Sprocket Printer giving strange error message: "Sprocket is cold"

[question_asker]

My HP Sprocket Portable Printer x7n07a is giving a strange error message.  It is saying it is "cold" and that I'll need to wait and print from the queue later.  The exact error message is "Sprocket is cold."

I connect via my iPhone.

Hi @question_asker.

I'd like to help!

Allow the Sprocket a few minutes to cool down between print jobs. When the Sprocket becomes too warm, a cooling down message might display on the HP sprocket app. Allow the Sprocket to cool, and then tap OK to clear the message.

Upgrade the Sprocket firmware

HP regularly releases firmware updates. Upgrading the Sprocket firmware might resolve the issue.

1. Make sure the Sprocket is on and your mobile device is connected to the Internet.

2. On your mobile device, open the HP sprocket app.

3. Tap the Menu icon , and then tap sprocket.

4. Tap Manage Printers, make sure your Sprocket is selected, and then tap Printer Settings.

5. Look for a firmware upgrade.

   • If a firmware upgrade displays, tap Get Firmware Upgrade, and then follow the on-screen prompts to complete the update.

   • If a firmware upgrade option does not display, the firmware is up-to-date.

Hope this helps! Keep me posted.

I think you might have misinterpreted what I was saying.  You gave me instructions for letting the Sprocket cool down.  But mine does not need to cool down.  It's the opposite -- mine is saying it's TOO COLD (read the subject line of my message).  I've searched for this error message on the internet and found nothing.

I did follow the steps you provided to check if the firmware needed upgrading.  It did not.  It is all up-to-date.

Have you tried charge the sprocket , does the charging light tun on?

[question_asker]

Yes, I have had no trouble charging the device.  The light turns on and reports that it's charged in the phone app.

Reset the printer -

• Reset the printer. On the printer, locate the pin-hole near the charging port, insert a straight pin into the hole to press the reset button until the printer turns off. Restart the printer.

Keep me posted!

I tried resetting the sprocket printer.  I inserted the pin and waited for the printer to turn off.  I turned it back on and it said something like "Your HP sprocket printer will print now."  However, then it reverted right back to the previous error message I mentioned and said "Sprocket is cold."
