OfficeJet 4630 won't power on... cover switch not working?

[PhillyDude]

I have checked the power supply and it lights up fine, but the printer won't turn on. Noticed there is no "tension" on a button (switch?) that would be activated when the ink bay / jam clear door is closed... it just flops around. Is trhis indeed a "safety" switch that would prevent power from being turned on when the unit is open, and if so, how do I access it to check and/or replace?

Hey there! @PhillyDude, Thanks for stopping by the HP Support Forums!

I understand you have issues power on the printer.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

I understand your concern and situation you are into. Also, I appreciate your efforts for trying out few steps before reaching out to us.

Also, as the parts on an HP printer are non-customer accessible. You have to contact HP and get a replacement printer. 

Try the steps recommended below.

Restarting the printer might resolve any connectivity error states.
Turn the printer on, if it is not already on.
Wait until the printer is idle and silent before you continue.
With the printer turned on, disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
   NOTE:
HP recommends connecting the printer power cord directly to the wall outlet.
Reconnect the power cord to the rear of the printer.
Turn on the printer, if it does not automatically turn on.
The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
