Canon C1 - How to increase toner density

[mynameis]

Hey everybody.

I am trying to get a higher toner density (as high as possible) on my Canon C1+.
I have already modified the 2nd transfer voltage of one paper type i have duplicated, which has a little impact.

Are there some parameters i can modify in the service mode?
What about ADJUST>DENS> Should i try to modify the SGNL, P-SGNL and REF values? If so, are higher values giving me higher toner density on the print?

Should i modify the gap of the doctor blade in the developers? If i open it further than standard, will i get more toner applied?

Any other ideas?


Thanks in advance...

There's a mode that you can change which enables you to change the method to control the amount of toner

Press [Additional Functions].
Press [System Settings].
Press [Device Management Settings].
Press [Density Adjustment Mode].
Press [B Mode].
Press [OK].

A Mode
This is the default setting. The amount of toner is restricted in this mode, and settings made for colour adjustments, such as Color Balance, may not be reflected to prevent the toner on the paper from scattering and image blurring on high density areas.


B Mode
This mode removes all toner restrictions. Settings made for colour adjustments, such as Color Balance, are directly reflected.

Thanks hidius!

So i tried that, but it is not what i am looking for.

It does increase the toner ammounts in the mid- and light areas of the picture, but it is not giving me a higher density in the 100% C/M/Y or K.
That's why i assume i have to manipulate somewhere in the service mode, or even on the hardware-side like the doctor blade...?

Parts all good? Devs,drums,itb,transfer rolls,etc. You don't go messing with blade gap,signal values,etc.. on one of these....what media are you using? Is it in specs for the machine? Something else is wrong...settings,parts,etc. Messing with blade gaps and stuff....you're fudging a defective machine...You're gonna mess it up then need to restart all devs,etc.....

Parts are all good.
The thing is: I use this machine as a ceramic printer, it is converted to ceramic toner. After printing on decal paper, the toner gets transfered onto ceramic substrates, such as mugs, tableware etc...then being fired at high temp.

The print quality is fine, i just try to get more overall toner density, so my fired result could be even more brilliant. I used to work with the CLC 1100 series which, compared to the C1, printed a much higher density.

Setting up new developers and changing spare parts are no problem..


Changing the REF values for example must have an impact on the density, right? I just don't know in which direction to tweak, or if there are other methods to increase the density...

Hello mynameis,
did you succeed in increasing toner density?
I have C1 with ceramic toners too and would like to increase density of Magenta red toner a bit...
C, Y, K give more than sufficient density, Magenta Red is slightly lighter than I want it to be.
Thans for any idea to anybody.
