<P> The next module is the left feed module . This section of the machine is where cheques are pulled into the transport path . The MICR line is magnetized and read in this part of the machine . The MICR information is passed to the control unit for additional processing . This module also has the ability to insert tracking documents into the stream of cheques in the transport . On Models A-F, the item numbering feature or INF was also found in the left feed module . The INF could print a unique 8 digit number on the back of each check . </P> <P> The right feed module performs two functions . One is the input area, where up to 4800 cheques can be placed to be fed into the left module . Before this happens, all documents are "jogged" before they are moved into the transport . This process causes the cheques to be lined up better for feeding into the left feed module; institutions use an external jogger as well . The second function is the Programmable Item Number Endorse system or PINE, which appeared with the model XP1 . It is a high speed ink jet printer used to print document tracking number on each cheque which goes through the machine . At the same time an "endorsement" stamp is sprayed on to show which institution has handled the cheque . On Models A-F, an "endorsement" stamp is used to show what institution has handled the cheque . </P> <P> After this, the document passes through two optional modules . To meet the requirements of the American Banking Association, one of the two must be used . Until October 2003, the only legal way to provide long term archiving of cheques was microfilm . This is one of the optional modules . High speed strobe lights illuminate the cheques and mirrors direct the lit image through a camera onto film . The front and back of the cheque, plus the item number are transferred to the film . </P> <P> The other optional module is the Image Capture Processor (ICP). High speed digital scanners generate pictures of the front and back of the check . To keep up with the speed that documents move by the scanners, four PC's are used--one cheque directed to one PC, the next to the second and so forth . These images are consolidated to a fifth PC which sends the images to a host computer system, where the digital images can be stored on hard disks . After this they can be backed up using magnetic tapes for long term archiving . As of October, 2003, these images, rather than the physical cheques, can be used when institutions needs to exchange cheque information . </P>
