HP Recommended
Product: Designjet 500 24"
Operating System: Microsoft Windows 7 (32-bit)

I have a second hand Designjet 500 24" printer.

 

There are white lines on the prints, a double white line, a space, then again.

 

I have tried the advanced paper calibration and get exactly the same effect.

 

I have changed the black print head and it made no difference.

 

I replaced the belt because the old one was disintegrating.

 

I don't know if the problem existed before the belt change.

 

Any advice would be gratefully received.  Thank you.

 

Further Information:

 

Today I have performed all the paper advance tests as detailed in the manual, Page 1-17, and it looks like the encoder disk is damaged.

 

Images attached.
