CST-VLM4 Adj Cassette 4 level detect threshold VL
Lv.2 Details To adjust the timing to switch the scale indicating paper level in the
Cassette 4 from “3” to “2”.
As the value is larger, switching of the level display becomes earlier.
For example, if you prefer to switch the scale when paper level
reaches 25 mm instead of 15 mm, place a stack of papers which
height is approx. 25 mm in the cassette and then increase the setting
value by 1 at a time until the scale becomes “2”.
If the scale is switched although paper level is 40 mm, place a stack
of papers which height is approx. 35 mm in the cassette and then
decrease the setting value by 1 at a time until the scale becomes “3”.
If the value that satisfy both of the above conditions is set, the scale
is switched when paper level is in the range of 25 to 35 mm.
Use case Upon user’s request (to individually adjust the timing to switch the
paper level display)
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
2) Pull out and then insert the cassette.
Caution - The setting is reflected after removing and then installing the
cassette.
- When the value is increased/decreased greatly, the actual timing
may be deviated from the target. Therefore, change the value by 1 at
a time while checking the scale.
Display/adj/set range -4 to 4
Appropriate target value 0
Default value
0
Supplement/memo The timing to switch the scale of paper level from “3” to “2” varies (9
to 40 mm) due to individual difference of the motor. With this item,
the variation is corrected.
Since paper levels corresponding to the other scales can be detected
almost correctly, there is no need to adjust the timing of switching.
