ADJUSTMENT

Set the Tester to the resistance value measurement mode, and insert the Alligator

clip cables into both terminals of the Tester. Connect the lead wire of the Gauge

and the Grounding plate on the Carriage side or the Top frame with the Alligator

terminals of the Tester.

Figure 5-12.

Connection of Lead Wire

Return the Release lever to the front position to minimize the PG.

10.

Move the Adjust parallelism bush (right) until continuity is confirmed. Raise the

Adjust parallelism bush (right) one step up from the position where continuity was

confirmed. At this time, move the Adjust parallelism bush (right) to make sure that

the position where continuity is confirmed is the same as the position where

continuity is lost.

11.

After adjustment is over, place the Release lever in the envelop mark position

again to increase the PG.

12.

Repeat Steps 6 to 10 for PG main shaft left adjustment, PG sub shaft right

adjustment, and PG sub shaft left adjustment in this order. At this time, press the

carriage unit movement button in the adjustment program to move the Carriage

unit.

If the rigidity of the Alligator terminal cables of the Tester is high,

the Gauge adjustment plate will move. Therefore, it is

recommended to use the cables whose rigidity is as low as

possible.

The following figure shows the states of the Adjust parallelism

bush (right) and PG.

Figure 5-13.

Parallelism Adjustment Lever Operating Method

As in Figure 5-13, moving the Adjust parallelism bush (left) or Sub

adjust parallelism bush (right/left) to the printer front side increases

the PG, and moving it to the printer rear side decreases the PG.

If the continuity state of the Tester is instable, there is a strong

likelihood that the drops of ink or Shipping Liquid have stuck to

the Head surface. Therefore, remove and wipe the Head.

By moving the Main Parallelism Adjustment lever with one

notch, the CR unit moves 0.05mm upward or downward.

By moving the Sub Parallelism Adjustment lever with one notch,

the CR unit moves 0.08mm upward or downward.
