EICo 625 Files
- Eico 625 Tube Data double sided.pdf
- Eico 625 Tube Data.pdf
- Eico 625 Tube Data single sided.pdf
For EICo models 625 and 628.
Each of the three files has the same content.
One file is the straight file with consecutive pages. In all three files the pages are formatted for printing 5 1/2 by 8 1/2, two pages per sheet of 8 1/2 by 11 paper.
A second is for printing the file two pages to a sheet on a printer with double sided printing capability.
The third is for printing two pages to a sheet on a printer with only single sided printing capability. For this file, the first half of the file is printed, the output stack is flipped and the second half of the file is printed on the reverse side. With the second and third files.
With the second and third files, the sheets are cut in half and the pages can be bound with the proper order of pages. A GBC binding tool works well.
