Half Speed Mode
This is a status message,
not an operational state. The
controller periodically
samples the operating
temperature of key
components of the print
mechanism. When higher
than normal temperatures
are sensed, the print speed
is automatically reduced by
50% and the message sent
the LCD. When the
components cool down, the
print speed returns to 100%
and the message clears.
This message is normal for
extremely dense print jobs,
such as “All Black” plot. If
this message often appears,
the printer may be operating
in a severe environment. A
severe environment has an
ambient temperature at or
above 40° Celsius (104°
Fahrenheit) or is dirty
enough to clog air vents. The
printer must never be run at
ambient temperatures
greater than 40° Celsius
(104° Fahrenheit). Inspect
the printer environment for
severity, and if the printer is
located in such an
environment relocate it to a
cooler, cleaner area.
1. Advise the user to move the
printer to cooler, cleaner location.
2. Check the kinds of print jobs the
user is running: look for very
dense graphics and layouts.
Advise the user to run jobs in
smaller batches.
3. Power off the printer. Remove the
paper path or pedestal top cover.
Check all fan cable connections.
4. Power on the printer. Verify that
all fans operate. Replace any fan
that does not operate.
5. Inspect vents and fan airways for
obstructions. Look underneath
cabinet models for items blocking
the cabinet exhaust vents.
Remove any obstructions from
vents and airways.
6. Install the paper path or pedestal
top cover. Load paper. Run the
“All E’s” print test for 5 to 10
minutes. If the message appears,
replace the shuttle frame
assembly.
7. Run the “All E’s” print test for 5 to
10 minutes. If the message
appears, replace the controller
board. Record the message and
return it with the defective board.
8. If the printer is a 1500 lpm model,
set the coil temperature (page
156).
HAM. COIL OPEN*
Hammer Coil Open.
Electrical malfunction of one
or more hammer coils.
1. Cycle power. If the message
appears, replace the shuttle
frame assembly.
2. Power on the printer. Run a print
test. If the message appears,
replace the controller board.
Record the message and return it
with defective board.
