13.5 Memory/Storage Status
• To display the condition and amount of the memory and MFP storage.
13.6 Color Regist
• To check when there is a color shift.
• For each of C, M, and Y, the color shift amount (in X and Y directions) at two locations (one at the front and the other in the rear) is
displayed.
• Individual color shifts of C, M, and Y are based on K and their amounts are displayed. (Display unit: dots)
• The data is updated after a color shift correction has been made or color shift adjustment has been completed.
13.7 Load Check
• To check each device (electric component) for proper condition by individually activating the load associated with the device.
• To identify faults at the time of troubleshooting.
NOTE
Take note of the following during the load check mode.
• No malfunction is detected and no count is taken of consumables life and related items.
• Two or more devices (motors, clutches, solenoids, and fans) cannot be checked simultaneously.
• Detection of proper installation of various types of units and waste toner box does not function. During the check procedure,
therefore, make sure that the unit in question is installed correctly or yet to be installed.
<Procedure>
1. Open the front door, lower front door or the right door.
2. Touch [Start Load Check].
3. Close the door opened on step 1.
4. Referring to the load check list, enter a check code.
5. Referring to the load check list, enter a multi code.
6. Press the Start key.
• When pressing the Start key, the specified load is activated. The Start key blinks in orange.
7. Check the load operation and output of signals.
8. Press the Stop key to stop the check operation and check the result.
NOTE
▪ Depending on the type of load being activated, after the lapse of the specified time or after the transition to the specified
state, the corresponding device automatically stops working.
▪ When 'NG' is displayed, check the wiring and connectors.
9. To check another load or signal output, repeat steps 4 to 8.
10. Turn OFF the main power switch and turn it ON again more than 10 seconds after.
