If you want help fixing your device or want me to do it please contact me.
With no drops, no overheating, 2 batteries in use and a lower power user the Wismec rX2/3 started throwing a Check Battery error. I did not have the proper hex bit to do the existing standard fixes so I came up with a new fix.
To test if this is the fix for you connect a piece of wire to the 2 points below with batteries in and attempt to fire the device. If the Check Battery error does not appear then this fix should work for you.
The new fix bypasses the cover connections. With that said the note that this fix has not been checked against using 3 batteries so use at your own risk. I apologize for not taking pictures during the repair so I have illustrated over pictures posted on the net by others. Credit for original images at end of post.
Solder a wire between the 2 points circled in yellow and shown connected in red. Beauty of this fix is that you can test without the back cover. Once the new wire was is in place I reassembled with everything working.
If you use this fix contact me and let me know how it turned out.
Try this at you’re own risk and understand I’m not responsible for anything that goes wrong.
I have an older HP LaserJet P2035 that I picked up a while back for like $30. The printer works great but it isn’t networked so every time something needs to be printed I have to tote the laptop into the room and hook it up via USB. Solution! An office was getting rid of a bunch of stuff recently and one of the things they got rid of was an HP JetDirect 300X j3263a. This device has a network port and a serial port that attaches to the printer.
Today I hooked up the JetDirect to my printer and the network. To get started I pushed the test button to get configuration info sheet printed. That much worked! I noticed that the device was already configured for a network so did some digging and found out I could factory reset the device.
Unplug the power from the JetDirect
Hold down the Test button while plugging power back in
Keep Holding the Test button for 30 seconds
Wait 10 seconds then unplug the power then plug back in (grabs an IP address from the network)
Wait 5 seconds after power on then press Test button (prints info sheet with IP address)
Ok so now I have a local IP address but for this to work properly I need to reserve the IP address issued in my router so that the JetDirect always has the same IP address.
Success! I setup a network printer pointed at the IP address allocated for the JetDirect. Windows discovered the LaserJet on the other end and installed with no issue. I could use it like this but I’d like to see what the new firmware would bring to the table.
Fail! I first tested to see if the JetDirect web interface was responding and it was but no options appeared. Turns out that this model uses Java and possibly some form of an ActiveX control. If this can’t be changed via a firmware update and is an issue there is always the Telnet interface on the JetDirect. Also features may not be enabled on the device.
Fail! I tried using the HP Web JetAdmin application but couldn’t get it to work. This maybe due to compatibility issues or because of the way I have my network setup.
Success! Next attempt TelNet. I used Putty as a client. Well there’s no login, no password, no username, nothing.
Usernames: root, admin, administrator, supervisor
Default telnet password: password
Below are some TelNet Commands to either enable or disable features. Disabled = 0 & Enabled = 1.
ipp-config: 0 (Enable/Disable Internet Printing)
ftp-config: 0 (Enable/Disable FTP)
ews-config: 0 (Enable/Disable Embedded Web Server)
Fail! Upgrading firmware via FTP. There’s supposed to be a folder called Download on the JetDirect via FTP but I don’t see one. Lets throw something at the wall and see if it sticks. I’ll just upload the firmware to the root directory…. and waiting. FTP errored out then telnet and web interfaced stopped responding correctly. Maybe it’s working? Everything I’ve read says that the JetDirect will automatically reboot….. Still waiting. Ok went to the printer and found that the printer was out of paper and that it had printed several messages/codes spit out blank pages leaving the printer empty. I put paper in and the JetDirect reset printing out the message below.
Fail! I attempted to the JetDirect update via TFTP with the commands below upon completion I got the message “Please wait, network upgrade will begin in a few seconds”. I used SolarWinds TFTP server on Windows 10. Nothing changes the version stays the same and the TFTP server log doesn’t show any activity from the JetDirect.
