A way to decrease density of toner?

[fishleg]

I see this a lot with Kyocera they seem to have a really high density of toner so it ends up wrapping in the fuser or will double image on really solid halftones.

I know you can calibrate etc but is there anything in service mode where you can say to the machine ok that's the target density but I want say 10% less so calibrate to that.

Probably a silly question but I see it a lot in schools where they use a really solid green or red. I usually just pop the lead edge up and calibrate the machine and hope it lasts. They seem to have the density a bit too high. I could put eco mode on but that's a bit extreme I wanted kind of a middle ground between eco and normal.

Thanks for any help.

There is probably a SIM mode to have it calibrate less often. There is also toner saver mode than will reduce density.

Using OEM toner you should not be getting double imaging

Shouldn't but you do. I went to one where the black was really dense and the machine seemed to have lost its marbles did a u140 calib and recalibrated everything and it was fine after. That one was a one off I'm more talking about really dense halftones that cause fuser wraps. The manuals are really poor at describing the service modes.

The machine are great but I'm forever going to fuser wraps from really dense half tones. Must be a way to say ok calibrate on the light side please.

Check under system default user side for a setting

Is there a setting that effects everything so printing and copying?

Re: A way to decrease density of toner?

Do you have a specific model in mind?

You might try:
U485: selecting a different color table
U429: color density adjustments

Try U464/ Target
Decrease value and you get more solid
Increase value and you get less solid
After next calibration you can check if it works

are they using 'turd party' toners?

Genuine toners, seeing it at every school I go to pretty much if I'm really unlucky the teachers will have took chunks out the upper rollers.

I'm doing calibrations etc so maybe that fixes it but it's mad to see the same thing daily pretty much. It's very hard to replicate as I wasn't there to see it jam but when I take the jam out it's always solid halftones causing it to wrap.

I'll try the u464 and u429 next one I see. Wish the service manual was a bit easier to read u464 is very hard to understand what it actually does. Is u464 messing with laser power or mag charge?

Fairly new to Kyoceras so I'm learning something every machine I see pretty much.

are they prints or copies?

copies require at least 3/8" white border at top of the page to keep from sticking/wrapping on the fuser roller... standard industry standards.

this comes from not properly placing copies on the platen glass.

Re: A way to decrease density of toner?

Just a question on their paper is it a name brand and weight?

Kyocera don't usually have that kind of issues.

Interesting. I'm gonna have that out for myself. Thanks for the information.

Yeah that's what I do increase void edge and it does seem to help. I'm not sure if it's just the machine starts going out of whack over time if it's not calibrated but I've seen it on a lot of machines now 4052 5053 3235 mainly. I've seen from people just having a really solid block in the middle of the page it's less likely but I've seen it wrap from that. For me I just think they really start to over tone towards 200k if not serviced/calibrated.

Sorry, but i made a big mistake
to make image density darker you has to increase the value
to make image density lighter you has to decrease the value
On older Venus series we used this setting (+20)to decrease the edge reduction problem.
But you also can use it to decrease the thickness of black.
Try to change U464/ Target for toner layer BK from 140 to 120, run U464/ calibration, U410/ Halftone adjustment and check the result.

Additional way will be Prescribe command if "D4" present. (Not available on all systems)
Initial value = "3"
Send command !R! FRPO D4,2 ;EXIT;

Going back to the paper any paper that wraps around the fuser i look at the paper being used especially if its recycled paper.
