Switching Thermal Printer Between Interlaced And Non-Interlaced Input - Polaroid ID-3000 Repair Manual

Polaroid ID3000 Service Manual
Appendix 2: Switching Thermal Printer Between Interlaced and
Non-Interlaced Input.
ID3000 version 2.3 software supports both interlaced and non-interlaced input signals in the
Polaroid Color Thermal Printer. Ver. 2.2XX software supports non-interlaced input signal in
the Polaroid Color Thermal Printer.
Interlaced input is the default for all ID3000 systems. Interlaced input improves card
sharpness and eliminates the "scrunched' screen and Printer Syncronization step necessary for
the non-interlaced color thermal printer. The interlaced input yields a different size and
position print area than non-interlaced input. The vertical size does not change, however the
horizontal size changes from between 0.5 and 1.0mm. Also, the thermal sheet position
changes - mostly in the horizontal direction. The configuration variables for Card Size and
Offset must change when switching between interlaced and non-interlaced input.
The same application card layout will work with both an interlaced and non-interlaced print,
with almost no visible difference.
Modifying an ID3000 thermal system to use a TX1500 with non-interlaced input (from
interlaced input) involves both hardware and software changes.
Hardware Changes:
Dip switches in set A should be changed from interlaced to non-interlaced settings as
shown in Figure 1 (page A-5). These switches are located at the rear of the TX1500.
The front panel should be set as follows:
For interlaced input the following lights should be on:
POWER, READY, FRAME, RGB
For non-interlaced input the following lights should be on:
POWER, READY, FRAME, ANALOG
Software Changes:
(All changes are given by comments in the .CNF files).
In HOC_TP.CNF (in the C:\ID2DATA directory):
- Change the value of "HOC_TP_INTERLACE" to "N" (non-interlaced input).
- Change the vaues of the following variables to the non-interlaced values
given as comments in the file:
"HOC_TP_CARD1_XOFFSET", "HOC_TP_CARD1_YOFFSET",
"HOC_TP_CARD1_XSIZE", "HOC_TP_CARD1_YSIZE",
(and for 2-up cards)
