Hp laserjet 4 plus printer, message window "Ready", off line button shows red

My hp laserjet 4 plus printer was working up until a few weeks ago.  Now, the message windown says Ready, but the off line button stays red.  The button has to be green in order to print.   When I press the off line button, the light goes off, but then the message windown shows Off line.  Any suggestions?  I have no manual for this printer.

You can try to do a "Cold reset"

turn off the printer hold down  the Menu/reset button and turn it back on.

Do you hear the machine go into rotation? the 4 plus has a high pitch sound follwed by the fuser turning ( you'll know when it does it) if it doesn't go into rotation then there is another problem.

    sounds like the display panel may be bad ( where the buttons are) if it says ready and the light is red then goes to offline when you push the button there is a bad board. try changing the display panel first.

My suspiction is there is a tab on the tray that triggers a switch telling the printer what type of tray has been inserted. Your old tray is likely different from the Plus 4 tray and the printer knows it.

This is due to a formatter failure.

Try an nvram
Try doing a hard or reset or nvram:
1. Turn the printer off
2. Hold down the right arrow and the cancel button
3. Reboot the printer while holding the buttons and hold until permanent storage is displayed. Let go of the buttons and wait for the ready message on the display.

if this does not work contact hp, if within 2 years from the purchase date ask for a case number to have the printer serviced under a service note.

Your Line Interface Unit (L.I.U.) is bad. The part # is C9138-60001. Google for part availability.
1 Open or remove the left side door.
2 Remove one screw at the left of the formatter board.
3 Disconnect the flat flexible cable from the connector.
4 Rotate the LIU around the hooks to remove.

It's about a 5 min job. Good Luck.
