Only 3 free month trial instead of 4 for 8210 printer

[Zihong]

I bought 8210 printer from amazon (https://www.amazon.com/dp/B01HSADJIO?psc=1&ref=ppx_yo2ov_dt_b_product_details) which says I should have 4 months free trial on instant ink but when I enroll, I only receive 3 month (by entering the serial number in hp account adding printer product).

Another issue is that the printer cannot go to sleep. I set the sleep time to 5 minutes. When it goes to sleep, the screen turns off but immediately recovers.

Thank you.

I successfully redeem the free trail. No worries.

But the sleeping issue remains to be a problem.

Hi @Zihong,

Welcome to the HP Support Community

I understand you are facing a sleep mode issue with your HP OfficeJet Pro 8210 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
