Need Help VS-640i - Service Call 0330 and 0109 errors after scan motor change

Hello everyone and many thanks to all the people who contribute to this extremely helpful forum.

So here is my story.
Printer (VS-640i) worked fine, except not so loud noises made by a scan motor. About a month ago it stopped during printing (twice) with "motor error ..." but I could print again after rail bearings lubrication, which probably reduced the resistance. After 3 weeks of flawless printing, the noise became lauder, so I decided to change the motor.
Here's what happened after replacing it with a new one (OEM or at least looks like one):
- first power-on: some noises from motor, no movement, "motor error ..." on display (sorry, don't remember the digit codes)- then I could only turn it off in the back;
- second power-on: similar noises together with rhythmical up/down movement of cutting knife, "service call 0330";
- third power-on: similar to second one but with "service call 0109".

At this point I decided to switch back to the old motor, to check if it's a new motor's fault. Unfortunately (almost) nothing's changed.
Now every time I turn on, I only get a quiet clicking from the motor (without movement) and one of the errors (0330 or 0109) - no up/down knife movement anymore.
Mechanically all seems to be fine: I can move the carriage by hand freely without noise. Also all the connections I could visually check seem fine.
Definitely something went wrong electrically because of motor changing (or I did something wrong). Seems it's all related to the servo board (mentioned knife behaviour, engine clicking, error types).

Considering I'm not a qualified technician, is there anything I could do now to confirm what's broken or at least to narrow down possible causes?
Or should I just order a new servo board?
Any suggestion would be appreciated.

Where did you get the new motor from? Most of them are chinese copies, not OEM and often fail quickly or don't work at all
It could be the servo board if both motors have the same symptoms so that would be the next thing to try
 
The 0109 error is for the wiper. Very common on VS, sometimes on VSi make sure the wiper is oriented in the home position, that is, with the rubber wiper 45° to the back.
You can test this in Service Mode
The 0330 is for the choke valve sensor, can be tested in Server Mode.

Please confirm the size of the brass gear on your new motor versus your old motor and see if they are the same, if so, you are good.
There was a mod on VS models (not VSi), not sure what part # you purchased.
Current VSi scan motor: Roland Part # 6000002594
Yes, could all be the Servo Board.

Thanks a lot for quick response.

Motor bought from Digiprint Supplies - part no. 6000002594, sticker says "Nidec - Made in Japan" (yes, I know - just a sticker), right size of the gear (11,8 mm diameter).

The 0109 error is for the wiper. Very common on VS, sometimes on VSi make sure the wiper is oriented in the home position, that is, with the rubber wiper 45° to the back.

Thanks, I can try to test, however before motor change I've never had these errors so I think it's rather a symptom of another failure.
Never used the Service Mode though: if servo board is dead (partially maybe), would be still possible to perform such tests? Or any other tests to confirm my suspicions towards servo board?

Ok, so based on your experience (which is enormous, as I can tell by browsing the forum), this would be the next step even if it means to spend quite a lot of money and knowing it's non-refundable?
New servo board would cost over 800$ (from the same source as motor) so I want to be as sure as possible that nothing else left to be checked.

And one more question: considering the printer is plugged off for 10 days now (of course with carriage parked on cap), how much longer I can think, not act, without causing damage to the head?

OK if it came from digiprint it is almost certainly a chinese copy. I wouldnt trust most of the boards they sell either
I would look on ebay for a working used board. If this doesnt fix the problem you can then return it under their buyer protection.
The other thing you can try is fitting a known working used OEM motor. I have refurbished ones in stock if you need one which is a cheaper opton/
You can also fit your motor to the printer, but not connect it up to the pulley. When you start the printer you should be able to see if the motor turns at all.If it does then it could be a problem with the bearings or drive to the print carriage

If so, could I have damaged the servo board by just turning the printer on with correctly installed new motor?

Ignoring all "Located in China", for VS-640i I can see only one, new with price as in Digiprint (box looks the same, so can be a chinese copy as well).
Used ones are for VS-540i or VP-540 - have no idea if I could use any of them for 640i, besides there's "seller does not accept returns" disclaimer everywhere.

