Following shows conditions that require this adjustment.
Table 5-10. Conditions that Head Gap Adjustment is required
No.
Conditions
Reason/Background
1
Head Exchange
If the head is exchanged, new head ID or
various characteristics are newly registered
in the C228 DRV board. Because of this, it
becomes necessary to change the head
gap adjustment value and Bi-D adjustment
value.
2
C228 DRV Board
Exchange
Head gap adjustment value and Bi-D
adjustment values are stored in the
EEPROM on the C228 board by parameter,
which is electrical Timing corrected data.
Therefore, if C228 DRV board is replaced,
since these data are all cleared, it becomes
necessary to register them again.

Other environmental
changes
In the ink jet printers, there are cases that
the adjusted data in the factory does not
work as it is supposed to under the
particular environments. As a more specific
example, there is a problem that the perfect
color matching becomes difficult by the
adjusted head gap values in the factory,
because ink viscosity changes in the
extremely cold or hot environments.
Considering this kind of possibilities, the
user is able to adjust directly from the driver
in the present EPSON ink jet printers.
Following shows procedure.
Step1.
Connect PC and printer with printer cable and turn both PC
and printer on.
Step2.
Type the following sentence on the DOS or DOS Prompt.
C:\mode lpt1:_retry=p
WARNING
Typing this sentence prevents PC from going to
Time Out Error, maintaining the scan mode until
the PC is able to recognize the printer ID correctly,
which comes back from the printer. If you ignore
this operation, the program may hang up on the
initial screen.
Step3.
Type as following on the DOS Prompt for exclusive
program Stylus Pro.5000.EXE attached with this manual.
A(In case of FD): \spro.5000.EXE
WARNING
When typing the sentence above, the program
hangs up on the initial screen, if the printer is not
turned on. In this case, start again from Step1.
