Need Help Oce' 360 loss of vacuum to 1 head

Background: The machine has been sitting for a few weeks un attended. I suspect the vacuum problem may have been the initial problem, but I'm not sure. The waste station filled with ink, then the white ink line dissolved and burst and the line. The line has been spliced and now the head won't hold ink.

I do not see any obvious leaks, and I am unfamiliar with the spec function of the ink delivery system on this machine. Also too I don't entirely understand the function of the Degas Module, and I question if these clog or get stuck in some way that may cut off the vacuum.

Secondary, the vacuum at the table is weak and even though the fans (or) pumps run there is 0 on the gauges.

Any insight would be much appreciated. If anyone can share a service manual and parts schematic that would be huge. We called Oce' and they declined service to us because we did not buy it from them. Great way to provide any incentive to ever purchase anything Canon.
Thank You

 

Hello all, and thank you for the suggestions!

The ink line burst on side where the carriage motor is, within that lower housing. It completely dissolved. I spiced it and i'm prepared to swap out the full line set.

The issue with the head not getting vacuum was the both of the white filters (in carriage) being clogged. The larger had a cured membrane of ink fully cutting off vacuum, and the smaller had a drop of what looked like amber in the connection tube. Once replaced the heads holding ink just fine.

Now, from sitting were having jet out issues from it not passing enough ink over time so were trying to run prints and purging, but were getting a Gantry Motion Error. After cycling it a few times we noticed two things; 1) the fault occurred in the same area of carriage travel regardless of where the gantry is (print location on table). 2) I noticed the gantry is cocking upon stopping. It seems the service end is over traveling by about 3/16" (but I can't be sure if its in one direction only or only limited to that side).

Rails are greased, and both lights stay solid green. I cannot find the encoder strips if it has them, so any advice would be appreciated.

Thank you

The machine is an XT.
Please pardon my ignorance, I am unfamiliar with this machine;

1. I don't know what the coals on the gantry engine refers to?
2. I do not see movement when sliding out maintenance drawer.
3. Gold encoder strips; I did clean those as I suspected they might be the encoders. They appear to be flawless. I did find the ground wires not fastened from the encoder pickups. I attached to the frame and have no difference.

All advice is very much appreciated!

So I checked the beast this morning and here's what I found:

• Brushes have a lot of life left; photo shows the worst one with some scoring but looks healthy otherwise.
• Encoder is clean, but it dose have what appears to be a wear mark down the center of the strip. Do the pick ups make contact, and do they often go bad? (see image)
• When I move gantry by hand, I notice some over-travel on either end depending upon the push or pull direction. In other words it does not move as a single rigid part staying on a fixed angle to the table.It's sort of floating between sideds and wandering around. I have no idea if this is normal or irregular?

Thats good to know. I checked the lights, and they remain green on full travel and back, No amber, no red. The only thing I noticed that raised question is if it's normal that the pickups are mounted so the lights are facing opposing directions is normal?

Ironically I found a brand new set of Renishaw encoder strips in the parts box we have. Looks like someone has already been through this process ahead of me. I don't think I'm swapping them out unless we know they are bad, as it seems they are not.

What are the group of components or parts that could be contributing to this condition beyond the motor brushes and encoders?

Also, since this thing has been parked for as long, I have to wonder if I'm going to have a jet out problem once online. I have no idea what level of maintenance has been conducted ahead of me and I can hardly get a jet profile to of it. So if I do end up with jet outs , ifs there a recovery mode in the programming, or something manual otherwise?


Thanks so much!

I went through several test runs yesterday to try to isolate this issue, and the more I look at it the more confusing its getting. The gantry lights never go off green, even on error code. On error I noticed when the machine began to move the gantry home, that one side began moving before the other, as if it pulled itself out of alignment (cocking) the gantry. So if the encoders are good and the brushes are good, what else could be causing the over run on one side?

This machine was moved about 1 year ago, Could the machine be out of square from the set up and what's the best way to confirm this?

I'm sorry to be so needy, but I am most great full for the help!

We're in the North East, USA. I do not have the key.
We would have hired a capable technician but there are none in our area as I am aware of. Are you traveling to the US any time soon?

I made another request to Canon and they sent out a tech. He found the brushes were bad on the carriage motor. As it turned out one of them was cracked. Replaced the brushes and it was up and running like nothing happened. I know it was stated to check the brushes but I was looking at the gantry motor brushes because thats where it appeared the error was being generated from based on what was moving and when it sent the error.
I really appreciate everyones help on this situation!
