Table 7-1	Printer Messages (continued)
Message		Symptoms and Recommendations
18 AUX IO INIT		This message is displayed when the MIO (AUX IO) card is
		in the process of initializing. During initialization the MIO is
		not active, but since the printer supports I/O switching, the
		printer remains on line and this becomes a status message.
		Display clears automatically (this may take up to a minute,
		depending upon the card).
18 AUX IO NT RDY		The MIO (AUX IO) card is not ready. See the user’s manual
		for the MIO card. The serial and Bi-Tronics parallel ports
		continue to operate normally. To clear the display, you must
		remove the card, and power-cycle the printer. The
		[Continue]* key does not clear the display.
18 MIO INIT		The MIO card is initializing. This is a status message.
		During initialization the MIO is not active, but since the
		printer supports I/O switching, the printer remains on line.
		Displays clears automatically (may take up to a minute,
		depending on the card).
18 MIO NOT READY		The MIO card is not ready or not connected to a working
		network. The serial and Bi-Tronics parallel ports will
		continue to operate normally. To clear the display, switch the
		printer OFF, remove the card and switch printer ON.
		[Continue]* will not clear the display. See MIO
		documentation for troubleshooting.
20 MEM OVERFLOW		Indicates a memory overflow. Too much data is being sent
		to the printer and the printer has run out of memory.
20 INSUFFICIENT		Pressing the [Continue]* key causes the printer to print only
MEMORY		the information it received. If the error persists, it may be
		necessary to simplify the print job (such as fewer fonts and
		less graphics information), or have the customer purchase
		additional memory.
21 PRINT OVERRUN		Indicates that the information being sent to the printer is too
		complex for the printer (the formatting capabilities of the
21 PAGE TOO COMPLEX		printer cannot keep up with the formatting instructions
		being sent to it by the computer).
		If the error persists, it may be necessary to simplify the job
		(reduce the number of characters, number of fonts used,
		number of pixels addressed, cursor repositions, or reduce
		addressing the same pixel location multiple times). This
		problem can also be resolved by adding at least one
		additional memory PCA, and setting PAGEPROTECT=[LTR,
		LGL, or A4], if applicable.
