Konica minolta c3320i horrible prints

[brent]

prints or copies after I did the half tone pattern and the cyan magenta and black are ok yellow has streaks. even after I just replaced the drum today. thoughts? I did a stabilizer as well hoping we could get it. yellow toner in machine as well. I have seen this a few times but a new yellow iu has always fixed this any thoughts on this?

thank you

TCR %?
VDC Table value?
Did the yellow lines change from one drum to the other?
Lead edge to trail edge or side to side?

Some of this info might help me and other help solve this problem on this lemon model. Also a picture of the image issue would help too

I have never been good at pics on a computer lol I will try.. the drums are end to end lines void areas and the new drum didnt help anything. I will try to put a pic on

If it is void lines i would look at the laser and clean the slit glass first.

Clean the laser glass if this doesn't help replace the yellow imaging unit.

I guess you are an end user & not a tech as cleaning the laser glass would be the FIRST thing to try (& free!)

There's a cleaning rod in the panel. Gray stick with a white cotton tip on it. There are slots at the bottom of each image to get access to clean without any disassembly.

How rude... but otherwise correct.

the best thing you can do with that thing is to take it outside and fuck it into the bin!
get yourself a decent A3 machine.

thank you. with these being trouble free I had not thought of that. but I appreciate the advice

Wait... trouble free ??...but how?
Even on very low meters toners have gone, IUs also. Depending on your luck they have jamming and other issues.

ok so I had a chance today to really get into the unit. merely using the cleaning rod and pad didnt clean it. I took all the units out and belt as well gave it a thorough cleaning
we are back together.. for the rude comment above. it needed to be taken apart. I had time today it is fixed thanks everyone
