0001 An open circuit has been detected for thecount pulse signal.Turn off the main power, and check for anopen circuit in the cable; then, turn themain power back on.E061 There is a potential control error/there is an APC error.0001 As a result of potential control, the drumsurface potential (VL2) of the backgroundis 200 V or higher (i.e., causing a solidblack image).- Replace the potential sensor unit.- Replace the laser scanner unit.- Replace the DC controller PCB.0002 The primary charging output used at timeof printer output and the drum surfacepotential after laser output is identified asbeing 200 V or more (i.e., causing a solidblack image).E100 There is a BD error.0001 A check is made of VLOCK at intervals of100 msec while the laser is on. An errorwill be identified if it is not detected 10times in sequence.- Replace the laser scanner unit.- Replace the DC controller PCB.E110 There is a polygon motor error.0001 - Although the polygon motor has beenturned on, VLOCK is not detected at allwithin 76.5 sec.- At time of a shift from full-speed to half-speed control, VLOCK is not detected atall for 7.5 sec.- At time of half-speed control, a check ismade of VLOCK at intervals of 100 msec.An error will be identified if it is notdetected 10 times continuously.- Replace the laser scanner unit.- Replace the DC controller PCB.E121 There is a controller cooling fan error.0001 Even though the controller cooling fan hasbeen turned on, the controller cooling fanstop signal has been detected for 5 sec ormore.- Check the connector for any fault inconnection.- Replace the fan.E196 The EEPROM is faulty.Code Description Remedy
