How to fix a printer that don't power up

It's a little late now but in the future you always want to bring your engine up to top deaf center before disassemblying

That printer is fubar and needs to be junked. And don't bother asking HP to help you because they only help during warranty period. Otherwise they refer you to a forum or suggest you buy another printer - an HP of course.

hi,

seems your cpu fan is damaged .

i suggested to contact an expert technician to repair the necessary damaged devices.

pay attention : don,t turn on your hp till refer to said technician.

The printer may be faulty. I suggest you return it to the supplier to have it fixed or replaced under warranty. If you try to fix it yourself you may void your warranty.

Hi,

This is an indication of out-of-regulation in the power supply section. This is cause by leaky/dried electrolytic capacitor in that section. It will dropped the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst until the unit will not even power up. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky/dried capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

You may need to reset the OfficeJet 4255:

1) With the power on, disconnect the USB cable
2) Follow the recommended procedure in your manual to remove the ink cartridges
3) Wait for the "Insert cartridges" message
4) Unplug the machine for 1 minute
5) Reconnect the power cord (press power button if necessary) to power on the unit
6) Reinstall the cartridges, close any access doors
7) Allow the machine to print a calibration page (if necessary)
8) Reconnect the USB cable
Try printing again.

If this procedure fails, your OfficeJet may need servicing by a qualified tech.

Try simply turning off the printer, disconnect from power, and let sit 5 minutes. This will bleed out the printer's internal memory. Reconnect and try again. Otherwise, if you can't get the reset procedure to work, unfotunately, these printer have an integrated printhead system, and the printer will need to be replaced.

the answer is dependent on the printer model, OS, connection(cable wireless, local, network)
please supply more information

in a HP-PSC-1210, replaced empty HP56 black-inkjet cartridge.
Afterward, printer gave error message AND unable to "dismount" the cartridge.
Finally discovered that an HP57 color-inkjet cartridge had accidentally been mounted/installed. A handyman relative was able to dismount the (wrong) cartridge.

Cradle did not actually jam, though printer would not print.
