• ThermoFlex^® Mid
• ThermoFlex Narrow

Background

In order to achieve the proper focus range for relatively thick plates, the optic lens assembly ("telescope") must move away from the drum. When the carriage moves, the top right screw on the spring jam (spacer) may collide with the machine chassis.

Replacing the spacers, described following, ensures that the screw on the spacer does not hit the chassis when the carriage moves to HP or EP.

Requirements

• 2 X spring jam 4 mm (part number 252-07059A)
• 1 X spring jam 3 mm (part number 252-07060A)
• Elevation jig (part number 291B6A743)

Procedure

To prevent this collision, replace the two 3 mm inside spring jams (spacers) with 4 mm spacers (252-07059A), and replace the right front spacer with a 3 mm spacer (252-07060A) that has a deeper indentation hole for the top screw, as follows:

1. From ThermoFlex Controller, click the Maintenance button. The carriage moves to middle position and the top front door opens.
2. Exit ThermoFlex Controller, turn off the device, and disconnect the power supply.
3. On the right side of the carriage assembly, remove the three hex screws that hold the spacers and remove the front and back 3 mm spacers.
4. Put spacer 252-07060A in front and spacer 252-07059A in back, and insert and tighten the three screws.
5. On the left side of the carriage assembly, remove the three hex screws that hold the spacers and remove the back 3 mm spacers.
6. Put spacer 252-07059A in back, and insert and tighten the three screws.
7. To prevent losing the elevation position, check Elevation with the elevation jig.
8. Perform all of the calibration tests, as listed in the Calibration Tests Overview .
