Code: 2000
Description: main motor error
• The main motor ready signal (MOTRDYN) does not become ready (low level) a specified time after the main motor drive signal (MOTONN) is turned on. • The main motor ready signal (MOTRDYN) does not become ready (low level) a specified time after the main motor drive signal (MOTONN) is turned off.

Code: 2610
Description: paper feeder 1 feed motor error.
• When the paper feeder drive PWB of the optional paper feeder 1 drives the feed motor, no proper clock pulse is input from the feed motor clock sensor.

Code: 2620
Description: paper feeder 2 feed motor error
• When the paper feeder drive PWB of the optional paper feeder 2 drives the feed motor, no proper clock pulse is input from the feed motor clock sensor.

Code: 2630

Code: 4000
Description: polygon motor error
• The polygon motor ready signal (MOTRDYN) does not become ready (L level) within a specified time after the polygon motor drive signal (POLONN) is turned on (L level).

Code: 4200
Description: laser output error
• The pin photo signal (PDN) is not output within a specified time after the polygon motor ready signal (MOTRDYN) becomes ready (L level).

Code: 6000
Description: fixing heater lamp/fixing thermistor error
• The fixing thermistor disconnection detection circuit in the engine/high voltage PWB outputs the disconnection detection signal (THDEAD) to the CPU more than a specified time after power is turned on. • The fixing temperature does not rise at least 1 °C when the fixing heater lamp is continuously on for approximately 20 seconds during printer warm-up or in the standby mode. • The fixing temperature does not rise at least 1 °Cwhen the fixing heater lamp is continuously on for approximately 15 seconds during printing. • The fixing temperature does not lower when the fixing heater lamp is off for a specified time or more. * The fixing temperature is the average value calculated using the input voltage from the fixing thermistor detected several times in a specified time to avoid influence of noise and so on.

Code: 6020
Description: abnormally high fixing temperature error
• The fixing heater lamp runaway protection circuit in the engine/high voltage PWB outputs continuously the abnormally high temperature detection signal (HTEMPN) to the CPU for a longer time than specified.

Code: 6400
Description: fixing heater lamp control zero-cross signal detection error
• The zero-cross signal (ZCROSS) that is output from the power source PWB and input to the CPU on the engine/high voltage PWB is not input for a specified time.
