View Full Version : Printer turns on and off by itself.

My H P Deskjet 600 printer, when switched on at the wall, has recently started switching itself on and off at periodic intervals. I now leave the wall switch off, but it is annoying when the printer turns itself off in the middle of printing a document. Otherwise it is working just fine.

Is it likely to be a simple switch fault, or more likely to be the circuit card?Has anyone else experienced a similar thing? Any suggestions welcome.

Make sure the power cord is inserted snugly into the back of the printer. If the printer is on a desk that is not stable, it can wobble a lot, and thus wiggle the cord loose out of the back.

Sorry I can't help you, but have had the same problem with my HP 690C. After about a month of switching on or off in the middle of the night, or any other time, it suddenly righted itself. A loose connection will switch it off, but not on. It is annoying, so hope yours comes right too.

Be aware that anything inhibiting free carriage travel will cause the printer to turn off, as a protective measure. Make sure the printhead is free and unobstructed, no gunk or corrosion on the axis bar.

An insecure connection may just turn something on when it connects too...
