Causes: 520 The main motor limit sensor does not go ON/OFF for more than 16 pulses while the main motor is operating, even after the elapse of 100 ms. 521 The position-A sensor does not go ON/OFF, between two detections of position-B, while the main motor is operating. 522 The position-B sensor does not go ON/OFF while the motor is operating, even when 3033 pulses are received at the Main FG. 523 Main-motor overload current 524 The clamp unit is not at the home position while the print drum is operating (Clamp sensor C: OFF, except during master disposal). 536 The drum failed to stop at position A. (over-run) 537 The drum failed to stop at position B. (over-run) 538 The print drum is not locked during operation. (Print-drum lock position sensor: OFF)
Remedy: Jam reset
Code: T02
Description: Elevator motor lock
Causes: 400 Both the upper and lower limit sensors were ON. 401 An overload current was detected in the elevator motor. 404 The lower-limit sensor does not go OFF within 2 s after the elevator motor operates in the raising direction from the lower-limit position. 405 The upper-limit sensor does not go ON within 12 s after the elevator motor operates in the raising direction. 406 The upper-limit sensor does not go OFF within 2 s after the elevator motor operates in the lower direction from the upper-limit position. 407 The lower-limit sensor does not go ON within 12 s after the elevator motor operates in the lowering direction. 408 The upper-limit sensor is OFF continuously for at least 2 s during operation of the elevator servo.
Remedy: Jam reset or switch on power again
Code: T03
Description: Clamp motor lock
Causes: 500 Clamp sensor C turns OFF following clamp unit initialization. 501 Clamp sensors A and B do not change within 800 ms when the clamp motor operates in reverse during clamp unit initialization (clamp sensor A starts at OFF). 502 Clamp sensors A and B do not change within 800 ms when the clamp motor operates in the forward direction during clamp unit initialization (clamp sensor A starts at ON). 503 Clamp sensor C does not go OFF within 800 ms when the clamp moves from the home position. 504 The clamp does not move from the home position to the open position within 800 ms during the operation of the clamp. 505 The clamp does not move from the open position to the position-A compensation position within 800 ms during the operation of the clamp. 506 The clamp does not move from the position-A compensation position to the clamp close position within 800 ms during the clamp operation. 507 The command does not coincide with the current position when clamp operation is started. 508 The command does not coincide with the stop position when clamp operation is stopped.
Remedy: Jam reset or switch on power again
Code: T04
Description: Overflow
Causes: 513 The overflow sensor was ON for a set number of times in succession during the 10- ms-interval overflow-sensor check.
Remedy: Jam reset or switch on power again
Code: T05
Description: Print-positioning pulse-motor lock
Causes: 603 The vertical-centering sensor does not switch OFF -> ON even when the vertical-positioning pulse motor is moved 12 mm in the ON direction. 604 The vertical-centering sensor does not switch ON -> OFF even when the vertical-positioning pulse motor is moved 12 mm in the OFF direction. 610 Timeout error during the vertical-print-position return operation 614 Vertical-print-position returning time out error 616 The one-step-positioning key was pressed with vertical-print-position information undefined.
Remedy: Jam reset or switch on power again
Code: T06
Description: Horizontal pulse-motor lock
Causes: 605 The horizontal-centering sensor does not switch OFF -> ON even when the horizontal pulse motor is moved 12 mm in the ON direction. 606 The horizontal-centering sensor does not switch ON -> OFF even when the horizontal pulse motor is moved 12 mm in the OFF direction. 611 Timeout error during horizontal-print-position return operation 615 Horizontal-print-position returning time out error 617 The one-step-positioning key was pressed with the horizontal-print-position information undefined.
