The following gives the relationships between the Release lever, PG sensor and
Release sensor.
Figure 2-12. Release Lever and PG Sensor Positions
Note: When the PG position is the + position (PG sensor: OFF, Release sensor: OFF, Setting
mode: Board paper, Thick paper), the printing method is forcibly changed to Uni-D.
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<H> or BA<H> address = 79<H>), 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<H> + 6A<H> address or BA<H>+6B<H> address= 79<H>, Fatal error
occurs.)
