These are the steps for AutoLoad with TOF:
1. With the head mechanism latched in its normal print position, the operator
inserts new media until it stops at the drive roller.
2. The printer waits a programmable amount of time as set by the ^D120
command (default is 1.5 seconds) after it senses the new media to make it
easier for the operator to align the paper.
3. After the time delay, the printer feeds the paper forward until the leading
edge of the media is seen by the TOF sensor.
4. The feed forward stops and then the printer retracts the media a
programmable distance as set by the ^D123 command and stops.
Set ^D25, bits 6 and 7 to enable the AutoLoad+TOF feature.
Note: TOF Error—When the printer cannot complete a TOF, it will stop, the LED will turn
“RED,” and if the queried, the printer will report a “>TOF ERROR< or 0x1F depending on
the response mode of the printer. To clear the error, press the print button. Another TOF
may then be attempted.
^A ^D COMMAND
XX 120 AutoLoad Delay Selection.
AutoLoad Delay = xx milliseconds (up to a maximum of 5000 milliseconds or 5
seconds.
The AutoLoad Delay is the amount of time that the printer waits after detecting
that media has been put into the printer before it starts feeding it in. A small
amount of delay makes it easier for the operator to get the paper fully inserted
into the printer and properly oriented before paper motion begins.
The default value for AutoLoad delay is 1500 milliseconds (1.5 seconds). The
operator may use this command to adjust the delay to suit individual
preferences. ^A0 turns the delay OFF so that the driver roller is activated as
soon as media is detected. Since this is a volatile command the default
setting will be restored every time the printer’s power is cycled “OFF” and
“ON.”
Example: Have the printer wait 1.25 seconds before feeding paper on AutoLoad.
^A1250^D120
121 Top of Form Command.
This command initiates a TOF operation:
a) Media is advanced until the leading edge is detected by the “Top Of
Form” sensor,
b) Media is then retracted to position the leading edge of stock to the
correct starting location.
This command is useful when using the AutoLoad + Top of Form command.
