Answer : Problem: Who offers repair/refurbishment services for the HP 9100C Digital Sender?

For the couple of digital senders we have, I use a local printer repair company.  Any place that repairs scanners should also be able to work on the digital senders.

This link is to the Business Support Center for the 9100.  See if any of their documents help you with your problem.

If not, then I'd suggest chatting with an HP rep to see if they can recommend an HP authorized service company in your area.  They don't have this information available online.  Click the Products supported link under Chat online with HP:
