JP-1000 (260-2960) Self Test Faxback Doc. # 15059 To invoke the self-test on the JP-1000, hold down the INSTALL CARTRIDGE key while switching on the printer. Be sure you have plenty of paper in the paper tray and the print head is inserted. With the black cartridge installed, a four page printout results. When the color cartridge is installed, the print test is only one page to test the three colors of the cartridge, cyan, magenta, and yellow. (ABO/all-04/19/95)
