We had someone put a B/W belt in a color. Is this possible?

Thank you but we have tried different transfer belts and tested then in a different machine.

sometimes we added spacers to transfer connect pwb to get better contact.

check conducts of transfer belt also clean if there is toner and have leakage

Re: 4552ci with a constant C1950 transfer belt

I had three cases on Alphard's:

The first was a bent pin on the union connector where the transfer belt connects.

The second was a poorly attached transfer belt connector.

The third was harder to track: the connector from the Main PWB to the back of the union connector through the frame was partially pulled out. I suspect the harness had been moved, and consequently was not quite long enough to reach. I clipped some wire ties to gain some length in the harness. The harness there is only about a meter long, but takes a lot of twists and turns. It's not so easy to tell which way it was supposed to go. =^..^=

Re: 4552ci with a constant C1950 transfer belt

I agree with you BC
Several times bent pin A1 or B1 from connector mounted in the rear frame, poorly attached connector and the third reason is also well known.
But now we are talking about Iris instead of Alphard..
There we have had bent pin from transfer connect pwb, broken transfer connect pwb, broken feed image pwb, broken Eeprom from belt because of assembling by plugged in power plug.
Additional i received crazy information from one dealer:
System shows C1950, got new belt and C1950 was gone, now they mounted the old/ broken belt to other system and it worked without c-call.
They tried same procedure with other "C1950 belts" and a few pieces worked again.
But i can`t duplicate this solution up to yet.....

Re: 4552ci with a constant C1950 transfer belt

Just to add to the discussion. This is the one time I ran into a bent pin. I had to replace the connector that's mounted @ rear from. It was a bitch.


Notes:

Problem: Error Code C2790 after pulling and reinserting primary transfer belt.


Solution: Found bent pin @ transfer belt connector @ rear frame. Replace connector to correct.

Notes:

I had a similar prob pulled the connector but the wires came out first ��. I'm much more gentle now... You do get to play mission Impossible with the copier guessing which order the wires went..

Slightly different but I had a belt motor problem which I just packed out behind the little board so it came forward slightly.

Make sure belt easily goes in and out smoothly had the rails bent slightly that would cause the transfer belt not go in easily.

Re: 4552ci with a constant C1950 transfer belt

We have a lot of experience with this problem.The main problem is in the connector in the body of the machine.KYOCERA chose to install it loosely so that it would fit into the connector on the transfer belt unit.Following the vibrations, the solder of the connector breaks off.In most cases this happens when you come to the machine to change a transfer belt.Before the replacement, there is no problem, but after the replacement, even if we return the old transfer belt, the problem is not eliminated.U904 U906 also does not release the fault.
The solution in all the cases we had was to replace the connector in the machine.

In the meantime, C1950 is turning into nightmare.
After installing a maintenance kit on Iris 2, the system showed C1950.
Also other new belts did not work, always C1950
After first removing ALL connectors on the feed image pwb and then installing an unused belt, the system boots without C1950.

System shutdown>power plug removed>belt removed>all plugs on feed image disconnected>new belt installed>all plugs on feed image reconnected>power plug connected>system start up without C1950

Then this belt had to be removed again because there was a problem with the drive of a drum.
At the next reboot C1950 appeared again.
Even after mounting unused belt together with a new feed image pwb, the C1950 remained.

After reinstalling the original feed image pwb, the system started without error message.

What happens when the belt is removed again, I don't know, because we didn't try it.
The system was already 1 week out of order and the end customer accordingly angry.

During the C1950 was visible on the screen we created logfile by shortcut and U964 files would stored on USB key to let KDC analyze the data.

Now I am looking forward to the result.....

What i learned up to now:
You can`t use previously used in this system belts to solve C1950, it must be a unused/ new belt.
All the belts are working well in other systems!!

Re: 4552ci with a constant C1950 transfer belt

What I have seen is the transfer belt connector goes over the top of the machine side connector when you slide it in. belt rails common

Remove the connector out of the old transfer belt, and plug in only the connecter pwb to the machine and see if the serial number shows.
This would tell you if you have a mating problem or not.
