EPSON Stylus PHOTO 2100/2200 2.2.4.4 PG Detection (Release Lever) The following gives the relationships between the Release lever, PG sensor and Release sensor. Normal + ++ Release Release lever Revision B 2.2.4.5 PF Measurement Sequence ! The mechanical load in the paper loading path is measured at every power-on and I/C replacement/exchange sequence to perform control so that an adequate current value is set according to the mechanical load. ! When the mechanical load in the paper loading path reaches the specified value (B9 or BA address = 79), Fatal error is displayed. (When the cutter is not fitted) ! When the cutter is fitted, the mechanical load when the cutter is fitted is measured and reflected on the control since the mechanical load of the cutter must be taken into consideration to set the adequate current value. (If B9 + 6A address or BA+6B address= 79, Fatal error occurs.) PG sensor Release sensor Figure 2-12. Release Lever and PG Sensor Positions Table 2-13.
