How to change a fuse in the hp 2800 printer

The system will not totally power up. It shows the hp emblem on the little screen, but when you press the power button, nothing happens. is the fuse the problem. I think this happened when we had a power surge while printing and lost power. Mike

There are 2 fuses inside the power supply unit.

The hard part is getting to the power supply! The power supply is located at the left side of the printer and in the front (the opposite side of the cartridges).
You have to remove the side and top covers.
There are some hidden screws. One is under the button faceplate that you will also have to remove. The entire procedure is tricky especially without a service manual. Unfortunately I couldn’t locate a manual.
Caution always disconnect the power lines and allow some time for capacitors discharge before you attempt any repairs.
I hope you have some luck with yours !!

There are no end of problems with HP printer driver software. I've had them too. The most likely success will come from completely UNINSTALLING the present HP printer software (ALL OF IT) and reinstalling the MOST CURRENT PRINTER DRIVER for your computer operating system. You download that driver from by inserting your model number an following the screen instructions. There is a companion PRINTER DOCTOR tool from HP that you should also download just in case you continue to have a problem after you install the new driver. I can't stress to much how important it is to completely remove all traces of the HP software from your computer first before you reinstall using the latest driver. Failure to do so will cause you continued problems.

Also, if you want to minimize other software issues, after you've downloaded the most recent driver, REMOVE your Antivirus Program if you are using one. I found that there were conflicts caused by Kaspersky AV firewall settings that HP software did not over come. I reinstalled Kaspersky AV after the HP software install and everything worked fine then. The necessity of this step seems to be computer-dependent. I have 3 pcs, all running Win10 Home and only ONE of them required this extreme step in order to get the software to function completely ok.

Hp Business Inkjet 2800 printer prompted me to change the cyan printhead. I changed the cyan printhead and it is not detecting the new printhead. A printer repairman came to inspect the printer and...


Did you check the connections in the carriage if there is little amount of ink on the contacts? if not then clean it well with a dump cloth and try to re-install the old printhead it will sure accept it. If not then the other way is to change system date of the printer first and then try again.

Is there a cmos battery in an hp 2800? If so, where is it?

There is no CMOS battery in this printer. The instruction manual indicates the only way to reset the printer is to power it off, unplug it, and let it rest for 30 seconds before reconnecting power and turning it back on.

Looks like it is out of ink but after buying new cartridges, it still does not print correctly


The first thing that I would advise you to do is,

Put of the printer,

Uninstall the Printer Software totally from the System first,

Restart your computer,

DO NOT connect the printer yet.

Re-install the HP Printer software that came with it.

If you don't have it again the you can easily download it from HP Website in the support section.

Wait until it reaches the stage where you are asked to plug in your printer.

Then Locate a USB 2.0 Port on your computer, but make sure it is not the port that you normally use to connect the printer to your system before.

Plug it in and let it do the rest.

Try this out and let me know how it goes.

Hope this helps.

Good luck

Try This:
cold reset on the printer with only the power cable connected. By doing so, the printer settings will default to factory settings. Please note that after a cold reset the printer settings will default to factory settings and you may have to re-configure all the settings.

Press and hold the Return and Select buttons, then press Power button to turn on the printer.

Rollers should be available; you replace the whole roller, not just the rubbers.

This is a common problem. If you've checked the side guides, change the rollers, but this type of problem is sometimes uncorrectable. Some printers just don't like some paper.
