Question about HP Photosmart 7450 InkJet Printer

1 Answer

The cartridge is stopped by a protruding piece of plastic.

Hello,

I'm in the process of taking off the cover of my 7450 photosmart HP printer. All the visible screws are off but there is some resistance left. Are there any manuals available to give me a 3d view of my printer like in the automobile manuals? Thank you for your time.

I took mine apart today, there's a silver cover on the left that needs to come off to access the final screw, and I can see of no way of separating the two halves, as there's a tab that protrudes down from the cover which connects with the bottom half. I ended up levering it off. This gives access to the panel and button circuit that unclips and unplugs, then undo the last screw, then there is a clip that needs to be held back to get the top cover off.

Hope this helps,

Paul.

My hp Photosmart 7450 printer was working, then in the middle of printing it stopped and there is an error message on my computer, the green light is blinking on printer but won't print


First things first... try connecting your printer to another pc or laptop and try printing... make sure spooling is on in the driver and there are no other programs running...

if issue reappears then

It sounds like your printer cartridges are the issue

I would try reinstalling them...

if that does not work then

I would try cleaning your printer cartridge...

Gather cleaning supplies:
Clean distilled water. Use bottled or filtered water if distilled water is not available.
Clean cotton swabs or any soft, lint-free material (coffee filters work well).
Remove both cartridges.
Unplug the printer.
Lightly moisten the lint-free cleaning material with clean water.
Clean the cartridge contacts. Avoid touching the nozzles. Replace the cleaning material if it gets dirty.

If that does not work then I would try ordering some new cartridges

I have HP Photosmart 7450 printer and want to install on HP pavalion a620n computer. I downloaded the driver for Windows 7 system. Still I cannot install the printer. Please HELP.


Please describe more about your problem. If you've downloaded the drivers, have you installed them? That is, have you run the setup program for installing the HP7450 on the HP Pavilion computer? When you run the setup program, part of the process will search for the HP7450. Are you connecting with the USB cable and have you check that it is securely seated in both the computer and printer? Is your printer turned on so the computer can find it during the search process?

HP Photosmart 7450


Most printers have a photosensor on the head assembly and the assembly (as it moves back and forth) rides on a strip of plastic that is dark with clear spots. That is how the cpu in the printer knows where (left to right) the head asm is located. So, If that strip is broken, or dirty or if the sensor is dirty this can happen. The sensor could also be defective. Try using some canned air to GENTLY blow away any paper residue in that area and then reset the power to the printer. If that doesn't help, then the printer needs serviced.

Hope that helps...

HP Photosmart 7450 stuck cartridge


not a solution, my paper feeds past the point where printer5.gif would normally begin. Then flashing light changes from green to red and print operation stops. Printer cartridge1.gif appears to be stuck in far right area of cartridge track.

Replaced drivers as above and still have the same problem.
Mine started after I had replaced the color cartridge. Mailed the old one to HP already so can't put in old cartridge.

If I unplug printer from computer, I get same results. Does the driver software install in the printer?
