Remedy When A Paper Out, Double Feed Or Paper Jam Error Occurs - Epson Stylus Color C70 Service Manual

EPSON Stylus COLOR C70/C80
3.1.4.1 Remedy when a paper out, double feed or paper jam error
occurs
This section provides check points and corresponding actions which are necessary
when the Paper Out Error problem has occurred because of either of the following
reasons:
Paper is set in the ASF hopper but not fed.
Paper is fed but not detected by the printer.
Indicates the checks and remedies to be carried out if the paper feeds normally and the
printer can recognize this, but the paper jams during printing or when it is being
ejected.
The reason why possible causes of paper out and double feed errors are listed together
is because double feeding during duplex printing can cause problems with page
numbering and render the whole printing job useless, so that if it is judged that the
paper is longer than the normal length, the current page is fully ejected, and then a
paper out error is indicated straight away to prompt the customer to reset the paper.
Furthermore, it is also assumed that such double-feed errors will result in the paper
running out before the last page or the last few pages are printed, and so double feed
and paper out errors are handled in the same way. This is considered to be a refinement
of conventional paper jam detection.
Be sure to follow the steps in the order described in the tables.
NOTE: If the finding for the question is Yes, take the action described in the right
column. If "No", proceed to the next step.
