Question about HP Photosmart 7450 InkJet Printer

1 Answer

HP Photosmart 7450

I have my printer unplugged from the computer and the following happens
just like previous customer:
Paper feeds past the point where printer would normally begin. Then flashing light changes from green to red and print operation stops.
Printer cartridge appears to be stuck in far right area of
cartridge track. Nothing appears to be preventing cartridge movement, however it appears to be locked into place.

Have installed drivers from HP while is was connected to pc, still does same thing.

thanks

    Lights are working on the photosensors and I cleaned the strip. I can get one page to print, cartridge will move to right, a cleaner comes out under cartridge and cleans, then a page gets positioned an inch past the cartridge and printer stops with red light flashing. A page should not even be moving to a position since I only want to print one page.



    thanks

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...

Printer won't print. Flashing red light. No paper jam and ink cartridges are ok. Please help!!


Per the manual, it's 99.9 % one of these causing the issue. The other .1 % should take it back or get a new one.

The printer requires attention. Try the following:
● If the printer is connected to a computer, check the computer screen for
instructions. If the printer is not connected to a computer, check for the following
problems:
– Top cover open
– Out of paper
– Paper jam
– Print carriage jammed or stuck
– Print cartridge inserted incorrectly
– Incorrect print cartridge installed
● If you are unable to solve the problem by using the instructions above, turn off the
printer and unplug the printer's power cord. Wait one minute, then plug it in again.
Turn on the printer.

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?

Paper jam light is on


Hi! I have the same issue. The only solution I still use: select print from document with no paper in the hp's feeder. Let the printer go on "paper out" message, now put the paper into the feeder and press the print button on the printer. Success!
