Troubleshooting
107 HAMMER COIL <number> HOT
NOTE: 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.
One or more hammer coils are overheating. Inspect the printer environment for
severity. (See NOTE above.)
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.
Connect fan cables.
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 5–10 minutes.
If the message appears, replace the shuttle frame assembly.
7.
Run the “All E’s” print test for 5–10 minutes.
