5.2.4.1 PG Adjustment Method
1. When replacing the Printhead, make sure that there is no Shipping Liquid sticking
on the Head surface, and then install the Head on the Carriage unit.
When removing/reinstalling the Printhead, completely wipe the
drops of ink off the metal frame section on the Head nozzle
surface with the ASP cleaner blade, which was kept clean, or a
clean, soft cloth (cloth that will not fluff), and then install the
Printhead to the Carriage unit.
If the drops of ink and Shipping Liquid have stuck to the Head
nozzle surface or Nozzle plate metal frame, fully be careful since
the PG cannot be adjusted accurately due to continuity that occurs
before contact of the Nozzle plate metal frame and gauge
adjustment portions.
2. Remove the Printer mechanism together with the Board unit from the Lower
housing, and place it on a level base.
"
Before starting PG adjustment, load all Ink cartridges into the
CR unit. If the Ink cartridges have not been loaded, the CR
weight will be instable and the PG may not be adjusted properly.
"
After removing the Printer mechanism, place a rag or ASP
waste ink pad under the Waste ink tube to prevent the desk from
being contaminated.
"
Put the Printer mechanism on the flat stable work table. If you
adjust the PG on the unstable table that the suface is not flat, the
PG adjustment is affected by the table condition and the PG can
not be adjusted correctly even if the adjustment lever over the
adjusment range. So, after put the Printer mechanism on the
table, check that the printer dose not move rumbly by shaking
the mechanism on the table.
3. Loosen the screws of the Adjust parallel bushes and Sub adjust parallel bushes.
4. Place the Release lever in the envelope mark position to increase the PG.
