Explanation
This error is the most common type of paper jam. Possible
causes are (x1=media size):
*Multi sheet feeding.
*A tray size sensing problem.
*The media feeding from the paper source is slipping or
media is slipping in input to the printer.
The input sensor was covered during POST by a piece of
media still in the machine when it was turned on.
*Clear the media from the printer.
*Run the base sensor test (input sensor) from the diagnostic
tests menu to test the input sensor and flag for correct
operation.
There was a media at the input sensor too early. There was
not enough time between printhead start and the printhead
mirror motor to lock. Possible causes for this error are:
*Paper might be pre-staged in the paper source tray.
*Paper is picking too fast.
*A defective input sensor.
A paper jam has been declared by a smart device. Immediate
stop homing not allowed.
A paper jam has been declared by a smart device. Homing
was allowed before the stop.
The option tray pass thru sensor was never actuated by a
piece of media. (x-1=media size) (x-2=media source) (x-
3=paper source where paper jam was detected)
*Run the sensor test for the option tray that is displaying the
error code and check the pass thru sensor for that tray for
correct operation.
*Check for paper picking from the selected paper input
source.
*If the error is being detected from a lower paper source, see
if paper is feeding correctly from a paper source above the
detected source.
