Loading Film and Paper
Introduction
Loading film onto reels or prints into drums needs to be accomplished before the processing is
begun. The pages linked below are detailed instructions on how to load your film or prints. Also
included are pages on tank and drum care and identification of their components.
Common Procedures
If you are new to film loading, practice in the light with scrap film.
After you become comfortable with the procedure, practice in the
dark. With reel loading, you may need to practice before
becoming proficient. It should not take long to become
comfortable with the loading procedures.
All the steps for loading of film are done in total darkness. Do not
use any safelight. Be sure that there is no light source, however
small, in your loading area. To check the light-tightness of an
area, turn off the lights and wait for at least one minute. Look
around after your eyes have become accustomed to the dark.
Be certain that there is no device that may light only
occasionally, such as line lights on phones or space heaters. If
your processor is in the same room as your film loading, cover
the heating indicator. Turn off, (or cover) analyzers and
enlargers, or any device with a display or lights. If there is no
light-tight room available, use a changing bag, box or tent (such
as JOBO's #6775).
You will need a pair of scissors (safety tipped) for 35 mm film or roll film, and a bottle opener (or
film can opener) for 35 mm film. Have all tools, reels, tank body, center core, loader (if used) and
lid located conveniently in front of you. A waste receptacle at arm's length would be convenient.
Check for proper assembly of tank lids (funnel in place), tank - module assembly and center core
assembly (if using a module). Note their locations before turning off the lights.
You may mix reels loaded with 35 mm 120 roll film, 220 roll film and sheet film (on reels) in the
same tank with these precautions. Never use 1501 reels in a 2500 series tank. Never mix stainless
steel and plastic reels. Note the tank's required volume of chemicals for each type of reel you are
using. Whatever the highest volume of chemicals listed will become your minimum amount of
chemicals for the tank as it is loaded.
