I replaced the magenta dv unit and recalibrated.
prints and copies both have magenta distortions.
I am trying a primary belt next, anybody have a
Taskalfa 5053ci with images like these samples?

What's the page count on the DV's and DR's?


If I had to guess from the examples that you posted, I'd say it's a magenta drum cleaning problem.

Also, you need to run some solid test patterns. See below:

drums swapping changed nothing

If it were the transfer belit, I'd expect to see more than one color affected.

Look like something badly with magenta developer unit - magenta drum unit combo. Why you changed M developer unit, what was your initial problem?

It sure looks like bad developer spacers to me.

Was it a new unused developing unit? Or a unit of unknown provenance? It sure does not look like a new magenta developing unit to me. =^..^=

I believe you but how did you determine this? It looks different than the bad spacers on my example that you pointed out. Thanks.

The way I understand it, when the spacers wear, the distance between the developing roller and the drum diminishes, and starts arcing. =^..^=

I fixed it by reconnecting and cleaning all high voltage connections.