OK but currently I have my old OEM motor installed (originally from this printer and never changed before), which was working before, just generating bearing noises and, as I wrote before, I get same errors as with new motor from Digiprint. Does it make sense to test with another OEM motor then?

OK, just checked with motor gear not connected to the pulley (still with old motor) - basically the same status as with motor connected:
- motor doesn't turns, just clicks, making regular micromovements (like trying to turn but without turning - I would say one per second);
- wiper also does a similar thing (micromovements one per second, without changing position - like just trying to turn);
- after a few seconds error 0109 shows and wiper stops "moving", while motor still clicks for as long as I won't turn the rear swith off.

OK change the servo board and see if that fixes it as other than trying another motor then there isnt really anything else you can test

Have you checked the power supplies? Could be a problem with the 41V.
I did not, since I didn't think changing only the motor could affect power supply. Could you please let me know where I should check it? Some fuse and/or plug?
Should I check also supply in scan motor plug (this one is 24V though)?

It is very unlikely to be a power supply issue as the motor wouldn't have tried to move at all before if it was. The power supply has two outputs, 5V to run the chips and 41V for the heads and this is also stepped down to provide the 24 and 12V for all the motors.

Thanks for clarification - I will stick with servo board malfunction idea then.

Quick update: thanks to courtesy of one of technicians, I could make tests with used but checked servo board. The printer is working with it and when I switch back to our servo board, it generates Service call 0330 error immediately.
So almost for sure the servo board is broken. Will post when get & install a new one.

Good stuff at least you have narrowed it down
Yes, but there is more.
Since with my old motor I couldn't test properly (was giving me 0010 error constantly), the owner of servo board agreed to test it with my brand new motor (bought from Digiprint) - the one that caused whole mess (or at least I assumed so). Surprisingly, printer with borrowed servo board and this new motor started immediately with no errors and works normally.
So it seems the first connecting of this motor resulted with dead servo board but the same motor with another board is OK. Doesn't make much sense to me but I probably have not enough knowledge or missing something between.
Still, I have to buy new servo board and that would end the story but... during last tests, with new motor, I have noticed something strange happened to colours.
Just after installing of good servo board, still with old motor, apart of standard test I've printed a "control" file with big CMYK rectangles, to check quality and pump some ink through printing head (having in mind it was unused for 2 weeks) - all was ok and shades were how they used to be before.
Today, after plugging new motor I've done some printings with black background and noticed it was lighter then before, little more brownish. So I've printed the same control file as two days ago, with same settings, same foil and same profile and it confirmed my observation: black is significantly less black. Also cyan is less saturated, while M and Y are almost unchanged.
During these two days between both control printings, I've only changed old motor to a new one and cleaned encoder strip (because, as I mentioned, with old motor there was 0010 error). My plan was to clean also encoder sensor but decided to not remove the head/carriage board (cables were inserted firmly), so just blew some air through it (not compressed). That's it.
Printing test shows no clogged nozzles (all are ok) and there are no other flaws in prints. I can obtain nice black but have to use multichannel (e.g. CMYK 60/60/60/100) or use special colour from Roland palette, which I never had to do before. For 7 years of printing, the black was black enough with just K=100.
How the change in colours is connected to what I did with the printer is beyond me.
Any ideas?

Very strange but it sounds like the new motor is moving too fast so the heads can't lay down the normal amount of ink. The problem is definitely with the motor if everything else is the same and that is all you changed.

The printer will still think it is working fine but if the head moves slightly too quickly you get less ink on the vinyl.

I can't think of any other reason that would cause it as both motors should work at the same speed but with the Chinese copies digiprint sell you can never be sure!

It may be a case of just having to live with it and adjust your settings to give the best print. Or get an actual original motor you know will be the same as your old one

Many thanks for responding so fast, damonCA21.
I wouldn't thought about it by myself but I agree it sounds like the only logical explanation.
I think I will try to print at least one file with old motor, to confirm the idea.
Still, is there anything I could have done accidentally to cause such strange colour symptomps?

No not really if all you have done is swap the motor. Not sure if anyone else has seen this before but the Chinese copy parts can often cause weird problems

Run the scan aging in service mode and see if that makes any difference. Aging should be done anytime you change a motor anyway.
