Thanks for the link. I downloaded the 6 files and used WINACE to try to extract the files. I put all six RAR files in one directory, and started the extraction with Part1. It created a PDF that appears to be the entire Z2100/3100 manual, of some 16 0r 17mb.
When I tried to extract parts 2-6 I got error messages. However, I think I got the whole manual in PDF form. It has chapters (parts) 1-9. Is that all?
The info is very useful. It mentions a cleaning utility part that is supposed to come with the Z3100, but I do not remember seeing it when I unpacked the printer. Did other people get this?
