Note The D640 printer supports relevant parts of Baseline TIFF and selected elements of Extended TIFF. There are no private fields or values required by the printer. The TIFF standard does not contain any elements to indicate the termination of data. Therefore, termination of a TIFF file must be indicated by PJL universal escape sequences or the printer's I/O timeout configuration. Printing TIFF images TIFF images can be printed using the following methods: l setting the printer's control panel to recognize TIFF files (Emulation = TIFF or Auto). Auto is the recommended setting if you print files using more than one protocol (such as PCL or PS). l using commands in a print job Using the control panel On the printer's control panel, you can explicitly select TIFF emulation.

Chapter 3: Technical Reference
The D640 printer supports relevant parts of Baseline TIFF and
selected elements of Extended TIFF. There are no private fields or
values required by the printer.
Note
The TIFF standard does not contain any elements to indicate the
termination of data. Therefore, termination of a TIFF file must be
indicated by PJL universal escape sequences or the printer’s I/O
timeout configuration.
Printing TIFF images
TIFF images can be printed using the following methods:
setting the printer’s control panel to recognize TIFF files
(Emulation = TIFF or Auto). Auto is the recommended setting if
you print files using more than one protocol (such as PCL or PS).
using commands in a print job
Using the control panel
On the printer’s control panel, you can explicitly select TIFF
emulation. For details, see “TIFF emulation” on page 14.
When TIFF emulation is set, the following data items are valid:
A new TIFF file, starting with a 4-byte sequence $49492A00 or
$4D4D002A
PJL commands
Any other type of data is treated as an error.
On the printer’s control panel, you can also use the Auto emulation
setting to implicitly recognize TIFF files.
If Auto emulation is set, the printer recognizes either of the following
sequences as valid TIFF file headers and enters TIFF emulation
mode automatically, if this sequence is at the start of the print job.
$49492A00 or $4D4D002A
