[QUOTE="firefighter4443, post: 195534, member: 1494"] I got this from a Google Search, second resuld: "[PDF] Page 1 - () page1 HP LaserJet - COMMON ERROR CODES". 50 FUSER ERROR ALL • Temporary error code, turn printer off then wait 20 or 30 minutes the turn back on • Low or unstable power - check the wall voltage, if on a surge protector, plug straight in two the wall • Bad fuser assembly • Bad low voltage power supply • Bad DC controller HP 9000 ERROR 50.X • Improperly seated fuser • Replace the fuser assembly • Replace the upper cable guide assembly • Replace the low voltage power supply • Replace the DC controller Also, here's the power requirements for the HP 9000 series printer: power requirements — Source:100 to 127 volts (±10%) Frequency:50 to 60 Hz (±2 Hz) power consumption — Printing:1040 watts maximum Standby (ready state):90 to 100 watts Powersave mode:35 to 45 watts (ENERGY STAR® compliant) Using this equation: To convert Watts to AMPS when volts are known: AMPS = Watts / Voltage I = P / E You need a dedicated 8.6 AMP circut, so say 10 AMP. So a simple solution might be to look at where the pinter is plugged into. Is it into a power strip or the wall? If its in a power strip, pull it out and plug directly into the wall. More complicated, if you've got the time and expertise needed, find out how many amps that wall circut can handle, and how many things are plugged into it. After that, you might need to get an HP certified technician to look into the printer. Hope you solve your problem. [/QUOTE]
