Would be helpful if pdf sample was shown but it sounds like plastic drive coupling

You mean the one that drives the dev. Unit? I will post the sample picture if i'll be back at costumers office.the yellow totaly gone. Even i try to print on single color yellow 0% appear but sometimes it goes back.

Its on the back of the machine look behind drums on rear frame you will see 8 drive couplings 4 x silver and 4x white

Smiley of course it's in the machine side. Remember you swaped developer units.
Sometimes it will drive, sometimes not, at the end drive will fail ultimately. Not seen in Canon, but I guess they are all the same.

If the dev couplings are good(machine and housing), check the drum dev drive assembly. The bushing gets oval shaped and you lose color intermittently. Sometimes logs E24 if I remember...pain in the butt to change this assembly color off.pdf

In my same case the protective flap on the laser did not open. Check it out.

Re: Ir advc 5235 missing yellow color

Good day guy i went to client today. Check the laser shutter i try do remove it so that it will totaly open but still yellow color didnot appear. I try single color to check if the drum and developer rotate i swap the drum with one who have dots and i appears it means that the drum and developer rotate. Icheck those coupling at they look good and they rotate without any grinding noise or sound. So im thinking maybe the issue is on the laser unit. I will try to swap it next time and update you guys on the result.

Definitely...Swap the black/cyan laser unit with the yellow/magenta...same laser assemblies. If deletion changes to black or cyan, it's the laser

Re: Ir advc 5235 missing yellow color

Thanks canuck i will try it and update the result.
