The correct answer is D. Unbox it and examine it for physical damage.
The first thing you should do when you receive a new printer is to unbox it and examine it for any physical damage. This includes checking for dents, scratches, or any other signs that the printer may have been damaged during shipping. If you find any damage, you should contact the manufacturer or the retailer where you purchased the printer to file a claim.
Once you have verified that the printer is not physically damaged, you can then attach it to a PC and print something to test its functionality. If the printer does not print correctly, you may need to troubleshoot the problem or contact the manufacturer for assistance.
A, B, and C are incorrect because they are not the first thing you should do when you receive a new printer. MSD diagnostics is a tool that can be used to diagnose problems with a computer, but it is not necessary to run this tool when you receive a new printer. Checking the cables is also a good idea, but it should be done after you have unboxed the printer and examined it for physical damage.
E is incorrect because it is not a valid option.
