Note:
- Selector 1 is applicable only to models equipped with flat-bed scanners.
- Selectors 3 and 4 are applicable only to models supporting pseudo-ringing of a connected
external telephone.
- Selector 1: Handling paper at the occurrence of a paper feed timing error (Not used.)
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.
