PROBLEM | PROBABLE CAUSES | CORRECTIVE ACTION | |
|
|
| |
|
| A. Check for 12VDC on computer pins 6 & | |
|
| 7. If NOT present AND motor is running, | |
| A. Failed computer. | replace computer. Check for 5VDC on | |
| terminals 3 & 4 of main heater relay and | ||
|
| pins 1 and 6 of computer. If NOT present | |
|
| at either point AND motor is running, | |
|
| replace computer. | |
| B. Broken/loose wire between computer and | B. Check for 12VDC on computer pins 6 & | |
| latch relay, or failed latch relay. | 7. If present and wiring is intact, replace | |
| latch relay. | ||
|
| ||
|
| C. Determine temperature of platen then | |
|
| measure main heater probe resistance at | |
Platen does not heat, but | C. Failed main heater probe. | pins 3 & 5 of | |
probe resistance is NOT approximately | |||
computer display is on. | |||
|
| equal to the corresponding resistance in | |
|
| the chart on Pages 24 and 25, replace the | |
|
| probe. | |
| D. Broken/loose wire between computer and | D. Check for 5VDC on terminals 3 & 4 of | |
| main heater relay AND on computer pins | ||
| main heater relay, or failed main heater | 1 & 6. If present on pins 1 & 6, but NOT | |
| relay. | on terminals 3 & 4, and wiring is intact, | |
|
| replace the main heater relay. | |
|
| E. Check for 5VDC on terminals 3 & 4 of | |
|
| main heater relay and for line voltage on | |
| E. Failed platen. | terminal 2 of main heater relay and | |
| terminal 4 of latch relay. If expected | ||
|
| ||
|
| voltage is present at all three points, | |
|
| replace the platen. | |
