4.2.3 Ink Charge
You must perform this operation after installing the “ASP Pr inthead” or ” ASP Printer Mec hanism ” in which
new “Printheads” are installed. “ASP Printheads” or “Printheads” installed in the “ASP Printer Mechanism ”
has shipping liquid filled in the cavity, and this operation is required to eject the liquid to r eplace it with the
ink. Therefore be sure to perform the initial ink charge operation whenever you replace the printhead,
since the lack of this oper ation might cause dot miss ing. The procedure and notes for this operation are
described below.
CAUTION
Avoid unnecessary initial ink charge operation, which consumes considerable amount of ink
;
(about one fifth of the ink cartridge capacity is consumed by this operation).
;
Do not turn the printer off before this program is completed. Otherwise, the ink dose not filled
enough in the cavity of the “Printhead”. in case of the power was turned off while this operation, do
this operation again by using this program.
;
This initial charge program is difference with the initial charge sequence which is carried out
automatically on the first power on time. This program carry out to chage the almost same value of
the ink which is used on the first power on initial charge sequence.
1. Set this program to FFD on your PC and turn the PC on.

4.2.6 BK.-Linear Adjustment
BK.-M Linear adjustment is required when replacing the printhead or disassem bling and assembling the
CR unit, and is performed to adjust the vertical position of the color head by using the black head for the
basis. This adjustment, which depends on the physical operation, is accomplished by moving the head
vertical adjust lever assembled to the right side of the CR unit. By running this program, the head vertical
adjustment pattern is printed to identif y the misalignment caused by the vertical gap between the Black
Head and Color Head. According to the printed pattern, adjust the gap by moving the head vertical
adjustment lever. Therefore this adjustment has no value to be written into the EEPROM on the C202
MAIN board. The adjustment procedure is as follows;
1. Set this program to FFD on your PC and turn the PC on.
2. The program automatically sets up and the following menu appears on the screen.
