Manual PG adjustment function
This function allows the user to set the proper PG manually by setting the PG adjust lever
to one of the steps from -1 to 9. The selected step is converted into 4-bit data using
adjustment switches and the data is transferred to the controller circuit, where the PG is
determined based on the information.

Note)
1. PG width corresponds to the detected paper thickness.
2. Copy mode is used for paper with the thickness of 0.2 mm or more.
Automatic PG adjustment function
PG is automatically adjusted based on the paper thickness detected paper thickness
sensor which consists of the slit disc and the photo-electric transfer. Paper thickness is
detected in the following order:
1. PG home position is detected.
2. The gap between the platen surface and the printhead is measured by pressing
the printhead to the platen through the ribbon mask and ink ribbon.
3. The paper thickness is by pressing the printhead to the paper surface through the
ribbon mask and ink ribbon.
4. The printer sets the proper PG based on the measurement done in the step 2 and
3.
PG is determined for each paper loading action. When the CSF is used, this function is
activated when the printer is turned on. It is also performed when the paper quantity
sensor in the hopper is reset. However, no printing is performed during this operation.
