Taskalpha 3050ci Magenta shading

**anzew** · 02-22-2018

Hi all,

I am having an issue with this model here.
Machine was showing magenta shades when printing multiple pages, first page usually came out clean.
We replaced the magenta developer and drum at the same time, ran all calibrations and fault still happens.

Checked all contacts were clean, I swapped over with another drum in the machine. Ran all calibrations again and machine is printing fine, however I have a feeling it will refault.

Have a look at the sample prints, I am leaning towards a high voltage board.. Cheers

Looks like bad dev and charge unit

High Voltage Unit is a good candidate if it comes back. =^..^=

Thanks for the info, the dev and drum have been changed with new units.

Hi blackcat, would it be high voltage PWB1 or PWB2

I think it's HV#2, the big one behind the main drive. =^..^=
