[C390] Auto-toner sensor-C abnormality (Cyan)
<Color toner low density>
When you check the printing status to find out that the color printing ratio isless than 5%, color toner low density might be the cause.
Turn the code 08-2692 "Prevention of color toner low density / ON/OFF setting" to ON, and then set number of sheets to be judged at the code 08-2693 "Prevention of color toner low density / Judged number of sheets setting".

If the color printing ratio is 5% or more, check the following.
(1) Is the developer unit installed properly?
(2) Check if the connector CN340 on the LGC board isdisconnected from the auto toner sensor or the harnesses are open circuited. Correct if necessary.
(3) Check if there is any foreign matter such as toner in the drawer connector of the equipment and fuser unit or the connector of the auto toner sensor. Remove if there is and reconnect it.
(4) Service or replace the auto-toner sensor.

Bizhub c6500 c2454

Black developing unit fault, has the black developer been replaced? Was it replaced correctly, with required counters cleared and proper test run after install? Was who ever installed new developer using a vacuum cleaner? If so might have destroyed the sensor located below the developer unit. (NEVER EVER USE A VACUUM CLEANER TO REMOVE DEVELOPER STATIC ELECTRICTY can destroy the ATDC (Automatic Toner Density Control) sensor. Toner mixes with the developer, on any Developer unit. So could have a bad sensor or control board. As for the counters if the developer was replaced but counters not properly cleared then copier thinks the developer is old and will adjust voltage as required when in fact new developer is installed and messing with image issues. KONICAMINOLTA PRODUCTION PRINT MACHINES USE THOSE COUNTERS!!!!!!!!!

This could be a DC controller issue or and issue with the black drum unit. If you have replaced the Black Drum, and it still produces the same error after doing a print, then you will need to replace the DC controller PCB and possibly look at the power supply.

Instead of Bule print DC12 prints Violet

Hi there! The blue color is becoming violet because the Cyan and the Magenta toners are not getting mixed in the proper 100:100 ratio (100% Magenta and 100% Cyan make CMYK Blue). Since the print is violet, the culprit is the Cyan toner. Now, first, get the Cyan Developer Assy checked if there is enough developer in it. If no, get it refilled by a proper tech and manually mix about 50 grams of the Cyan Toner with the developer. Also get the tech to check the trimmer gap on the Developer Assy with a metering gauge. If yes, next check the Cyan dispenser motor located on the backside of the Toner Housing Assy. It is probably broken and not dispensing any toner to the Cyan Developer Assy . Additionally, check for the Cyan Dispenser Auger blockage or jam. It is located under the Cyan Toner Cartridge in the Toner Housing Assy and also check the auger under the Cyan Developer Assy. After sorting these out, you should get proper CMYK blue from the 10th or 12th page once you resume printing.Let me know. Regards

I'm using Goldwell 12BG which says 2+1 on the box. Is the formula 2 oz. of developer/peroxide to1 oz. of toner or is it 2 oz. of toner to 1 oz. of developer/peroxide and should I use 20% or 30%...

Ratio is always developer to color, so a 2:1 is 2 parts developer to 1 part color. Example mixture is 40 ml developer to 20 ml color.

30 vol gives you better control and less damage to your hair. If you have VERY dark hair (level 5/4 or below), you need to pre-lift and then apply the color. It sounds like you're not a trained stylist, so I don't recommend 40 vol as it lifts too fast for most people to get an even application, especially if you're applying it to your own head (since it takes longer to do generally speaking).

You can work in sections to preserve color and get a more even application. Simply mix enough color for one section at at time, apply and process, then rinse ONLY that section with water to stop the chemical process. Repeat on all other sections. Good luck!

Our sharp MX-3100n printer is "offline" and shows code "VC" - how do I get it back online?

Apparently your machine is set to stop when the supply counters trigger a maintenance code. You can type # * C * and go into Sim 26-38 and bypass this.

VC means your cyan developer has reached its' rated life of 60,000 copies and needs to be changed. Your yellow and magenta developer which are usually changed at the same time as the cyan have also reached their end of life (VM, VY) and so all 3 will need to be changed (not black, your VK code will come up at 100,000).

You will need the color developer kit and the seals and filter. Sim 24 resets the counters and sim 25 resets the toner-developer mix ratio (this is MANDATORY or your new developer will be ruined, you must run the copier with a door open and only close it when you are ready to set the mix).

There's also various color calibrations after this you can get from a service manual. DO NOT run old developer through your machine, it will eventually lose its' magnetic properties and be carried through the copier sandblasting everything in its' path.
