Inconsistent print results

[SharonMcK1]

The printer prints one page perfectly.  The next page is perfect in the top half and the bottom is blank.  The following page has lines running vertically down the page.  And all have inconsistent color, sometimes predominantly one color.  And each print produces different resuits.  I've changed printer cartridges, and it doesn't help.  I've searched the web and can't find anyone withj a similar problem.  Has anyone had this problem?  Is it a warranty problem or a cartridge problem?  I bought the printer through Amazon; where can I get it repaired?

Hey there! @SharonMcK1, Welcome to HP forums.

I understand you have print quality issues while printing from your printer.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Have you tried printing using a different brand paper?

Have you tried printing with a different ink cartridge?

Have you tried printing using a different application?

As you mentioned when you print from your printer the page one prints fine but the page two prints only half and rest is blank.

Replace low or empty ink cartridges on your printer.

Try few steps recommended below.

Check the print settings for your print job in Windows.

1. In the software application you are trying to print from, click File, and then click Print.

   The Print window opens.

2. Open the Properties dialog box.

   Depending on the software application, the button might be Properties, Options, Printer Setup, Printer, or Preferences.

3. Depending on your print job, you might consider modifying the following settings:

   • Paper Type: If you are printing on photo paper, select the type of photo paper you are attempting to print on.

   • Print Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality. These options typically include Best, Normal, and Draft modes.

   • Paper Size: If you are printing on a different size of paper than you normally print on, select the correct paper size.

   • Black and White: If you want to print in black and white only, select the grayscale option.

4. After selecting the print settings, click OK to apply the settings, and then click Print.

Also, If the copy works fine uninstall the printer software from root level on your PC and install the full feature printer software.

In Windows, search for and open Programs and Features.

Select your HP printer.

Select Uninstall.

In Windows, search for and open Devices and Printers.

In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

Open up the run command with the "Windows Key + R" key combo.

Type printui.exe /s and click OK.

Click on Drivers tab.

Look for HP Printer driver. If you see it click on it and click remove at the bottom.

Select OK.

Select Apply and OK on the Print Server Properties windows.

Close Devices and Printers.

Update the full feature printer software using this link: http://ftp.hp.com/pub/softlib/software13/printers/OJPRO7720/OJ7720_Full_WebPack_44.1.2550.exe

Thank you for your response.  I am sorry I have been slow to respond to you; it was due to back surgery this past week.  I will follow the detailed instructions you provided and determine whether they resolve the problems I continue to have and then follow up with a detailed description of the results for your review.

It looks like you were interacting with @A4Apollo, but he is out for the day & I'll be glad to help you out, 

I'm the Riddle_Decipher & I'm at your service. 

I hope the back surgery is successful & you recover quickly, might I suggest you check this treatment called the "hijama", works wonders for the back, on a personal account.

That said, please get some rest, take it easy and when you get some time, please reply back with the results and if the issue persists, we'll be happy to help you resolve this issue completely.

Let me know how that pans out

feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon,

followed by clicking on 'Accepted as Solution' as it would help the community gain more knowledge,

And Have a great day Ahead!

Riddle_Decipher, I've tried twice to respond to your post, and my messages are rejected.  I'll try it this way:

Okay, my husband and I read Mr. Robot's suggestions, but this problem is much more complicated than that.  We tried uninstalling and reinstalling the printer drivers and software multiple times. We reset the router over and over.  We changed all the ink cartridges multiple times.  We changed the paper to a different brand.  We've both shut down the printer entirely and let it go completely through its warm-up cycle countless times.  It sometimes acts like it's not getting the commands from the computer, but if we unplug it and plug it back in, sometimes it will print (for awhile) and sometimes not.  After it sits, it evidently goes into sleep mode, and neither one of us have figured out how to get it to respond to commands again.   It has to be turned off completely and restarted.  

Yesterday I tried to print out a 1040 form in color, double-sided.  After four tries, it printed the top third of the first page and the bottom half of the second page.  I tried again multiple times after that, but I could never get a complete print.  The color was actually fine for a change.  Two days ago I tried to print a post with a photo from Facebook at least a half dozen times.  When I finally got a complete print, the color was smeared, the color saturation is just a mess.  I'm using genuine HP ink cartridges, and it's costing a fortune when 19 out of 20 prints ends up in the trash.  

Please understand that this is essentially a new printer.  No more than 6,000 sheets of paper (that's probably a gross exaggeration) have gone through this printer since I bought it.   FYI, I have a big Dell desktop computer with an I-7 processor and  dual monitors.  It is installed with Windows 10 Home Edition and the Chrome browser.  I also have a super fancy-schmancy Lenovo 15" laptop with an I-7 processor, and it is installed with identical software.  And I'm having identical print problems with commands sent to the printer from it.  We have a wireless network, and we've done extensive troubleshooting on the network and can't come up with any problems there either, not one.  

I used to be able to sit downstairs and send a print command from my laptop without any problem.  For almost the entire last month, I can't get a satisfactory print out of the printer even sitting in front of the desktop computer that sits right next to the printer.  We're just beyond tearing our hair out.  There has to be something physically wrong with this printer, and I don't know how to get it repaired or replaced.  I bought it through Amazon, and it was delivered on December 24, 2017 (ORDER # 111-1670276-4824243) , and it's been out of commission now since the early part of March.  And I've had it now way too long to send it back.

I can't begin to tell you how disappointed I am.  I've had many HPs in the past -- both laser and inkjet -- and we've never had problems like this.  I'm just sitting here shaking my head.  If you still think this is a software problem (I really don't), can you provide a phone number for us to call [[so that we can talk directly with a tech over the phone?

RLM and SAM
