MX-3050N no yellow

[bigdaddyooo]

Drum is coated with yellow toner when doing a 64-1 pattern 9. I have no transfer from drum to TC1. I have replaced MFP pwb, PCU pwb, TC pwb and TC1 unit. Still having the issue. I swapped Y and M drums, still have no yellow. Any ideas?

1. Do a CN update, this fixes alot of goofy issues for me.
2. Try a different working y-dev unit. And check the connections on the rear of machine that contact the t1 belt unit, especially around
the y lift area.
Good luck.

Does it work on copy mode? i had something similar where as print was missing a channel and copy was ok. Sim 67-17 sorted this for me, odd one.

Re: MX-3050N no yellow UPDATE

I started getting 1/2 yellow from top to bottom so for shits and giggles I replaced the LSU unit and VIOLA....fixed. Thank you guys for the suggestions
