CP80 and CP80 Plus Service Manual
The leading edge of the card is registered by the magnetic stripe sensor.
The optical encoder measures the distance the card travels during the
encoding process.
All tracks of the card are written simultaneously.
On the return pass, the card data is verified.
When the leading edge of the card reaches the platen roller, the printhead
cam engages and lowers the head onto the card.
The ribbon motor is engaged. The motor is over-driven, and the spindle
clutch slips as needed to match the speed of the card.
After a panel is printed, the printhead is raised and the card is returned to
the input sensor.
The ribbon motor advances to the next panel by examining the ribbon
encoder.
The process is repeated for the remaining panels.
The duplex entry sensor detects the card and determines the position
within the flipper.
With the magnetic clutch relaxed, the drive rollers pull the card into the
module.
The clutch is engaged and the motor rotates the flipper to the return
position.
The clutch is released, and the motor drives the rollers to move the card
back into the printer. (The rollers always move in the forward direction,
but since the flipper assembly is inverted, the card is moved back into the
printer.)
The duplex entry sensor detects the card and determines the position
within the flipper.
With the magnetic clutch relaxed, the drive rollers pull the card into the
module.
The clutch is engaged and the motor rotates the flipper to the vertical
position.
