STUDIO4520C C3B1 code

[lavinius]

Hi all,

I had to empty the waste toner few days ago and after doing so everything went OK for a few days then got an error to replace black toner, done that, printed a few hundred pages then got the C3B1 error.

I haven't seen any references to it but from the looks of it the C3B0 is a paper feed error, what is this error?

The copier jams with the paper no matter from which tray I print, it goes past the fuser and it jams right after it, would appreciate any help

Cheers

G'Day mate,

C3B1 relates to Y-auto toner sensor abnormality.

Also C3B0 relates to the same sensor.

ok, i have replaced the toner with a new one and I still get this error, there was a lot of yellow toner left as I could see it through the plastic window, I followed the instruction and pushed the wand in 2-3 times and pulled the rod a few times as well, the error is still present

do i have to clean something as I can see a little yellow toner spillage, I don't have another developer here to try, could it be the developer?

If it just needs a clean can someone instruct me? gladly appreciate any help with this as with xmas coming nobody wants to come and have a look at it

Cheers

[C3B1] Auto-toner sensor-Y abnormality (lower limit)
<Color toner low density>
When you check the printing status to find out that the color printing ratio is less 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 is disconnected 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) Replace the auto-toner sensor.
(5) Replace the LGC board.

Just to let you know, You're gunna fucking hate this code if you aren't a tech.

thanks mate

the 08-2692 was at 1 so i left it at that presumably 1 is ON?

08-2693 was at 40, changed that down to 20

and the problem still persists ....you're right I hate this thing, I'm going to go buy a can of compressed air and give it a clean
anything else I can try ?

[jonezy999]

Compressed air won't do fuck all. Call a tech mate. You are gunna need one.

Mine was a yellow developer unit depleted of developer...tiger striping. Ran b/w fine...no color
