While scanning large projects (such as the Palma project) there are many complications to consider, thus requiring an approach and process to the project with the following guidelines that will help clear away or prepare for project anomalies that may occur.

assess the project and potential complexities involving any duplicates or multiples of slides, photos, prints, negs, positives, or whatever the media needed to be scanned
note and remember the defaults that are reverted to when powering on the Epson Scan program, ie. the "checking" of the "digital ice" option when needed
when powering up the scanner on a new day of work or after a re-boot RE-CHECK that "digital ice" is CHECKED!
normally there will be a prefix and number applied to the file name; duplicates or multiples will be appended with "b", "c", etc.
negatives and positives will be placed in the slide holders with the emulsion side up
folders will be created associated to binders, envelopes, boxes that have been itemized by the client
the Epson scanner will take the first drawn marque as the first scan to be done; so while this marque can be duplicated, give note to where the duplicated marque is positioned (ie. the neg to be scanned next should be the next logical scan that will be placed in order when re-sleeving the neg to go back into the binder)
with large scanning projects the 2 scanners can used in tandem
when using 2 scanners at once - the project should be split up evenly within the current page, set, or group of items to be scanned to keep on top of the correct numbering. This is so that should a numbering error or otherwise be made a correction can be made as soon as possible
a sheet can be used with 2 columns dividing the page for Epson A, and Epson B - or Epson 1 and Epson 2 to keep a running tally of the scans that are completed, this sheet can easily be transported between both scanner locations to verify numbering
a sheet of paper can also be used for each scanner can be used to place the negative/positive sleeves in the same position to "mark" the position of the top/bottom of the page that those sleeves came from (for example if they came from a sleeve page from a binder brought in by the client. This process helps to return the slides/negs to the same position as they were in when received from the client
the obverse side of prints will be scanned then of those that do not have any identifiable notation will be deleted later
