HP4550 - 49.00FF service error
Turn off the RAM disk on the printer.
Follow these steps:
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.
Turn off the printer and unplug the power cord.
Remove the HP Jetdirect card, third-party device, hard disk, parallel cable, or IFR cable from the formatter if one is installed.
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 following:
Turn on the printer.
Watch the control panel.
When the memory starts counting, press and hold the green (Select ) button.
Continue holding the green check button until the Ready, Data, and Attention lights flash once, and then stay on steady.
Release the check button when the Ready, Data, and Attention light are on steady.
The control panel will display SELECT LANGUAGE .
Press (Down Arrow ) button once. The control panel will display COLD RESET
Press (Select ). The printer will perform a cold reset and then continue its power-on sequence.
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.
Turn the printer off and unplug the power cord.
Remove the eight screws around the formatter.
Remove the formatter. See Figure 1.
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.
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 then lift up the one side of the daughter board.
Reseat the daughter board.
Install the formatter.
Turn the printer on again.
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.
Install the HP Jetdirect card and hard disk before installing the formatter. Verify that each device is properly seated.
Test any EIO devices, by turning off the printer, installing each device separately, and printing a Configuration page. Repeat for each EIO device.
If the 49 error occurs with any EIO device installed, replace that EIO device.
