           Troubleshooting steps

The printer displays a 49.XXXX error on the control panel. 49.XXXX errors, including 49.FF04,
49.FF07, 49.FF08, and 49.FF09 could be hardware or software errors. The error could be
caused by third-party memory, improperly installed or third-party EIO devices or a specific print
job and/or software application.

Determine if the error is software or hardware by resending any jobs in progress, sending a
different job from another software application, or changing the size of the current job. If the error
is still present with other applications or jobs, continue with the troubleshooting steps in the next

Troubleshooting steps
    1. Verify that the formatter light is blinking or steady. If the formatter is blinking, it is
       functioning properly and probably does not need to be replaced. If the formatter light is
       not blinking, proceed to Step 2.
    2. Turn off the printer and unplug the power cord.
    3. Remove the HP Jetdirect card, third-party device, hard disk, parallel cable, or IFR cable
       from the formatter if one is installed.
    4. If the error continues with accessories removed from the formatter, perform a cold reset
       on the printer. Ensure the HP Jetdirect card is not in the printer during a cold reset or the
       card settings will be changed back to default settings. To perform a cold reset, do the
            a. Turn on the printer.
            b. Watch the control panel.
            c. When the memory starts counting, press and hold the green (Select) button.
            d. Continue holding the green check button until the Ready, Data, and Attention
                 lights flash once, and then stay on steady.
            e. Release the check button when the Ready, Data, and Attention light are on

                 The control panel will display SELECT LANGUAGE.

            f.   Press  (Down Arrow) button once. The control panel will display COLD
           g. Press (Select). The printer will perform a cold reset and then continue its
                power-on sequence.
5.    If the printer comes up to ready, print a Configuration page. If a 49 error occurs from
      printing internal pages, continue on to the next step.
6.    Turn the printer off and unplug the power cord.
7.    Remove the eight screws around the formatter.
8.    Remove the formatter. See Figure 1.
9.    Reseat the firmware and memory modules on the formatter. Check for any DIMMs that
      are non-HP and remove them. Non-HP DIMMs are not supported by HP and may cause
      this error. Replace with HP DIMMs, if necessary.
10.   Reseat the daughter (interconnect) board. The daughter board is connected to the
      formatter behind EIO slot #1. To release the daughter board, push in the black retaining
      tab underneath the formatter (see Figure 1, call-out 1), then lift up the one side of the
      daughter board.

11. Reseat the daughter board. See Figure 2.

12. Install the formatter.
13. Turn the printer on again.
14. If it comes up to READY, print a configuration page. If a 49 error does not appear from
    printing internal pages, or at power up, continue to the next step.

            NOTE: If a 49 error does appear when printing internal pages, call HP Customer
            Care for assistance.

15. Install the HP Jetdirect card and hard disk before installing the formatter. Verify that each
    device is properly seated.
16. Test any EIO devices, by turning off the printer, installing each device separately, and
    printing a Configuration page. Repeat for each EIO device.
17. If the 49 error occurs with any EIO device installed, replace that EIO device.
