Chapter 5 Adjustments
5.1 Setting of LED Print Head Drive Time
Adjustment point: Technical Functions No. 28 through 31.
* To access the Technical Function mode, press
SELECT FUNCTION key once, COPY key twice and "2"
key (When no messages are in memory).
Adjustment:
1) Turn AC power ON.
2) Set the LED print head to the appropriate ranking by following Table 5.1.1 below.
3) Intensity ranking is determined by the first, second and third digits from the right in the LED print head
serial number (i.e. in S/N ---XX056, 056 is the intensity ranking.) In each row there is a rank marking range
(left most column). The ranking printed on the LED head should fall within one of these ranges. After
locating the appropriate range, follow the row right to the asterisk column. Follow the asterisk column
vertically to see the appropriate technical function settings.
4) Set technical functions 28 through 31 according to the recommended values.
Table 5.1.1 Setting of Technical Function No. 28 to 31
Note: When the rank marking of the replaced LED print head (new part) is the same as that of the
used LED print head (old part), you do not always have to set the LED print head drive time.
