Message Description Recommended Action
18 MIO NOT READY The MIO card is not ready. The Bi-Tronics
parallel port will continue to operate normally.
If the printer MIO card is operating correctly and
communicating with the network, this message will
disapear after approximately one minute and no
action is required. If the MIO card is unable to
communicate with the network, this message will
remain for five minutes and then go away. In this
case the printer is not communicating with the
network (even though the message is no longer
present). The problem may be a bad MIO card,
bad cable/connection on the network, or a network
problem. Contact your network administrator or
consult the network documentation that came with
your MIO card.
20 MEM OVERFLOW The printer received more data from the
computer than can fit in its available user
memory.
Press [Shift] + [Continue] to print the transferred
data (data loss may result), then: make more
memory available in the printer by removing some
fonts, macros, or any other data from memory; or,
simplify the page sent to the printer; or, install
additional memory. (Note, if AUTO CONT=ON the
printer will automatically continue printing when
this error occurs).
21 PRINT OVERRUN The data (dense text, rules, raster or vector
graphics) sent to the printer was too complex.
Press [Shift] + [Continue] to resume printing. (Note,
if AUTO CONT=ON the printer will automatically
continue printing when this error occurs). You may
lose some data. Try to simplify your print job. If
you must print the job “as is,” set PAGEPROTCT=ON in
the Job Menu, print the job, then return
PAGEPROTCT=AUTO.
Do not leave
PAGEPROTCT
set to
ON
as it will degrade performance.
22 PAR IO ERROR,
22 MIO ERROR
For Bi-Tronics parallel (PAR) configuration,
the computer and printer are not
communicating because of improper signal
protocols. This is an I/O buffer overrun error.
Parallel configuration: may mean a loose
cable connection or a bad or poor quality
cable.
MIO configuration: This is an I/O buffer
overrun error.
Press [Shift] + [Continue] to clear the error
message (data will be lost). If the error continues,
call your dealer or HP service representative.
Parallel configuration: check for loose cable; use
a high-quality cable (see “Accessories and
Options” in Chapter 1 or the
Getting Started Guide
for HP cable part numbers and information). (Note:
some non-HP parallel cables may be missing pin
connections).
If you are using an I/O other than the Bi-Tronics
parallel I/O, see the manual for that device or
contact your dealer. If you are on a network,
contact your network administrator.
40 MIO ERROR Indicates an abnormal connection break
occurred while transferring data from the
computer.
(If you are using an I/O other than the Bi-Tronics
parallel I/O, refer to the user’s manual for that
product.) Press [Shift] + [Continue] to clear the
error message.
If the following errors persist, call your HP-authorized service provider.
