Optra family; The 900 error is usually due to a software or communications problem.
If the 900 error occurs only when the printer is receiving information from a network or computer, you should contact your software/network support. If the error occurs when the printer is idle or not connected to the network or PC, there may be a printer hardware or connection problem. Sometimes a bad connection with an Internal Network Adapter/Network Card can cause the problem. The first thing to check is the base printer. To check the base printer:
Turn off the printer and disconnect every cable, except for the power cord.
Turn on the printer and see if the error returns.
If not, try to print a test page from the Test Menu (MENUS, TESTS MENU, MORE, Print Menus).
If the test page prints correctly, the printer's hardware is most likely working correctly. The source of the problem is probably outside the base printer.
If the 900 error occurs again before, during, or after the printing of the test page, remove all options (internal network adapters, rear feeders, second drawer options, additional memory, etc.) from the printer.
Then turn on the printer and try to print the test page. If it still posts the 900 error, the printer may need to be serviced. If the error does not return, the problem may lie with one of the options. You can test them as directed below.
To check the installed options: When you have verified that the base printer is not the problem, start testing any options you have. Note: The power cord should still be the only cable connected to the printer.
Turn off the printer and install the options, one by one.
After each installation, turn the printer back on and try to print a test page.
If the error returns, you have found the problem option. With that information, you should call for service.
The error may not return with all of the options reinstalled on the printer. Test the printer with all of the options installed by printing the test page again.
If it still passes, the problem may be with the communication or connection. You can test for this as directed below.
To check connectivity: After you have successfully printed test pages with all of the options back on the printer, you are ready to reconnect the printer to the network or PC.
Turn off the power and connect the network or PC cable.
If you have more than one connection, you should try each connection separately.
If the error doesn't return and you are able to print without a problem, there may have been just a bad connection.
If the error does return, something may be wrong with either the network's or PC's communication with the printer. Contact your software/network support. There are also a few settings on the printer that can cause this error to occur. See below.
Checking the printer settings: There are three settings on your printer that can cause this error to occur if they are not set correctly.
Print a menu settings page as follows:
Press the button next to Menus.
Press the button next to Tests Menu. If Tests Menu is not listed, press More until you find it.
Press the More button until you find Print Menus.
Select Print Menus. A menu settings page will print out.
Look under Parallel Setup and Serial Setup for the following three settings: NPA mode PCL Smartswitch PS Smartswitch. Both the NPA mode settings should be on AUTO. All four Smartswitch settings should be set to ON. If any of these settings is not correct, you will need to go into the printer menus and change them. They are listed under SETUP MENU, and then PARALLEL SETUP or SERIAL SETUP. For example, to change the PCL Smartswitch under the printer menus:
Press the button next to Menus.
Press the button next to Setup Menu.
Press the More button until you find Serial Setup.
Press the button next to Serial Setup. Look for PCL Smartswitch.
Press the button next to PCL Smartswitch. You will see all of the available settings. The setting with the asterisk (*) next to it is the one that is currently selected.
To change that setting, press the button next to the setting you want to change it to. The asterisk will move to the new choice and the printer will briefly flash SAVED.
Repeatedly press the RETURN button until the printer is back to a READY status.
If none of these tips helps to resolve the issue, there may be a problem with one of your network or driver settings, or with one of the main logic boards on the printer. Based on the results from the tests above, you should be able to determine the type of the problem you are experiencing.
