Nothing but problems with HP Color LaserJet Pro 4201/4301 series: freezes, unstable ping in sleep, e

[PaperITGuy]

Ever since our company got these new versions we've had nothing but problems. We have 4 HP Color LaserJet Pro 4201 and 1 4301. 

1. Freezes in sleep mode: 1 4201 and the 4301 after they are asleep for awhile will drop their network connection. If you try to use the knob for the 4201 or console for the 4301, they will be frozen. You have to hard power off the devices. Auto-shutdown is off, firmware is current.
2. Absurdly unstable network ping/connection in sleep: The network stability/ping on these terrible. I've confirmed the moment they go into sleep, they change from 1ms response to the below: 
   
   
   

   When I called to do a case for the first one that was freezing after being idle for awhile and mentioned the high ping, the 1st level actually had the gall to say "that's just how these new printers function". We have a fleet of 80 some HP printers of like 10-15 different models; NONE of them do this, nor do the computers next to them.  No way in hell that's how printers are supposed to run/ping.

I've seen a lot of complaints about these new models and concerned that there hasn't been a firmware update to try and fix any of the listed issues since Jan, over 7 months ago.

We’re always glad to assist — thanks for reaching out to the HP Community.

Thank you for bringing this to our attention, and I completely understand your frustration—this is not the experience we want you to have with your HP Color LaserJet Pro devices.

We appreciate the detailed observations you’ve shared regarding the freezing and unstable network behavior during sleep mode on your 4201 and 4301 printers. Based on the information provided, your devices are already running the latest firmware, and Auto-Shutdown is disabled, so you’ve done all the right steps so far.

At this stage, we’d like to gather additional logs and configuration details to escalate this to our engineering team for deeper analysis. Please send us a private message along with the product serial number and your contact details.

We’ve also forwarded feedback internally regarding the long gap between firmware releases for these models. Our teams are aware of user reports about sleep and connectivity stability, and this information will further assist them in prioritizing a fix.

We truly value your continued partnership and patience as we work to identify and resolve this issue.
