Update 2 for Lotem 200K and Lotem 400 version 1.60.09

Note: The Height/Width Start Image Area Adjustment and the calibration of the parallel spoilers is essential for correct expose results and the proper function of the edge detection system.

Issues resolved

• The following edge detection problems were resolved:
  • The location and width of strips 1 and 2 were not precise
  • The system was sensitive to inconsistencies in the power supply
• Windows error message during shutdown in the Lotem 400 Xpose with UDRC configuration

Enhanced functionality

• Automatically defines strips 1 and 2
• Make the system less sensitive to power supply inconsistancies by improving the Drum power calibration value
• Supports Lotem 200K by defining the plate size with fixed parameters

Limitations

If you change any Media Definition parameters when a plate is on the drum, the Const Conversion Thickness to Focus Motor parameter is updated instead of the Focus parameters. To prevent this, before changing any parameter in the Media definition dialog box, verify that the media is not on the drum. This enables the Focus parameters to be automatically updated in the Edge Detection dialog box after new media is loaded on the drum.

Installing Update 2

Before loading Update 2, if you have made any mechanical changes to the pins, spoilers, or encoders, recalibrate the width start image area (see Height/Width Start Image Area Adjustment).

1. Close the Lotem Controller application.
2. Insert the CD in the CD-ROM drive. The update self-installs.
3. When the installer prompts you, select the relevant device type (Lotem 200K or Lotem 400).
