Paper Handling Problems Print Test Pages To confirm that the printer can pick and move paper, generate a Self-Test / Configuration page by depressing the GO and JOB CANCEL buttons simultaneously when the printer is in a ready state. If the printer can not produce a Self-Test / Configuration Page, generate an Engine Test Page. If an Engine Test page does not print, see "Paper Jam Troubleshooting" (page 105). Engine Test The engine test verifies that the print engine is functioning correctly. It is also useful for checking and adjusting registration.This test is very useful for isolating printer problems, because it does not involve the Formatter PCB. The engine test prints a full page of lines across the entire printable area. See "Microswitch Control" (page 78) for instructions on performing an engine test. NOTE: Ensure that the Toner Cartridge is installed in the printer. Also, the print motor must be stationary and the printer must be in the standby mode. In order for an engine test print to be produced, paper must be loaded in the printer. The system checks for paper first in Tray 2, then Tray 1, and then in the optional Tray 3. Paper is pulled from the first tray containing paper. NOTE: Self-Test / Configuration Page Use the Configuration Page to view the current printer settings, to help troubleshoot printer problems, or to verify installation of optional accessories, such as memory (DIMMs), JetDirect cards, and printer languages. If Status Log information is present, it will print in the Status area of the Configuration Page. If an HP JetDirect print server EIO card is installed, a JetDirect Configuration Page will also be generated. See "Printing Self-Test/Configuration Page" (page 46) for a sample page. Paper Jam Troubleshooting Paper jams occur in the printer when paper does not reach or clear a photosensor along the printer's paper path in a specific amount of time. The following table contains general questions and topics to explore prior to troubleshooting. C4170-90959 Paper Handling Problems 105
