Product specification and feature

2.2.5.3 Fusing

The temperature change of the heat roller’s surface is changed to the resistance value through the thermistor. The Heat Roller temperate (warmup) is measured by converting the resistance of the thermistor to a measurable DC voltage value. The AD converter changes it to a digital value so it knows when it has reach its proper fusing temperature. The AC power to the fuser lamp is controller by comparing the target temperature to the value from the thermistor. If the value from the thermistor is out of controlling range an error will occur and power disabled. The table below lists the types of Fuser Errors that can occur:

• Open Heat Error

During warmup, if the Fuser Unit does not reach its proper operating temperature within a predetermined time an “Open Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualified technician.

• Low Heat Error

After initial warmup had been achieved, if the Fuser Unit at any time does not reach its proper operating temperature within a predetermined time an “Low Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualified technician.

• Over Heat Error

If the Fuser Unit at any time exceeds the specified range [too hot] for proper operating temperature an “Over Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualified technician.

2.2.5.4 LSU

LSU receives the image data from PVC or HPVC and makes the latent image on OPC surface. It uses the single beam, LD.

The errors related to LSU are as follows:

By LReady : When the printing is started, the engine drives the polygon motor of LSU. After the specified time is elapsed, if the motor is not in a ready status, the engine detects the error that the polygon motor is not in a ready status. If this error happens, the engine stops all functions and keeps it at the error state. Also, the engine informs the error status of the main system and the error message is displayed at LCD window to inform the error status to the customer.

By Hsync : When the polygon motor is ready, the LSU sends out the signal called Hsync and it is used to synchronize with each image line. So, if the engine does not detect consecutively the signal for a fixed time, it defines the Hsync Error. If this error happens, the engine stops all functions and keeps it at the error state. Also, the engine informs the error status of the main system and then the error message is displayed at LCD window to inform the error status to the customer.

LSU Error Recovery: If the LReady or Hsync error occurs the paper is exited with no image on it. The engine mode is changed to recovery mode and the engine informs the main system of the engine mode. And the engine checks the LSU error. If the error doesn’t happen, the printing job will be proceeding.
