the scanner endlessly fails to read the sheet

HP Recommended
HP Envy 4500
Microsoft Windows 10 (64-bit)

After replacing the ink cartridge the printer restarts printing an alignment scan sheet. When I place the sheet in the scanner the scanner endlessly fails to read the sheet. The Scan Doctor fails also fails to complete.

Hi @Jc1313,

 

I'd like to help!

Try the below suggestions -

 

Step 1: Complete the alignment process again

Print a new alignment page.

  1. Load plain white paper in the input tray.

  2. Adjust the paper width guides until they rest against the edges of the paper.

  3. Print an alignment page.

    • Control panel (printers with menus): Open the Tools or Printer Maintenance menu, and then select the option to Align cartridges, Align printhead, or Print an Alignment Page.

    • HP Smart app (Windows 10, macOS, Android, iOS): In the app, click your printer, click Print Quality Tools, and then select the option to align the printheads or cartridges.

    • HP Printer Assistant (Windows): Click Maintain Your Printer, and then select the option to align the printheads or cartridges.

    • HP Utility (Mac): Click the option to align the printheads or cartridges.

  4. If your printer has a scanner, follow the directions on the alignment page to scan it and complete the alignment.

If these tips do not resolve the error, continue to the next step.

Step 2: Reset the printer

Turning the printer off, and then on again might resolve an Alignment failed error message.

  1. With the printer turned on, disconnect the power cord from the printer.

  2. Unplug the power cord from the power source.

  3. Wait 60 seconds.

  4. Reconnect the power cord to a wall outlet and to the printer.

    NOTE: 

    HP recommends plugging the printer directly into a wall outlet.

Step 3: Clean the printhead or ink cartridge

Use a printhead or cartridge cleaning tool to help prevent streaks, smudges, or lines that can interfere with the alignment process.

  • Control panel (printers with menus): From the Settings, Setup, or Tools menu, look for an option to clean the printheads or cartridges.

  • HP Smart app (Windows 10, macOS, Android, iOS): In the app, click your printer, click Print Quality Tools, and then select the option to clean the printheads or cartridges.

  • HP Printer Assistant (Windows): Click Maintain Your Printer, and then select the option to clean the printheads or cartridges.

  • HP Utility (Mac): Click the option to clean the printheads or cartridges.

After the cleaning, evaluate the page that prints. You might need to clean the printheads or cartridges more than once.

If cleaning the printhead does not resolve the issue, continue to the next step.

 

Step 4: Check for and replace faulty printheads or cartridges

Alignment pages with defects or missing colors can cause the sensor inside the printer to misread the page and alignment to fail. Check the page for issues, and then replace any faulty printheads.

  1. Check the page for defects such as missing colors or sections. See the examples below for sections of alignment pages without defects.

    NOTE: 

    Depending on your printer, the alignment page might have multiple colors or only black ink. Most alignment pages include a series of lines and blocks.

    Examples of alignment pages without defects

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

 

Also, check if the scanner bar up and if it moves.

 

Hope this helps! Keep me posted.
