Review the following information before performing any service checks.

•Paper feed problems (especially paper jams): Go to “Display Log” on page 3-23and check the printer event log for indications of repetitive entries that help to isolate a problem to a particular area of the printer or option.

•Paper feed problems with error message: Use the “Sub error codes for 9xx and 2xx error codes” on page 2-8to help diagnose the problem.

•Print quality problems: Go to “Print quality pages (Prt Quality Pgs)” on page 3-6and print a test page to help diagnose problems before changing any settings or working on the printer.

•Use the resident diagnostics test provided to help isolate a problem before taking the machine apart or removing any options.

5-Bin mailbox service check

Service tip: The majority of the mechanical components can be observed during operation by removing the left and right side covers.

Make sure the option(s) are correctly installed and the machine is configured correctly before attempting to service the unit.

Problems with excessive static electricity buildup

	FRU	Action
1	Front cover assembly	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	Action
1	5-Bin mailbox option	Check the autoconnects, cables, and connectors of the option for any
		signs of loose or damaged parts.
2	Mechanical linkage	Remove the left and right side covers and check the two
	assembly	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” on page 5-6. 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.
