0x6100004a is the error I keep getting.

There’s no jam, the cartridges won’t move, it keeps telling me I didn’t shut it off properly which is a lie. And it keeps giving me “0x6100004a” and telling me to contact Hp

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• 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 (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle.

Hope this helps! Keep me posted for further assistance.
