POWER-UP FUNCTIONS
In addition to their normal functions, all of the control panel buttons perform
“special” functions if you hold them down while switching the power button on.

Short test mode
If the printer is turned on while the I ON LINE 1 button is pressed, the printer will enter the short self-test mode, with the “PI” message on the LCD display. The printer will print the version number of the printer’s ROM, followed by seven lines of the character set.
Each line will be offset by one character from the one before it. The final result will be something like Figure 4-3.

Since the self-test prints across the full width of the carriage, itisrecommended that the printer is loaded with the widest paper possible to avoid damage to the print head and/or platen.

Long test mode
If the printer is turned on while the [
PAPER FEED I button is pressed, the printer will enter the long self-test mode, with the “P2” message on the LCD display. The printer will print the version number of the printer’s ROM, the current Electronic DIP Switch (EDS) settingsand the current Dot Adjustment setting, followed by the entire character set printed in each font and pitch available.
The test repeats endlessly, so you must turn the power off to stop it.

Long self-test
Since the self-test prints across the full width of the carriage, it is recommended that the printer is loaded with the widest paper possible to avoid damage to the print head and/or platen. In addition, the total number of lines printed is considerable, more than can be accommodated on a single sheet, so fanfold paper is recommended for this test.
36
Print area test mode
By holding the I EJECT/PARK button down during power-up, theprinter will enter the print area test mode. You can find how many lines on your paper are available for printing with l/6-inch line feeding. The printer will show the
“P3” message on the LCD display and print the first line message on the paper, then print the last line message after feeding to the bottom of the page.
If you have loaded the fanfold paper, only the first line message is printed.
Pitch lock mode
By holding the EIEHl button down during power-up, the print pitch can only be selected from the control panel. This prevents software interference.
You will hear an acknowledging beep, and the printer will show the “P-LOCK” message on the LCD display as power comes on.
After the beep tone, you can set the printer off-line, select a print pitch, then return to on-line and start printing. The pitch you selected will show on the
LCD display and will not be reset or otherwise changed by any commands your software may issue.
Font lock mode
By holding the button during power-up, fonts can only be selected from the control panel. This prevents software interference. There will bean acknowledging beep and “F-LOCK” message on the LCD display. After which you can set the printer off-line, select a font, then return to the on-line state and begin printing. The selected font will not be changed by any commands your software may issue.
Font and Pitch lock mode
If you want to protect both the font and pitch settings from software changes, press both the and EEZZl buttons during power-up. There will be two acknowledging beep tones with “P-LOCK” and “F-LOCK” messages on the LCD display.
Pressing these buttons during power-up does not prevent you from making any number of changes later from the control panel.
37
Dot adjustment mode
This mode is used to adjust the vertical alignment of text and graphics on successive bi-directional passes.
After a period of time, your printer may work itself out of alignment on left and right printing passes, appearing most visibly during graphics printing.
This mode will probably be used very rarely.
1. Turn the printer off and then turn it on again while holding down the
I
EJECT/PARK I and I
ON LINE / buttons. The “dA” message will show on the display, and the printer will then print something like the following: x * x DOT

The printer will feed the paper forwards and backwards during this operation, allowing you to view the paper for optimum alignment.
To adjust the printing, use the I EJECT/PARK and [ PAPERFEED[ buttons.
The [ EJECT/PARK button will move the second pass to the left. The
I PAPERFEEDI button will move the second pass to the right.

When the two passes are aligned with each other to form one continuous line, the bi-directional alignment test is completed.

5. To change the mode for which the bi-directional adjustment is performed, press the I
ON LINE I button. This will cycle between “LQ”,
“DRAFT”, “DRAFT COND” and “BIT IMAGE”.
Repeat the process for all print modes

Hexadecimal dump
This feature is useful for programmers who are debugging printing programs and want to see the actual codes the printer is receiving, (Some computers change the codes the programmer intended.)
In this mode, all data received will be printed in a hexadecimal dump format, rather than the control codes being acted on as command codes.
This mode is accessed with the following procedure:
1. While holding both the I PAPERFEEDI and I EJECT/PARK buttons down, turn power ON. A beep tone will be heard and the “Hal” message on the display.
2. Begin printing. In place of the usualprintout you will get a formatted dump showing exactly what data the printer receives. Each line presents sixteen characters, their hexadecimal codes to the left and printable characters printed on the right.
3. At the end of the hexadecimal dump, set the printer off-line with the
ON LINE ] button. This is necessary to print the last line,
