Degradrawer Missing is displayed constantly. Can't override this.

check the top of the tape cassette if plastic removable tabs missing it will behave like a read only cassette if missing sticky tape can be used to cover the holes to make cassette recordable.

@Derekns74 How do you remove the switch? My C3000 also reads "EMPTY TRAY" constantly, even if the tray is empty and clean. It does not display the "EMPTY GROUNDS" error only "EMPTY TRAY"

If I remove the tray it display "TRAY MISSING" but whenever I insert the tray again, it reads "EMPTY TRAY"

On one occasion when our power went out, it fixed the machine, so that it stopped reading "EMPTY TRAY," but after a day or two it stopped working and displayed the same EMPTY TRAY error message again.

I have 59377 timer in my office.
Here is copy of manual:

What job do want the timer to do?
It sounds like you want a programmable timer at night, and simple on-off switch at day.
Add a comment if answer below misses the mark.

YES, the manual override can be used as on-off switch.
Press manual override until Manual ON or Manual OFF display.

The manual override button has 4 states:
Auto ON, turns lamp ON immediately and programming resumes at next set time.
Auto OFF, turns lamp OFF immediately and programming resumes at next set time.
Manual ON to choose permanent ON.
Manual OFF to choose permanently OFF.

SHOULD BE A THIN CABLE ON THE SAME SIDE AS THE FILLER DOOR IS,IF ITS MISSING ALL YOU HAVE TO DO GET TO THE INSIDE OF THE FENDER WELL AND LOCATE THE RELEASE LEVER.
HOPE THIS HELPS

Please disable the User Account Control feature.
You can disable the UAC from User Accounts in Control Panel. Also, reinstlal the Video Driver to resolve the issue

The problem is most likely the switches on the front panel. If the manual buttons are constantly shorting out, then the TV will try to respond to those buttons, and not the remote. Manual buttons almost always override a remote. Check the front panel for shorts, or if the buttons are constantly depressed.

I seem to be having the exact opposite problem. I have a 99 chevy blazer and the dome light will not turn off unless I push the override button in. The radio does turn off as soon as I turn off the ignition key. If I leave the dome override button out, the dome light will constantly stay on even while I am driving. It used to work fine. Every now and them it starts working properly, but it hasn't worked right for a long time now. I tested all the switches and they all seem ok. They rear hatch is also closed. Does anyone know what the problem can be and how to fix it?

Check you have not set the paper source to "Letter" in Printing Preferences if so chnge it to "A4"

Right Click to get this option when you are in "Printers and Faxes"

Also check "Page Setup" in the program from which you are trying to print as these options override those set in "Printing Preferences"

The only way to clear it is to replace the fuser rollers or the thermistor.  Clear code isn't available for override.
