Selector 1: Handling paper at the occurrence of a paper feed timing error
When feeding paper to the print start position, the equipment might cause a feed timing error so
that the registration sensor goes ON signaling the presence of paper. This selector determines
whether the equipment will print on the current paper or eject the current paper without printing
and print on the next paper.
Selectors 3 and 4: Delay of FAX line disconnection when switching to the pseudo-ringing external
When the equipment 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 equipment 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.
