107 HAMMER COIL
<number> HOT
One or more hammer
coils are overheating.
The printer has sensor
circuits that sample the
operating temperature
of key components of
the print mechanism.
When higher than
normal temperatures
are sensed, print speed
is automatically reduced
by 50% and a COIL
HOT message is sent to
the LCD to inform the
operator. When the
coil(s) cool down, print
speed automatically
returns to 100% and the
message clears from
the LCD. This message
is normal for extremely
dense print jobs, such
as the Plot Test. If the
printer often prints at
half speed, it may be
operating in a severe
environment. A severe
environment is one with
an ambient temperature
at or above above 40
°
Celsius (104
°
Fahrenheit) or that is
dirty enough to create
blockage of the cabinet
fan vents. The printer
must never be run at
ambient temperatures
greater than 40
°
Celsius
(104
°
Fahrenheit). If the
printer is located in such
an environment,
relocate it to a cooler,
cleaner area or reduce
the size and duration of
the print jobs.
1.
Inspect the printer environment for
severity. 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
guide assembly 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 guide assembly 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 CMX controller board. Record the
message and return it with the defective
board.
