Error message "50 service" showing in message window. What does this mean, and where can I get service?

A 50.4 code is bad line voltage. Don't plug it in a surge protector.
Any other 50 error is a fuser problem. Turn the printer off for at least 10 minutes. Power it back on. If the error returns, replace the fuser.

'EE' means cuff is underinflating. Re wrap cuff with varying amounts of pressure and restart [wait 2 minutes between readings].

Down load the user manual. from my memory its got the codes in it.

Machine Error 50 either means that there is a loose object inside the machine (usually piece of paper), or that there is a mechanical error which would need you to have the machine sent to service.

If it says to service it, then it needs servicing.

If your pc is showing a error before starting windows it means your system is corrupt or damaged. This can be fixed with chkdsk or a repair windows install or a clean windows install.

That is something you cant prevent from showing. It will always come up when there is a problem with the operateing system.

Hello,

 

Please try below solution.

 

ERROR 50 - Service

A 50 service error can be either a temporary error or a permanent problem requiring service.

 

Temporary Error: Power off for 20 minutes to allow the capacitor on the DC controller to fully discharge. If you don't allow this capacitor to discharge, you will still get a Error 50 even if you have fixed the problem.  This may clear the error - either temporarily or permanently. If it clears the error it was most likely caused by a low power problem  i.e. low line voltage causing the power supply circuits to drop out of regulation. Low/unstable power (low line voltage, brownout condition).  If it doesn't clear the error you may have one of the problems listed below

 

On the HP LaserJet 4L/4ML, errors are indicated by a series of indicator lights.  This printer has four lights, Paper Jam, Paper Out, Data, and Online.

 

If all four lights are on, press and hold the blue panel button to display a secondary light pattern.

 

An error 50 is indicated by the ready and error lights with the blue panel button pressed.

Turn the printer off for 15 minutes to see if the error clears.  If not, you will need to remove the fuser assembly to perform further checks.  This requires removal of the cover, an unpleasant task, and measurement of the fuser terminals.

 

Note: THERE ARE FURTHER STEPS TO CHECK THE ISSUE, HOWEVER IT IS NOT RECOMMENED TO CHECK USING YOU  ARE A USER, FURTHER STEPS NEED TO BE DONE ONLY IF YOU ARE COMFORTABLE AND INVOLVES MECHNICAL ISSUES OF PRINTER.

5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!

HI,my fax machine couldn't send and receive messages.it shows me an error code that read as 0552H call service....what does it mean..? please help me.

The fuser unit could be the causes. But you can try this, power off the printer & unplug the power cord for 15 to 20 minutes. Power on after 20 minutes and se whether the problem resolves, if it ok, monitor it for a while just to make sure the problem resolves
