Hi. My HP OfficeJet 4620 has started printing blank pages and i know the ink cartridges are ok.

[Vtopmiller]

I have turned my printer off and unplugged it.  Left it off overnight.  I put some water on the ‘head’ for the black ink and then it printed faintly.  I put a color page on glass and nothing printed.  Not even faintly.  I know the ink cartridges are full.  We only occassionally use this when we are at this residence about 6 mos a year. 

Thanks for help!

@Vtopmiller The ink could have dried out as it's suggested that the printer is used or at least turned on every day for the ink to be functioning,

that said, If you've ensured genuine/compatible ink cartridges are being used, please try the below steps:

Step one: Print the report

1. Load plain white U.S. letter or A4 size paper in the tray.

2. On the control panel home screen, press the Setup icon .

3. Press the button  next to the Down Arrow  until Reports displays next to OK.

4. Press the button next to OK to select Reports.

5. Press the button next to the Down Arrow  until Print Quality Report displays next to OK, and then press the button next to OK. The report prints.

Also, check if the copier works as a stand-alone device:

If it works fine, this could be a software issue with the printer drivers,

If that doesn't work either, send a picture of the print diagnostic page or let me know if that's blank as well.

Keep us posted,

Hi, Riddle.  I am so new to this.  Thank you for replying.  I did what you said.  It printed and all that was there were some black, bold lines in the middle of the paper.  Here’s what printed.   I cleaned the printer heads with alcohol.  I watched a video and did what ‘Brandon’ instructed.  I didnt take printerhead out.  Just cleaned where ink goes in and let it dry overnight.  I tried new black ink even so it is that.   Is it hopeless?  I’m willing to try any procedure since right now the printer is useless.  Thank you SO much! What prints.

@Vtopmiller To confirm, the copier works the same as your printer? if yes, here are a few things I suggest you do:
(To try everything possible before we can conclude it's a hardware malfunction)

If the vent on the top of the cartridge is clogged or obstructed, the cartridge might not work properly. Follow these steps to make sure that the cartridges are properly vented and seated correctly.

1. Press the Power button to turn on the printer, if it is not already turned on. Wait until the printer is idle and silent before you continue.

2. Locate the two slots on the left and right sides of the printer.

   Figure : Locations of the two slots

   

3. Slide your fingers into the two slots, and then lift up to open the cartridge access door. The carriage moves into the access area.

   Figure : Open the cartridge access door

   

4. Press the tab on the front of the cartridge inward to release it, and then pull up on the cartridge to remove it from the slot.

   Figure : Remove the ink cartridge from its slot

   

5. Locate the vent area on the top of the cartridge.

   Figure : Vent area on the top of the cartridge

   

6. If the cartridge still has the orange pull-tab attached, pull to remove it.

   Figure : Orange pull tab

   

7. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

   Figure : Clean the clogged vent with a pin

   1. Clogged vent

   2. With a straight pin, gently remove excess adhesive from the vent

   3. Unclogged vent

8. With the nozzle and contacts facing down, slide the cartridge into its slot. Press down on the cartridge until it clicks into place.

   NOTE: 

   Make sure that each cartridge is installed in the correct slot. Match the shape of the icon and the color of the cartridge with the slot that has the same shaped icon and color.

   Figure : Reinsert the cartridge

   

9. Repeat these steps to inspect the vents on each of the cartridges.

10. Make sure that each cartridge is firmly in place in its slot. Run your finger along the top of the cartridges to feel for any that are protruding, and if any are, press down firmly until each cartridge snaps into place.

11. Close the cartridge access door.

    Figure : Close the cartridge access door

    

12. Print, and then review another test page.

• If these steps resolved the issue, there is no need to continue troubleshooting.

• If the issue persists, see the next step.

Step four: Use an automated tool to clean the printhead

Follow these steps to run an automated tool to clean the printhead.

   CAUTION: 

Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.

1. Load plain, white U.S. letter or A4 size paper in the input tray.

2. On the printer control panel, press the Setup icon .

3. Press the button  next to the arrow  until Tools displays next to OK.

4. Press the button next to OK to select Tools, and then press the button next to the arrow  until Clean Printhead displays next to OK.

5. Press the button next to OK to clean the printheads.

   The printer cleans the printheads and then prints a test page.

6. Evaluate the test page for print quality.

   Figure : Example of the printhead cleaning test page

   

   • If the print quality on the test page is satisfactory, touch No to return to the current print job.

   • If the print quality on the test page is unsatisfactory, touch Yes to perform a secondary cleaning of the printhead.

     There are three printhead cleaning stages. Complete all three stages if necessary. If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last (third) cleaning stage to start the first stage of the cleaning

     Step five: Update the printer firmware

     If cleaning the printhead fixed the problem, select the link for your printer to install the latest firmware update. The firmware update can prevent future printing problems.

     NOTE: 

     Currently, firmware updates are only available for Windows operating systems.

   • Select your printer:

     • HP Officejet 4610 All-in-One Printer

     • HP Officejet 4620 e-All-in-One Printer

     • HP Officejet 4622 e-All-in-One Printer

     • HP Deskjet Ink Advantage 4615 All-in-One Printer

     • HP Deskjet Ink Advantage 4625 e-All-in-One Printer

   • Follow the on-screen instructions to download and install the firmware update for your printer.

   • If you do not see defects on the test page, the print mechanism and cartridges work correctly. Do not continue the troubleshooting steps in this document.

   • If you see defects on the test page, try the second-stage cleaning option the printer offers. If you still see defects on the test page, continue to the next step.

   • Step six: Align the printer

     Follow these steps to align the printer if you found defects on the test report.

   • Make sure that there is plain white U.S. letter or A4 size paper in the tray.

   • On the printer control panel, press the Setup icon .

   • Press the button  next to the Down Arrow  until Tools displays next to OK.

   • Press the button next to OK to select Tools, and then press the button next to the Down Arrow  until Align Printhead displays next to OK.

   • Press the button next to OK to align the printhead. The printer aligns the printhead, and then prints an alignment page.

   • Lift the scanner lid.

     Figure : Lift the scanner lid

     

   • Load the alignment page print-side down in the right-front corner of the glass.

     Figure : Load the alignment page on the scanner glass

     

   • Press the button next to OK. The printer scans the alignment page.

   • process over again.

If the issue persists, replace both cartridges and if that doesn't do the trick, I'm afraid we are all out of options, hence we'll need to consider getting the printer repaired/replaced,
