit have a complete image unit with drum+dev? How come the dev is original but the drum is regenerated?

Drum+dev is not stick togheter. I ordered OEM dev and regenerated drum by myself, thaths how it comes. Thanks for reply, so ill try to clean it up, otherwise maybe replace HV is the way...

Re: Konica ineo 227 - stained outprints

I suspect toner is making problem and maybe drum too and developer is propably contaminated.
Have few 227 with 600-700k and never had any problem but i use OEM toner and OEM drums.
I only replacing developing units on machines where user puts some other toner than OEM.
In this combination drum can last easy about 200k prints without any output quality problem.

Ps:when you rebuild drum did you use chip to reset drum life or not?

Yes, i did, chip is new
.
I tried other drum (not OEM), other toner (not OEM) and nothing changed, still same problems, so firstly i aim at HV, dunno.

Most likely your developing unit is dead due to not using OEM toner. We have encounter similar issue from user using aftermarket toner causing dotted & lighter output.


At the end, We billed the user a new developer unit, OEM toner and service charge to clean the hopper unit as well.

Had plenty of trouble with compatible toner. In all the cases I had the machine always over toned. Have not seen it causing depleted developer.
