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.
