Selector 1: Handling paper at the occurrence of a paper feed timing error
When feeding paper to the print start position, the machine might cause a feed timing error so that
the registration sensor goes ON signaling the presence of paper. This selector determines whether the
machine prints on the current paper or ejects the current paper without printing and prints on the
next paper.
Selectors 3 and 4: Delay of FAX line disconnection when switching to the pseudo-ringing external
telephone
When the machine receives a phone call, it can make the connected external telephone ring (so called
pseudo-ringing). During pseudo-ringing, if you pick up the handset of the external telephone, the line
might be disconnected due to cut-off of the line current.
To hold the line, the machine may supply line current by making use of the pulse generator circuit
that forms a parallel loop. This way the FAX line disconnection may be delayed. These selectors
determine the delay period.
