4.7.2Printing area and image scaling4.7.2.1 Variable (reduction) printingFX-051 uses cut-sheet papers of A4, letter, and legal sizes.

FX-051 (US), for example, reads a document at 8 dots/mm x 7.7 lines/mm and sends it to remote TX-051 (US).

On the other hand, FX-051 (US) at receiving side receives the document, then converts the horizontal resolution from 8 dots/mm to 300 dots/inch and the vertical resolution from 7.7 lines/

mmto 784 lines/inch using image smoothing process. And also 784 to 1076 lines/inch (variable resolution) is available for vertical printing.

Since the available printing area of the printer is smaller than the paper size, document contents may be missed on both sides of the paper, or a document image having the same length as the printing paper may be split into separate pages in printing. To prevent these, FX-051 automatically adjust itself to the proper reduction ratio within the following range.

73 to 100% (US: Letter paper)78 to 100% (INT’L: A4 paper)
Note: The difference of the range depends on memory size and paper size.4.7.3Operation on alarm occurrence during printing

If a power failure or a printer alarm (including paper run-out alarm) occurs during printing of a received image, the image data already received and stored in the memory is regarded as no- paper received data. After the recovery from the failure, printing of the received image data automatically starts with the interrupted page, for FX-051 cannot reproduce the data for power failure.
