Pre-Troubleshooting Procedures  
Preliminary Operating Checks  
Prior to troubleshooting a specific printer problem, you should
ensure that:
•The printer is being maintained on a regular basis as
described in Chapter 4.
•The customer is using acceptable media as specified in the
User ’s Manual.
•The printer is installed on a solid, level surface.
•The line voltage does not vary more than 10% from the
nominal rated value as specified on the Power Rating Label.
•The operating environment for the printer and paper is within
the temperature and humidity specifications listed in Chapter
1 of this manual.
•The printer is never exposed to ammonia fumes such as those
produced by diazo copiers, or office cleaning materials.
•The printer is not exposed to direct sunlight.
•Non-HP components (such as refilled toner cartridges, font
cartridges, and memory boards) are removed from the printer.

18 \bUX \fO \fN\fTThis message is displayed when the MIO ( \bUX \fO) card is
in the process of initializing. During initialization the MIO is

Display clears automatically (this may take up to a minute,
depending upon the card).
18 \bUX \fO NT RDY The MIO (\bUX \fO) 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

18 M\fO \fN\fT 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,

18 M\fO NOT RE\bDY The MIO card is not ready or not connected to a working
network. The serial and Bi-Tronics parallel ports will

documentation for troubleshooting.
20 MEM OVERFLOW
20 \fNSUFF\fC\fENT
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 PR\fNT OVERRUN
21 P\bGE 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  P\bGEPROTECT=[LTR,
LGL, or \b4], if applicable.
