Installation
Print Test
To check whether the printer is installed correctly, simply run a print test.
To run the print test:
• Make sure there is paper in the input tray.
• Power the printer off and then on again while pressing the Install Cartridge
button.
• The printer will load a sheet of paper and begin to print the test. The mono-
chrome print test is four pages long, the color print test one page long.
• The test ends when all pages have been printed; the printer is now ready to
be connected to the personal computer.
With this test you can check whether the printer works correctly, you can
obtain a printout of the printer's configuration data and view its default Setup
parameters.
Connecting the Printer to the Computer
Centronics Parallel Interface
This interface is a standard component on the printer; no additional options are
required.
Handshaking is synchronized by the character strobe signal, issued from the
system, and by the BUSY signal issued from the printer.
