HP OfficeJet 7310 printing crooked. New HP cart installed.

check the paper tray, make sure the paper guides are snug up to the edges of the paper. Even a small gap will cause miss alignment of the printing.

the carriage jam error is meaning the path that the printhead is sliding from side to side. You might have a small piece of paper causing an issue.

Here are the instructions for resolving a carriage jam (and a paper jam) on the Officejet 7310.

You must replace all ink carts with GENUINE HP carts to get a sucessful alignment.

Hi,

1. Press the Setup button.

1. Use the arrow keys to select Tools and then press the OK button.
2. Select Clean Print Cartridge and then press OK . The device prints a test page.
3. Examine the test page. If the print quality of the page is good, stop here. If the print quality is bad, go on to the next step for further cleaning.
4. Open the Printer Toolbox . There are two ways to do this:
   • Open HP Director , select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox .
   • If the HP Director method does not work, open Printers and Faxes in the Windows Control Panel , then right-click your printer icon and choose Properties . Click on Printing Preferences . Click the Services tab, then the Service This Device icon.
5. The Printer Toolbox opens. On the Device Services tab, click Clean the Print Cartridges , then follow the on-screen instructions. Up to three levels of cleaning are available. Discard or recycle the page that prints.
6. Remove and re-insert, while the product is switched on.

If still bad, swap out the cartridge.

Hope this helps
Regards

The back of the unit has a piece which pulls off to clear paper jams. It was not fully pushed in. I found the solution on another post that was on your site.

Sounds like the print head / ink cartridge is not seated all the way. Open the door and check it. It also may be the wrong print head / ink cartridge. If you replaced the print head / ink cartridge recently, you may have the wrong one for your device. If it is a off brand or refilled print head / ink cartridge it may be damaged or incorrectly identified.

most printers are pretty cheap now so replacement is always an option....on the other hand, I will spend countless hours trying to figure out what is wrong first. Remove all paper first, open printer and check for pieces of torn paper or debris, if you have a can of air you can blow out the insides to clean. Put 3 or 4 sheets of paper in, print a test page and watch carefully how paper advances...is it straight or crooked when being loaded? Is printer trying to pull more than 1 sheet at a time? Good luck

please check gear train and confirm no broken one-check of selonid not working in a right way and no foreign object droped inside(like pins).-check of smoth actuation of paper present detector.(in place and movement when you put papers
