SATO CL608 & CL612 SERVICE MANUAL
SECTION 5 – Mechanical Adjustments
5-4 Print Head Balance Adjustment
Required Equipment: #2 Pozidrv Screwdriver
10mm wrench
STEP PROCEDURE
1. Connect the power cable to the printer and AC outlet. Turn the printer
ON.
2. Raise the main cover and load the ribbon and label stock. Fig. 5-1
NOTE: It is vital that a known good platen be in the unit.
3. Loosen the locking screws. Fig. 5-8
4. While printing, adjust the eccentric with a 10mm wrench. Turn the
eccentric clockwise to increase the density (darker impression) of the inner
side of the image or counter-clockwise to increase the density (darker
impression) of the outer side of the image.
5. Hold the eccentric in place with the 10mm wrench and tighten the locking
screws loosened in Step 3 above.
6. After adjustment, verify that label and ribbon are still tracking correctly.
7. If you are unable to get the unit to produce good print quality, proceed to
Section 5-3 Print Head Position Adjustment and perform the adjustment;
then return to this section and redo the Printhead Position Adjustment.
NOTE: You may have to do both of these adjustments concurrently
several times to achieve proper print quality and alignment.
NOTE: On this printer, the platen roller under the print head is adjustable with an
eccentric to make print quality and pressure consistent across the label.
