Chapter 2 Operation
2.8 Form Jam Detection
OKIPAGE 8c checks for a paper jam when the page printer is powered on, and during printing. When a
paper jam is found, the OKIPAGE 8c immediately stops the printing process. To recover the printer,
open the cover, find and remove the jammed paper, then close the cover.
Error Conditions
Form feed jam Three hopping operations are made, but the Form Feed sensor
(Entrance) does not turn on within a preset time after the Form Feed
sensor 1 turns on.
Convey jam The ejection sensor does not turn on within a preset time period after
the Write sensor detects the front end of paper.
Ejection jam
The eject sensor detected the front edge of the paper, but does not
detect the rear edge of the paper within a preset time period.
Form size error
The form size (obtained by measuring the time period between the rear
edge of the paper passes by the Form Feed sensor 2 after the front
edge of the paper passed the Write sensor) is longer by 45mm than the
specified form length.
* To obtain the form size, measure the time interval from when the front edge of the paper passes the
Write Sensor until the rear edge of the paper passes the Form Feed Sensor 2. A Form Size Error occurs
when the specified length is exceeded by 45 mm.
