| Remedy: | Error clearance 1 Have you cleared the fuser error in the Error Clear Mode? Yes Wait until the Fuser Unit is enough cooled down. Then select the Error Clear Mode and clear the concerning error. Wires 2 Are wires among Lamp (H1), Solid State Relay (SSR1) and Thermistors (TH1 & TH2) connected properly? No Connect them properly. Lamp (H1) 3 Unplug the machine, and then check the resistance of Lamp (H1) with the multimeter. Is it 15 ohm or lower? No Replace the Lamp. Thermistors (TH1 & TH2) 4 Select the Information Mode, and then check the temperature of fuser detected by Thermistors (TH1 & TH2). Item No. : 00 (Fuser temperature 1) 01 (Fuser temperature 2) Is each temperature normal? No Replace the concerning Thermistor. Confirm that the machine is turned on, and then check the voltage of the orange line (J220-4). Is it 24V? No Replace the DC Power Supply if there is no problem with the wires. DC Power Supply (DCP1) or Fuse 5 Confirm that the machine is turned off, and then check whether or not each Fuse is broken. Is any Fuse broken? Yes Replace the Fuse. Relay (RY1) 6 Select the Device Operation Mode, and then change the signal of the following signal to “H”. Signal Code : 22 (Fuser Relay) And check the resistance between the following points. Between RY1-2 and RY1-4 Between RY1-6 and RY1-8 Is the each resistance almost 0 ohm? No Replace the Relay. Solid State Relay (SSR1) 7 Select the Device Operation Mode, and then change the signal of the following signals to “H”. Signal Code : 22 (Fuser Relay) 21 (Fuser Lamp 1) Then check the voltage between J105-1 and J105-2. Is it 0V? Refer to the page 8-16 as for the Device Operation Mode.) CAUTION Change the signal of “21” (Fuser Lamp 1) to “L” after checking! No Replace the PW10520 PWB. Yes Replace the Solid State Relay |
