Black is not Fusing sometimes. The First pic is the test chart with only black and is just fine. The Next one is B&W test chart copied in full color. The next pic is toner curve B&W and the next is the color test chart copied in color. (You can see where Black is not fusing) I reset factory defaults. I changed fuser and the heater. The toner that is in the machine is the OEM I sold them.Just when I think I have these machines figured out then this occures. Thanks so much for any help !!

Re: TA 5551ci Black not fusing when copying w/ other colors
Doug, probably just a media type setting. I don't know what gsm weight paper you are using, but if it is anything above 20lb (76 gsm) then it should be set for "Normal 3" I believe it is for whatever paper type you have set. If you are running it as plain paper, then go into the media setting and set "Plain" for "Normal 3". If the paper is heavier than 106 gsm then you will need to set it to an even higher setting. -

"OEM toner you just sold them"
Any idea what was in their previously? The dev unit can still be contaminated with old bad toner.Comment

Re: TA 5551ci Black not fusing when copying w/ other colors
The reason that you see it on composite black is because to can have considerably more toner than 100% fill when black is composed of four colors.
Don't just look at what media type is selected. On Kyoceras each media type can be individually changed hotter or colder, so if somebody has been fiddling with it, it could be set to anything.

1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: TA 5551ci Black not fusing when copying w/ other colors
So it's not the black toner... lol. I should have known that. I had this issue on another 3550ci and it was the settings then. (You pointed me in the right direction). I set to factory default. Thinking that will not set the paper type settings. I guess not... I am missing something here because at one point I set plain to Normal 3 and I thought that fixed it. Pretty sure it is in the settings but not sure why I can't get it to stay fixed... Thanks again for your help !!!Last edited by Doug James; 04-09-2020, 10:37 PM.Comment

Re: TA 5551ci Black not fusing when copying w/ other colors
Blackcat is correct. It's usually the larger areas that are process black that don't get fused. It's essentially 400% coverage. You can run it as thick, if it needs to be duplexed or cardstock. Anything to get it to run slower than rated speed for 20# will usually resolve it.Comment
