This chapter describes how to insert IX240 film for scanning and
how to remove film from the adapter.
4.1 Inserting film
IX240 film must be developed before it can be scanned. To deter-
mine whether a roll of IX240 film has been developed, examine the
end of the film cartridge where its current status is marked. If there
is a white square showing in the fourth box, the film has been
developed and can be scanned.
To scan IX240 film, press the latch button to open the adapter
cover.
