The Procedures

CLEARING PROGRAM

FROM FLASH Message

1. Status message: emulation software successfully loaded into printer RAM

and the checksum matched. The old program is now being deleted from

flash memory.

No action required.

CLOSE PLATEN Message

1. The forms thickness lever is open.

Load paper. Close the forms thickness lever.

2. Power off the printer. Remove the paper path or pedestal top cover.

Disconnect connector P107 from the CMX controller board. Check

continuity of the platen interlock switch from P107/PLO to the switch.

Replace the platen interlock switch assembly if it fails the continuity

test. (Refer to Appendix A, Switch Assembly, Platen Interlock.)

3. Check that the platen interlock switch is not loose.

Tighten the screws securing the platen interlock switch

4. Check the condition and tension of the platen open belt.

Adjust the platen open belt. Replace the belt if it is damaged.

5. Check the platen open pulley and the platen pulley for looseness.

Bottom out the platen open motor pulley on the motor shaft and

torque the 1/16 inch set screw to 9

± 2 inch-pounds (1.02 ± 0.23

N•m). Tighten the 7/64 inch setscrew in the platen shaft pulley, then

open and close the forms thickness lever and check that the platen

pulley setscrew does not hit the left ribbon guide.

6. Disconnect connector P106 from the CMX controller board. Check the

resistance of connector P106/PLAT M. (Refer to the Main Wire Harness

Test Tables in Appendix A.)

Replace the platen open motor if it fails the resistance test.

7. Run a print test.

If the message appears, replace the CMX controller board. Record

the message and return it with the defective board.

COIL HOT Message

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 “All Black”

plot. If the printer often prints at half speed, it may be operating in a

severe environment. A severe environment is one with an ambient
