During the test, the print cartridge head goes through a maintenance cleaning at the maintenance station.
4076-0XX Test Page Perform this test with a black print cartridge installed. This test repeatedly prints the nozzle test pattern followed by a sample of each font installed in the printer including resident fonts as well as fonts stored in FLASH memory. This test continues until you press the Reset button or turn off the printer. The error number is the last number to print on the page in the lower right corner. Paper Sensor Test Release the buttons after the maintenance station uncaps the print head.

The printer motors are disabled during this test to allow you to manually move the carrier to verify the encoder is working correctly.
76-0XX Parallel Port Test This test requires a parallel port wrap plug. Install the wrap plug in the parallel port before you start the test. This test performs a wraparound test between the printer parallel port and the parallel port test connector. If the test is successful, the top two lights and bottom two lights blink alternately. If the test is not successful, only the bottom two lights will blink. Initialize Nvram Use this procedure to reset the error log portion of NVRAM.
4076-0XX Serial Adapter Test Perform this test with a black print cartridge installed. This test checks out the connection between the serial adapter and the printer. To run the test: 1.
