Bit 2: Forwarding
Bit 3: Authorized reception
Bit 4: Connection to answering machine
Bit 5: Remote control features
Bit 6: Continuous polling
4045
Bit 0: Display of both RTI and CSI on the LCD
Bit 2: Printout of forwarded messages
4047: Number of page retransmission attempts (Hex code)
4048
Bit 5: Stop key during memory transmission
Bit 6: First page to be retransmitted (memory tx)
4049
Bit 0: Keystroke Program execution method
0: Press the programmed Quick Dial Key
1: Press the programmed Quick Dial Key then the Start key
Bit 2: RDS
Bit 3: On-hook dial
Bit 4: Hold
404B: Contrast threshold - Lighten (Hex code, from 00 to 1F)
404C: Contrast threshold - Normal (Hex code, from 00 to 1F)
404D: Contrast threshold - Darken (Hex code, from 00 to 1F)
4053 Bit 0: Default resolution used for copy mode
4054 Bit 0: Reduction during printing
4055
The amount of remaining memory below which ringing detection (and therefore substitute re-
ception) is disabled if the printer is out of action (hex code, from 00 to FF, unit = kbytes)
• One page is about 24 kbytes
• If this is kept at 0, the machine will detect ringing signals and go into receive mode even if
there is no memory space left. This will result in communication failure.
4057
Image/Text detection threshold in halftone mode (Hex: 00 - 1F)
• 01: Almost all the data will be processed without halftone, even if the fax message contains
photographs.
• The threshold increases with increments in the setting from 01 to 1F.
• 00, 1F: Almost all the data will be halftone processed, even if the fax message contains
only text.
4058: Number of redialing attempts, including the first dialing attempt (memory tx)
4059: Redialing interval (memory tx)
405D: Time for which RDS is enabled after the user has switched it on
