 Some pictures used in this section are Stylus Photo R1800. The
adjustment method for L1800 is the same as the one for Stylus
Photo R1800.
 When only removing the Carriage Shaft, you do not need to
perform this adjustment. In that case, mark the position of the
rib on the Parallelism Adjust Bushing (Left/Right) before
removing them, and make sure to align the markings with the
ribs when installing them. (Refer to 3.4.5 Carriage Shaft /
Carriage Unit (p63).)

hands.
 If the Adjustment Gauge Plate surface is stained by ink or, etc
wipe it with a soft cloth.

C A U T I O N
 Before starting PG adjustment, completely wipe drops of ink
around the Print Head. Remaining drops of ink will stick to the
continuity measurement portion of the Adjustment Gauge, and
generate continuity before the continuity measurement portion
makes contact with the metal frame around the Print Head,
interrupting accurate PG Adjustment.
 As the ink in the Print Head may stick fast and damage the
Print Head during PG Adjustment, make the continuity time
detected with a tester as short as possible. (Maximum 3
minutes)
C A U T I O N
Place the printer on a level, warp-free table. Normal PG
Adjustment cannot be performed on a warped table.
