Hi @cactusreder,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I came across your post and want to assist you. I understand you are having print quality issues while printing from your HP Envy printer. Don't worry as I have a few suggestions which should help you resolve this issue.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Have you tried for any ink smears on the back of the print outs?

Have you tried to clean the electrical contacts?

Are you able to make a copy from the printer?

In the meantime, let's try these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the copy comes out bad, then I would suggest here is to follow the steps suggested in the support document for - HP DeskJet, ENVY, OfficeJet Printers - Black Ink Not Printing and other Print Quality Issues

If the copy comes out fine, I would suggest you to go ahead and uninstall and reinstall the printer software.

First, unplug the USB cable from the printer if present.

Go to Control panel – Programs and feature – Select all the HP Envy printer entries and uninstall them.

Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.

Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.

Under print server properties, go to drivers - remove any entry there as well.

Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

Restart your computer.

Now click on this link: http://ftp.hp.com/pub/softlib/software13/printers/EN5660/EN5660_Full_WebPack_40.11.1135.exe to download and install the printer software.

Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

Thank you for your response.

I followed your guidelines and nothing has changed.

The copy came out the same as printed pages prior.

Light and dark lines, usually alternating, with no ink on reverse side. 

Cartridges were cleaned (electrodes also ).

This printer is still under warranty.
