can you buy just the document processor for a CS255 ?

[djwhoo]

cs 255 clutch does not engage. do these clutches go bad? or is it the board? The service manual has no procedure how to remove the cluch. Do i Just wing it? When the document feeder door is closed the dp drive and clutches typically engage, but the clutch does not, like it should. I havent ran component control on it yet (wish i did). but do these clutches seem to go bad?

customer is will to buy another DP for the cs255 but I can not find it

Before you go replacing whole document feeders, maybe you'd like to see if you're getting 24vdc steady to the clutch, and if you're getting the ground signal to turn it on. You can meter these at the clutch's connector, or look up in the manual the pins on the DP controller. Clutch failure is certainly not very common.

I would diagnose it further, if it was me. =^..^=

Thanks Blackcat .I agree. I need to go back and do a little follow up and check the voltages.

These DPs can be rather problematic, and there are plenty of updates for them. I would suggest that you go thru all the service bulletins first.

Another test that I have done is unplug the clutch and find the connector that has 24v on it.
Plug the clutch back in and tap the signal line to frame, or use the I/O functions in service mode.
You should hear the clutch tap.
If it taps, you have a bad board. If it doesn't tap, it is a bad clutch.

Do these go bad? You bet your ass they do.
How to remove it is just tear into it and take it apart. Take many pictures with your phone to see how it was put together before you took it apart.
Assembly is the opposite of disassembly, according to all the service manuals.

cool.. yea so i couldnt find anything in the service manual that had "instructions" how to remove the clutch. Am i just not seeing it? but i can figure that out but also,

I didnt see any controller for the DP clutch in maintenance mode. but you obviously dont hear the clutch click when you cycle the DP door. I ordered the clutch but worried its the board. I will have to make time to stop back. Thanks for your time

I didnt see any controller for the DP clutch in maintenance mode... I look and its there. u203.

The clutch reference on the service manual wiring diagram is DPPFCL. It is connected to the DP Main PWB [DPMPWB] YC8 . pin 1 is singnal on/off and pin 2 is 24v.

With the above information, you can check if the clutch is functional or not. there is also a secondary feed clutch on the dp. look at the service manual carefully and take your time in locating the senors and switches ect. It seems to me you are just rushing into presumptions rather than actually doing the necessary checks.

On the dp cover there is the shaft that drives the pickup roller. examine the parts on that shaft, check for wear or damage. Also make sure the paper detect sensor is working.

Actually i am looking at the TA-255 manuals which i believe is cross reference to the cs255. hope i am correct here.

Awesome !! Thanks !!

Re: can you buy just the document processor for a CS255 ?

Ok. Upon further review. Ha. The feed/ transport section which is basically held down with 4 screws lifts off of the "platen" cover section of the dp assembly. The back of the assembly does not seat correctly though the 4 screws tighten firmly and it seems to be correct until you look at it from the side - with the door cover off . the entire assembly is higher in the back which leaves the rollers lower then the plastic paper path. On the top and on the bottom after it makes the turn to exit. I can not seem to determine the cause of why it's not seated correctly. All of the roller shafts turn but the paper is being stopped by the plastic holders of the platen/exit pinch rollers. I think that it has to be a bushing or something not seated right but it all seems to be in place. Btw. It was the clutch. Then I ran into more problems after it was fed. Thanks.

Re: can you buy just the document processor for a CS255 ?

Good news!! The exit/ duplex baffle was the culprit. The customer or someone must have disassembled the unit and reassembled it incorrectly. Which apparently isn't hard to do unless you knew that the duplex baffle needs to be fully actuated before placing the top feed assembly down onto the platen assembly. The baffle was causing the entire upper section to not seat correctly causing the rollers to not have enough "bite" to transport the paper. Thanks mntech
