CS 2550 toner problem

[vstar]

Hi everyone, first time posting on your site.
I have been fighting a Copystar 2550 for a while now and I need some help.
It will not add toner, I have tried the Engne pcb, DV unit and another motor. You can manually run the motor by grounding it but it will not turn on by the machine. You can rnu sim130 and it goes all the way than comes up NG, but turn off and on and it goes to ready (but blank copies).
Does anyone have a hint for me on this thing. It is driving us up the wall.

Thanks for any help.

P.S. It is the correct toner

Stupid question.... Does the toner cartridge open when you install it?

[vstar]

Yes the cartridge does open, I wondered about that also at first, but the motor does'nt turn on.

hi, i don't have a schematic on the 2550, but i do have one on the 2050. if they are wired similarily, you might want to check the connection from the tcs(toner container sensor) to the drawer PCB. if you are not getting a toner empty or "add toner" light, i'm thinking that might be worth checking. on the 2050, the signal goes from the tcs to yc4, pins 1,2,3 on the drawer pcb, then from yc1, pins 6,7,8 on the drawer pcb to yc8, pins 10, 11, and 12 on the engine pcb. good luck on this one. a very unusual prob on these m/c's.

hth,
ray

Nothing has worked so far, and I am thinking that I have a bad Engine PCB (it was repaired supposidly). Does anyone know of a company that can repair these? Hytech and Ambasador do not at this time. They do not have a machine to test it on.

At this point your only option is Kyocera Mita. Engine PCB about $100.00 Main about $550.00. Thats repair price..

Mita board repair

Hey Kyoceradude, Can you give me the address for mita board repair?
Our company split and we can't find the address anywhere.
Thanks

2550 toner problem

Under the main high voltage pcb is a small motor that is for toner replenising. Ther is a small worm gear on the motor shaft that wears down only for a couple of teeth at the gear that drives the toner . If this is the case the dv unit comes up as ng when 130 is run. Good Luck

It seems i have same problem.I find a fuse on 24v on hvtpcb but the toner motor has no command(24v) . Any suggestions?
thanks

Could you possibly have installed a Kyocera/Mita toner cartridge in a Copystar? The toner is the same, but the drive coupler is different. It doesn't mate, so you could run U130 forever and get no toner.

If it is the correct toner cartridge, make sure that:

A) the door opens when the cartridge is inserted.
B) the spring loaded drive coupler is truely spring loaded. Sometimes the bore of the coupler binds up, and doesn't spring back when the cartridge is inserted.
C) the cartridge has not been exposed to excessive heat. It could have been sitting on the radiator and is now a fused block of toner, not a cartridge of powder.

I don't doubt you veracity about the motor not turning. Its just very unusual, and it doesn't matter what the toner sensor reads, U130 should still force feed toner.

Back again

On hvt pcb on kyocera 2550 found ip301 (n38) burned and R335 (hv-10A 500mn) seems interrupted. I replaced n38 but i don't know what is r335 (fuse,resistor). But for the momment, the copy is copmplitly black.
The toner motor still doesn't work. I will apreciate any suggestion.
Thanks!

Last time I saw this happen it the MC shorting. Sounds like you have a few things going on and treating each symptom individually isn't working. How about try a new HVT PCB (from your previous post it may be toast) and engine PCB; a fresh full PM and new motor. Make sure you are getting a good drum gnd and trans roller gnd.

If I think of anything else I'll post it. Good luck!

cs 2550 toner problem

I just had a problem when I instaled a new dev unit. I ran 130 it completed NG did not appear, but the dev unit was empty. I found that the connector at yc27 on the engine pcb was not seated. Connector yc27 is where the toner empty signal is. This connector tells the toner motor to turn on. pg 2-3-14 in the service manual shows the pin out. Hope this helps.

we had this problem here but I don't know if you believe, we got a bad toner cartridge, we encounter it in the same lot number of the toner cartridge
