My HP Smart Tank Plus 551 Won't Wake Up

[TickedTexan]

I see that this topic first came up in 2019.  Here I am in 2022 and evidently the problem has not been solved.  I have installed the latest driver but my Smart Tank Plus 551 printer will not wake up.  I have unplugged and restarted four times now and it won't budge.  It's maddening.

Please tell me how to fix it that won't take me a couple hours.  This is HP's problem, not mine.  You should make a better, consistently reliable product or tell me where I can return it for a full and immediate refund.

Hi @TickedTexan,

Welcome to the HP Support Community

I understand you are facing a sleep mode issue with your HP Smart Tank Plus 551 Wireless All-in-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

 Let's perform a power drain: 

• 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 warm-up period finishes and the printer is idle
