Probably its a transfer problem.
Probe whith other tipe of paper, change transfer values in service mode...

If it was the drum you'd have lines, I would say replace the developer & charge corona if you can get one.

You could surely buy a complete new image unit on the internet?

do you know where can i buy developer? maybe an online store...

is it necessary charge corona? we replaced the developer just by the top side.... or is needed open entire unit to put developer inside corona?

Re: c352 unknown issue

hello, the sample just looksw like contaminated DV likely from paper dust.
you need a whole IU, you cannot vacuum any developer, its not like kyocera there are metal particles in the DV unit mixed with toner, you cannot seperate.
best you can try is running 50 or so of the halftone patterns at 255 like you provided. you will see the white spots dissapate. you will go through some toner but it may flush the contamination out enough to get by.

Re: c352 unknown issue

1. Developing unit may be doing this
2. No developer is bought separately
3. Expired or toner for use can also cause this.
