Sorry this took so long, but I found a suggestion. I have never seen the printer or anything like it, I had to source the information from someone in France (I'm Canadian)
You have to go under Parameter Initialization Menu
And init the pump counter.

Nous avons an unusual
code E-162 on Xerox /Mitoh/ 7142 plotter.
The code appears after the replacement of the plotters pump.
This code is not described in our services manual ; perhaps due to the fact that the later dates back to 2007.
Thank you very much in advance
