machine first show warming up, when the customer send his first job in the moornig, for long time and cmr try to power off the machine after waiting aprox 30 min.

then he power on the machine and the c-c101 appeared.

we found icp-23 on prcb and we replace it but problem remains.

1. what can be the cause of that error
2. how can we resolve without replacing prcb

same problem have occured to another cmr and when we replace prcb icp-23 blow out again. that's why we do not want to replace prcb first.

thanks in advance

here is some info about this:
C-C101 after performing PM.
Solution:

PROBABLE CAUSES:
1. When the sub power switch (SW2) is ON, no response is received from the Printer Control Board (PRCB) within the specified time because ICP23 on PRCB is OPEN. Too long of a screw was used in installing transfer unit. The screw has come in contact with drum and shorted the drum potential sensor, which in turn has opened ICP23.
Check installation of transfer units. Replace the incorrect screw with a shorter one, replace damaged DRPS (p/n A03U R736 00) and the PRCB (p/n A03U R759 00).

2. Transfer drive motor M18 has failed, connector was not seated properly, or connector and/or wiring from PRCB to motor has been damaged.
Check connections and wiring from PRCB to M18. Replace the PRCB (p/n A03U R759 00) and also M18 if necessary (p/n 27LA 8001 2E).

thanks for reply but error came out without PM. this article is already read.

first thing in the morning was showing warming up for about 30 minutes and cmr try to power-off and power-on the machine. after that error came up...

C-C101 ICP23 o/c because of short in 5V circuit.

I had this problem after a Tech had replaced a drum for 2214 and then m/c came up with C-C101, It took me about 3 Hrs to find the problem it was the purple wiring loom at the back of the process carriage (the Temp/humidity sensor) got trapped on the locating shaft hole. One of the wires sheath got chaffed and bare wire in contact with the frame and so 5V going to ground.

Hope this helps

This should be possible to find if you search the forum. I had a machine down for a month due to this fault. The black plastic guide that the transfer unit rests in is so close to the ratchet that holds the wire cowl on the back of the transfer section. Knock it when your mounting the transfer unit....and the wire will crawl up and get cut and cause a short. Pictures here show where this happens. (Note that in one picture the entire transfer unit has been removed from the machine)

We glued the pin in, and keep an eye on this spot on our other machines.

Yeah thats it watch out for that one.....

A C-C101 and o/c ICP23 is 5v supply to Printer control board.... if you look at the ROM version the Printer Control will be blank ie. dead board.

I think I must have been lucky to catch that one in the same day if you had the machine down for a month.



Do you have any answers for C67-08 first thing in the morning? But once the machine warms up you can switch it on and off and it will not fault until next morning?

DEAR
thanks to reply but i hav been check my machine by replacing prcb from other machine its work mean there is no problume with machine only board faulty. and i have checked all icp specialy icp23 its ok but this board still not work so can u help me, is it possible to run this board.i already upgrade latest firmware.

You got it !
that's the problem.

I thing KM must fix this spot because can drive easily to PRCB problems.

thanks a lot and be carefull when closing proccess unit !

check this spot and wires there for your safety.

also check all icp to PRCB, maybe something else is shortcircuit.

Had this problem and thought I should share the solution in my case. Machine is a C6500.

In the end C-C101 is really a 5 volt short problem that causes the power supplies not to start. The pictures above of the rear of the carriage unit are one place the short can occur (and those wires will get loose there if you look at them crooked) but of course any pinched wire will do the same. Good diagnostic for the carriage is to start the machine with the carriage pulled out. If there is a short in there the machine should start normally (if the boards aren't already fried) as the short is disconnected.

In my case the probem was a blown index sensor in the yellow write unit laser!

Customer reported the machine was running normally but just shut down with the C101 code and that was the end. By checking the indicator LED's on the Printer Control board and Image Processor board with a working unit we could see that 5 volts was missing. Got confused because we replaced just the printer control which promptly blew out again without any visible positive result. Next time by we did the Printer control and the Image Processor board at the same time with known good parts taken from another machine. Machine lit up but promptly gave C-4714 for the yellow write unit index sensor. Shut the thing off fast (which saved the printer board but not the IP) and based on some experience with shorts and lasers from way back at the start of C6500's, replaced all four write units, another printer board and another IP board.

Replacing all the lasers may seem like overkill but the last time I experienced a laser short chain of events it turned out that a single shorted laser had ruined all four lasers and the printer control board, VERY expensive fix. Multiple lasers here was a response to that bad day.

Also replaced the wire bundle running from the lasers to the Image Processing board as it appeared physically chewed up (but a lot of them do).

Observations:
Soldered on fuses are an expensive service result for a cheap engineering solution
Wish I knew more about the indicator LED's on the Printer and Image board (admit I have not yet checked on this forum for that info)
Best diagnostic move for this problem in this case was replacing Printer and Image board at the same time with known good parts (only power up after both boards are installed). Doing it one at a time just blew up the new board with no indication that anything changed.

Got a call from one of my Techs today!! He was had a white line and cleaned the laser path switched on the machine and it threw C-C101. He phoned me and and told me what happened... I knew straight away what happened... trapped wire at back of process unit.

Lucky I had a PRCB in the car and met up with him onsite.... it give me a chance to take some good photos of the problem.
