58Advanced Operations and SetupsEClerk interrupt functionThere are two types of clerk interrupt function, illustrated by PROCEDURE 1 and PROCEDURE 2 below.• In PROCEDURE 1, each clerk possesses a unique clerk interrupt buffer, and so the clerk interrupt functiongives each individual clerk the ability to perform an independent registration operation. In this case, each clerkis individually linked to a unique clerk interrupt buffer.• In PROCEDURE 2, multiple clerks use the same clerk interrupt buffer, and so a single clerk interruptoperation (clerk change during registration) can be performed any registration is in progress. In this case,multiple clerks are linked to a single clerk interrupt buffer.Note the following important points concerning the clerk interrupt function.• The register must be programmed to allow use of the clerk interrupt function.• You cannot use the clerk interrupt function on a register set up to function as part of a check tracking system.In the REG and RF modes, clerks can be change while a transaction is in progress, making it possible formultiple clerks to simultaneously perform registrations using a single register.For example, if clerk 1 is interrupted while registering a transaction, clerk 2 can use the same machine toregister a different transaction. Then clerk 1 can continue the original registration from the point where it wasinterrupted.PROCEDURE 1Clerk 1Clerk 2Sign onSign onSign onSign onSign onRegistration A Post receipt AFinalization AFinalization BRegistration BPROCEDURE 2NOTES• A guest receipt can be issued following clerk change, and receipts can be issued separately for each clerk.Clerk 1Clerk 2Sign onSign onSign onRegistration A Finalization A + BRegistration B
