Kyocera Taskalfa 3051Ci

[gazolo]

Hello!

2 of our taskalfa 3051ci has the same problems, but with different colors. (see on pic.)
We tried chaning developer, hovewer the problem came back after 1 month.
The charge roller is fine.
Connections are fine, no dust at all on them. Drums are fine also, aswell as transfer belt.

This has to do something with the developer, but replacing is not solving it, since the machine breaks the new developer too.

Anyone seen this problem before?

We've had this before but on the colours.

Replacing drum, dev & transfer unit made no difference.

After replacing HV2 & the clean or replace HV1 terminal contacts fault was resolved.

Dev unit spacer rollers are worn. Later dev units used a white nylon roller that didn’t wear.
Replace dev with new.

I've seen this as well on various Kyocera's. I've solved it with new drum. I also put conductive grease on the drum shaft. I was told by my supervisor that it's probably bad ground on the main charge and replacement of the drum fixes it. I've swapped out main charges too, and it didn't work.

Most times I have seen that specific pattern it was the main charge roller. Interesting hearing about the worn developer issue, I'll need to start checking for that.

It's split developer spacers. When the developing roller gets too close to the drum it arcs, sometimes damaging the drum. The new style units have the spacers from the higher speed units. Replacing the developing unit will stop the arcing, but you may find that there are residual patterns on the drum from arcing. =^..^=

I got bad news for you partner! that problem is bad developer units. i have seen this problem and repaired 1 machine with used,but low count color pcdu/mc assy's. the other one, which was on 7/20/2020 was repaired with a ma kit 8305B. part number 1702LKoun1. i am absolutely sure of this repair. I'll let you faint over the cost
