C A U T IO N 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. CHECK P O IN T " 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.
