Question about HP PSC 750 All-In-One InkJet Printer

1 Answer

HP PSC 750 All-in-one Printer seems to be "dead". A recent power blip shut down some...but not all...electronic devices connected to my PC very briefly. (The PC itself appears not to have been affected.) All indicator lights are 'off' on the PSC 750, pressing the 'on' button does nothing. I've unplugged and re-plugged the power cable and USB cable on the back of the unit, and still nothing. Is there a simple way to determine if this machine is really toast and ready for the scrap pile, or is it perhaps in a coma and there is a "re-awakening" solution? Thanks.

    Sorry for the time lapse; I've been indisposed for a couple weeks (medical issue).
    My investigation reveals no capped/uncapped fuse holder anywhere on this machine. The (sealed) control panel module on top is removable, albeit connected by a ribbon cable to the interior. But there is no access to the machine's guts screws, no tabs, no clips, nothing. No way for the amateur to open it; must take it to a service tech (for a minimum charge, which at this point is probably equal to the value of the printer; it's 8 years old).
    Any other suggestions before I "decommission" it? Thanks.

Most of the printers might be equipped with a power surge protection fuse. But it may present within your printer and may be hard for you to reach it but a service person can. So take a look around your printer and if you can find any small red capped fuse holder like thing, then check for worn out fuse and if so, replace it to bring back your printer to life.

If you are not all hearing or seeing any notification when your printer is powered up, then its obvious that the power unit inside your printer got fried due to electric surge and in this case, its better to make a hardware service call to authorised printer service center. Claim it under warranty if still your printer has one.

All the best

Printer always says "Remove and check color cartridge"

It must be your ruined catridge. Some times the wire connections are burned at the side of the catridge and you must thaw away it and buy a new color catridge.
