Good luck.

Thanks for using FixYa.

put a single paper at a time when u give a printing command. also use good quality papers. Adjust the size of the tray.

i hope this would resolve the problem

the moving ink frame is probably pointing to a symbol such as replace color ink( three dots on ink cartridge picture). Replace color ink. You are probably printing your black and white documents with colored ink--always select black or greyscale.

Try to turn off the printer, open the compartment and check the roller. try to pull the paper and at the same time flip the roller in such a way that the paper will move out. If it is jammed and crumpled like what I exactly experienced earlier, remove the paper as fast as you can.

Turn on the printer, wait for the inkjet devices in a neutral position. Then insert the paper and start printing again. If it didn't work, try to hold the tip of the paper in horizontal manner while printing and make sure you remove the entire paper before the next page prints itself...

Find another computer (laptop?) that is running Windows XP or Vista. Install the HP device-drivers.
Connect the printer to that other computer, and use the software to display the ink-levels.

ok if the printer is installed properly, what you have to do is: 1. go to start>printers and faxes. if your printer is installed it should be there (depends on your OS basic steps); if you see your printer in this folder, go ahead and right click on it, select "set as default" or "make default" and you would see a green check mark on your printer's icon, now you can close all of that. When you are ready to print, make sure that your printer is selected and go ahead and click print.

if it works for you, don't forget to rate me

Change ink cartridges, can be the hardware

The usb cable for your printer is the same for the PC, go to any store that sells usb cables and buy one. If you are near a wall mart or any travel store there are kits that you can buy with those adapters.

Hi Rustylobell,

I understand that you are facing some problem while printing to your printer. Please follow the below steps to resolve your problem.

1. There may be many number of reasons for your problem like this. So rather than digging upon the reason, we can reinstall the printer driver once again to rectify the problem.
2. By reinstalling the driver, all kinds of problem due to improper settings and driver conflicts may gets rectified.
3. So goto control panel and remove all the drivers and softwares associated with your printer.
4. use the driver cd which came along with your printer to reinstall back all the drivers and printer applications once again.
5. Go for a system restart and now try printing your documents again and everything should work fine.

Regarding the print command window which you are asking about, it is the window in which you can see all the print jobs being sent to the printer and is waiting in the queue to get printed. using this window, we can restart / delete / stop / pause the print job.

1. To get the print command window, goto start -> printers and faxes.
2. you can also go via control panel -> printers
3. In that window you can see the list of all installed printer. Select your HP inkjet printer model and double click it to get its print command window.

I hope this is helpful in solving your problem.

Hi,
If the ink level is low in a print cartridge, the Print Cartridge Status light stops flashing when the printer’s top cover is opened. When you open the panel the ink cartridges slide to the center , as far as checking the ink level find and right click on the printer icon, click properties, and find ink cartridges and ink levels.
Thanks
Shereena.

It may be not genuine or expired cartridge
