SP540 V printing problem

[Mattc]

Hi!
I suddenly have this problem.
I had no proble printing couple of hours ago, but suddenly, printing is very noisy and it seems like print head is keep sliding to left side as media is feed. Also, it printer shows occational Carriage are disconnected" error. I have a few printings have to be done for my client tomorrow. What do I have to do? Please help me.

I fixed the problem by myself. I went CVS and bought alcohol swab.
I cleaned encoding strip with it, and now the printer is back on to normal.

How many hours on the scan/feed motors?
Hopefully it is just the encoder strip as mentioned.

I don't know the hours on motors.

I thought I fixed the problem. Actualy it is better, but not fixed.
Now It is not sliding much but vertical alignments are tiny bit off every 3 inchs. I think I have to call tech to look at.

Finally! Fixed!
I am glad I fixed it before I call service tech. I save few hundred dallars!
I serched google and it direct me back to Signs101.com.:signs101:

I tried remove encoder strip to clean and put it back on. No luck, So i removed it again and put it upside down, and it is even worse. Keep having Carriage disconnect error. So I cleaned sensor. And finally, it is printing flawlessly!

Thank you all those people who share valuable information and experience!
Now I am back on to my project!
