What To Do If …
CX400 is very reliable, so printing problems are unlikely. If you do
think you have a printer problem, proceed as follows:
Confirm that the printer has the right media installed, and that it is
loaded correctly. See page 5 for media loading instructions.
1. Confirm that the printer is connected to its power supply and the
supply is plugged into an AC outlet having the proper voltage.
2. Open the print head and inspect the media path. Remove any
obstructions, and clean the print head and drive roller according
to the instructions on page 12.
