bizhub c224e, wrong Toner level indicator

[occus]

Hi

I have a bizhub c224e with the message "Toner low" for cyan and yellow...
Counter: 29079 black and 378 color
FW: G20-A9 Function 3 (yes i know there is the new one C8 Function 5, but there is no info about this problem)

What can be the problem? Any ideas?

To know:
-the standby mode is deactivated, to eliminate the problem with the booklet-tray full message
-pplm all is set to not stop

Thanks

Low toner, so what fault do you have!? has the machine stopped printing?
I disable the low toner warnings to stop the customer replacing the toners too early when not needed.

Hi copier tech

No, the machine prints... yes of course i can deactivate the message but thats not the solution.
The Toner level status you can see on the display is not really nice, looking really bad for only 378 color prints.

We had a lot of problems (now more ore less fixed) but the customer thinks it is a bad machine... but i don't want change

Re: bizhub c224e, wrong Toner level indicator

These machines do not measure toner in the bottle...they measure by how many rotations from the toner bottle....basically dev asks toner hopper for toner when it's sensor reaches a certain point....sub hopper feeds dev unit and when it's sensor reaches a certain point and asks for toner from bottle...bottle spins until sub hopper is happy...if it rotates so many times it will send a message it is low on toner....changing toner bottles that are not empty can throw this balance off...it will correct itself after a few cycles...I explain this to my customers(well in simpler terms)...I tell them to not change toner bottles unless the machine asks for a new one...if they do it will throw the gauges off but will correct themselves so not to freak out...

Hi Kidaver

Thanks for support!
Yes i read the theory manual and understand how it works with the toner supply.
But i would say thats a failure or a problem... and what about the magenta toner? magenta indicator shows full... only cyan and yellow is low.

i thinks there is a bug somewhere.

You can check you VCC readings....Service Mode-State Confirmation-Level History 1-TCR....they should be between 4-6% if I remember correctly...if they are good then your I/U are good there and might look at the sensor in the sub hopper...

Thank you for your hint... now i can remember on a tech notice for bizhub c220series... change the toner hopper sensor.

Shake those toners vigorously!!!! had them pack on one end and it takes some force to get them flowing.

Re: bizhub c224e, wrong Toner level indicator

The measuring is in the hopper unit, and there have been issues with incorrect sensitivity.

Also...upgrade the firmware.

Re: bizhub c224e, wrong Toner level indicator

Also turn off the "consumable low" warning in service mode

Re: bizhub c224e, wrong Toner level indicator

This is a very poor placement of a color copier. How many times do you think that this machine has done a color calibration in 30K copies? Many times. Each time color toner is used to calibrate the color image. I doesn't matter if the last 5K images were all black, it will still do a color calibration. All your color toner has been used in calibrations.

You ask: Can't we just stop these calibrations? Sure ... if you don't care what the images look like. Because they will look like crap. Even the black images.

In the final analysis this customer does not need a color copier. =^..^=

You could change the stabilzation mode setting to "black priority". I don't know how much it will effect the color toner consumption but it might help.

i have loads of the C224e and C454e with this problem. The C242e you can just take the bottle out shake it and replace where the C454e has a chip so the toner has to be replaced.
in the latest firmware release GD3 E4 which in the read me file states that incorrect toner levels show on the control panel plus incorrect info sent too CSRC.
Once firmware has been applied to the C454e you need to relace the toners.

i hope this helps

Re: bizhub c224e, wrong Toner level indicator

yes it was a firmware bug.... of course one more on the "e" series

Do you have never problems with black priority? i remember on tech notice about this... many problems.
Instead i use the sw50 to 01 function...

No problems at all. I did on the early C224 but now i send all mine out on black priority.
