Re: Should she leave the power on all the time?
No, shut it down. The enemy of electronic components is heat. Besides, it wastes energy. If everyone in America who left their computers on overnight would shut them off we could have one less nuclear power plant in the US.
As a general rule, you need to look at two things to answer this question:
1.) Do you have a good, clean, generallyuninterrupted supply of electricity? If so, then it won't HURT to leave it turned on all the time; but if not, you'd be best to turn it off, and even unplug it during storms and other times of like power outages. Power spikes and surges can totally ruin any electronic equipment, and printers are no exception.
2.) Does the equipment manufacturer recommend that you leave it on all the time? If so, by all means, do so. If not, it's a judgement call. Two factors that influence that decision:
Some printers take an inordinate amount of time to warm up and cycle to ready—if yours does, you may want to leave it on.
Some printers also use a whole lot of ink when they first cycle to ready, so if yours does this, it will be more economical to pay for the electricity than to pay for the ink.

If i remember correctly you can just hold 2+6 on boot up to put you in the config mode. Next find factory defaults reset the LES (Lexmark Embedded Solutions) Base Codes and Standard Network. That should put you back to defaults.Some times it can have a add-on expansion card with memory/setup you can remove. If there is a password blocking access the system board has a jumper you can use to reset that just like a PC BIOS.
A 921error indicates that the fuser
unit failed to reach the standby temperature.
If this is the first time you have seen the error, turn the printer off and
on. Leave the printer off for at. least 10 seconds before turning it back on.
This gives the printer's engine board a chance to reset.
If this is an intermittent error, you may want to check how the printer is
plugged in, even if it has worked on this surge device for months. Make sure
the printer is plugged straight to the wall and not through a surge device or
power strip. Power strips and uninterrupted power supplies can cause a low
amperage problem in your printer which can trigger a false fuser error.
If this does not help or if this error appears every time the printer is
powered on, you will probably need service on the machine.
If you need further assistance please contact Lexmark Technical Support or any Lexmark authorized service provider.

We recommend you choose to save the file within a directory on your computer's hard drive. Once it has been saved, go ahead and run the file. The downloaded files are self-extracting ZIP files. Running this file will create a set of .PJL files and a file entitled Readme.1st. The Readme.1st file also contains directions for sending the file over through a parallel connection.
Power on the printer without the printer or networkcable attached. Check if you can print a test page. If this works there is a printjob in the system that should be deleted before connecting the printer to your computer or network.
I have the same problem, but the error only occurs when I try to print a .pdf file (Adobe Reader) using the "Lexmark Optra SC 1275 PS" driver. For some reason the PS driver didn't like .pdf files! My solution was to always print .pdf files using the alternative " Lexmark Optra SC 1275 (MS)" driver, which Lexmark also offers on its website.
