Just to clarify; did replacing the encoder disc and sensor stop the void lines from occurring? Or is it still happening?

The PCA had a 01.1.......code if I remember right. I will talk with the customer about the error. I think the biggest thing is the void lines. I'll have them test that for a bit.Leave a comment:

No, you just stick the disc on. It doesn't matter the orientation. Was the old one contaminated or damaged in any way?
If the end user can't live with the occasional error when turning on the printer, I would suggest just leaving it powered on. Maybe you got a defective sensor. Or maybe it is a defective engine PCA despite that it's been replaced. What was the cause for replacing the engine PCA?

My apologies on my wording. Yes, I replaced the disk and the sensor, not the motor. The engine PCA was replaced about 2 months ago. It was an HP genuine part. Is there any type of orientation for the encoder disk? It is just held on by adhsive. I matched up the position with the original one.Leave a comment:

I hope you mean you replaced the encoder disc and sensor, not motor. The motors rarely ever fail. If not, I would replace the sensor as I mentioned. If you still get an error then get a new electronics module (not the formatter.)

I did replace both the encoder disk and motor, ran the calibration tests for them and reset the media advance calibration. Now, I am getting an 81.01 on every boot up. It never finds an error though. I reboot it and it is fine for a day or 2 and then comes back.Leave a comment:

Re: HP designjet T1300 Void lines
Check out this post: T1200 MFP printer/scanner question
Scroll to page 7.
The problem was with a dirty encoder disk on the paper advance motor that kept getting contaminated with grease that came from underneath the spittoon cup. A gob of grease was under there and the encoder disk kept getting grease on it. Came from the factory that way. It caused the same problem you're experiencing. We had the local HP techs come out and work on it and they replaced the paper advance transmission, charged us a lot of money and never solved the problem. You might want to read through the whole thread because Kiran has some good information/advice in there.
Anyway, it's something else to check. Disks are cheap and easy to replace. Or just a good cleaning might do it.Leave a comment:

Re: HP designjet T1300 Void lines
I assume the blank spaces run horizontal, as in the same direction as the carriage. Which means you have a media advance issue. Are they printing in 'fast' or draft mode? This is a common result if so. If they print at a higher quality (more passes of the carriage) it will (should) go away.
Since it's uneven though, I would suspect the media advance encoder and encoder disc.
CR647-67023 is the encoder sensor
CH538-67073 is the encoder disc. Please verify these part numbers yourself.
Also I would not rely on the media advance calibration. Go back to it and reset it to the factory default.

HP designjet T1300 Void lines
I got this call for void lines but, it doesn't happen all the time. It seems completely random. I could not calibrate colors or update Firmware and was gettin a 48: and 86: code at random. HP said to replace the engine PCA/EE box and thought I had it. Guess not. I ran color calibration and paper advance calibrations and they came out good. left and now it is back again. It acts like a feed issue as the print is scrunched up, not deleted. I cannot make it happen while I am there. The encoder strip has been cleaned but, I wonder if I should just order one anyway?? Here is what it looks like.
