HP 560 SMK3 issues

[JBurton]

I just had my SMK3 performed by a tech. Now I'm having a couple of issues. I've emailed the team at my distributor, and am waiting for their response, so I reckoned I ask here too.
1. the printer kept asking to move material left by 480 mils during load. I finally continued with skew, then it told me it could not detect material width. I'm thinking there's something amiss with the sensor.
2. I went on and ran a print, it started off just fine, but after a foot or so it began printing very splotchy. Upon closer inspection, it also was banding slightly prior to the splotchy region, and it was running at 20 pass, comparing to the last print of the same file, there is no banding.
3. Do I need to lubricate the rail after this kit? I figured it would have been part of the tech's procedure, but it sounds rather loud, and has an almost fluttery sound to it as it goes right to left. About to lubricate and run another test.

Either the line sensor is not seated correctly or he didn't calibrate it.
By the picture your optimizer printhead is gone.
Just oil it. He should have done it but yeah..

The tech is going to call tomorrow morning to walk me through reseating the line sensor.
Welp, the one print head that I don't have 2 backups on the shelf for...
On the carriage rail, we oiled it, it sounds about the same, I'm tempted to oil it again, any reason not to?

Most of the issues are caused by the service actions during SMK. I would ask for repair FOC. The Oiler on right side of carriage should apply oil in during movement. Line sensor calibration is available only in service mode. The sound of carriage movement might be caused by wrong belt position on tensioner, which will damage the belts edges.
Regarding the blurred print, it’s for sure the OP head. But could also be a kinked tube on the left side.

Ok, I'm growing a little frustrated at this. Is it not part of the procedure to run a test print after the smk?
And now all of my print heads have way more missing nozzles than before, which I can accept to a degree, but I'm wondering what the procedure for storing the printheads during the smk other than setting them on a box upside down?

 

[balstestrat]

Well to whom it is and who doesn't. I always ask the customer to print something afterwards.
And printheads I just keep in the carriage. No need to take em out, saves time not having to re-align and play with those as well.

 

[JBurton]

Alright, I appreciate your guys' help. I've got a fresh set of heads on the way, tech got me into the service menu to calibrate the line sensor.
But what about the sound out of the belt? Right now, the edges are starting to fray a touch. I'll keep a close eye on them. Is there any spot to check for proper alignment or installation?
I also noticed the carriage is causing the encoder strip to move toward the front of the printer as it passes left to right, on the right hand side. I know it vibrates, but I didn't think the carriage actually made contact with the encoder strip? Please tell me I'm mistaken and just looking for issues.

Don't use it. The belt needs to be checked. It's probably not on the correct track and you will just end up wasting it.

Well shit. You'd recommend calling out the tech again, rather than trying to check myself, right? I'm thinking unless I have a belt coming, I'll likely have a trip charge to check it, and another to install it.

 

[Hoze]

That should be covered under warranty. I believe the tech is responsible for ensuring the printer works perfectly after the service, not the user. Where are you located?

 

[balstestrat]

Sure you can check it if you wish. Usually it's messed up there behind the screen on the tensioner.

 

[JBurton]

So, I'm thinking you guys are right. Here's a pic of where mine is sitting on the pulley. Sent photos over to the tech and company, I'm going to have them put a new belt on, my cost or theirs, but I'll pretty well insist on not paying the trip charge.
Does that sound fair to anybody else?
