Clearing the status counter After completing the repair of what caused the error, proceed to do the following: (1) While pressing [0] and [8] simultaneously, turn ON the power. (2) Enter [700] with digital keys, then press the [START] key. (3) Rewrite the status counter to "0", then press the [SET] or [INTERRUPT] key. The status counter is dispalyed as follows: [C41]: "1" or "2" [C42]: "6" [C43]: "4" [C44]: "5" [C46]: "7" [C47]: "8" [C48]: "9" (4) Turn OFF the power and then back it ON again, and make sure that the copier gets ready normally.

Error code:	C48
Description:	Heater abnormal (high temperature)
Remedy:	1. Checking the thermistors (1) Is any thermistor connector disconnected? (2) Are the thermistors (upper/lower, center/rear) in proper contact with the upper and lower heat rollers? (3) Are the harnesses for the thermistors (upper/lower, center/rear) open-circuited? 2. Checking the heater lamps and SSRs (1) Check if the upper or lower heater lamp is open-circuited. (2) Check if the upper or lower heater lamp connector is disconnected. (3) Check if the thermostat is blown out. (4) Check if the upper heat roller or lower heat roller SSR connector is disconnected. (5) Check if the AC harness is open-circuited. (6) Check if SSR or the switching power supply is broken. 3. Checking the LGC board (1) Check the LGC board if the connector J123 is disconnected. (2) Check if the conductor pattern on the LGC board is open- or short-circuited. (3) Replace the LGC board. 4.
