Detailed Description of the Controls

Numbers in brackets refer to the picture on page 6
Audio On/Align switch (1) and Align light (2)
When this switch is placed in the up position then audio from the receiver can be heard. This
can be used to listen to the quality of the radio reception on any of the channels. Placing the
switch back in the center position turns off the sound.
If a map printout is started manually or if the synchronising signal at the beginning of a
transmission is missed the picture may be out of alignment. This shows up as a picture
starting part way along the paper instead of at the left side.
To manually align a picture:
Look at the picture being printed
Find the normal left hand edge of the picture
Note where this is on the 0-7 scale on the front panel
Hold down the align switch (3)
Count the number of flashes of the align light (4)
When this is equal to the number on the scale release the align switch promptly
The rest of the picture should be correctly aligned
In the sample map below you would need to hold the align switch for 4 flashes of the align
light to realign the left edge.
Fast Paper Feed switch (3)
This switch is used to feed the paper out at a faster than normal rate. This allows a
completed map to be cleared from the C-Fax printer before tearing it off.
It is also useful for the manual align procedure described above, by feeding out some of the
picture so it is possible to check the alignment sooner.
Paper Out indicator light (4)
When the end of the paper roll is reached this red light will flash to indicate the C-Fax is out
of paper, and the C-Fax will stop printing. There is normally a warning stripe printed on
most types of paper near the end which shows during the last metre or two to warn that the
paper is running out.
