Likely one of these components has sustained some damage from the impact. The heating element inside the fuser assembly is porcelain and will crack easily. Cooling fan is stuck from damaged or misaligned fin, or the laser scanner assembly isn't spinning up properly. Any of these components can fail and the printer still seems like it's about to print but stops.
Better to have FULL 'make model' and the Service Tag Number, but it appears to be a well documented issue.

5. Remove the new print cartridge from its packaging, remove the orange cover from the print cartridge, and then pull the orange tab straight out to remove the sealing tape.

Raja Ahkter is definitely a AI Bot. There was an answer from him earlier for a Washing machine where here suggested checking the 'Compressor', (thinks it is a fridge) and then a bit further on in the same answer suggested also checking the Inlet and Exhaust valves (thinks it is a car)! I delete his answers, but the bot picks them back up and answers again.

To enlarge the print when copying on the HP Envy 4500, you can adjust the zoom or scaling settings in the printer software. Here are the steps to follow:
1. Load the document or photo that you want to copy onto the scanner bed.
2. On the printer control panel, press the Copy button.
3. Use the arrow buttons to navigate to the Zoom or Scaling option and press OK.
4. Use the arrow buttons to select the percentage by which you want to enlarge the print. You may be able to choose from a list of preset options (such as 125%, 150%, or 200%), or you may be able to enter a custom percentage.
5. Press OK to apply the changes and start the copy job.
If you're using the printer software on your computer to control the copy job, you may need to follow slightly different steps depending on your operating system and the version of the software you're using. However, the basic process should be similar. Look for options related to zoom, scaling, or print size, and adjust the settings as needed to achieve the desired level of enlargement.
