Potential Control Chapter 7 7. Laser light Basics Sequence Of Operations Chapter 7 7. Performs a series of charging operations to stabilize the drum potential. Uses the potential control mechanism that is used when the main power switch is turned on. The primary charging bias is set to a fixed value. Measurements are taken multiple times to determine the relationship between the drum surface potential VD and the grid bias.

The machine takes measurements multiple times to determine the relationship between the drum surface potential VL and the laser output. To that end, the machine executes potential control for transparency mode, thus determining the target value for transparency mode. Page Chapter 7 2. Charging Mechanism Chapter 7 7.

However, there is no way of returning the history to the HDD. Use one of the 2 slots. There is no optional memory for expansion.

If there is a backup of the SRAM data i. Points to Note When Fitting the Security Expansion Board Whenever possible, do not replace the main controller PCB as part of the troubleshooting work conducted in relation to the installation of the security expansion board option. The machine checks the compatibility between the HDD and the main controller PCB when a security expansion board is installed. Replacement with a new board will cause the formatting of the HDD to start automatically, thus deleting all user data.

Before Starting the Work backing up the data If possible, perform the following: As such, if you have initialized the RAM on the reader controller PCB or replaced the PCB, it is important that you newly enter service mode settings and execute appropriate adjustment items. The machine remains powered after the main power switch is turned off as long as the power plug is connected to the power outlet. Be sure to disconnect the power plug from the power outlet.

You can check the surface potential in service mode. Disabling the Auto Control Mechanisms As a way of checking the mechanisms used for corona current control, lamp intensity control, or developing bias control, you may disable the auto control mechanisms hereafter, non-auto control mode. As a first-aid measure when a fault exists in the auto control mechanism, you may use non-auto control mode; keep in mind that all outputs in non-auto control mode are fixed to standard values.

Procedure 1 Make the following selections in service mode, and enter '0': In non-auto control mode, all settings used for coronal current control, intensity control, developing bias control will be set to standard settings stored in ROM. In non-auto control mode, if the fault is corrected somewhat, you may suspect the potential measurement unit or the DC controller PCB.

Zero-Level Check One way of finding out if the surface potential control circuit is good or not is to use a zero-level check. A zero-level check is made to see if the microprocessor registers 0 V when the surface potential of the drum is 0 V. Using the result of the check, you can find out if the microprocessor on the DC controller PCB or the measurement unit is good or not; a zero-level check may take either of the following two methods: Method 1 1 Turn off the power switch.

When fitting the checker electrode to the potential sensor, make sure that the magnet of the checker electrode will not come into contact with the potential sensor cover. Never bring the clip into contact with the sensor cover. Be sure to fit it fully away from the sensor window. When fitting the checker electrode to the potential sensor, be sure that the magnet of the checker electrode will not come into contact with the potential sensor cover.

Method 2 1 Turn off the power switch. Be sure to keep it fully away from the sensor window. Once you have turned on the power switch, do not touch the potential sensor assembly.

If the reading is as indicated in Method 1 but is not in Method 2, suspect dirt on the sensor or a fault in the potential measurement unit.

If the reading is as indicated in both Method 1 and Method 2, assume that the signal path and the operation from the potential sensor unit to the microprocessor on the DC controller PCB are normal. Chapter 2 3 Remove the environment sensor, and fit the environment sensor jig FY in its place. The environment sensor jig FY is precisely adjusted at the factory. Be sure to keep it in an air-tight case with a drying agent.
