[Step 6] When “’80 COLUMN...1, 136 COLUMN...2° is displayed, select 80 column or 136 column
for your machine.
●
[Step 7] When “BI-D...1, HEAD TILT...2, END...E” is displayed, select ‘“BI-D” by entering “l’”.
[Step 8] When “PRINTER
No.?” is displayed, enter the applicable printer number and press the return
key.
[Step 9] Print the odd-numbered lines at SPEEDO and even-numbered lines at SPEED1 both in
uni-directional print mode. In SPEED 1 mode, the compensation value of ‘“-4” is automatically
selected.
NOTE: The compensation value
“-4” is a specific value judged from our experience. The plus value
means that the print position will be shifted to the right, while the minus value to the left.
[Step 10] If the vertical elements in even-numbered lines and odd-numbered lines are aligned, press
the return key and go to Step 11. If they are not aligned, enter another value and press the
return key to check the output. Continue this procedure until they are aligned.
[Step 1 1] When the return key is pressed in Step IO, vertical lines are printed at
SPEEDl in bi-directional
print mode. The compensation value of “5” is automatically selected.
NOTE: The compensation value “5” is a specific value judged from our experience. The plus value
means that the print position will be shifted to the right, while the minus value to the left.
[Step 12] If the vertical elements in even-numbered lines and odd-numbered lines are aligned, press
the return key and go to Step 13. If they are not aligned, enter another value and press the
return key to check the output. Continue this procedure until they are aligned.
[Step 13] When the return key is pressed in Step
12,vertical Iines are printed at SPEED2 in bi-directional
print mode. The compensation value of “7” is automatically selected.
NOTE: The compensation value
“7” is a specific value judged from our experience. The plus value
means that the print position will be shifted to the right, while the minus value to the left.
[Step 14] If the vertical elements in even-numbered lines and odd-numbered lines are aligned, press
the return key and go to Step 15. If they are not aligned, enter another value and press the
return key to check the output. Continue this procedure until they are aligned.
[Step 15] When the return key is pressed in Step 14, the printing will be performed at each SPEED
and the adjustment is finished.
4.6 VOLUME VRI ADJUSTMENT ON MAIN BOARD
c)
f.$
The volume, VR1 on the MAIN board is used to adjust the reference pulse of the gate array, E05A48,
which controls the carriage motor. Since VR
1 has already been adjusted before shipment, additional
adjustment is not required.
However, when the gate alley,
E05A48 is replaced, adjust VR 1 in the following steps.
[Step 1] Connect the oscilloscope to the 7th pin of the gate array,
E05A48.
[Step 2] Turn on the printer power.
[Step 3] Verify that the printhead is capped and that the carriage motor is not rotating.
[Step 4] Turn
VR1 until 1 cycle of the continuous waveform in the oscilloscope shows 10* O. O5PS.
