Installing an inkjet printer
1. Connect the printer to a computer
using the correct interface
2. Plug it in
3. Power it up
4. Windows will likely recognize you’ve
connected a new device and install
drivers for it automatically
5. If drivers aren’t installed
automatically, you can do it manually
using the materials that shipped with
the printer

Troubleshooting
Acquire information about the problem
Simplify by removing any non-critical
components, shut down unnecessary
running programs, and disconnect from the
Internet or network.
Implement by identifying probable causes
and implementing potential solutions one at
a time.
Document the error symptoms, the
components you removed from the
computer, and the solutions you tried and
whether they were successful.
