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 20 INSUFFICIENT MEMORY Indicates a memory overflow. Too much data is being sent to the printer and the printer has run out of memory. Pressing the [Continue]* key causes the printer to print only 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 21 PAGE TOO COMPLEX Indicates that the information being sent to the printer is too complex for the printer (the formatting capabilities of the 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. *Press Go on the LJ5. 7-4 Troubleshooting
