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

[kulbros]

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?

It could be the servo board if both motors have the same symptoms so that would be the next thing to try

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

OK change the servo board and see if that fixes it

Once more a big thank you.
Will do and let everyone know here the results.
