Remedy: Bad checksum while programming Standard Network or Network Card x port. Check the following: • Make sure you have downloaded the code in binary mode, not ASCII. • Reprogram the Network card. • If the problem persists, and if installed, check the network card for correct installation. • If correctly installed, replace the network card. • If a network card is not installed, replace the system board
Code: 979.xx
Description: Standard Network or Network Card X
Remedy: Flash parts failed while programming the Standard Network or Network Card x port. Check the following: • If installed, check the network card for correct installation. • If correctly installed, replace the network card. • If a network card is not installed, replace the system board.
Code: 982.xx
Description: <device> comm. Communications error detected by the specified device. Note: <device> can be one of the following: • Duplex option. • Tray x (where x=2, 3, or 4). • Output Expander or StapleSmart finisher—Output bin x (where x=1). • 5-Bin Mailbox—Output bin x (where x=1 through 5).
Remedy: 1 Are the output options not recognized? Go to step 2 Go to step 4 2 Remove the output option, and reinstall it on the printer. Power on the printer. Does this fix the problem? Replace the output option. Replace the top option autoconnect cable. 3 Remove the input option, and reinstall it on the printer. Power on the printer. Does this fix the problem? Problem resolved Go to step 4 4 Voltage check, base printer autoconnect connector— Turn the power off, and remove the output option from the printer. Check the voltages on the base printer top autoconnect connector. See “Autoconnect—top”. Are the voltages correct? Replace the output option. Replace the bottom option autoconnect cable.
Code: 990.01
Description: <device> This error message indicates that an equipment check condition has occurred in the specified device, but the error is unable to identify the exact component failure
Remedy: 5-Bin mailbox 1 Mechanical linkage/DC motor assembly—Check the DC motor cable connector to make sure it is installed at J4 on the control board. Is the cable connected correctly? Go to step 2 Reseat the cable, and recheck for correct operation of the option 2 Resistance check—Disconnect J4 from the option board, and check the resistance of the motor on the cable connector between J2-1 and J2-2. The resistance measures between 115 and 135 ohms. Is the resistance correct? Go to step 3 Replace the mechanical linkage/DC motor assembly. 3 DC motor—Check between J2-1 and between J2-2 and the case of the DC motor for shorts. Is the DC motor shorted? Note: If the DC motor is shorted, damage may result to the control board. Replace the mechanical linkage/DC motor assembly. Go to step 4 4 Output expander control board check—Disconnect the motor cable J2, and check the voltages at J2 on the board. Warning: Be careful not to short to adjacent pins on the connector. The voltages measure: (Note: All voltages are approximate values.) Are the voltages correct? Replace the control board. Replace the mechanical linkage/DC motor assembly. 500-sheet drawer option 1 Make sure the autocompensator cable is correctly installed at the tray system board. Is the cable correctly installed? Go to step 2 Install the cable correctly. 2 Make sure the drive assembly cable is connected correctly to the tray system board. Is the cable correctly installed? Go to step 3 Install the cable correctly. 3 Check for worn or broken parts in the autocompensator and drive assemblies. Are any parts worn, broken, or damaged? Replace the assembly that has the defective parts. Replace the FRUs in the following order: 1. Electronic/ size sensing assembly. 2. Autocompensator assembly. 3. Drive Assembly. Output expander 1 Mechanical linkage/DC motor assembly—Make sure the DC motor cable connector is installed at J4 on the output expander control board. Is the cable connected correctly? Go to step 2 Reseat the cable, and recheck for correct operation of the option. 2 Resistance check—Disconnect J4 from the option board, and check the resistance of the motor on the cable connector between J4-1 and J4-2. The resistance should measure between 115 and 135 ohms. Is the resistance correct? Go to step 3 Replace the mechanical linkage/DC motor assembly. 3 DC motor—Check between J4-1 and between J4-2 and the case of the DC motor for shorts. Is the DC motor shorted? Note: If the DC motor is shorted, the system board may be damaged. Replace the mechanical linkage/DC motor assembly. Go to step 4 4 Output expander control board check—Disconnect the motor cable at J4, and check the voltages at J4 on the board. Warning: Be careful not to short to adjacent pins on the connector. The voltages measure approximately: Are the voltages correct? Replace the output expander control board. Replace the mechanical linkage/DC motor assembly. StapleSmart finisher Step1—During POST, the stapler option does not try to home. Replace the stapler option. Step 2—During POST, the stapler option tries to home. Replace the stapler option.
