Solution: Replaced the main board on the Zebra 105SL, then performed a full cleaning and functional test to verify proper operation.

Problem: HP Color LaserJet MFP M680 would not print after a firmware update. Print jobs appeared in the log but never output; latency of up to 30 minutes was reported, or jobs disappeared entirely.

Solution: Technician reseated the formatter, measured ground voltage at the outlet at 0.7 V (elevated), and documented a complex mixed wired/wireless network topology as a likely latency contributor. Original firmware was unavailable via HP FTP; the next available version (Future Smart 3) was flashed successf
