8. There are vertical spacing problems when using continuous forms and Forms Tear Off.
The printer does not have a bail arm, so pages do not feed as high as printers with bail arms. The
first page does not line up correctly. Enter Menu Mode and disable Form Tear Off. Exit Menu
Mode. Deselect the printer and set the paper position, using the Micro Feed buttons (hold SHIFT
while pressing MICRO FEED UP or DOWN). Enter Menu Mode and enable Form Tear Off. Exit
Menu Mode.
9. The ALARM light is not on, but paper needs to be loaded.
If the ALARM light is off, the printer "thinks" that paper is loaded. To correct this problem, press and
release the SEL button. Then, hold the SHIFT button and press the RESET (Character Pitch)
button. The ALARM light will come on and you will be able to load paper.
10. The ALARM light is on and the Character Pitch 15 light is blinking.
This indicates a paper loading error. To stop the blinking light, press the SEL button. Before trying
to load paper, check to be sure that you have the paper lever in the correct position (BOT, TOP,
REAR) for the path that you are using.
CAUTION:
Always power OFF the printer before you turn the platen knob.
If the paper lever is in the correct position and you are using rear feed, lift up the paper separator
and check to be sure that the paper is properly on the tractors and has not jammed.
If the paper lever is in the correct position and you are using the optional bottom-feed push tractor,
check the bottom tractor unit to be sure that the paper is properly installed on the tractors and
that the paper has not jammed.
Once the paper is correctly loaded, press and release the SEL button, then hold the SHIFT button
and press the RESET (Character Pitch) button.
11. Word processor files do not print the way the MENU and front panel are set.
Before sending a file to the printer, many word processors send either an initialization string or an
I-Prime signal to the printer.
The initialization string contains codes that reset the printer to a default set of features. Otherwise,
the printer might accidentally print using features set for a previous job. These codes will override
the panel or MENU settings. To set your printer to ignore the reset codes, enter the printer MENU
(hold down the SHIFT button while pressing SEL/MENU button) and change the Reset Inhibit
item (in the Setup Group) to Yes. Please note that while this will stop the reset code from
resetting your printer, but other codes in the initialization string may still override the printer
MENU and / or front panel settings.
The I-Prime signal is sent over the parallel interface (pin 31) and will automatically override any
settings you have made using the front panel buttons. To eliminate this problem, enter the Menu
Mode (hold down the SHIFT button while pressing SEL/MENU button) and change the I-Prime
item (in the Parallel I/F Group) to Invalid.
