4069-5XX/7XX Problems with excessive static electricity buildup. FRU 1 Front Cover Assembly Action Check the front cover assembly to make sure the ESD brush ground lead is firmly attached to the 5-Bin Mailbox frame. Also check to make sure the ESD brush is not loose or damaged. The printer does not recognize one or more output options as installed. Service Tip: If more than a single output option is installed, check each one to see if the printer recognizes any single option as being installed. If the printer recognizes any of the output options then the base printer autoconnect system is operating correctly and the problem is in the unrecognized option. Continue with this service check or go to the service check for the failing output option. FRU 1 5-Bin Mailbox Option 2 Mechanical Linkage Assembly Action Check the autoconnects, cables and connectors of the option for any signs of loose or damaged parts. Remove the left and right side covers and check the two autoconnects for damage especially the connector pins. Remove the output option and check the voltages on the standard output bin autoconnect located on the top left rear of the printer. Go to "Autoconnect - Top" on page 5-11. If the voltages are correct, reinstall the output option noting the position of the toroid on the autoconnect cable of the lower autoconnect. Check the voltages on each of the autoconnects. If the toroid was moved make sure to move it back to its original position on the cable. If the voltages are correct, replace the control board. If the voltages are incorrect, replace the failing autoconnect assembly. 2-100 Service Manual
