Turn the KNOB (Fig. 5-6, Item 2) clockwise and hold so that print head barely touches the platen roller.
There should be no pressure exerted on the roller; there should be no spring plate deflection.
While holding the PRINT HEAD down with the KNOB, lower the rear upper NIP ROLLER assembly
(Fig. 5-6, Item 12) so that it contact the DRIVE ROLLER (Fig. 5-6, Item 11). Retighten the set screw.
5.9 Head Down Sensor Adjustment
Head down sensor assembly (Fig. 5-5, Items 3-4) may require adjustment when cylinders, platen roller,
rear nip roller or linkage is replaced.
Note: Head down sensor should not require adjustment when print head is replaced.
Disconnect air, turn the power OFF and remove the side panel cover. After the panel has been removed,
turn the power ON.
!
Caution
: While power is ON and panel is removed, do not contact wires, PC boards, connectors or
any other component inside panel with hands or other objects. Electrical shock or component damage
may occur.
While observing the HEAD DOWN LED on the Interface PC Board (Fig. 5-8, Item 1) perform the
following steps:
Turn KNOB (Fig. 5-6, Item 2) clockwise until PRINT HEAD (Fig. 5-6, Item 4) contacts print head.
If the head down LED turns ON at the instant that the print head touches the platen roller, the HEAD
DOWN SENSOR FLAG collar (Fig. 5-5, Item 4) is set properly.
Test again and ensure that the LED turns on at the instant that the print head contacts the platen roller.
If the LED lights PRIOR TO or AFTER the print head contacts the platen roller, loosen the HEAD
DOWN SENSOR FLAG COLLAR set screw (Fig. 5-5, Item 4) so that the flag turns on the shaft but
does not swing free.
If the LED lights PRIOR TO the print head contacting the platen roller, rotate the collar CLOCKWISE
in small increments so that when the print head contacts the platen roller, the print head down LED
lights.
If the LED lights AFTER the print head contacting the platen roller, rotate the collar COUNTER
CLOCKWISE in small increments so that when the print head contacts the platen roller, the print head
down LED lights. Once properly adjusted, retighten the set screw.
